Users reported euphoria and calmness, a decrease and delay in heroin withdrawal symptoms, easy availability and low costs of obtaining tropicamide, and rapid onset of effects (Bersani et al, 2015). Large doses of tropicamide (up to 1 gram) have reportedly induced visual and auditory hallucinations, and chronic administration has resulted in anticholinergic toxicity, including agitation, hypertension, tachycardia, mydriasis, xerostomia, and mental confusion (Bozkurt et al, 2015; Spagnolo et al, 2013).

Life Support

    A) This overview assumes that basic life support measures have been instituted.

Clinical Effects

    0.2.1) SUMMARY OF EXPOSURE
    A) USES: The anticholinergic toxidrome refers to a set of signs and symptoms that occur with overdose of antagonists of the muscarinic cholinergic receptors. It can occur after poisoning from many pharmaceuticals and from naturally occurring alkaloids found in many plants. These medications are commonly used as sleep aids, antispasmodics (gastrointestinal and urinary), antihistamines, and ophthalmic cycloplegics and to treat Parkinson disease. This class of drugs is occasionally abused (mostly by adolescents) for its hallucinogenic effects.
    B) PHARMACOLOGY: Competitive antagonist of M1 and M2 muscarinic cholinergic receptor. Toxic effects from antagonism of the nicotinic cholinergic system is not a component of the syndrome. In general, the desired pharmacologic effects occur when only the peripheral muscarinic receptors are antagonized and there are no central antimuscarinic effects.
    C) TOXICOLOGY: Is an extension of the pharmacologic effects, which is due to extensive antagonism of the central and peripheral muscarinic acetylcholine receptors.
    D) EPIDEMIOLOGY: Poisoning is common but rarely severe. Toxicity may occur via oral, parenteral, or dermal route. Systemic anticholinergic effects have occasionally developed after use of ophthalmic preparations, mostly in young children.
    E) Refer to the following managements for more information about specific anticholinergic agents:
    1) DIPHENHYDRAMINE AND RELATED AGENTS
    2) PLANTS-ANTICHOLINERGIC
    3) ANTIHISTAMINES
    F) WITH THERAPEUTIC USE
    1) COMMON: Dry mouth, urinary retention, and constipation are commonly seen.
    G) WITH POISONING/EXPOSURE
    1) MILD TO MODERATE TOXICITY: Somnolence, anticholinergic effects of mydriasis, flushing, fever, dry mouth, decreased bowel sounds, and tachycardia are characteristic. Mild hypertension, nausea and vomiting are also common after overdose. Agitation, confusion, and hallucinations may develop with moderate poisoning.
    2) SEVERE TOXICITY: Severe effects may include agitated delirium, psychosis, hallucinations, seizures, hyperthermia, and coma. Some drugs that cause the anticholinergic toxidrome (eg, diphenhydramine) may cause QRS widening, and ventricular dysrhythmias due to sodium channel antagonism, but this is not due to the anticholinergic effects. Rhabdomyolysis and renal failure may rarely develop in patients with prolonged agitation, coma, or seizures.
    0.2.3) VITAL SIGNS
    A) WITH POISONING/EXPOSURE
    1) Vital sign changes include tachycardia and hypertension. Both hyperthermia and hypothermia have been reported, but hyperthermia is more common. Hypotension is reported rarely.
    0.2.20) REPRODUCTIVE
    A) Aclidinium bromide, atropine, atropine/pralidoxime chloride, albuterol sulfate/ipratropium bromide, belladonna alkaloids (atropine sulfate, hyoscyamine sulfate, and scopolamine hydrobromide)/phenobarbital, belladonna/opium, biperiden hydrochloride, fesoterodine fumarate, glycopyrrolate (oral forms only), glycopyrrolate/formoterol fumarate, hyoscyamine sulfate, methscopolamine bromide, olodaterol/tiotropium bromide, orphenadrine citrate, propantheline bromide, scopolamine hydrobromide, tiotropium bromide, tolterodine tartrate, umeclidinium, and vilanterol/umeclidinium are classified as FDA pregnancy category C. Dicyclomine hydrochloride, glycopyrrolate (IV form only), ipratropium bromide, mepenzolate bromide, and oxybutynin are classified as FDA pregnancy category B.
    B) Anticholinergic agents may suppress lactation. Dicyclomine hydrochloride and hyoscyamine sulfate are excreted in human breast milk.
    C) In animal reproduction studies, glycopyrrolate, ipratropium bromide, and tiotropium bromide decreased fertility.
    0.2.21) CARCINOGENICITY
    A) At the time of this review, the manufacturer does not report any carcinogenic potential of indacaterol/glycopyrrolate or glycopyrrolate/formoterol in humans.

Laboratory Monitoring

    A) Monitor vital signs (including temperature) and mental status.
    B) No specific lab work is needed in most patients.
    C) Monitor creatinine phosphokinase in patients with prolonged agitation, seizures, or coma.
    D) Monitor renal function and urine output in patients with rhabdomyolysis.
    E) Obtain an ECG and institute continuous cardiac monitoring in patients with moderate to severe toxicity (i.e., agitation, delirium, seizures, coma and hypotension).

Treatment Overview

    0.4.2) ORAL/PARENTERAL EXPOSURE
    A) MANAGEMENT OF MILD TO MODERATE TOXICITY
    1) The vast majority of pharmaceutical overdoses that produce the anticholinergic toxidrome require only supportive care; administer activated charcoal if the patient presents shortly after ingestion; sedate patients with benzodiazepines for agitation and delirium. Hypertension and tachycardia are generally mild and well tolerated, and do not require specific treatment. Physostigmine can be used to establish the diagnosis; it may help avoid an invasive, costly work-up, but should only be given in a setting where intensive monitoring and resuscitation is possible, and should NOT be given if the history or ECG (QRS widening) suggests tricyclic antidepressant poisoning.
    B) MANAGEMENT OF SEVERE TOXICITY
    1) Orotracheal intubation for airway protection should be performed early. May benefit from gastric lavage if the patient presents soon after a large ingestion; administer activated charcoal. GI decontamination should be performed only in patients who can protect their airway or who are intubated. Severe delirium may develop and require large doses of benzodiazepines for sedation. Seizures (may progress to status epilepticus) may require aggressive use of benzodiazepines, propofol and/or barbiturates. Monitor core temperature and treat hyperthermia with aggressive benzodiazepine sedation to control agitation, and external cooling. Clinical manifestations may be prolonged due to prolonged absorption in the setting of anticholinergic ileus.
    C) DECONTAMINATION
    1) PREHOSPITAL: Not recommended because of the potential for somnolence and seizures. For dermal exposure, wash skin thoroughly.
    2) HOSPITAL: Activated charcoal if recent, substantial ingestion, and patient able to protect airway. Consider gastric lavage in recent, life threatening ingestion, protect airway first.
    D) AIRWAY MANAGEMENT
    1) Protect airway early in patients with severe intoxication (i.e., seizures, severe delirium or hyperthermia).
    E) ANTIDOTE
    1) Physostigmine is indicated to reverse the CNS effects caused by clinical or toxic dosages of agents capable of producing anticholinergic syndrome; however, long lasting reversal of anticholinergic signs and symptoms is generally not achieved because of the relatively short duration of action of physostigmine (45 to 60 minutes). It is most often used diagnostically to distinguish anticholinergic delirium from other causes of altered mental status. CAUTION: If tricyclic antidepressants are coingested, physostigmine may precipitate seizures and dysrhythmias. DOSES: ADULT: 2 mg IV at a slow controlled rate, no more than 1 mg/min. May repeat doses at intervals of 10 to 30 min if severe symptoms recur. For patients with prolonged anticholinergic delirium consider a continuous infusion, start at 2 mg/hr and titrate to effect. CHILD: 0.02 mg/kg by slow IV injection, at a rate no more than 0.5 mg/minute. Repeat dosage at 5 to 10 minute intervals as long as the toxic effect persists and there is no sign of cholinergic effects. MAXIMUM DOSAGE: 2 mg total.
    F) SEIZURE
    1) Intravenous benzodiazepines; add propofol or barbiturates if seizures persist or recur.
    G) BODY TEMPERATURE ABOVE NORMAL
    1) Control agitation with benzodiazepines, initiate aggressive external cooling measures (i.e., remove patient's clothing, cover with a damp sheet or spray skin with water and direct fan at the patient’s skin to enhance evaporation).
    H) PSYCHOMOTOR AGITATION
    1) Sedate patient with benzodiazepines as necessary; large doses may be required.
    I) ENHANCED ELIMINATION
    1) Hemodialysis and hemoperfusion are of no value in this setting because of the large volume of distribution.
    J) PATIENT DISPOSITION
    1) HOME CRITERIA: Asymptomatic children (other than mild drowsiness or stimulation) with acute inadvertent ingestion may be monitored at home.
    2) OBSERVATION CRITERIA: Patients with deliberate ingestions and symptomatic patients should be sent to a health care facility for observation for 6 to 8 hours.
    3) ADMISSION CRITERIA: Patients with significant persistent central nervous system toxicity (i.e., hallucinations, somnolence, delirium, coma), or persistent tachycardia should be admitted. Patients with coma, seizures or delirium should be admitted to an intensive care setting.
    4) CONSULT CRITERIA: Consult a poison center or medical toxicologist for assistance in managing patients with severe toxicity (i.e., seizures, severe delirium, coma), or in whom the diagnosis is not clear.
    K) PITFALLS
    1) Physostigmine is generally not advised for long term management as anticholinergic effects generally recur 30 to 45 minutes after physostigmine administration. Anticholinergic toxicity may be prolonged secondary to decreased gastrointestinal motility leading to prolonged absorption.
    L) PHARMACOKINETICS
    1) While the exact pharmacokinetics will vary with a particular poison, the majority of poisons that cause anticholinergic symptoms will have a rapid onset and long duration of effect.
    M) DIFFERENTIAL DIAGNOSIS
    1) Anticholinergic poisoning from other substances, sympathomimetic poisoning (should have less mydriasis, usually no visual hallucinations, usually have moist skin), CNS infection, or ethanol/benzodiazepine/barbiturate withdrawal.

Range Of Toxicity

    A) ADULTS: Varies with the specific medication. In general, patients will have to ingest large doses of plant products (or make a tea) to develop symptoms.
    B) THERAPEUTIC DOSE: Varies with the specific medication.

Vital Signs

    3.3.1) SUMMARY
    A) WITH POISONING/EXPOSURE
    1) Vital sign changes include tachycardia and hypertension. Both hyperthermia and hypothermia have been reported, but hyperthermia is more common. Hypotension is reported rarely.
    3.3.3) TEMPERATURE
    A) WITH THERAPEUTIC USE
    1) HYPERTHERMIA
    a) Hyperthermia occurs more commonly than hypothermia.
    1) SCOPOLAMINE/CASE REPORT: A 23-year-old woman presented with extreme hyperpyrexia, as well as pupil dilation, tachycardia, hot dry skin, and perioral cyanosis after administration of scopolamine 0.4 mg intravenously (Torline, 1992).
    2) SCOPOLAMINE/CASE REPORT: An 83-year-old woman presented to the emergency department with a decreased level of consciousness (Glasgow Coma Scale score of 8), and intermittent myoclonus after ingesting a single 10-mg dose of scopolamine instead of the prescribed butylscopolamine 10 mg three times daily. Vital signs demonstrated hypertension (167/82 mmHg), tachycardia (127 beats/min) and hyperthermia (38 degrees C). Bilateral mydriasis that was unresponsive to light, and a tetrapyramidal syndrome with myoclonus of the left leg and hypertonia of the extremities were also noted. Following administration of a pyridostigmine infusion and supportive care, the patient gradually improved and was discharged a few days later with baseline mild cognitive deficit (Van de Velde et al, 2015).
    3) SCOPOLAMINE/CASE REPORT (INFANT): A 6-month-old infant developed seizures, hyperpyrexia, pupil dilation, hyperreflexia, and diminished bowel sounds after being given a scopolamine-like compound to control diarrhea. Signs and symptoms resolved 48 hours later following supportive treatment (Banner, 1983).
    2) HYPOTHERMIA
    a) ATROPINE/CASE REPORT (CHILD): Temperatures of 34 degrees C and 34.4 degrees C were reported in a 14-year-old boy 1 to 2 hours after a total dose of atropine sulfate 0.8 mg intravenously on 2 separate occasions (Lacouture et al, 1983).
    B) WITH POISONING/EXPOSURE
    1) HYPOTHERMIA
    a) ATROPINE/CASE REPORT (ADULT): A 65-year-old man who accidentally ingested approximately 3 mg of atropine subsequently developed facial warmth and flushness, restlessness, hyperactivity, dry tongue and mouth, speech dysphasia, and hypothermia. Blood pressure was 190/100 mmHg and pupils were dilated with hypertonicity of limbs and reflexes. Following treatment with chlorpromazine and paraldehyde, the patient became calm and after 24 hours was fully oriented and relaxed (Wood & Haq, 1971).
    3.3.5) PULSE
    A) WITH POISONING/EXPOSURE
    1) Tachycardia is a common anticholinergic effect.
    a) ATROPINE/CASE REPORT: Three children overdosed with atropine developed anticholinergic effects including tachycardia of 130 to 150 beats/min. The majority of signs and symptoms and rapid pulse rate resolved after 48 hours (Arthurs & Davies, 1980a).
    b) ORPHENADRINE/CASE REPORT: A 2-year-old child presented with seizures and a rapid, irregular pulse of approximately 180 beats/min after ingesting 28 orphenadrine tablets. Symptoms resolved several days later following supportive treatment (Stoddart et al, 1968).

Heent

    3.4.3) EYES
    A) WITH THERAPEUTIC USE
    1) Mydriasis is common and is associated with blurred vision from loss of accommodation reflexes (Van de Velde et al, 2015; Muttray et al, 2012; Boyd et al, 1997; Myers et al, 1997; Speich & Haller, 1994; Torline, 1992; Nogue et al, 1991; Banner, 1983; Bryson et al, 1978).
    a) HOMATROPINE/CASE REPORT (CHILD): An 11-year-old child experienced widely dilated pupils, as well as ataxia, visual hallucinations, flushed face, and dry mouth, after the instillation of homatropine hydrobromide 2% ophthalmic solution, 1 drop in each eye 6 times at 10-minute intervals. Signs and symptoms resolved 24 hours later following supportive treatment (Hoefnagel, 1961).
    B) WITH POISONING/EXPOSURE
    1) SUMMARY: Anisocoria and glaucoma have been described as a result of inadvertent exposure.
    2) ANISOCORIA
    a) TRANSDERMAL SCOPOLAMINE: Unilateral and bilateral pupillary dilation and impaired visual acuity have been described in patients who accidentally contaminated their eye or contact lenses after using a transdermal scopolamine patch. These effects were transient, gradually improving over 2 to 3 days (Thiele & Riviello, 1995; Rubin et al, 1990; Hughes & Zaloga, 1989; Patterson et al, 1986; Price, 1985; McCrary & Webb, 1982).
    b) Leakage from a mask nebulizing salbutamol and ipratropium and exposure to an anti-rash powder containing 2% diphemanil methylsulphate have been implicated in causing unilateral dilated pupils (Silbert & Edis, 1991; Helprin & Clarke, 1986).
    c) ATROPINE/CASE REPORT: A 7-year-old child was given aerosolized albuterol with atropine, via a mask, to treat asthma. The mask was slightly angled away from his face, allowing the mist to pass over his left eye. One hour later, the patient developed anisocoria. The atropine was then discontinued from his aerosol treatments, and the anisocoria resolved 40 hours later (Nakagawa et al, 1993).
    d) PROPANTHELINE/CASE REPORT: Two women presented with unilateral mydriasis after using propantheline bromide lotion as an antiperspirant and getting some in the affected eye. The dilation disappeared after a few days (Nissen & Nielsen, 1977).
    e) SCOPOLAMINE/CASE REPORT: A 55-year-old man developed mydriasis and ocular hypertension that lasted for 6 weeks following occupational exposure to dust of a scopolamine-related test agent (Muttray et al, 1994).
    3) GLAUCOMA
    a) ATROPINE/CASE REPORT: Two patients developed unilateral angle closure glaucoma after receiving aerosolized atropine to treat COPD. Both patients were treated with pilocarpine to reduce the pressure, followed by laser iridotomy after stabilization (Berdy et al, 1991).
    b) IPRATROPIUM: Bilateral closed-angle glaucoma has been reported in patients receiving ipratropium by nebulization. Use of a tight-fitting mask, properly placed to avoid eye contact, or use of a spacer device has been suggested to avoid absorption of the drug across the cornea (Mulpeter et al, 1992; Packe et al, 1984; Malani et al, 1982) .
    c) TIOTROPIUM: A 46-year-old man developed acute closed-angle glaucoma of his right eye approximately 4 hours after touching his eye with the contents of a capsule containing tiotropium. The intraocular pressures of his right and left eye were 42 mmHg and 14 mmHg, respectively, and a gonioscopic exam of his right eye showed narrow iridocorneal angle. Treatment with acetazolamide, pilocarpine 1% eye drops, and mannitol 20% infusion resolved all signs and symptoms within 12 hours (Oksuz et al, 2007).
    4) MYDRIASIS
    a) CLIDINIUM: Mild mydriasis and persistent sinus tachycardia were reported in a 24-year-old man following 2 overdose ingestions, separated by 90 minutes, of a combination medication containing chlordiazepoxide 5 mg and clidinium 2.5 mg (amounts ingested per overdose: chlordiazepoxide 50 mg and clidinium 25 mg). With supportive care, the patient recovered and was discharged without sequelae (Richardson & Edwards, 2009).
    3.4.6) THROAT
    A) WITH THERAPEUTIC USE
    1) Dry mouth may occur as a result of a decrease in secretions from salivary glands. A reduction of secretions in the pharynx, bronchi, and nasal passages may also be noted.
    a) Dry mouth and skin are common adverse anticholinergic effects that are dose-related (Muttray et al, 2012; Gregory et al, 2010; Myers et al, 1997; Boyd et al, 1997; Handerhan, 1994; Boyson, 1988) .
    2) Decreased secretion in the pharynx, bronchi, and nasal passages may occur as an adverse anticholinergic effect (Myers et al, 1997; Nogue et al, 1991; Richmond & Seger, 1985) .

Cardiovascular

    3.5.2) CLINICAL EFFECTS
    A) HYPERTENSIVE EPISODE
    1) WITH POISONING/EXPOSURE
    a) Hypertension is common and may be delayed in onset.
    b) ATROPINE/CASE REPORT: A 65-year-old man who accidentally ingested approximately 3 mg of atropine subsequently developed facial warmth and flushness, restlessness, hyperactivity, dry tongue and mouth, speech dysphasia, and hypothermia. Blood pressure was 190/100 mmHg and pupils were dilated with hypertonicity of limbs and reflexes. Following treatment with chlorpromazine and paraldehyde, the patient became calm and after 24 hours was fully oriented and relaxed (Wood & Haq, 1971).
    c) ATROPINE/CASE REPORT: A 36-year-old woman experienced hypertension (150/100 mmHg), tachycardia, visual hallucinations, and confusion after ingesting Indian tonic water. Analysis of the tonic water revealed that it contained substantial quantities of atropine (Boyd et al, 1997).
    d) OXYBUTYNIN/CASE REPORT: A 34-year-old woman experienced hypertension and tachycardia after ingesting 100 mg of oxybutynin. Seventy-two hours later, signs resolved with supportive treatment (Banerjee et al, 1991).
    e) SCOPOLAMINE-TAINTED HEROIN: Hypertension and tachycardia were reported in several patients following insufflation of scopolamine-tainted heroin (Perrone et al, 1999; Hamilton et al, 1995).
    B) VASODILATATION
    1) WITH POISONING/EXPOSURE
    a) Peripheral cutaneous vasodilatation (facial flushing) may occur.
    b) ATROPINE/CASE REPORT: A 65-year-old man who accidentally ingested approximately 3 mg of atropine subsequently developed facial warmth and flushness, restlessness, hyperactivity, dry tongue and mouth, speech dysphasia, and hypothermia. Blood pressure was 190/100 mmHg and pupils were dilated with hypertonicity of limbs and reflexes. Following treatment with chlorpromazine and paraldehyde, the patient became calm and after 24 hours was fully oriented and relaxed (Wood & Haq, 1971).
    c) DIPHENIDOL/CASE SERIES: A retrospective analysis of diphenidol overdoses reported that facial flushing was a common toxic effect that occurred in 10 of 21 patients following diphenidol overdose ingestions. All patients recovered within 12 hours (Yang & Deng, 1998).
    d) HYOSCYAMINE/CASE SERIES: Flushed skin occurred in 5 infants following overdose ingestions of hyoscyamine to treat colic (Myers et al, 1997).
    C) HYPOTENSIVE EPISODE
    1) WITH POISONING/EXPOSURE
    a) DIPHENIDOL/CASE REPORT (CHILD): Hypotension occurred in a 2-year-old child approximately 2 hours after ingesting 225 mg of diphenidol. The child also experienced tachycardia, recurrent seizures, respiratory failure, and deep coma. He subsequently died due to profound shock, despite aggressive supportive measures (Yang & Deng, 1998).
    D) SINUS TACHYCARDIA
    1) WITH THERAPEUTIC USE
    a) Tachycardia is a common anticholinergic effect and may be cyclical and delayed in onset (Joseph et al, 1991; Arthurs & Davies, 1980; Adcock, 1971; Hoefnagel, 1961).
    b) HOMATROPINE/CASE REPORT (ADULT): Topical homatropine eyedrops were the implicated cause of tachycardia (160 to 180 beats/min) and syncope in an 84-year-old woman. Attacks of symptoms occurred within 1 hour of instilling the drops (Reid & Fulton, 1989).
    2) WITH POISONING/EXPOSURE
    a) Tachycardia is a common anticholinergic effect and may be cyclical and delayed in onset (Joseph et al, 1991; Arthurs & Davies, 1980; Adcock, 1971; Hoefnagel, 1961).
    b) DIPHENIDOL/CASE SERIES: Tachycardia was reported in 6 children following diphenidol overdose ingestions ranging from 25 mg to 800 mg. In most cases, recovery occurred following supportive care (Yang & Deng, 1998).
    c) HYOSCYAMINE/ CASE SERIES: Tachycardia (heart rates ranging from 155 beats/min to 220 beats/min) occurred in 5 infants who were given hyoscyamine sulfate in overdose amounts of 2 to 4 mL (1 dropperful is equivalent to 1 mL or 20 drops) to treat colic. The patients recovered within 24 hours following supportive care (Myers et al, 1997).
    d) ATROPINE: Sinus tachycardia was reported in a child and an adult after drinking Indian tonic water. Analysis of a sample of the Indian tonic water showed that it contained substantial quantities of atropine (Boyd et al, 1997).
    e) ORPHENADRINE/ CASE REPORT (CHILD): A 2-year-old child presented with seizures and a rapid, irregular pulse of approximately 180 beats/min with associated hypotension (50 systolic) after ingesting 28 orphenadrine tablets. Symptoms resolved several days later following supportive treatment (Stoddart et al, 1968).
    f) SCOPOLAMINE-TAINTED HEROIN: Tachycardia and hypertension were reported in several people following insufflation of scopolamine-tainted heroin (Perrone et al, 1999; Hamilton et al, 1995).
    g) TIOTROPIUM: A 74-year-old man with a history of COPD, atrial fibrillation, and renal insufficiency who was taking tiotropium 18 mcg daily as part of his medication regimen presented to a hospital with dyspnea and tachycardia (130 beats/min). After hospital admission, he received metoprolol which decreased his heart rate to 80 to 90 beats/min. Twenty-four hours later, he inadvertently received 5 tiotropium 18-mcg capsules via inhalation instead of the prescribed one 18-mcg capsule. Approximately 15 minutes later, the patient's heart rate increased to 160 beats/min. With IV administration of metoprolol and diltiazem, his heart rate returned to the 80s, although it continued to be difficult to control throughout his hospitalization (Gregory et al, 2010).
    h) CLIDINIUM: A 24-year-old man developed sinus tachycardia (110 to 125 beats/min) that persisted for 11 hours following 2 overdose ingestions, separated by 90 minutes, of a combination medication containing chlordiazepoxide 5 mg and clidinium 2.5 mg (amounts ingested per overdose: chlordiazepoxide 50 mg and clidinium 25 mg). With supportive care, the patient recovered and was discharged without sequelae (Richardson & Edwards, 2009).
    E) CONDUCTION DISORDER OF THE HEART
    1) WITH POISONING/EXPOSURE
    a) ORPHENADRINE/CASE REPORT (CHILD): Wide complex tachycardia unresponsive to lidocaine, precordial thump, and cardioversion were seen in a 3-year-old who may have ingested 1000 to 5000 mg of orphenadrine. IV physostigmine converted the patient to sinus tachycardia (Danze & Langdorf, 1991).
    b) Life-threatening dysrhythmias, cardiogenic shock, and cardiorespiratory arrest are rare but may occur (Freedberg et al, 1987).
    F) BRADYCARDIA
    1) WITH THERAPEUTIC USE
    a) ATROPINE/CASE REPORT: The administration of atropine 1 mg IV paradoxically caused bradycardia in a 49-year-old man with impaired AV conduction immediately after an inferior myocardial infarction (Ng & Nikolic, 1991).
    b) BENZTROPINE/CASE REPORT: Similar clinical effects were seen in a patient that had been given benztropine mesylate. The bradycardia disappeared after discontinuation of the drug (Voinov et al, 1992).
    c) TRIHEXYPHENIDYL/CASE REPORT: There is 1 reported case where administration of trihexyphenidyl paradoxically caused bradycardia (Blumensohn et al, 1986).

Respiratory

    3.6.2) CLINICAL EFFECTS
    A) SUFFOCATING
    1) WITH POISONING/EXPOSURE
    a) Respiratory depression and aspiration may occur in patients with seizures or mental status changes secondary to severe overdose (Stoddart et al, 1968).
    B) APNEA
    1) WITH POISONING/EXPOSURE
    a) DIPHENIDOL/CASE REPORT (CHILD): Respiratory failure with cyanosis occurred in a 2-year-old child following a diphenidol overdose ingestion of 225 mg. The patient subsequently died due to profound shock (Yang & Deng, 1998).

Neurologic

    3.7.2) CLINICAL EFFECTS
    A) DELIRIUM
    1) WITH THERAPEUTIC USE
    a) TRANSDERMAL SCOPOLAMINE: Therapeutic use of transdermal scopolamine patches has been linked to hallucinations, memory loss, disorientation, and agitation in adults (Elias & Abouleish, 1997; Mego et al, 1988; Rozzini et al, 1988) and in children (Lin et al, 2014).
    1) CASE REPORT: Two children (ages 4 and 6) presented to the emergency department with confusion, visual hallucinations, and incoherent speech. Vital signs and ECG demonstrated sinus tachycardia (heart rate of 100 bpm). Examination of the patients revealed a transdermal scopolamine patch behind the ear of each child, that had been applied 22 hours prior to presentation in order to prevent motion sickness. The patches were removed and, 6 hours later, their delirium persisted with increasing agitation. Following IM administration of physostigmine (0.02 mg/kg), the patients symptoms improved with complete resolution 18 hours later (Lin et al, 2014).
    b) BIPERIDEN/CASE REPORT (CHILD): A 15-year-old boy, initially diagnosed with gastroenteritis and receiving prochlorperazine therapy, experienced auditory and visual hallucinations, an altered mental status, disorientation, restlessness, and insomnia after receiving biperiden 5 mg intramuscularly followed by biperiden 2 mg orally 3 times daily for treatment of dystonia caused by the prochlorperazine. Prior to onset of delirium signs and symptoms, the prochlorperazine had been discontinued. With supportive care and discontinuation of biperiden therapy, the patient's delirium resolved and he was discharged approximately 2 days later (Wang et al, 2011).
    2) WITH POISONING/EXPOSURE
    a) CASE REPORT (OCULAR): Disorientation, asthenia, drowsiness, verbosity with incoherent speech, and light delirium occurred 195 minutes after 12 drops of an eye preparation, containing atropine 12 mg, phenylephrine 24 mg, and scopolamine 3 mg, were instilled over 1.5 hours in a 67-year-old woman (Kortabarria et al, 1990).
    b) SCOPOLAMINE-TAINTED HEROIN: Agitation, hallucinations, paranoia, and combativeness were reported in several people following insufflation of scopolamine-contaminated heroin. The patients recovered following benzodiazepine administration (Perrone et al, 1999) and physostigmine administration (Hamilton et al, 1995).
    c) SCOPOLAMINE/CASE REPORT: A 55-year-old man developed delirium and subsequent toxic encephalopathy following occupational exposure to a scopolamine-related substance. The delirium regressed within 1 day without treatment; however there was only partial regression of the encephalopathy over the following 3 years (Muttray et al, 1994).
    d) SCOPOLAMINE/CASE REPORT: Toxic psychosis from overdosage of Sominex(R) (containing scopolamine) occurred in a 27-year-old man following ingestion of 10 to 30 tablets. The patient developed symptoms of agitation, pressured speech, flushing, hyperpyrexia, mydriasis, and blurred vision. Confusion and disorientation with visual hallucinations were also observed. Psychotic behavior existed beyond the toxic phase, possibly unmasking an underlying schizophrenia. Signs and symptoms disappeared within 24 to 36 hours. Similar symptoms were reported in a second patient following ingestion of scopolamine in large amounts over a period of 3 days (Bernstein & Leff, 1967).
    e) TROPICAMIDE/CASE REPORT: A 22-year-old heroin addict, enrolled in a methadone replacement program, presented with palpitations. Vital signs revealed hypertension (160/90 mmHg) and tachycardia (120 beats/minute). Mydriasis and xerostomia were noted, and the patient was agitated, reporting visual and auditory hallucinations. Treatment with diazepam resulted in resolution of signs and symptoms. Interview of the patient revealed a 2-year history of intravenously injecting tropicamide 1% ophthalmic solution in order to attenuate signs and symptoms of opiate withdrawal. Initially, the patient administered an approximate dose of 0.5 g of tropicamide; however, it was discovered that increasing the dose up to 1 g resulted in visual and auditory hallucinations. Following several months of use, the patient experienced tropicamide dependence and progressively increased the dose up to 1.5 g, resulting in more severe anticholinergic effects. Administration of heroin or methadone immediately following tropicamide administration reportedly reduced the anticholinergic effects. At the time of presentation, the patient had been injecting up to 1.5 g tropicamide daily and using up to 0.5 g of heroin approximately once a week (Spagnolo et al, 2013).
    3) Disorientation, delirium, hallucinations, and paranoia associated with anxiety, agitation, and hyperactivity have been reported. Effects may occur following a therapeutic dose as well as an overdose (Beaver & Gavin, 1998; Boyd et al, 1997; Grace, 1997; Tomassoni & Prybys, 1995; Seger & Lawrence, 1995; Speich & Haller, 1994; Adcock, 1971).
    a) Hallucinations are usually visual (Fisher, 1991).
    B) AMNESIA
    1) WITH THERAPEUTIC USE
    a) Evidence of retrograde amnesia is often noted following the administration of atropine sulfate and homatropine ophthalmic drops in children (Barker & Soloman, 1990).
    b) SCOPOLAMINE/CASE STUDY: A group of 20 healthy male volunteers, who took 1.2 mg of scopolamine, were found to have impairment of immediate free recall. However, their mental rotation skills were unimpaired by cholinergic blockade (Rusted, 1988).
    2) WITH POISONING/EXPOSURE
    a) SCOPOLAMINE/CASE REPORT: A 42-year-old man experienced delirium, hallucinations, dilated pupils, tachycardia, and retrograde amnesia following possible scopolamine poisoning. Signs and symptoms resolved 24 hours later (Brizer & Manning, 1982).
    b) SCOPOLAMINE: Following scopolamine exposure, 3 cases of transient global amnesia (TGA) occurred, which is characterized by an abrupt deficit in memory for recent events usually associated with retrograde amnesia (Ardila & Moreno, 1991).
    C) SEIZURE
    1) WITH THERAPEUTIC USE
    a) ATROPINE/CASE REPORT (CHILD): A 3-month-old infant was hospitalized with generalized tonic-clonic seizures, tachycardia, mydriasis, and fever. Signs began 1.5 hours after atropine sulphate 1% ointment was instilled in his eyes to facilitate ophthalmologic examination. Neostigmine (0.12 mg IV) and diazepam were used to control signs, which subsequently resolved (Joseph et al, 1991).
    b) CYCLOPENTOLATE/CASE REPORT (CHILD): Seizures, facial flushing, and tachycardia occurred following instillation of cyclopentolate 1%, 1 drop in each eye, in a 4.5-year-old child with cerebral palsy and paraplegia without an epileptic focus (Fitzgerald et al, 1990).
    c) KETAMINE AND ATROPINE: Two patients developed generalized clonic seizures after receiving ketamine and atropine intramuscularly as preoperative medications (Burmeister-Rother et al, 1993).
    2) WITH POISONING/EXPOSURE
    a) CASE REPORT (INFANT): An 18-month-old infant experienced seizures, along with hyperpyrexia and pupil dilation, several hours after swallowing 23 Debendox(R) tablets. Each delayed-release tablet contained dicyclomine hydrochloride 10 mg, doxylamine succinate 10 mg, and pyridoxine hydrochloride 10 mg. The patient suffered cardiac and respiratory arrest following treatment with diazepam and paraldehyde (Meadow & Leeson, 1974).
    b) ATROPINE/CASE REPORT(CHILD): A 3-year-old child developed an exacerbation of akinetic seizures after the administration of atropine sulfate 1% eye drops, 1 drop in each eye twice daily for 4 days. Prior to receiving the eye drops, the patient experienced only 2 seizures in a 3-month period. Twenty-four hours after initiating therapy with the eye drops, the patient began to have an increase in seizures. Overall, the patient had a total of 92 akinetic seizures in 7 days (Wright, 1992).
    c) DIPHENIDOL/CASE SERIES: Seizures were reported in 4 children following diphenidol overdose ingestions with doses ranging from 175 to 800 mg. One child, who presented with recurrent seizures, hypotension, respiratory failure, and coma, died 2 days later (Yang & Deng, 1998).
    d) TROPENOL ESTER/CASE REPORT: A 40-year-old chemical worker experienced impaired coordination, drowsiness, and a generalized tonic-clonic seizure following suspected occupational dermal exposure to tropenol ester, a precursor to tiotropium bromide. The patient also developed mydriasis, photophobia, and a dry mouth. With supportive care, the patient recovered (Muttray et al, 2012).
    D) DYSTONIA

    a) BENZTROPINE: Acute dystonic reactions following recommended doses of benztropine, especially in children, have been reported (Howrie et al, 1986).
    b) TRIHEXYPHENIDYL/CASE SERIES: Trihexyphenidyl was used to treat 5 adult patients for focal or segmental dystonia; all 5 developed chorea. Doses ranged from 15 to 60 mg/day, and an association was found between advanced patient age and a lower dose causing chorea (Nomoto et al, 1987).
    E) DYSKINESIA
    1) WITH THERAPEUTIC USE
    a) BIPERIDEN AND TRIHEXYPHENIDYL: Two cases of dyskinesias occurred in patients following ingestions of biperiden and trihexyphenidyl, which resolved with the removal of the medications (Linazasoro, 1994).
    b) TRIHEXYPHENIDYL: Orobuccal dyskinesias occurred in a 60-year-old man 3 to 4 days after initiating therapy with trihexyphenidyl, 2 mg twice daily, for the treatment of Parkinson disease. The dyskinesia resolved after discontinuation of the medication (Hauser & Olanow, 1993).
    F) MYOCLONUS
    1) WITH POISONING/EXPOSURE
    a) SCOPOLAMINECASE REPORT: An 83-year-old woman presented to the emergency department with a decreased level of consciousness (Glasgow Coma Scale score of 8), and intermittent myoclonus after ingesting a single 10-mg dose of scopolamine instead of the prescribed butylscopolamine 10 mg three times daily. Vital signs demonstrated hypertension (167/82 mmHg), tachycardia (127 beats/min) and hyperthermia (38 degrees C). Bilateral mydriasis that was unresponsive to light, and a tetrapyramidal syndrome with myoclonus of the left leg and hypertonia of the extremities were also noted. Following administration of a pyridostigmine infusion and supportive care, the patient gradually improved and was discharged a few days later with baseline mild cognitive deficit (Van de Velde et al, 2015).
    G) COMA
    1) WITH POISONING/EXPOSURE
    a) ATROPINE/CASE REPORT (INFANT): A 5-week-old infant, through a dosing error, was given atropine 3.2 mg /kg body weight as treatment for colic. Twelve hours later, he lapsed into a coma. Signs resolved within 48 hours with supportive treatment (Pickford et al, 1991).
    b) ATROPINE/CASE REPORT: A 55-year-old woman became comatose after administration of a compounded ergotamine tartrate and caffeine suppository that inadvertently contained 25 mg of atropine sulfate instead of 0.25 mg atropine sulfate (Hadzija & Shrewsbury, 1997).
    c) CASE REPORT (CHILD - OCULAR): A 6-year-old child presented with coma, agitation, dilated pupils, dry skin and mouth, and tachycardia. Signs and symptoms appeared 1 hour after instillation, 2 drops in each eye, of ophthalmic solution containing atropine sulfate 2%, scopolamine bromhydrate 0.5%, and phenylephrine hydrochloride 4%. The patient regained cognitive functions 16 hours later with physostigmine treatment (Nadal et al, 1987).
    d) DIPHENIDOL/CASE REPORT (CHILD): A 2-year-old child ingested 225 mg of diphenidol (15 mg/kg) and developed tachycardia, hypotension, recurrent seizures, respiratory failure, and coma.

    1) Coma occurred in another child following an overdose ingestion of 800 mg diphenidol. The child recovered within 3 days, following intensive supportive care.
    H) DREAM DISORDER
    1) WITH THERAPEUTIC USE
    a) OXYBUTYNIN: Night terrors have been reported in children and adults following therapeutic administration of oxybutynin. Cessation of oxybutynin therapy resulted in complete recovery (Valsecia et al, 1998).
    I) IMPAIRED COGNITION
    1) WITH THERAPEUTIC USE
    a) In a study of 372 elderly people (older than 60 years of age), 30 (9.2%) anticholinergic drug users and 297 nonusers were evaluated to determine the potential of anticholinergic drugs as a cause of nondegenerative mild cognitive impairment. Drug users had significantly poorer simple reaction time, attention, immediate and delayed visuospatial memory, narrative recall, verbal fluency, and object naming and visuospatial construction compared with the nonusers. Twenty-four (80%) of 30 drug users met the criteria for mild cognitive impairment compared with 35% of the nonusers. The 2 highly significant predictors of mild cognitive impairment were anticholinergic drug use (odds ratio 5.12; 1.94 to 13.51; P=0.001) and age (1.09; 1.06 to 1.13, P<0.001). At 8-year follow-up, no difference in dementia rates between drug users (16%) and nonusers (14%) was observed (Ancelin et al, 2006).
    J) DISTURBANCE OF CONSCIOUSNESS
    1) WITH POISONING/EXPOSURE
    a) SCOPOLAMINE/CASE REPORT: An 83-year-old woman presented to the emergency department with a decreased level of consciousness (Glasgow Coma Scale score of 8), and intermittent myoclonus after ingesting a single 10-mg dose of scopolamine instead of the prescribed butylscopolamine 10 mg three times daily. Vital signs demonstrated hypertension (167/82 mmHg), tachycardia (127 beats/min) and hyperthermia (38 degrees C). Bilateral mydriasis that was unresponsive to light, and a tetrapyramidal syndrome with myoclonus of the left leg and hypertonia of the extremities were also noted. Following administration of a pyridostigmine infusion and supportive care, the patient gradually improved and was discharged a few days later with baseline mild cognitive deficit (Van de Velde et al, 2015).

Gastrointestinal

    3.8.2) CLINICAL EFFECTS
    A) DRUG-INDUCED ILEUS
    1) WITH THERAPEUTIC USE
    a) Decreased gastric motility and diminished bowel sounds commonly occur with anticholinergic toxicity (Fahy et al, 1989; Freedberg et al, 1987; Goldfrank et al, 1982).
    b) BENZTROPINE/CASE REPORT: Esophageal atony and dilatation and distention of the colon occurred in a 51-year-old man following ingestion of thiothixene, 10 mg 3 times daily, and benztropine, 2 mg twice daily. Effects resolved 2 days after discontinuation of the medications (Woodring et al, 1993).
    c) There have been reported cases of paralytic ileus developing in patients following the oral or intravenous administration of atropine, mesoridazine, or benztropine mesylate (Beards et al, 1994; Van Meurs et al, 1992; Beatson, 1982; Wade & Ellenor, 1980) .
    d) IPRATROPIUM BROMIDE/CASE REPORT: A case of paralytic ileus following the use of nebulized ipratropium bromide has been described. The patient recovered several days after discontinuation of the drug (Markus, 1990).
    B) WEIGHT LOSS FINDING
    1) WITH POISONING/EXPOSURE
    a) TROPICAMIDE/CASE REPORT: Severe weight loss (15 kg in one year) was reported in two patients (37-year-old and 38-year-old men), with a history of heroin use, after intravenously injecting 1% tropicamide ophthalmic solution with heroin several times daily. The patients reported that administration of tropicamide resulted in an increase and prolongation of heroin's effect, and the desire to use heroin decreased. In addition to the weight loss, the patients also experienced hallucinations, blurred vision, dissociation, and impaired concentration. Both patients gradually recovered following cessation of tropicamide administration and treatment with buprenorphine and naloxone for opioid withdrawal symptoms (Bozkurt et al, 2015).

    3.20.2) TERATOGENICITY
    A) LACK OF INFORMATION
    1) ATROPINE/PRALIDOXIME CHLORIDE
    a) At the time of this review, no data were available to assess the teratogenic potential of this agent (Prod Info DuoDote(R) intramuscular injection solution, 2011).
    2) CLIDINIUM BROMIDE

    3) IPRATROPIUM BROMIDE
    a) At the time of this review, no data were available to assess the teratogenic potential of this agent (Prod Info Atrovent(R) nasal spray, 2011; Prod Info ATROVENT(R) HFA oral inhalation aerosol, 2010; Prod Info ipratropium bromide 0.02% inhalation solution, 2007).
    4) TIOTROPIUM BROMIDE
    a) At the time of this review, no data were available to assess the teratogenic potential of this agent (Prod Info SPIRIVA(R) RESPIMAT(R) oral inhalation spray, 2014).
    5) UMECLIDINIUM
    a) At the time of this review, no data were available to assess the teratogenic potential of this agent (Prod Info INCRUSE(TM) ELLIPTA(R) oral inhalation powder, 2014).
    B) LACK OF EFFECT
    1) DICYCLOMINE HYDROCHLORIDE
    a) Among 1690 pregnancies, the incidence of skeletal and limb malformations, cardiac defects, and oral cleft did not differ between infants exposed to dicyclomine and those who were not (Morelock et al, 1982). Congenital malformation rates also were similar among 1593 infants exposed to dicyclomine during the first trimester, even when controlling for confounding factors (Shapiro et al, 1977).
    C) ANIMAL STUDIES
    1) ACLIDINIUM BROMIDE
    a) RATS, RABBITS: Animal studies revealed no evidence of structural alterations in rats or rabbits administered aclidinium bromide at doses 15 and 20 times the recommended human daily dose (RHDD), respectively, during organogenesis (Prod Info TUDORZA(TM) PRESSAIR(TM) oral inhalation powder, 2012).
    2) CLIDINIUM BROMIDE
    a) RATS: In animal studies, no congenital anomalies or teratogenic effects were observed in rats administered oral doses of either 2.5 mg/kg chlordiazepoxide hydrochloride with 1.25 mg/kg clidinium bromide or 25 mg/kg chlordiazepoxide hydrochloride with 12.5 mg/kg clidinium bromide during 2 successive matings. A slight decrease in the number of pups surviving during lactation was observed in rats receiving the highest dose during the first mating. A slight decrease in the number of pregnant females as well as the number of pups surviving until weaning was observed during the second mating (Prod Info LIBRAX(R) oral capsules, 2009).
    b) RATS: In animal studies, there was no evidence of congenital anomalies in rats administered chlordiazepoxide hydrochloride 10, 20 or 80 mg/kg/day followed by breeding. In a similar study, rats administered chlordiazepoxide hydrochloride 100 mg/kg/day experienced a significant decrease in fertilization rate and decreased body weight and viability of offspring. Major skeletal defects were observed in 1 neonate from both the first and second mating receiving chlordiazepoxide hydrochloride 100 mg/kg/day. During 2 reproduction studies in rats administered clidinium bromide 2.5 and 10 mg/kg/day, respectively, there was no incidence of congenital anomalies or teratogenic effects (Prod Info LIBRAX(R) oral capsules, 2009).
    3) FESOTERODINE FUMARATE
    a) MICE, RABBITS: In mice and rabbit studies, no oral dose-related teratogenicity was observed at doses up to 75 mg/kg/day in mice, up to 27 mg/kg/day in rabbits, or at subcutaneous doses up to 4.5 mg/kg/day in rabbits. In mice treated with 75 mg/kg/day, increased resorptions and a decrease in live fetuses were observed. Cleft palate was observed in 1 fetus at doses of 15, 45, and 75 mg/kg/day. In rabbits, incomplete ossified sternebrae (retardation of bone development) was reported in rabbits treated with subcutaneous doses of 4.5 mg/kg/day. Oral doses of 30 mg/kg/day resulted in decreased body weight of the dams and delayed ear opening of the pups (Prod Info TOVIAZ(TM) extended-release oral tablets, 2008).
    4) GLYCOPYRROLATE
    a) No evidence of teratogenic effects was seen in animals when pregnant females were administered 18,000 and 270 times the maximum recommended human daily inhalation dose on a body surface area basis when delivered orally or via intramuscular injection, respectively (Prod Info BEVESPI AEROSPHERE(TM) inhalation aerosol powder, 2016).
    b) In animal studies, there were no reports of teratogenic effects (Prod Info glycopyrrolate oral tablets, 2015; Prod Info SEEBRI(TM) NEOHALER(R) oral inhalation powder, 2015) with glycopyrrolate doses up to 1400 times the maximum recommended human dose (MRHD). No effects on perinatal or postnatal development were reported in animals following administration of glycopyrrolate doses up to 1100 times the MRHD (Prod Info CUVPOSA(R) oral solution, 2015; Prod Info SEEBRI(TM) NEOHALER(R) oral inhalation powder, 2015).
    c) In animal studies, there were no teratogenic effects to the fetus at dietary or intramuscular doses up to 320 times the maximum recommended daily human dose of 2 mg on a mg/m(2) basis. Glycopyrrolate does not appear to affect fetal heart rate or fetal heart rate variability; however, dietary administration of glycopyrrolate resulted in decreased offspring survival in a dose related manner (Prod Info glycopyrrolate intravenous injection, 2014).
    5) GLYCOPYRROLATE/INDACATEROL
    a) During animal studies, no effects on perinatal or postnatal development were reported with indacaterol doses up to 110 times the maximum recommended human dose (MRHD) or with glycopyrrolate at doses up to 1100 times the MRHD. There were also no reports of teratogenicity with indacaterol at doses up to 770 times the MRHD or glycopyrrolate at doses up to 1400 times the MRHD (Prod Info UTIBRON(TM) NEOHALER(R) oral inhalation powder, 2015).
    6) GLYCOPYRRONIUM
    a) RATS, RABBITS: Following inhalation administration, glycopyrronium did not appear to have any teratogenic effects in rats or rabbits (Prod Info Enurev Breezhaler oral inhalation powder capsules, 2012).
    7) IPRATROPIUM BROMIDE
    a) MICE, RATS, RABBITS: Animal reproduction studies did not result in teratogenic effects in mice, rats, or rabbits given oral ipratropium bromide doses of 10, 1,000, and 125 mg/kg (approximately 160, 32,000, and 8,000 times the maximum recommended daily intranasal dose (MRDID) in adults on a mg/m(2) basis), respectively. In a similar inhalation reproduction study, rats and rabbits given ipratropium bromide doses of 1.5 and 1.8 mg/kg, respectively (approximately 50 and 120 times, respectively, the MRDID in adults on a mg/m(2) basis) showed no evidence of teratogenicity. Although rats treated with oral doses of ipratropium bromide 90 mg/kg (approximately 2,900 times the MRDID in adults on a mg/m(2) basis) and above resulted in embryotoxicity as resorption increased, this effect is not considered to be relevant to human use due to the difference in administration route as well as the large doses consumed (Prod Info Atrovent(R) nasal spray, 2011; Prod Info ipratropium bromide 0.02% inhalation solution, 2007).
    b) MICE, RATS, RABBITS: Animal reproduction studies did not result in teratogenic effects in mice, rats, or rabbits given oral ipratropium bromide doses approximately 200, 40,000, and 10,000 times the maximum recommended human daily inhalation dose (MRHDID) in adults on a mg/m(2) basis, respectively. Although rats treated with oral doses of ipratropium bromide approximately 3,600 times the MRHDID in adults on a mg/m(2) basis resulted in embryotoxicity as resorption increased, this effect is not considered to be relevant to human use due to the difference in administration route as well as the large doses consumed (Prod Info ATROVENT(R) HFA oral inhalation aerosol, 2010).
    8) OXYBUTYNIN
    a) MICE, RATS, HAMSTERS, RABBITS: Studies conducted in rodents (mice, rats, and hamsters) and rabbits have shown no evidence of teratogenic effects associated with the use of oxybutynin during pregnancy (Prod Info DITROPAN XL(R) oral extended release tablets, 2008; Prod Info DITROPAN(R) oral tablets, syrup, 2008; Prod Info OXYTROL(TM) transdermal patch, 2006). In 1 animal study, there was no evidence of harm to the fetus in rats and rabbits receiving subcutaneous oxybutynin doses up to 25 mg/kg (approximately 50 times the human exposure) and doses up to 0.4 mg/kg (approximately 1 time the human exposure), respectively (Prod Info GELNIQUE(R)10% topical gel, 2009).
    9) TIOTROPIUM BROMIDE
    a) In animal studies, there was no evidence of structural alterations at maternal tiotropium inhalation doses up to 790 and 8 times the recommended human daily dose on a mg/m(2) basis (Prod Info SPIRIVA(R) HANDIHALER(R) oral inhalation powder, 2015).
    10) TOLTERODINE TARTRATE
    a) MICE: There were no anomalies or malformations observed at maternal oral doses up to 14 times the human exposure (20 mg/kg/day) in mice. When pregnant mice were given oral doses 30 to 40 mg/kg/day, there was an increased incidence of fetal abnormalities including cleft palate, digital abnormalities, intraabdominal hemorrhage, and various skeletal abnormalities, primarily reduced ossification). At these doses, the AUC values were 20- to 25-fold higher compared with humans (Prod Info DETROL(R) oral tablets, 2008).
    b) RABBITS: There was no evidence of teratogenicity at maternal subcutaneous doses of 0.8 mg/kg/day in rabbits. This dose achieved an AUC of 100 mcg x hour/L which is 3-fold higher than that resulting from the human dose (Prod Info DETROL(R) oral tablets, 2008).
    11) UMECLIDINIUM
    a) RATS, RABBITS: No teratogenic effects were found in rats administered umeclidinium at maternal inhaled doses up to 278 mcg/kg/day and rabbits administered umeclidinium at maternal subQ does up to 180 mcg/kg/day (approximately 50 and 200 times, respectively, the maximum recommended human daily inhaled dose [MRHDID] in adults on a AUC basis. No effects on perinatal and postnatal development were observed in rats following maternal administration at subQ doses up to 180 mcg/kg/day (approximately 80 times the MRHDID in adults on an AUC basis) (Prod Info INCRUSE(TM) ELLIPTA(R) oral inhalation powder, 2014).
    12) UMECLIDINIUM/VILANTEROL
    a) LACK OF EFFECT: RATS: Administration in rats of the single agent umeclidinium at inhaled doses up to 278 mcg/kg/day (approximately 50 times the maximum recommended human daily inhalation dose (MRHDID) on an AUC basis) revealed no evidence of teratogenicity (Prod Info ANORO(TM) ELLIPTA(TM) oral inhalation powder, 2013).
    b) LACK OF EFFECT: RABBITS: Teratogenic effects were not observed in rabbits administered umeclidinium subQ maternal doses up to 180 mcg/kg/day (approximately 200 times the MRHDID on an AUC basis). However, in single agent studies of vilanterol, fetal skeletal variations, including decreased or absent ossification in cervical vertebral centrum and metacarpals, were observed in rabbits administered vilanterol at inhaled doses of 5740 mcg/kg/day or subQ doses of 300 mcg/kg/day (approximately 450 times the MRHDID in adults on an AUC basis) (Prod Info ANORO(TM) ELLIPTA(TM) oral inhalation powder, 2013).

    C) RISK SUMMARY
    1) GLYCOPYRROLATE/INDACATEROL
    a) Use during pregnancy only if the potential maternal benefit outweighs the potential fetal risk (Prod Info UTIBRON(TM) NEOHALER(R) oral inhalation powder, 2015).
    2) OLODATEROL/TIOTROPIUM BROMIDE
    a) Administer during pregnancy only if the benefit justifies the risk to the fetus (Prod Info STIOLTO(TM) RESPIMAT(R) oral inhalation spray, 2015).
    D) LABOR OR DELIVERY
    1) GLYCOPYRROLATE/FORMOTEROL FUMARATE
    a) No well-controlled trials have investigated the effects of glycopyrrolate/formoterol fumarate on labor. Since beta-2 agonists such as glycopyrrolate/formoterol fumarate can interfere with uterine contractions, the drug should be used during labor only if the potential benefits justify the potential risk (Prod Info BEVESPI AEROSPHERE(TM) inhalation aerosol powder, 2016).
    2) OLODATEROL/TIOTROPIUM BROMIDE
    a) Restrict use during labor to only those cases where the benefit clearly outweighs the risk (Prod Info STIOLTO(TM) RESPIMAT(R) oral inhalation spray, 2015).
    E) LACK OF EFFECT
    1) DICYCLOMINE HYDROCHLORIDE
    a) In epidemiologic studies of pregnant women with products containing dicyclomine (40 mg/day), an increased risk of fetal abnormalities has not been demonstrated during the first trimester. Studies using the recommended dose of 80 to 160 mg/day have not been performed (Prod Info BENTYL(R) oral capsules, oral tablets, oral syrup, intramuscular injection, 2011).
    b) No increased risk of birth defects associated with the use of dicyclomine was found in a meta-analysis and a prospective cohort study of pregnant women using dicyclomine during the first trimester (relative risk: 1.04; 95% confidence interval: 0.82-1.30) (Magee et al, 2002). No increased risk of fetal anomaly was observed in epidemiologic studies with dicyclomine (Eskenazi & Bracken, 1985; Aselton et al, 1984; McCredie et al, 1984; Mitchell et al, 1983; Morelock et al, 1982; Rothman et al, 1979; Shapiro et al, 1977).
    2) GLYCOPYRROLATE
    a) In single-dose studies in humans, very small amounts of glycopyrrolate crossed the placental barrier (Prod Info ROBINUL(R) Injection, 2005).
    F) ANIMAL STUDIES
    1) ACLIDINIUM BROMIDE
    a) RATS, RABBITS: Administration of aclidinium bromide 1400 and 2300 times the recommended human daily dose (RHDD) resulted in incidences of additional liver lobes and decreased fetal body weights, respectively, amongst Himalayan rabbits. Maternal toxicity was also reported amongst rats administered inhaled aclidinium bromide doses greater than or equal to 0.2 mg/kg/day (Prod Info TUDORZA(TM) PRESSAIR(TM) oral inhalation powder, 2012).
    2) DICYCLOMINE HYDROCHLORIDE
    a) RATS, RABBITS: In rats and rabbits, there was no evidence of impaired fertility or fetal harm at maternal doses up to 33 times the maximum recommended human dose based on 160 mg/day (3 mg/kg) (Prod Info BENTYL(R) oral capsules, oral tablets, oral syrup, intramuscular injection, 2011).
    3) GLYCOPYRROLATE
    a) No effects on perinatal or postnatal development were reported in animals following administration of glycopyrrolate doses at approximately 1100 times the maximum recommended human dose (Prod Info SEEBRI(TM) NEOHALER(R) oral inhalation powder, 2015).
    4) GLYCOPYRROLATE/INDACATEROL
    a) During animal studies, no effects on perinatal or postnatal development were reported with indacaterol doses up to 110 times the maximum recommended human dose (MRHD) or with glycopyrrolate at doses up to 1100 times the MRHD. There were also no reports of teratogenicity with indacaterol at doses up to 770 times the MRHD or glycopyrrolate at doses up to 1400 times the MRHD (Prod Info UTIBRON(TM) NEOHALER(R) oral inhalation powder, 2015).
    5) MEPENZOLATE BROMIDE
    a) RATS, RABBITS: In rats and rabbits, no evidence of impaired fertility or harm to the fetus has been shown at maternal doses up to 30 times the human dose based on a 50 kg weight (Prod Info CANTIL(R) oral tablet, 2003).
    6) TIOTROPIUM BROMIDE
    a) Fetal resorption, litter loss, decreases in number of live pups at birth and mean pup weights, and delayed pup sexual maturation were reported at maternal tiotropium inhalation doses 45 times the recommended human daily dose (RHDD). These effects were not noted at inhalation doses 4 and 80 times the RHDD, while postimplantation loss was observed at an inhalation dose approximately 360 times the RHDD based on mg/m(2) (Prod Info SPIRIVA(R) RESPIMAT(R) oral inhalation spray, 2014).
    7) TOLTERODINE TARTRATE
    a) MICE: Maternal oral doses 30 to 40 mg/kg/day were shown to be embryolethal and reduce fetal weight in mice. At these doses, the AUC values were 20- to 25-fold higher compared with humans (Prod Info DETROL(R) oral tablets, 2008).
    b) RABBITS: There was no evidence of embryotoxicity at maternal subcutaneous doses of 0.8 mg/kg/day in rabbits. This dose achieved an AUC of 100 mcg x hour/L which is 3-fold higher than that resulting from the human dose (Prod Info DETROL(R) oral tablets, 2008).
    8) UMECLIDINIUM
    a) RATS: There were no observed effects on peri- or postnatal development in rats administered umeclidinium at subQ doses up to 180 mcg/kg/day (approximately 80 times the maximum recommended human daily inhalation dose (MRHDID) in adults) (Prod Info INCRUSE(TM) ELLIPTA(R) oral inhalation powder, 2014; Prod Info ANORO(TM) ELLIPTA(TM) oral inhalation powder, 2013).
    3.20.4) EFFECTS DURING BREAST-FEEDING
    A) LACK OF INFORMATION
    1) GLYCOPYRROLATE

However, the highly polar quaternary ammonium group of glycopyrrolate limits its passage across lipid membranes (Prod Info CUVPOSA oral solution, 2010; Prod Info Glycopyrrolate intramuscular injection, intravenous injection, 2009)
    b) Discontinue treatment or discontinue nursing taking into account the importance of the drug to the mother (Prod Info glycopyrrolate oral tablets, 2015; Prod Info SEEBRI(TM) NEOHALER(R) oral inhalation powder, 2015).
    2) GLYCOPYRROLATE/FORMOTEROL FUMARATE
    1) It is not known whether glycopyrrolate/formoterol fumarate is excreted in human milk, although it has been detected in the milk of lactating rats. Therefore, caution should be exercised when glycopyrrolate/formoterol fumarate is administered to lactating women (Prod Info BEVESPI AEROSPHERE(TM) inhalation aerosol powder, 2016).

    C) BREAST MILK
    1) ACLIDINIUM BROMIDE
    a) Lactation studies with aclidinium bromide have not been conducted and the effects, if any, on a breastfeeding infant are unknown. Animal studies have shown that aclidinium bromide is excreted in the milk of lactating rats and has resulted in decreased pup weight. Because many drugs are excreted into human milk, the manufacturer recommends using caution when administering aclidinium bromide to a lactating woman (Prod Info TUDORZA(TM) PRESSAIR(TM) oral inhalation powder, 2012).
    2) DICYCLOMINE
    a) Dicyclomine has been shown to be excreted in human milk and is contraindicated in nursing mothers (Prod Info BENTYL(R) oral capsules, oral tablets, oral syrup, intramuscular injection, 2011).
    3) GLYCOPYRROLATE
    a) It is unknown whether glycopyrrolate is excreted into human breast milk. Discontinue nursing or discontinue glycopyrrolate, taking into account the importance of the drug to the mother (Prod Info SEEBRI(TM) NEOHALER(R) oral inhalation powder, 2015).
    4) GLYCOPYRROLATE/FORMOTEROL FUMARATE
    a) It is not known whether glycopyrrolate/formoterol fumarate is excreted in human milk, although it has been detected in the milk of lactating rats. Therefore, caution should be exercised when glycopyrrolate/formoterol fumarate is administered to lactating women (Prod Info BEVESPI AEROSPHERE(TM) inhalation aerosol powder, 2016).
    5) GLYCOPYRROLATE/INDACATEROL
    a) It is unknown whether glycopyrrolate/indacaterol or the individual components are excreted into human breast milk. Discontinue treatment or discontinue nursing, taking into account the importance of the drug to the mother (Prod Info UTIBRON(TM) NEOHALER(R) oral inhalation powder, 2015).

    E) ANIMAL STUDIES
    1) ACLIDINIUM BROMIDE
    a) RATS: Aclidinium bromide lactation studies have not yet been conducted in humans. In animal studies, administration of aclidinium bromide approximately 5 times the recommended human daily dose to rats during the lactation period resulted in decreased pup weight (Prod Info TUDORZA(TM) PRESSAIR(TM) oral inhalation powder, 2012).
    2) GLYCOPYRROLATE
    a) Glycopyrrolate has been detected in the milk of lactating animals with concentrations reaching up to 10-fold higher in the milk than that of the mother (Prod Info SEEBRI(TM) NEOHALER(R) oral inhalation powder, 2015).

    7) TOLTERODINE TARTRATE
    a) MICE: Immediate-release tolterodine is excreted into the milk of lactating mice. Offspring of female mice treated with tolterodine 20 mg/kg/day during the lactation period had slightly reduced body weight gain. However, the weight was regained during the maturation phase (Prod Info DETROL(R) oral tablets, 2008).
    8) UMECLIDINIUM
    a) RATS: In a rat study, subQ administration of umeclidinium at approximately 25 times the maximum recommended human inhaled daily dose in adults resulted in a measurable amount of umeclidinium in 2 nursing pups, which may indicate transfer of umeclidinium in milk (Prod Info INCRUSE(TM) ELLIPTA(R) oral inhalation powder, 2014; Prod Info ANORO(TM) ELLIPTA(TM) oral inhalation powder, 2013).

    B) ANIMAL STUDIES
    1) DECREASED FERTILITY
    a) ATROPINE/PRALIDOXIME CHLORIDE
    1) RATS: A dose-related decrease in fertility was observed in male rats administered atropine up to 125 mg/kg one week prior to mating and throughout the 5-day mating period. No studies have been performed with pralidoxime (Prod Info DuoDote(R) intramuscular injection solution, 2011).
    b) ACLIDINIUM BROMIDE
    1) RATS: Both fertility and reproductive performance indices were impaired in male and female rats administered inhaled aclidinium bromide at doses greater than or equal to 0.8 mg/kg/day (approximately 15 times the recommended human daily dose (RHDD)). Paternal toxicity evidenced by mortality and decreased body weight gain was also observed. Mating index, sperm count, and morphology were not effected. A separate fertility assessment revealed no effect on male and female rats administered inhaled doses of 1.9 and 0.8 mg/kg/day, respectively (approximately 30 and 15 times the RHDD, respectively) (Prod Info TUDORZA(TM) PRESSAIR(TM) oral inhalation powder, 2012).
    c) GLYCOPYRROLATE
    1) Fertility was impaired (eg, decreased corpora lutea, decreased implantation sties, decreased live fetuses) in male and female animals administered subQ glycopyrrolate at doses up to 1900 times the maximum recommended human dose (MRHD). There were no adverse effects on fertility or reproductive performance with doses approximately 350 times the MRHD (Prod Info SEEBRI(TM) NEOHALER(R) oral inhalation powder, 2015).
    2) RATS, DOGS: In rat studies, dietary administration of glycopyrrolate led to diminished rates of conception in a dose-related manner. In dog studies, diminished seminal secretion was evident at high doses of glycopyrrolate; it is possible that diminished seminal secretion may cause the decreased conception rates (Prod Info ROBINUL(R) Injection, 2005).
    d) GLYCOPYRROLATE/INDACATEROL
    1) Fertility was impaired (eg, decreased corpora lutea, decreased implantation sties, decreased live fetuses) in male and female animals administered subQ glycopyrrolate at doses up to 1900 times the maximum recommended human dose (MRHD). There were no adverse effects on fertility or reproductive performance with doses approximately 350 times the MRHD (Prod Info UTIBRON(TM) NEOHALER(R) oral inhalation powder, 2015).
    e) IPRATROPIUM BROMIDE
    1) RATS: In male and female fertility studies, an oral dose of 500 mg/kg (approximately 16,000 times the maximum recommended daily intranasal dose in adults on a mg/m2 basis), ipratropium bromide decreased in the conception rate (Prod Info Atrovent(R) nasal spray, 2011).
    f) TIOTROPIUM BROMIDE
    1) In animal studies, tiotropium inhalation doses approximately 40 times the recommended human daily dose (RHDD) on a mg/m(2) basis resulted in decreased numbers of corpora lutea and percentages of implants. At a dose approximately 5 times the RHDD, no such effects were reported. Inhalation doses up to approximately 910 times the RHDD, however, did not affect the fertility index (Prod Info SPIRIVA(R) HANDIHALER(R) oral inhalation powder, 2015).
    2) LACK OF EFFECT
    a) DICYCLOMINE
    1) RATS: In rat studies, dicyclomine at doses up to 100 mg/kg/day did not result in any adverse effects on breeding, conception, or parturition (Prod Info BENTYL(R) oral capsules, oral tablets, oral syrup, intramuscular injection, 2011).
    b) GLYCOPYRROLATE
    1) No evidence of teratogenic effects was seen in animals when pregnant females were administered 18,000 and 270 times the maximum recommended human daily inhalation dose on a body surface area basis when delivered orally or via intramuscular injection, respectively (Prod Info BEVESPI AEROSPHERE(TM) inhalation aerosol powder, 2016).
    c) GLYCOPYRROLATE
    1) RATS: Fertility or reproductive parameters were not affected in rats who received the equivalent of 50 times the maximum recommended human dose of glycopyrrolate in a clinical study (Prod Info CUVPOSA(R) oral solution, 2013).
    d) GLYCOPYRRONIUM
    1) RATS: Fertility was not affected in rats following inhalation administration of glycopyrronium (Prod Info Enurev Breezhaler oral inhalation powder capsules, 2012).
    e) OXYBUTYNIN
    1) MICE, RATS, HAMSTERS, RABBITS: In reproduction studies in mice, rats, hamsters, and rabbits, there was no definite evidence of impaired fertility (Prod Info GELNIQUE(R)10% topical gel, 2009; Prod Info DITROPAN XL(R) oral extended release tablets, 2008; Prod Info DITROPAN(R) oral tablets, syrup, 2008; Prod Info OXYTROL(TM) transdermal patch, 2006).
    f) TOLTERODINE TARTRATE
    1) MICE: In female mice treated with 20 mg/kg a day for 2 weeks before mating (a systemic exposure 15-fold higher in animals than in humans based on an AUC value of 500 mcg x hr/L), no effects on fertility or on reproductive performance were observed. In male mice, a dose of 30 mg/kg/day did not induce any adverse effects on fertility (Prod Info DETROL(R) oral tablets, 2008).
    g) UMECLIDINIUM
    1) RATS: No fertility studies were conducted with the umeclidinium and vilanterol combination; however, in reproductive studies in male and female rats, no evidence of impaired fertility was observed with subQ administration of single-agent umeclidinium at doses up to 180 mcg/kg/day and inhaled doses up to 294 mcg/kg/day (approximately 100 and 50 times, respectively, the maximum recommended human daily inhaled dose [MRHDID] in adults on an AUC basis) (Prod Info INCRUSE(TM) ELLIPTA(R) oral inhalation powder, 2014; Prod Info ANORO(TM) ELLIPTA(TM) oral inhalation powder, 2013).

In a 24-month carcinogenicity study in Sprague-Dawley rats, an increased incidence of mesovarian leiomyoma and uterine leiomyosarcoma were reported with inhaled doses of formoterol fumarate 130 mcg/kg (approximately 65 times the MRHDID on a mcg/m(2) basis) (Prod Info BEVESPI AEROSPHERE(TM) inhalation aerosol powder, 2016).

Genotoxicity

    A) INDACATEROL/GLYCOPYRROLATE
    1) There was no evidence of genotoxicity or mutagenicity with glycopyrrolate in the following tests: In vitro Ames test, in vitro human lymphocyte chromosomal aberration assay, and in vivo rat bone marrow micronucleus assay (Prod Info UTIBRON(TM) NEOHALER(R) oral inhalation powder, 2015).

    1) There was no evidence of genotoxicity or mutagenicity with glycopyrrolate in the following tests: bacterial reverse mutation assay, in vitro mammalian cell micronucleus assay in TK6 cells, or the in vivo micronucleus assay in rats. There was no evidence of genotoxicity or mutagenicity with formoterol fumarate in the following tests: Ames Salmonella/microsome plate test, mouse lymphoma test, chromosome aberration test in human lymphocytes, and rat micronucleus test (Prod Info BEVESPI AEROSPHERE(TM) inhalation aerosol powder, 2016).

Monitoring Parameters Levels

    4.1.1) SUMMARY
    A) Monitor vital signs (including temperature) and mental status.
    B) No specific lab work is needed in most patients.
    C) Monitor creatinine phosphokinase in patients with prolonged agitation, seizures, or coma.
    D) Monitor renal function and urine output in patients with rhabdomyolysis.

    4.1.2) SERUM/BLOOD
    A) BLOOD/SERUM CHEMISTRY
    1) Monitor serum electrolytes, renal function and CPK levels in patients with prolonged agitation or coma.
    2) Serum levels of anticholinergic drugs are not clinically useful.
    4.1.3) URINE
    A) URINALYSIS

    4.1.4) OTHER
    A) OTHER
    1) MONITORING
    a) Institute continuous cardiac monitoring and follow ECG in patients with persistent tachycardia, hemodynamic instability, seizures or severe mental status changes.

Methods

    A) MULTIPLE ANALYTICAL METHODS
    1) Anticholinergics may be detected with specific examinations of urine or blood, although with occasional difficulty due to low concentration.
    2) ATROPINE - A sensitive radioreceptor assay was developed to detect small concentrations of atropine in the plasma (Metcalfe, 1980).
    a) This particular assay is sensitive to concentrations of atropine as low as 0.9 ng/ml of plasma.
    3) SCOPOLAMINE - A radioligand binding assay was developed to determine the very low urinary concentrations of scopolamine that are found after transdermal administration of the drug (Scheurlen et al, 1984).
    a) This particular assay is sensitive to concentrations of scopolamine as low as 1.2 ng/ml of urine.
    b) This assay method is limited to detecting only urinary concentrations of transdermal scopolamine. The transdermal system only supplies 0.5 mcg of scopolamine per hour to the blood, which is too small of an amount to be detected by this method (Scheurlen et al, 1984).
    B) CHROMATOGRAPHY
    1) Gas chromatography-mass spectrometry was used to identify the presence of scopolamine in the urine of patients who were heroin users and were exhibiting signs and symptoms of anticholinergic toxicity (Perrone et al, 1999).

Life Support

    A) Support respiratory and cardiovascular function.

Patient Disposition

    6.3.1) DISPOSITION/ORAL EXPOSURE
    6.3.1.1) ADMISSION CRITERIA/ORAL
    A) Patients with significant persistent central nervous system toxicity (i.e., hallucinations, somnolence, delirium, coma), or persistent tachycardia should be admitted. Patients with coma, seizures or delirium should be admitted to an intensive care setting.
    6.3.1.2) HOME CRITERIA/ORAL
    A) Asymptomatic children (other than mild drowsiness or stimulation) with acute inadvertent ingestion may be monitored at home.
    6.3.1.3) CONSULT CRITERIA/ORAL
    A) Consult a poison center or medical toxicologist for assistance in managing patients with severe toxicity (i.e., seizures, severe delirium, coma), or in whom the diagnosis is not clear.
    6.3.1.5) OBSERVATION CRITERIA/ORAL
    A) Patients with deliberate ingestions and symptomatic patients should be sent to a health care facility for observation for 6 to 8 hours.
    B) SCOPOLAMINE - In 115 patients with acute poisoning from over-the-counter sleeping preparations, including scopolamine preparations (Sominex(R) and Sleepeze(R)), the least amount of scopolamine ingested to produce life-threatening symptoms was 2 to 4 mg. Patients reporting ingestions greater than 2 mg of scopolamine should be observed for at least 6 hours prior to discharge from medical care. If an accurate history is unobtainable, all patients should be observed for at least 4 to 6 hours for signs and symptoms of anticholinergic toxicity (Hooper et al, 1979).

Monitoring

    A) Monitor vital signs (including temperature) and mental status.
    B) No specific lab work is needed in most patients.
    C) Monitor creatinine phosphokinase in patients with prolonged agitation, seizures, or coma.
    D) Monitor renal function and urine output in patients with rhabdomyolysis.
    E) Obtain an ECG and institute continuous cardiac monitoring in patients with moderate to severe toxicity (i.e., agitation, delirium, seizures, coma and hypotension).

Oral Exposure

    6.5.1) PREVENTION OF ABSORPTION/PREHOSPITAL
    A) ACTIVATED CHARCOAL
    1) PREHOSPITAL ACTIVATED CHARCOAL ADMINISTRATION
    a) Consider prehospital administration of activated charcoal as an aqueous slurry in patients with a potentially toxic ingestion who are awake and able to protect their airway. Activated charcoal is most effective when administered within one hour of ingestion. Administration in the prehospital setting has the potential to significantly decrease the time from toxin ingestion to activated charcoal administration, although it has not been shown to affect outcome (Alaspaa et al, 2005; Thakore & Murphy, 2002; Spiller & Rogers, 2002).
    1) In patients who are at risk for the abrupt onset of seizures or mental status depression, activated charcoal should not be administered in the prehospital setting, due to the risk of aspiration in the event of spontaneous emesis.
    2) The addition of flavoring agents (cola drinks, chocolate milk, cherry syrup) to activated charcoal improves the palatability for children and may facilitate successful administration (Guenther Skokan et al, 2001; Dagnone et al, 2002).
    2) CHARCOAL DOSE
    a) Use a minimum of 240 milliliters of water per 30 grams charcoal (FDA, 1985). Optimum dose not established; usual dose is 25 to 100 grams in adults and adolescents; 25 to 50 grams in children aged 1 to 12 years (or 0.5 to 1 gram/kilogram body weight) ; and 0.5 to 1 gram/kilogram in infants up to 1 year old (Chyka et al, 2005).
    1) Routine use of a cathartic with activated charcoal is NOT recommended as there is no evidence that cathartics reduce drug absorption and cathartics are known to cause adverse effects such as nausea, vomiting, abdominal cramps, electrolyte imbalances and occasionally hypotension (None Listed, 2004).
    b) ADVERSE EFFECTS/CONTRAINDICATIONS
    1) Complications: emesis, aspiration (Chyka et al, 2005). Aspiration may be complicated by acute respiratory failure, ARDS, bronchiolitis obliterans or chronic lung disease (Golej et al, 2001; Graff et al, 2002; Pollack et al, 1981; Harris & Filandrinos, 1993; Elliot et al, 1989; Rau et al, 1988; Golej et al, 2001; Graff et al, 2002). Refer to the ACTIVATED CHARCOAL/TREATMENT management for further information.
    2) Contraindications: unprotected airway (increases risk/severity of aspiration) , nonfunctioning gastrointestinal tract, uncontrolled vomiting, and ingestion of most hydrocarbons (Chyka et al, 2005).
    6.5.2) PREVENTION OF ABSORPTION
    A) SUMMARY
    1) Anticholinergics slow GI motility; sustained-release preparations are available. Gastric decontamination may be worthwhile even if delayed (Tenenbein et al, 2001). Activated charcoal is generally sufficient.
    B) ACTIVATED CHARCOAL
    1) CHARCOAL ADMINISTRATION
    a) Consider administration of activated charcoal after a potentially toxic ingestion (Chyka et al, 2005). Administer charcoal as an aqueous slurry; most effective when administered within one hour of ingestion.
    2) CHARCOAL DOSE
    a) Use a minimum of 240 milliliters of water per 30 grams charcoal (FDA, 1985). Optimum dose not established; usual dose is 25 to 100 grams in adults and adolescents; 25 to 50 grams in children aged 1 to 12 years (or 0.5 to 1 gram/kilogram body weight) ; and 0.5 to 1 gram/kilogram in infants up to 1 year old (Chyka et al, 2005).
    1) Routine use of a cathartic with activated charcoal is NOT recommended as there is no evidence that cathartics reduce drug absorption and cathartics are known to cause adverse effects such as nausea, vomiting, abdominal cramps, electrolyte imbalances and occasionally hypotension (None Listed, 2004).
    b) ADVERSE EFFECTS/CONTRAINDICATIONS
    1) Complications: emesis, aspiration (Chyka et al, 2005). Aspiration may be complicated by acute respiratory failure, ARDS, bronchiolitis obliterans or chronic lung disease (Golej et al, 2001; Graff et al, 2002; Pollack et al, 1981; Harris & Filandrinos, 1993; Elliot et al, 1989; Rau et al, 1988; Golej et al, 2001; Graff et al, 2002). Refer to the ACTIVATED CHARCOAL/TREATMENT management for further information.
    2) Contraindications: unprotected airway (increases risk/severity of aspiration) , nonfunctioning gastrointestinal tract, uncontrolled vomiting, and ingestion of most hydrocarbons (Chyka et al, 2005).
    3) One study concluded that activated charcoal is more effective in the presence of anticholinergic activity because of the delayed gastric emptying effects which provide a greater window for drug adsorption to activated charcoal (Green et al, 2004). Therefore, consider administering activated charcoal up to a few hours post-ingestion if the patient is protecting airway and experiencing anticholinergic effects.
    6.5.3) TREATMENT
    A) PHYSOSTIGMINE
    1) SUMMARY
    a) A diagnostic trial with physostigmine (see physostigmine dosing below) may be initiated without waiting for laboratory confirmation. Reversal within minutes of coma, arrhythmias, hallucinations, and other findings can be expected if the diagnosis is correct and the patient has not suffered anoxia or other insult or ingested a combination preparation. Avoid in cases where tricyclic antidepressants may also be involved, or in patients with cardiac conduction defects suggestive of tricyclic antidepressant overdose (QRS widening).
    2) PHYSOSTIGMINE/INDICATIONS
    a) Physostigmine is indicated to reverse the CNS effects caused by clinical or toxic dosages of agents capable of producing anticholinergic syndrome; however, long lasting reversal of anticholinergic signs and symptoms is generally not achieved because of the relatively short duration of action of physostigmine (45 to 60 minutes) (Prod Info physostigmine salicylate intravenous injection, intramuscular injection, 2008). It is most often used diagnostically to distinguish anticholinergic delirium from other causes of altered mental status (Frascogna, 2007; Shannon, 1998).
    b) Physostigmine should not be used in patients with suspected tricyclic antidepressant overdose, or an ECG suggestive of tricyclic antidepressant overdose (eg, QRS widening). In the setting of tricyclic antidepressant overdose, use of physostigmine has precipitated seizures and intractable cardiac arrest (Stewart, 1979; Newton, 1975; Pentel & Peterson, 1980; Frascogna, 2007).
    3) DOSE
    a) ADULT: BOLUS: 2 mg IV at slow controlled rate, no more than 1 mg/min. May repeat doses at intervals of 10 to 30 min, if severe symptoms recur (Prod Info physostigmine salicylate intravenous injection, intramuscular injection, 2008). INFUSION: For patients with prolonged anticholinergic delirium, a continuous infusion of physostigmine may be considered. Starting dose is 2 mg/hr, titrate to effect (Eyer et al, 2008)
    b) CHILD: 0.02 mg/kg by slow IV injection, at a rate no more than 0.5 mg/minute. Repeat dosage at 5 to 10 minute intervals as long as the toxic effect persists and there is no sign of cholinergic effects. MAXIMUM DOSAGE: 2 mg total (Prod Info physostigmine salicylate intravenous injection, intramuscular injection, 2008).
    c) AVAILABILITY: Physostigmine salicylate is available in 2 mL ampules, each mL containing 1 mg of physostigmine salicylate in a vehicle containing sodium metabisulfite 0.1%, benzyl alcohol 2%, and water (Prod Info physostigmine salicylate intravenous injection, intramuscular injection, 2008).
    4) CAUTIONS
    a) Relative contraindications to the use of physostigmine are asthma, gangrene, diabetes, cardiovascular disease, intestinal or urogenital tract mechanical obstruction, peripheral vascular disease, cardiac conduction defects, atrioventricular block, and in patients receiving choline esters and depolarizing neuromuscular blocking agents (decamethonium, succinylcholine). It may cause anaphylactic symptoms and life-threatening or less severe asthmatic episodes in patients with sulfite sensitivity (Prod Info physostigmine salicylate intravenous injection, intramuscular injection, 2008).
    b) Too rapid IV administration of physostigmine has resulted in bradycardia, hypersalivation leading to respiratory difficulties, and possible seizures (Prod Info physostigmine salicylate intravenous injection, intramuscular injection, 2008).
    5) ATROPINE FOR PHYSOSTIGMINE TOXICITY
    a) Atropine should be available to reverse life-threatening physostigmine-induced, toxic cholinergic effects (Prod Info physostigmine salicylate intravenous injection, intramuscular injection, 2008; Frascogna, 2007). Atropine may be given at half the dose of previously given physostigmine dose (Daunderer, 1980).
    6) CLINICAL STUDY
    a) A retrospective study was conducted to compare the efficacy and safety of physostigmine with benzodiazepines for treatment of agitation and delirium associated with anticholinergic poisoning. Physostigmine controlled agitation and reversed delirium in 96% and 87% of the patients (n=45), respectively, as compared with benzodiazepine-controlled agitation in 24% of the patients (n=26). Benzodiazepines were completely ineffective in reversing delirium.
    1) There was a lower incidence of complications and a shorter time to recovery in those patients treated with physostigmine (7% and 12 hours, respectively) as compared with those patients treated with benzodiazepines (46% and 24 hours, respectively) (Burns et al, 2000).
    B) TACHYARRHYTHMIA
    1) Sinus tachydysrhythmias do NOT need to be routinely treated unless the patient demonstrates signs/symptoms of hemodynamic instability. Sedating agitated patients with benzodiazepines may diminish tachycardia. Severe tachydysrhythmias may respond to physostigmine or IV beta-blockers (short-acting titratable agents preferred).
    C) VENTRICULAR ARRHYTHMIA
    1) QRS widening or ventricular tachycardia may respond to sodium bicarbonate. A reasonable starting dose is 1 to 2 mEq/kg IV bolus. Repeat as needed; endpoints include cessation of dysrhythmias, normalization of QRS complexes and a blood pH of 7.45 to 7.55. Monitor ECG continuously and monitor serum electrolytes and venous blood gases.
    2) Consider lidocaine if sodium bicarbonate is not successful.
    3) LIDOCAINE/DOSE
    a) ADULT: 1 to 1.5 milligrams/kilogram via intravenous push. For refractory VT/VF an additional bolus of 0.5 to 0.75 milligram/kilogram can be given at 5 to 10 minute intervals to a maximum dose of 3 milligrams/kilogram (Neumar et al, 2010). Only bolus therapy is recommended during cardiac arrest.
    1) Once circulation has been restored begin a maintenance infusion of 1 to 4 milligrams per minute. If dysrhythmias recur during infusion repeat 0.5 milligram/kilogram bolus and increase the infusion rate incrementally (maximal infusion rate is 4 milligrams/minute) (Neumar et al, 2010).
    b) CHILD: 1 milligram/kilogram initial bolus IV/IO; followed by a continuous infusion of 20 to 50 micrograms/kilogram/minute (de Caen et al, 2015).
    4) LIDOCAINE/MAJOR ADVERSE REACTIONS
    a) Paresthesias; muscle twitching; confusion; slurred speech; seizures; respiratory depression or arrest; bradycardia; coma. May cause significant AV block or worsen pre-existing block. Prophylactic pacemaker may be required in the face of bifascicular, second degree, or third degree heart block (Prod Info Lidocaine HCl intravenous injection solution, 2006; Neumar et al, 2010).
    5) LIDOCAINE/MONITORING PARAMETERS
    a) Monitor ECG continuously; plasma concentrations as indicated (Prod Info Lidocaine HCl intravenous injection solution, 2006).
    6) Severe dysrhythmias may respond to physostigmine.
    D) CARDIOGENIC SHOCK
    1) Cardiogenic shock rarely occurs; however, in one case use of an intraaortic balloon pump was required (Freedberg et al, 1987).
    E) BETHANECHOL
    1) Bethanechol has been described as an adjunctive agent for treatment of peripheral anticholinergic side effects of drugs (Boyson, 1988). It is an agonist at muscarinic receptors and does not cross the blood-brain barrier.
    2) CASE REPORT (ADULT) - A 34-year-old female required treatment with trihexyphenidyl for dystonia. The dry mouth side effect was an undesirable effect because of a history of parotid abscess. Bethanechol 5 to 10 milligrams orally three times daily allowed dosage with trihexyphenidyl up to 40 milligrams daily with 95% improvement of the patient's symptoms (Boyson, 1988).
    F) SEIZURE
    1) SUMMARY
    a) Attempt initial control with a benzodiazepine (eg, diazepam, lorazepam). If seizures persist or recur, administer phenobarbital or propofol.
    b) Monitor for respiratory depression, hypotension, and dysrhythmias. Endotracheal intubation should be performed in patients with persistent seizures.
    c) Evaluate for hypoxia, electrolyte disturbances, and hypoglycemia (or, if immediate bedside glucose testing is not available, treat with intravenous dextrose).
    2) DIAZEPAM
    a) ADULT DOSE: Initially 5 to 10 mg IV, OR 0.15 mg/kg IV up to 10 mg per dose up to a rate of 5 mg/minute; may be repeated every 5 to 20 minutes as needed (Brophy et al, 2012; Prod Info diazepam IM, IV injection, 2008; Manno, 2003).
    b) PEDIATRIC DOSE: 0.1 to 0.5 mg/kg IV over 2 to 5 minutes; up to a maximum of 10 mg/dose. May repeat dose every 5 to 10 minutes as needed (Loddenkemper & Goodkin, 2011; Hegenbarth & American Academy of Pediatrics Committee on Drugs, 2008).
    c) Monitor for hypotension, respiratory depression, and the need for endotracheal intubation. Consider a second agent if seizures persist or recur after repeated doses of diazepam .
    3) NO INTRAVENOUS ACCESS
    a) DIAZEPAM may be given rectally or intramuscularly (Manno, 2003). RECTAL DOSE: CHILD: Greater than 12 years: 0.2 mg/kg; 6 to 11 years: 0.3 mg/kg; 2 to 5 years: 0.5 mg/kg (Brophy et al, 2012).
    b) MIDAZOLAM has been used intramuscularly and intranasally, particularly in children when intravenous access has not been established. ADULT DOSE: 0.2 mg/kg IM, up to a maximum dose of 10 mg (Brophy et al, 2012). PEDIATRIC DOSE: INTRAMUSCULAR: 0.2 mg/kg IM, up to a maximum dose of 7 mg (Chamberlain et al, 1997) OR 10 mg IM (weight greater than 40 kg); 5 mg IM (weight 13 to 40 kg); INTRANASAL: 0.2 to 0.5 mg/kg up to a maximum of 10 mg/dose (Loddenkemper & Goodkin, 2011; Brophy et al, 2012). BUCCAL midazolam, 10 mg, has been used in adolescents and older children (5-years-old or more) to control seizures when intravenous access was not established (Scott et al, 1999).
    4) LORAZEPAM
    a) MAXIMUM RATE: The rate of intravenous administration of lorazepam should not exceed 2 mg/min (Brophy et al, 2012; Prod Info lorazepam IM, IV injection, 2008).
    b) ADULT DOSE: 2 to 4 mg IV initially; repeat every 5 to 10 minutes as needed, if seizures persist (Manno, 2003; Brophy et al, 2012).
    c) PEDIATRIC DOSE: 0.05 to 0.1 mg/kg IV over 2 to 5 minutes, up to a maximum of 4 mg/dose; may repeat in 5 to 15 minutes as needed, if seizures continue (Brophy et al, 2012; Loddenkemper & Goodkin, 2011; Hegenbarth & American Academy of Pediatrics Committee on Drugs, 2008; Sreenath et al, 2010; Chin et al, 2008).
    5) PHENOBARBITAL
    a) ADULT LOADING DOSE: 20 mg/kg IV at an infusion rate of 50 to 100 mg/minute IV. An additional 5 to 10 mg/kg dose may be given 10 minutes after loading infusion if seizures persist or recur (Brophy et al, 2012).
    b) Patients receiving high doses will require endotracheal intubation and may require vasopressor support (Brophy et al, 2012).
    c) PEDIATRIC LOADING DOSE: 20 mg/kg may be given as single or divided application (2 mg/kg/minute in children weighing less than 40 kg up to 100 mg/min in children weighing greater than 40 kg). A plasma concentration of about 20 mg/L will be achieved by this dose (Loddenkemper & Goodkin, 2011).
    d) REPEAT PEDIATRIC DOSE: Repeat doses of 5 to 20 mg/kg may be given every 15 to 20 minutes if seizures persist, with cardiorespiratory monitoring (Loddenkemper & Goodkin, 2011).
    e) MONITOR: For hypotension, respiratory depression, and the need for endotracheal intubation (Loddenkemper & Goodkin, 2011; Manno, 2003).
    f) SERUM CONCENTRATION MONITORING: Monitor serum concentrations over the next 12 to 24 hours. Therapeutic serum concentrations of phenobarbital range from 10 to 40 mcg/mL, although the optimal plasma concentration for some individuals may vary outside this range (Hvidberg & Dam, 1976; Choonara & Rane, 1990; AMA Department of Drugs, 1992).
    6) OTHER AGENTS
    a) If seizures persist after phenobarbital, propofol or pentobarbital infusion, or neuromuscular paralysis with general anesthesia (isoflurane) and continuous EEG monitoring should be considered (Manno, 2003). Other anticonvulsants can be considered (eg, valproate sodium, levetiracetam, lacosamide, topiramate) if seizures persist or recur; however, there is very little data regarding their use in toxin induced seizures, controlled trials are not available to define the optimal dosage ranges for these agents in status epilepticus (Brophy et al, 2012):
    1) VALPROATE SODIUM: ADULT DOSE: An initial dose of 20 to 40 mg/kg IV, at a rate of 3 to 6 mg/kg/minute; may give an additional dose of 20 mg/kg 10 minutes after loading infusion. PEDIATRIC DOSE: 1.5 to 3 mg/kg/minute (Brophy et al, 2012).
    2) LEVETIRACETAM: ADULT DOSE: 1000 to 3000 mg IV, at a rate of 2 to 5 mg/kg/min IV. PEDIATRIC DOSE: 20 to 60 mg/kg IV (Brophy et al, 2012; Loddenkemper & Goodkin, 2011).
    3) LACOSAMIDE: ADULT DOSE: 200 to 400 mg IV; 200 mg IV over 15 minutes (Brophy et al, 2012). PEDIATRIC DOSE: In one study, median starting doses of 1.3 mg/kg/day and maintenance doses of 4.7 mg/kg/day were used in children 8 years and older (Loddenkemper & Goodkin, 2011).
    4) TOPIRAMATE: ADULT DOSE: 200 to 400 mg nasogastric/orally OR 300 to 1600 mg/day orally divided in 2 to 4 times daily (Brophy et al, 2012).
    G) PSYCHOMOTOR AGITATION
    1) INDICATION
    a) If patient is severely agitated, sedate with IV benzodiazepines.
    2) DIAZEPAM DOSE
    a) ADULT: 5 to 10 mg IV initially, repeat every 5 to 20 minutes as needed (Brophy et al, 2012; Prod Info diazepam IM, IV injection, 2008; Manno, 2003).
    b) CHILD: 0.1 to 0.5 mg/kg IV over 2 to 5 minutes; up to a maximum of 10 mg/dose. May repeat dose every 5 to 10 minutes as needed (Loddenkemper & Goodkin, 2011; Hegenbarth & American Academy of Pediatrics Committee on Drugs, 2008).
    3) LORAZEPAM DOSE
    a) ADULT: 2 to 4 mg IV initially; repeat every 5 to 10 minutes as needed (Manno, 2003).
    b) CHILD: 0.05 to 0.1 mg/kg IV over 2 to 5 minutes, up to a maximum of 4 mg/dose; may repeat in 5 to 15 minutes as needed (Brophy et al, 2012; Loddenkemper & Goodkin, 2011; Hegenbarth & American Academy of Pediatrics Committee on Drugs, 2008).
    4) Extremely large doses of benzodiazepines may be required in patients with severe intoxication in order to obtain adequate sedation. Titrate dose to clinical response and monitor for hypotension, CNS and respiratory depression, and the need for endotracheal intubation.
    H) HYPERTENSIVE EPISODE
    1) Monitor vital signs regularly. For mild/moderate hypertension without evidence of end organ damage, pharmacologic intervention is generally not necessary. Sedative agents such as benzodiazepines may be helpful in treating hypertension and tachycardia in agitated patients, especially if a sympathomimetic agent is involved in the poisoning.
    2) For hypertensive emergencies (severe hypertension with evidence of end organ injury (CNS, cardiac, renal), or emergent need to lower mean arterial pressure 20% to 25% within one hour), sodium nitroprusside is preferred. Nitroglycerin and phentolamine are possible alternatives.
    3) SODIUM NITROPRUSSIDE/INDICATIONS
    a) Useful for emergent treatment of severe hypertension secondary to poisonings. Sodium nitroprusside has a rapid onset of action, a short duration of action and a half-life of about 2 minutes (Prod Info NITROPRESS(R) injection for IV infusion, 2007) that can allow accurate titration of blood pressure, as the hypertensive effects of drug overdoses are often short lived.
    4) SODIUM NITROPRUSSIDE/DOSE
    a) ADULT: Begin intravenous infusion at 0.1 microgram/kilogram/minute and titrate to desired effect; up to 10 micrograms/kilogram/minute may be required (American Heart Association, 2005). Frequent hemodynamic monitoring and administration by an infusion pump that ensures a precise flow rate is mandatory (Prod Info NITROPRESS(R) injection for IV infusion, 2007). PEDIATRIC: Initial: 0.5 to 1 microgram/kilogram/minute; titrate to effect up to 8 micrograms/kilogram/minute (Kleinman et al, 2010).
    5) SODIUM NITROPRUSSIDE/SOLUTION PREPARATION
    a) The reconstituted 50 mg solution must be further diluted in 250 to 1000 mL D5W to desired concentration (recommended 50 to 200 mcg/mL) (Prod Info NITROPRESS(R) injection, 2004). Prepare fresh every 24 hours; wrap in aluminum foil. Discard discolored solution (Prod Info NITROPRESS(R) injection for IV infusion, 2007).
    6) SODIUM NITROPRUSSIDE/MAJOR ADVERSE REACTIONS
    a) Severe hypotension; headaches, nausea, vomiting, abdominal cramps; thiocyanate or cyanide toxicity (generally from prolonged, high dose infusion); methemoglobinemia; lactic acidosis; chest pain or dysrhythmias (high doses) (Prod Info NITROPRESS(R) injection for IV infusion, 2007). The addition of 1 gram of sodium thiosulfate to each 100 milligrams of sodium nitroprusside for infusion may help to prevent cyanide toxicity in patients receiving prolonged or high dose infusions (Prod Info NITROPRESS(R) injection for IV infusion, 2007).
    7) SODIUM NITROPRUSSIDE/MONITORING PARAMETERS
    a) Monitor blood pressure every 30 to 60 seconds at onset of infusion; once stabilized, monitor every 5 minutes. Continuous blood pressure monitoring with an intra-arterial catheter is advised (Prod Info NITROPRESS(R) injection for IV infusion, 2007).
    8) NITROGLYCERIN/INDICATIONS
    a) May be used to control hypertension, and is particularly useful in patients with acute coronary syndromes or acute pulmonary edema (Rhoney & Peacock, 2009).
    9) NITROGLYCERIN/ADULT DOSE
    a) Begin infusion at 10 to 20 mcg/min and increase by 5 or 10 mcg/min every 5 to 10 minutes until the desired hemodynamic response is achieved (American Heart Association, 2005). Maximum rate 200 mcg/min (Rhoney & Peacock, 2009).
    10) NITROGLYCERIN/PEDIATRIC DOSE
    a) Usual Dose: 29 days or Older: 1 to 5 mcg/kg/min continuous IV infusion. Maximum 60 mcg/kg/min (Laitinen et al, 1997; Nam et al, 1989; Rasch & Lancaster, 1987; Ilbawi et al, 1985; Friedman & George, 1985).
    I) BODY TEMPERATURE ABOVE REFERENCE RANGE
    1) Hyperthermia should be managed with external cooling and sedation with benzodiazepines. Avoid phenothiazines.
    J) MONITORING OF PATIENT
    1) Monitor vital signs (including temperature) and mental status.
    2) No specific lab work is needed in most patients.
    3) Monitor creatinine phosphokinase in patients with prolonged agitation, seizures or coma.
    4) Monitor renal function and urine output in patients with rhabdomyolysis.
    5) Obtain an ECG and institute continuous cardiac monitoring in patients with moderate to severe toxicity (agitation, delirium, seizures, coma, hypotension).
    K) RHABDOMYOLYSIS
    1) SUMMARY: Early aggressive fluid replacement is the mainstay of therapy and may help prevent renal insufficiency. Diuretics such as mannitol or furosemide may be added if necessary to maintain urine output but only after volume status has been restored as hypovolemia will increase renal tubular damage. Urinary alkalinization is NOT routinely recommended.
    2) Initial treatment should be directed towards controlling acute metabolic disturbances such as hyperkalemia, hyperthermia, and hypovolemia. Control seizures, agitation, and muscle contractions (Erdman & Dart, 2004).
    3) FLUID REPLACEMENT: Early and aggressive fluid replacement is the mainstay of therapy to prevent renal failure. Vigorous fluid replacement with 0.9% saline (10 to 15 mL/kg/hour) is necessary even if there is no evidence of dehydration. Several liters of fluid may be needed within the first 24 hours (Walter & Catenacci, 2008; Camp, 2009; Huerta-Alardin et al, 2005; Criddle, 2003; Polderman, 2004). Hypovolemia, increased insensible losses, and third spacing of fluid commonly increase fluid requirements. Strive to maintain a urine output of at least 1 to 2 mL/kg/hour (or greater than 150 to 300 mL/hour) (Walter & Catenacci, 2008; Camp, 2009; Erdman & Dart, 2004; Criddle, 2003). To maintain a urine output this high, 500 to 1000 mL of fluid per hour may be required (Criddle, 2003). Monitor fluid input and urine output, plus insensible losses. Monitor for evidence of fluid overload and compartment syndrome; monitor serum electrolytes, CK, and renal function tests.
    4) DIURETICS: Diuretics (eg, mannitol or furosemide) may be needed to ensure adequate urine output and to prevent acute renal failure when used in combination with aggressive fluid therapy. Loop diuretics increase tubular flow and decrease deposition of myoglobin. These agents should be used only after volume status has been restored, as hypovolemia will increase renal tubular damage. If the patient is maintaining adequate urine output, loop diuretics are not necessary (Vanholder et al, 2000).
    5) URINARY ALKALINIZATION: Alkalinization of the urine is not routinely recommended, as it has never been documented to reduce nephrotoxicity, and may cause complications such as hypocalcemia and hypokalemia (Walter & Catenacci, 2008; Huerta-Alardin et al, 2005; Brown et al, 2004; Polderman, 2004). Retrospective studies have failed to demonstrate any clinical benefit from the use of urinary alkalinization (Brown et al, 2004; Polderman, 2004; Homsi et al, 1997).
    6) MANNITOL/INDICATIONS
    a) Osmotic diuretic used in the management of rhabdomyolysis and myoglobinuria (Zimmerman & Shen, 2013).
    7) RHABDOMYOLYSIS/MYOGLOBINURIA
    a) ADULT: TEST DOSE: (for patients with marked oliguria or those with inadequate renal function) 0.2 g/kg IV as a 15% to 25% solution infused over 3 to 5 minutes to produce a urine flow of at least 30 to 50 mL/hr; a second test dose may be given if urine flow does not increase within 2 to 3 hours. The patient should be reevaluated if there is inadequate response following the second test dose (Prod Info MANNITOL intravenous injection, 2009). TREATMENT DOSE: 50 to 100 g IV as a 15% to 25% solution may be used. The rate should be adjusted to maintain urinary output at 30 to 50 mL/hour (Prod Info mannitol IV injection, urologic irrigation, 2006) OR 300 to 400 mg/kg or up to 100 g IV administered as a single dose (Prod Info MANNITOL intravenous injection, 2009).
    b) PEDIATRIC: Dosing has not been established in patients less than 12 years of age(Prod Info Mannitol intravenous injection, 2009). TEST DOSE (for patients with marked oliguria or those with inadequate renal function): 0.2 g/kg or 6 g/m(2) body surface area IV as a 15% to 25% solution infused over 3 to 5 minutes to produce a urine flow of at least 30 to 50 mL/hr; a second test dose may be given if urine flow does not increase; TREATMENT DOSE: 0.25 to 2 g/kg or 60 g/m(2) body surface area IV as a 15% to 20% solution over 2 to 6 hours; do not repeat dose for persistent oliguria (Prod Info MANNITOL intravenous injection, 2009).
    8) ADVERSE EFFECTS
    a) Fluid and electrolyte imbalance, in particular sodium and potassium; expansion of the extracellular fluid volume leading to pulmonary edema or CHF exacerbations(Prod Info MANNITOL intravenous injection, 2009).
    9) PRECAUTION
    a) Contraindicated in well-established anuria or impaired renal function not responding to a test dose, pulmonary edema, CHF, severe dehydration; caution in progressive oliguria and azotemia; do not add to whole blood for transfusions(Prod Info Mannitol intravenous injection, 2009); enhanced neuromuscular blockade observed with tubocurarine(Miller et al, 1976).
    10) MONITORING PARAMETERS
    a) Renal function, urine output, fluid balance, serum potassium, serum sodium, and serum osmolality (Prod Info Mannitol intravenous injection, 2009).
    L) HYPOTENSIVE EPISODE
    1) If hypotension is believed to be secondary to severe tachycardia or other dysrhythmias, initial therapy should be focused on control of dysrhythmias. A short acting agent such as esmolol is preferred for control of tachycardia if needed. Physostigmine may also provide temporary slowing of severe tachycardia.
    2) ESMOLOL
    a) ADULT DOSE/ADMINISTRATION - Prepare a solution containing 10 milligrams esmolol per milliliter of a compatible intravenous solution (Prod Info Brevibloc(R), esmolol hydrochloride, 1998).
    1) CAUTION - Esmolol is a short-acting beta-adrenergic blocking agent with negative inotropic effects. Esmolol may be hazardous in patients with bronchospastic disease (asthmatics, COPD) (Prod Info Brevibloc(R), esmolol hydrochloride, 1998) or myocardial depression (Gomez et al, 1992).
    2) LOADING DOSE - Infuse 500 micrograms/kilogram of body weight for 1 minute (Prod Info Brevibloc(R), esmolol hydrochloride, 1998).
    3) MAINTENANCE DOSE - Follow loading dose with infusion of 50 micrograms/kilogram/minute for 4 minutes (Prod Info Brevibloc(R), esmolol hydrochloride, 1998).
    4) EVALUATION OF RESPONSE - If inadequate response to initial loading dose and 4-minute maintenance dose, repeat loading dose (infuse 500 micrograms/kilogram for 1 minute) followed by a maintenance infusion of 100 micrograms/kilogram/minute for 4 minutes. Reevaluate therapeutic effect.
    5) If response is inadequate, repeat loading dose and increase the maintenance dose by increments of 50 micrograms/kilogram/minute, administered as above (Prod Info Brevibloc(R), esmolol hydrochloride, 1998).
    6) ENDPOINT OF THERAPY - When desired heart rate or safety endpoint (blood pressure) is reached:
    7) Omit loading dose and reduce incremental dose in maintenance infusion from 25 to 50 micrograms/kilogram/minute or lower;
    8) Or increase interval between titration steps from 5 to 10 minutes (Prod Info Brevibloc(R), esmolol hydrochloride, 1998).
    9) USUAL ADULT DOSAGE - 25 to 200 micrograms/kilogram/minute (Prod Info Brevibloc(R), esmolol hydrochloride, 1998)
    b) PEDIATRIC DOSE/ADMINISTRATION - Safety and effectiveness of esmolol has not been established in children (Prod Info Brevibloc(R), esmolol hydrochloride, 1998).
    3) SUMMARY
    a) Infuse 10 to 20 milliliters/kilogram of isotonic fluid and keep the patient supine. If hypotension persists, administer dopamine or norepinephrine. Consider central venous pressure monitoring to guide further fluid therapy.
    4) DOPAMINE
    a) DOSE: Begin at 5 micrograms per kilogram per minute progressing in 5 micrograms per kilogram per minute increments as needed (Prod Info dopamine hcl, 5% dextrose IV injection, 2004). If hypotension persists, dopamine may need to be discontinued and a more potent vasoconstrictor (eg, norepinephrine) should be considered (Prod Info dopamine hcl, 5% dextrose IV injection, 2004).
    b) CAUTION: If ventricular dysrhythmias occur, decrease rate of administration (Prod Info dopamine hcl, 5% dextrose IV injection, 2004). Extravasation may cause local tissue necrosis, administration through a central venous catheter is preferred (Prod Info dopamine hcl, 5% dextrose IV injection, 2004).
    5) NOREPINEPHRINE
    a) PREPARATION: 4 milligrams (1 amp) added to 1000 milliliters of diluent provides a concentration of 4 micrograms/milliliter of norepinephrine base. Norepinephrine bitartrate should be mixed in dextrose solutions (dextrose 5% in water, dextrose 5% in saline) since dextrose-containing solutions protect against excessive oxidation and subsequent potency loss. Administration in saline alone is not recommended (Prod Info norepinephrine bitartrate injection, 2005).
    b) DOSE
    1) ADULT: Dose range: 0.1 to 0.5 microgram/kilogram/minute (eg, 70 kg adult 7 to 35 mcg/min); titrate to maintain adequate blood pressure (Peberdy et al, 2010).
    2) CHILD: Dose range: 0.1 to 2 micrograms/kilogram/minute; titrate to maintain adequate blood pressure (Kleinman et al, 2010).
    3) CAUTION: Extravasation may cause local tissue ischemia, administration by central venous catheter is advised (Peberdy et al, 2010).

    1) SCOPOLAMINE PATCHES - Prevention is the most effective method. Patients should be instructed to wash their hands thoroughly after placing or handling a patch, and prior to inserting contact lenses.
    2) If contamination is realized soon after the mistake, irrigation may have some value.
    B) EYE IRRIGATION, ROUTINE: Remove contact lenses and irrigate exposed eyes with copious amounts of room temperature 0.9% saline or water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist after 15 minutes of irrigation, an ophthalmologic examination should be performed (Peate, 2007; Naradzay & Barish, 2006).

Enhanced Elimination

    A) EXTRACORPOREAL ELIMINATION
    1) Peritoneal dialysis and hemodialysis are not useful (Worth et al, 1983).

Case Reports

    A) SPECIFIC AGENT
    1) ATROPINE OCCUPATIONAL AEROSOL EXPOSURE: Anticholinergic poisoning occurred in a 28-year-old respiratory therapist whose only exposure to anticholinergics was via aerosol administration to her patients; she had given 10 treatments in the previous 24 hours. Signs included anxiety, palpitations, dry mouth, blurred vision, dizziness, and flushed hot skin. All signs resolved over 48 hours with only supportive treatment (Larkin, 1991).

Summary

    A) ADULTS: Varies with the specific medication. In general, patients will have to ingest large doses of plant products (or make a tea) to develop symptoms.

    7.2.2) PEDIATRIC
    A) SPECIFIC SUBSTANCE
    1) ACLIDINIUM BROMIDE
    a) Safety and effectiveness have not been established in pediatric patients (Prod Info TUDORZA(TM) PRESSAIR(TM) oral inhalation powder, 2012).
    2) ATROPINE:
    a) BRADYCARDIA (PALS GUIDELINES)
    1) IV/IO: 0.02 mg/kg; maximum single dose of 0.5 mg. May repeat dose once if needed (Kleinman et al, 2010).
    2) ET: 0.04 to 0.06 mg/kg; follow with 5 mL normal saline flush and 5 manual ventilations (Kleinman et al, 2010).
    3) A minimum single dose of 0.1 mg is recommended in the PALS guideline; however, this recommendation has been questioned due to the lack of evidence for paradoxical bradycardia with low mg/kg doses and the potential for atropine overdosing in neonates and infants less than 5 kilograms (Barrington, 2011). Atropine has been shown to appropriately increase (or appropriately attenuate a drop in) heart rate in term and preterm neonates at doses of 0.01 to 0.02 mg/kg, which equaled single doses less than 0.1 mg (Dempsey et al, 2006; Roberts et al, 2006; Andriessen et al, 2004; Oei et al, 2002).
    b) ORGANOPHOSPHATE OR CARBAMATE POISONING:
    1) Moderate/Severe Cholinergic Symptoms: 0.05 mg/kg IV/IM/IO (maximum 4 mg/dose); repeat every 5 to 10 minutes until pulmonary resistance improves or secretions resolve (Rotenberg & Newmark, 2003; Lifshitz et al, 1999; Lifshitz et al, 1994).
    2) Severe Cholinergic Crisis: 0.05 to 0.1 mg/kg IV/IM/IO; repeat every 5 to 10 minutes until pulmonary resistance improves or secretions resolve (Rotenberg & Newmark, 2003; Lifshitz et al, 1999; Lifshitz et al, 1994). For dosing via ET tube, increase the parenteral dose 2 to 3 times and give via suction catheter (Rotenberg & Newmark, 2003).
    3) AUTOINJECTOR (ATROPEN(R) DOSING:
    a) Less than 7 kg: 0.25 mg IM
    b) 7 to 18 kg: 0.5 mg IM
    c) 18 to 41 kg: 1 mg IM
    d) Greater than 41 kg: 2 mg IM
    e) For mild cholinergic symptoms (ie, blurred vision, tearing, tachycardia or bradycardia), 1 injection is recommended. If the patient has severe symptoms (severe difficulty breathing, severe muscle twitching, convulsions, unconsciousness), 1 injection should be given followed 10 minutes later by 2 additional injections given in rapid succession (Prod Info ATROPEN(R) IM injection, 2005). Autoinjectors (AIs) are recommended for IM delivery as opposed to IM administration with the needle and syringe method. AIs provide superior delivery by releasing the medication as the needle punctures the tissue compared with traditional IM delivery which creates a small pool of medication. AIs produce a quicker peak (less than 5 minutes) compared with the needle and syringe method (25 minutes), which is necessary for severe cholinergic crisis (Rotenberg & Newmark, 2003).
    c) PREMEDICATION, ANESTHESIA INDUCTION OR KETAMINE SEDATION
    1) IV/IM/subQ: 0.01 to 0.02 mg/kg 2 to 15 minutes prior to induction.

    2) ORAL: 0.03 to 0.05 mg/kg 20 to 60 minutes prior to induction; Maximum 2 mg/dose (Bhatnagar et al, 2008; Shaw et al, 2000; Crean et al, 1991).
    d) PREMEDICATION, RAPID SEQUENCE INTUBATION
    1) 0.02 mg/kg IV 1 to 2 minutes prior to intubation; Minimum single dose, 0.1 mg; maximum single dose of 0.5 mg in children and 1 mg in adolescents (Gerardi et al, 1996).

    5) SCOPOLAMINE
    a) The estimated fatal dose of scopolamine in a child is as low as 10 mg (Thakkar & Lasser, 1972).

Maximum Tolerated Exposure

    A) GENERAL/SUMMARY
    1) The anticholinergic syndrome has a rapid onset and easily recognizable symptomatology. Clinical judgment is more relevant than drug levels or an estimation of the amount ingested.
    B) SPECIFIC SUBSTANCE
    1) ACLIDINIUM
    a) A single inhaled dose of up to 6,000 mcg aclidinium bromide (7.5 times the recommended human daily dose) in 16 healthy volunteers was well-tolerated with no systemic anticholinergic or other adverse effects reported (Prod Info TUDORZA(TM) PRESSAIR(TM) oral inhalation powder, 2012).
    2) ATROPINE
    a) ADULT: A 25-year-old recovered after ingesting 1 g of atropine while under the influence of ethanol (Michelson et al, 1991).
    b) PEDIATRIC: Healthy children tolerated high doses of atropine with relatively mild symptoms in 248 cases of accidental injections with personal automatic atropine injectors (Amitai et al, 1991).
    c) EYE PREPARATIONS: Signs and symptoms of anticholinergic poisoning may occur following oral ingestion or ocular instillation of as little as 4 to 5 drops (probably less in children) of ocular solutions containing 4% atropine (Goldfrank et al, 1982; Adler et al, 1982; Hoefnagel, 1961; Heath, 1950).

    3) BENZTROPINE
    a) ADOLESCENT: A 13-year-old boy ingested 40 mg, became comatose, and developed seizures and nosebleeds (Prod Info Poison Control Monograph, Cogentin(R). benztropine, 1984).
    b) ADULT: A 51-year-old woman ingested 120 to 124 mg, became confused, incoherent, and developed sinus tachycardia, and recovered(Prod Info Poison Control Monograph, Cogentin(R). benztropine, 1984).
    4) CLIDINIUM
    a) ADULT: Mild mydriasis and persistent sinus tachycardia (110 to 125 bpm for 11 hours) were reported in a 24-year-old man following 2 overdose ingestions, separated by 90 minutes, of a combination medication containing chlordiazepoxide 5 mg and clidinium 2.5 mg (amounts ingested per overdose: chlordiazepoxide 50 mg and clidinium 25 mg). With supportive care, the patient recovered and was discharged without sequelae (Richardson & Edwards, 2009).
    5) CYCLOPENTOLATE
    a) CHILD: A 4.5-year-old child experienced retching, hallucinations, incoherent babbling, hyperactivity alternating with somnolence, facial flushing, and tachycardia after a total of 6 drops (approximately 6 mg) of 2% cyclopentolate solution were instilled in his eyes. Symptoms resolved 36 hours later (Adcock, 1971).
    6) DIPHENIDOL

    7) GLYCOPYRROLATE
    a) ADULT: A 22-year-old woman was given 0.2 mg glycopyrrolate intravenously as a preanesthetic medication and 10 minutes later the patient experienced anticholinergic effects, including agitation, headache, tachycardia, pupil dilation, and dry mouth. Physostigmine was given and symptoms resolved within 24 hours.(Grum & Osborne, 1991).
    8) METHSCOPOLAMINE NITRATE
    a) ADULT: Transient headache and dry mouth were the only toxic manifestations after inadvertent inhalation of 32 mg via a nebulizer in a 65-year-old man (Gross & Skorodin, 1985).

    a) ADULT: A 24-year-old man ingested 5 g, experienced neuropsychiatric symptoms (confusion, agitation, hallucinations) that lasted 24 hours, and was discharged three days later (Furlanut et al, 1985).
    b) ADULT: A 25-year-old man who ingested a single 1200- to 1500-mg dose of orphenadrine, developed tachycardia and CNS abnormalities (delirium with severe agitation, hallucinations, delusions, and paranoid thinking) that were corrected with physostigmine (single IV dose of 1 mg) (Snyder et al, 1976).
    c) PEDIATRIC: Small children have survived ingestions of up to 1.4 g (Stoddart et al, 1968; Gill & Sowerby, 1975).
    10) OXYBUTYNIN
    a) ADULT: A 34-year-old experienced severe symptoms (disorientation, tachycardia, ventricular ectopy, bigeminy) following ingestion of 100 mg (Banerjee et al, 1991).
    11) SCOPOLAMINE
    a) ADULT
    1) Following acute poisonings, the lowest ingested dose of scopolamine producing life-threatening symptoms was 2 to 4 mg in a study of 115 patients (Hooper et al, 1979). A 0.45-mg dose has caused toxic psychosis (Goldfrank et al, 1982).
    2) CASE REPORT: An 83-year-old woman presented to the emergency department with a decreased level of consciousness (Glasgow Coma Scale score of 8), and intermittent myoclonus after ingesting a single 10-mg dose of scopolamine instead of the prescribed butylscopolamine 10 mg three times daily. Vital signs demonstrated hypertension (167/82 mmHg), tachycardia (127 beats/min) and hyperthermia (38 degrees C). Bilateral mydriasis that was unresponsive to light, and a tetrapyramidal syndrome with myoclonus of the left leg and hypertonia of the extremities were also noted. Following administration of a pyridostigmine infusion and supportive care, the patient gradually improved and was discharged a few days later with baseline mild cognitive deficit (Van de Velde et al, 2015).
    b) PEDIATRIC: Twelve hours after applying a transdermal patch, a 6-year-old experienced blurred vision, confusion, and disorientation (Sennhauser & Schwarz, 1986).
    c) EYE PREPARATIONS: Signs and symptoms of anticholinergic poisoning may occur following oral ingestion or ocular instillation of as little as 4 to 5 drops (probably less in children) of ocular solutions containing 0.25% scopolamine (Goldfrank et al, 1982; Adler et al, 1982; Hoefnagel, 1961; Heath, 1950).
    12) TIOTROPIUM
    a) ADULT: A 74-year-old man with a history of COPD, atrial fibrillation, and renal insufficiency and was taking tiotropium 18 mcg daily as part of his medication regimen, presented to a hospital with dyspnea and tachycardia (130 beats/min). After hospital admission he received metoprolol which decreased his heart rate to 80 to 90 beats/min. Twenty four hours later, he inadvertently received, via inhalation, 5 18-mcg capsules of tiotropium instead of the prescribed 1 18-mcg capsule. Approximately 15 minutes later, the patient's heart rate increased to 160 beats/min. With intravenous administration of metoprolol and diltiazem, his heart rate returned to the 80s, although it continued to be difficult to control throughout his hospitalization (Gregory et al, 2010)
    13) TOLTERODINE
    a) CHILD: A 27-month-old ingested 10 to 14 mg of tolterodine and was hospitalized overnight with symptoms of dry mouth. The patient recovered following decontamination with activated charcoal (Prod Info Detrol(R), tolterodine, 1998).
    14) TRIHEXYPHENIDYL
    a) Doses of 15 to 60 mg have produced euphoria, hallucinations, tachycardia, and blurred vision (Crawshaw & Mullen, 1984).
    b) ADULT: Two patients, ages 37 and 54 years, who ingested 42 and 150 mg, respectively, developed severe excitement. The patients had visual hallucinations, tension, coarse digital tremor, dryness of mouth, hyperreflexia, dilated pupils, and labile excitement. Disturbances subsided with no specific treatment (Stephens, 1967).
    15) TROPICAMIDE
    a) There have been several reports of heroin users intravenously injecting 1% tropicamide ophthalmic solution. Large doses of tropicamide (up to 1 gram) have reportedly induced visual and auditory hallucinations, and chronic administration has resulted in anticholinergic toxicity, including agitation, hypertension, tachycardia, mydriasis, xerostomia, and mental confusion (Bozkurt et al, 2015; Spagnolo et al, 2013).

    2) CHILDREN: Serum atropine concentrations were from 7.5 to 69 nanograms/mL in a study of 248 cases of accidental injections with personal automatic atropine injectors (Amitai et al, 1991).
    b) BENZTROPINE
    1) A 38-year-old man had a peak serum benztropine level of 100 mcg/L approximately 24 hours after ingesting an unknown amount of benztropine mesylate 1-mg tablets. Symptoms of intoxication persisted until serum benztropine concentrations had decreased to 9 mcg/L (Fahy et al, 1989).
    2) After a fatal benztropine overdose, postmortem benztropine concentrations were: blood: 0.3 mg/L; liver: 8.7 mg/kg; urine 5.6 mg/L; vitreous humor: 0.3 mg/L (Lynch & Kotsos, 2001).
    3) A peak serum benztropine level was reported at 100 mcg/L on day 2 following an overdose of an unknown quantity in a 33-year-old man. Activated charcoal (30 g) was administered on admission. Physostigmine was given in 20 doses (total of 35.5 mg) for anticholinergic syndrome which lasted 8 days (Arnold et al, 1987).
    c) DICYCLOMINE
    1) Two 10-week-old infants died and it was believed to be secondary to dicyclomine. Analysis using gas chromatography/mass spectrometry reported blood levels of 0.505 and 0.221 mcg/mL, respectively (Gariott et al, 1984).
    d) ORPHENADRINE
    1) Toxicity begins at 2 to 3 mg/L; concentrations of 4 to 8 mg/L have been fatal; however, survival occurred in a patient with a level of 16.2 mg/L (Winek, 1976; Clarke et al, 1985).
    e) SCOPOLAMINE
    1) A 6-year-old child with anticholinergic delirium from a transdermal scopolamine patch had a free scopolamine level in plasma of 890 picograms/mL (7.93 nanomoles/L) and 113 nanograms/mL (0.37 mcmol/L) in urine 5 hours after the patch was removed (Sennhauser & Schwarz, 1986).
    f) TRIHEXYPHENIDYL HYDROCHLORIDE
    1) A 48-year-old man was found dead next to partially used containers of trihexyphenidyl hydrochloride (benzhexol), erythromycin, terbutaline elixir, nystatin lozenges, and salbutamol rotacaps. Toxicological analysis revealed only significant levels of trihexyphenidyl in the blood, liver and gastric contents. Femoral artery blood concentration was 0.12 mg/L (Gall et al, 1995).
    2) A 59-year-old woman, with a history of paranoid disorder, was found dead in her home. Her medication list included fluphenazine injection 25 mg, administered 3 weeks before her death, and trihexyphenidyl 15 mg per day. Post-mortem toxicologic analysis revealed trihexyphenidyl concentrations in the femoral venous blood and urine of 0.053 mg/L and 0.560 mg/L, respectively. The presence of hydroxy-trihexyphenidyl, a metabolite, was also confirmed but was not quantified (Petkovic et al, 2011).

Toxicity Information

    7.7.1) TOXICITY VALUES
    A) BENZTROPINE MESYLATE
    1) LD50- (ORAL)MOUSE:
    a) 94 mg/kg (Prod Info Poison Control Monograph, Cogentin(R). benztropine, 1984)
    B) IPRATROPIUM BROMIDE Pers Comm, 1989a
    1) LD50- (ORAL)MOUSE:
    a) 1001 to 2010 mg/kg
    2) LD50- (ORAL)RAT:
    a) 1667 to 4000 mg/kg

Toxicologic Mechanism

    A) Drugs with anticholinergic properties primarily antagonize acetylcholine competitively at the neuroreceptor site. Cardiac muscle, exocrine gland, CNS, and smooth muscle are most markedly affected. Reversal of this antagonism is achieved by increasing the available acetylcholine.
