Sodium calcium edetate (sodium calcium EDTA), also known as edetate calcium disodium among other names, is a medication primarily used to treat lead poisoning,[2] including both short-term and long-term lead poisoning.[3] Sodium calcium edetate came into medical use in the United States in 1953.[3]

Chelation agent

Sodium calcium edetate is in the chelating agent family of medication.[3] It is a salt of edetate with two sodium and one calcium atoms.[4] It works by binding to a number of heavy metals, which renders them almost inert and allows them to leave the body in the urine.[3]

Edetate disodium (Endrate) is a different formulation which does not have the same effects.[3]

Medical use

Sodium calcium edetate's primary use is to treat lead poisoning,[2] for which it is an alternative to succimer.[3] It is given by slow injection into a vein or into a muscle.[2]

For lead encephalopathy sodium calcium edetate is typically used together with dimercaprol.[3] It may also be used to treat plutonium poisoning.[5] It does not appear to be useful for poisoning by tetra-ethyl lead.[3]

Side effects

Common side effects include pain at the site of injection.[3] Other side effects may include kidney problems, diarrhea, fever, muscle pains, and low blood pressure.[2] Benefits when needed in pregnancy are likely greater than the risks.[3]

History

Sodium calcium edetate came into medical use in the United States in 1953.[3] It is on the World Health Organization's List of Essential Medicines.[6]
