What the antidote of atropine?

The antidote for atropine is physostigmine, a reversible inhibitor of the enzyme acetylcholinesterase. It increases the levels of acetylcholine at neurotransmitter junctions, counteracting the effects of atropine, which is an anticholinergic agent. Physostigmine is particularly effective in cases of atropine toxicity, helping to restore normal cholinergic activity in the body. However, it should be used with caution, as it can also lead to cholinergic side effects.
