Pharmacologic Category
Heavy Metal Antagonists; Chelating Agent. Antidotes. (ATC-Code: V03AB03; S01XA05).
Mechanism of action
Edetate calcium disodium (calcium EDTA) is a heavy metal antagonist which chelates lead, zinc, and other heavy metals. Calcium is displaced by divalent and trivalent heavy metals, forming a nonionizing soluble complex which is excreted in urine.
Therapeutic use
Parenterally administered calcium EDTA is used for the reduction of blood and mobile depot lead in the treatment of acute and chronic lead poisoning and lead encephalopathy. Useful in poisonings caused by alkyl lead compounds (e.g. tetraethyl lead).
Pregnancy and lactiation implications
Adverse events observed in some animal reproduction studies. Chelation therapy during pregnancy is for maternal benefit only and should be limited to the treatment of severe, symptomatic lead poisoning. Use with caution during lactation.
Unlabeled use
Possibly useful in poisoning by zinc, manganese, and certain heavy radioisotopes.
Contraindications
Hypersensitivity to edetate calcium disodium or any component of the formulation. Severe renal disease or anuria. Hepatitis.
Warnings and precautions
Risk of nephrotoxicity (renal tubular acidosis and fatal nephrosis may occur), especially with high doses. ECG changes may occur during therapy. Anuria, increasing proteinuria, or hematuria may also occur. Use with extreme caution in lead encephalopathy or cerebral edema (I.V. infusion associated with lethal increase in intracranial pressure). Use with caution in renal impairment. Edetate calcium disodium can produce serious and sometimes fatal toxic effects.
