Antidote in Atropine poisoning is ?
assistant
The correct answer is  Ans. is 'b' i.e., Physostigmine Atropine blocks cholinergic receptors. So, for atropine overdose, we require a drug that increases cholinergic action. Physostigmine increases the concentration of Ach. Physostigmine counteracts central (because it crosses BBB) as well as peripheral symptoms of atropine toxicity (other anticholinesterases like neostigmine and pyridostigmine counteract only peripheral symptoms as they cannot cross BBB) Physostigmine is the DOC.
