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] This includes short term and long term lead poisoning.[2] For lead encephalopathy it is typically used together with dimercaprol.[2] It does not appear to be useful for tetraethyllead toxicity.[2] It is given by slow injection into a vein or into a muscle.[1]

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] 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 a number of heavy metals which allows them to leave the body in the urine.[2]

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.[4] In the United States a course of treatment costs 50 to 100 USD as of 2015.[5] Edetate disodium is a different formulation which does not have the same effects.[2]

Medical uses[edit]

The primarily use is to treat lead poisoning.[1] In lead toxicity it is an alternative to succimer.[2]

It may also be used for plutonium toxicity.[6]
