What this is
TACT (Trial to Assess Chelation Therapy) 2013 showed marginal CV benefit that generated ongoing controversy; TACT2 (2023) in diabetics failed to replicate. Oral/suppository EDTA products sold for 'plaque removal' have essentially no evidence. Legitimate role is acute inorganic lead toxicity.
Mechanism
Ethylenediaminetetraacetic acid; binds divalent metals (Ca²⁺, Pb²⁺, Fe³⁺, etc.) via tetradentate chelation; IV/IM forms used for lead toxicity; oral has poor absorption
Dose & route
50 mg/kg/day IV for lead (max 2 g); 1-3 g/L oral suppository protocols have no validated evidence
