Question

Physostigmine (Eserine ) is classified as a(n)

A. direct-acting cholinergic drug
B. reversible acetylcholinesterase inhibitor
C. irreversible acetylcholinesterase inhibitor
D. anticholinergic drug
E. ganglionic blocker

Answer 1

Physostigmine is a reversible acetylcholinesterase inhibitor that inactivates the enzyme acetylcholinesterase, preventing the breakdown of acetylcholine in the synapses.

Step-by-step explanation:

Physostigmine, also known as Eserine, is classified as a reversible acetylcholinesterase inhibitor. It inactivates the enzyme acetylcholinesterase, preventing the breakdown of the neurotransmitter acetylcholine in the synapses. This results in both muscarinic and nicotinic effects.
