-IDENTIFICATION
SYNONYMS
Ca-DTPA Calcium trisodium DTPA Calcium trisodium nitrilodiethylenedintrilopenta-acetate NSC-34249 Pentetate calcium trisodium Pentetato calcico trisodico Trisodium calcium diethylenetriaminepentaacetate Molecular formula: C14-H18-Ca-N3-Na3-O10 CAS 12111-24-9
IDENTIFIERS
USES/FORMS/SOURCES
Pentetate calcium trisodium (Ca-DTPA) is used to treat individuals with known or suspected internal contamination with transuranium ions, specifically plutonium, americium, and/or curium, to increase rates of elimination (Prod Info pentetate calcium trisodium IV injection, inhalation solution, 2005).
Ca-DTPA is available as a sterile solution in 5 mL single-use clear glass ampoules (1000 mg of Ca-DTPA per ampoule) at a concentration of 200 mg/mL for intravenous use. Each mL has 200 mg of Ca-DTPA (obtained from 158.17 mg pentetic acid, 40.24 mg calcium carbonate and NaOH) in water for injection, USP. If internal contamination is only by inhalation within the preceding 24 hours, patients can receive Ca-DTPA by nebulized inhalation (Prod Info pentetate calcium trisodium IV injection, inhalation solution, 2005).
-CLINICAL EFFECTS
GENERAL CLINICAL EFFECTS
- USES: Pentetate calcium trisodium (Ca-DTPA) is used to treat individuals with known or suspected internal contamination with transuranium ions, specifically plutonium, americium, and/or curium, to increase rates of elimination.
- PHARMACOLOGY: Pentetate calcium trisodium (Ca-DTPA) increases the rates of radiocontaminant elimination by forming stable chelates with metal ions. The calcium ion is exchanged for ions with higher binding capacity. The radioactive chelates are then excreted into the urine by glomerular filtration.
- EPIDEMIOLOGY: Overdose is rare.
Chest pain, fever, chills, headache, lightheadedness, dermatitis, pruritus, nausea, vomiting, metallic taste, diarrhea, and Injection site reactions have been reported following therapeutic use of pentetate zinc trisodium (Ca-DTPA). In addition, Ca-DTPA therapy has been associated with trace element deficiency including zinc, magnesium, and manganese depletion. Cough and/or wheezing have been reported in 2 patients who received nebulized Ca-DTPA; one patient had a history of asthma.

-FIRST AID
FIRST AID AND PREHOSPITAL TREATMENT
- Gastrointestinal decontamination is not recommended; administered via the parenteral or inhalational routes.
-RANGE OF TOXICITY
MINIMUM LETHAL EXPOSURE
- Deaths have been reported in three patients with severe hemochromatosis who received up to 4 times the recommended daily dose via intramuscular injection. After receiving 14 grams of Ca-DTPA, one patient became comatose and died. The other two patients died after 14 days of daily treatment (Prod Info Pentetate Calcium Trisodium Injection, 2004).
MAXIMUM TOLERATED EXPOSURE
- One patient with a less severe case of hemochromatosis did not experience any adverse effects after receiving 30 grams of Ca-DTPA by intravenous injection over 12 days (Anon, 2004).
