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] This includes short term and long term lead poisoning.[3] For lead encephalopathy it is typically used together with dimercaprol.[3] It does not appear to be useful for tetraethyllead toxicity.[3] It is given by slow injection into a vein or into a muscle.[2]

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] 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 a number of heavy metals which allows them to leave the body in the urine.[3]

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, the most effective and safe medicines needed in a health system.[5] In the United States a course of treatment costs 50 to 100 USD as of 2015.[6] Edetate disodium is a different formulation which does not have the same effects.[3]

Uses

Medical

Sodium calcium edetate's primarily 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.[7] It does not appear to be useful for poisoning by tetra-ethyl lead.[3]

Dosage

The defined daily dose is not established[1]

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.[8] 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 is a different formulation which does not have the same effects.[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.[9] As of 2015 in the United States, a course of treatment costs US$50 to US$100.[6]
