  • Pralidoxime iodide is a reactivator of acetylcholinesterase (AChE). Pralidoxime iodide reactivates nerve agent, which inhibits AChE via direct nucleophilic attack by the oxime moiety on the phosphorus center of the bound nerve agent. Pralidoxime iodide is an antidote for organophosphate poisoning[1][2].
