Sodium calcium edetate

Sodium calcium edetate (sodium calcium EDTA), also known as edetate calcium disodium among other names, is a medication primarily used to treat lead poisoning,[1] including both short-term and long-term lead poisoning.[2] Sodium calcium edetate came into medical use in the United States in 1953.[2]

Chelation agent

Sodium calcium edetate is in the chelating agent family of medication.[2] It is a salt of edetate with two sodium and one calcium atoms.[3] 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.[2]

Edetate disodium is a different formulation which does not have the same effects.[2]

Medical use

Sodium calcium edetate's primarily use is to treat lead poisoning,[1] for which it is an alternative to succimer.[2] It is given by slow injection into a vein or into a muscle.[1]

For lead encephalopathy sodium calcium edetate is typically used together with dimercaprol.[2] It may also be used to treat plutonium poisoning.[4] It does not appear to be useful for poisoning by tetra-ethyl lead.[2]

Side effects

Common side effects include pain at the site of injection.[2] Other side effects may include kidney problems, diarrhea, fever, muscle pains, and low blood pressure.[1] Benefits when needed in pregnancy are likely greater than the risks.[2]

History

Sodium calcium edetate came into medical use in the United States in 1953.[2] It is on the World Health Organization's List of Essential Medicines.[5] As of 2015 in the United States, a course of treatment costs US$50 to US$100.[6]
