Pralidoxime

Pralidoxime reactivates acetylcholinesterase only if irreversible binding to the OP has not already occurred ("ageing"). The acetylcholinesterase enzyme has two parts to it. In organophosphate poisoning, an organophosphate binds to just one end of the acetylcholinesterase enzyme (the esteric site), blocking its activity.
