Atropine-mechanism of action in organophosphate poisoning-
Reactivation of choline-esterase
Acts on central and peripheral post.ganglionic receptors
Acts on central and peripheral cholinergic receptors
Acts on peripheral cholinergic receptors only
Ans. is 'c' i.e., Acts on central and peripheral cholinergic receptors o In organophosphate poisoning, atropine counteracts the peripheral muscarinic symptoms and at higher doses central effects as well. o Atropine does not reverse nicotinic action i.e., peripheral muscular paralysis.
