Used primarily as an antidote in cases of organophosphate poisoning, this compound functions by reactivating acetylcholinesterase enzymes inhibited by toxic agents such as nerve gases and certain pesticides. It is especially effective when administered promptly after exposure, helping to restore normal neuromuscular function. Its ability to cross the blood-brain barrier enhances its effectiveness in reversing central nervous system effects of poisoning. Due to its stability and reactivation capacity, it is considered in both military and civilian medical preparedness for chemical emergencies.
