Pralidoxime is one pharmacological agent available to treat patients with symptomatic organophosphate exposure. How does this drug work?
What will be an ideal response?
Suggested response: Pralidoxime hydrochloride reactivates acetylcholinesterase and is effective at restoring skeletal muscle function, but is less effective at reversing muscarinic signs. Over time, the bond between organophosphate and cholinesterase becomes permanent and the effectiveness of pralidoxime diminishes. The current recommendation is administration within 48 hours of organophosphate poisoning.
