62 results about "Sodium calcium edetate" patented technology

Sodium calcium edetate (sodium calcium EDTA), also known as edetate calcium disodium among other names, is a medication primarily used to treat lead poisoning. This includes short term and long term lead poisoning. For lead encephalopathy it is typically used together with dimercaprol. It does not appear to be useful for tetraethyllead toxicity. It is given by slow injection into a vein or into a muscle.
