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

In Vivo	Pralidoxime (10-150 mg/kg; intramuscular administration, once) reverses paraoxon-induced respiratory toxicity in mice[3]. Animal Model: F1B6D2 mice (male, administered subcutaneously diethylparaoxon)[3] Dosage: 10, 50, 100, and 150 mg/kg Administration: Intramuscular administration, once Result: Induced a partial, albeit complete, reversal of respiratory toxicity at 50 mg/kg, and completely reversed diethylparaoxon-induced respiratory toxicity in mice at 150 mg/kg.
