Several drugs are used in the treatment of lead poisoning, including edetate disodium calcium (CaEDTA), dimercaperol (British anti-Lewisite), D-penicillamine, and meso-2,3-dimercaptosuccinic acid (succimer).

Edetate calcium disodium (CaNa2EDTA) promotes urinary excretion of lead and is used in children with levels greater than 45; it is administered IM or IV.
Histopathological studies in patients with SC nodules secondary to treatment with a formulation consisting of apomorphine and sodium metabisulphite have recently demonstrated panniculitis in the absence of skin patch test response to either component in the formulation, suggesting that the skin response to apomorphine causes a delayed type-I hypersensitivity reaction.[2] Another similar study used a formulation consisting of apomorphine, sodium metabisulphite, and sodium edetate (EDTA).
The only effective test used for bone lead levels is the disodium edetate (EDTA) chelating agent test.
Imprimis Pharmaceuticals, Inc., a pharmaceutical company focused on the production and dispensing of high quality innovative compounded medications, today announced the availability of a significantly lower-cost compounded alternative to Valeant's Calcium Disodium Versenate (edetate calcium disodium injection, USP), commonly used to stabilize and treat patients exposed to lead poisoning.
An additive often used in these preparations is disodium edetate (EDTA).
