WebSummary. Acetylcholinesterase inhibitors are a class of drugs that are used to treat myasthenia gravis. These drugs work by inhibiting the action of acetylcholinesterase, an enzyme that breaks down the neurotransmitter acetylcholine. Acetylcholine is responsible for mediating muscle contraction. By inhibiting its breakdown, acetylcholinesterase ... WebAcetylcholinesterase (AChE) is a cholinergic enzyme primarily found at postsynaptic neuromuscular junctions, especially in muscles and nerves. It immediately breaks down or hydrolyzes acetylcholine (ACh), a naturally occurring neurotransmitter, into acetic acid and choline. What are examples of acetylcholinesterase inhibitors?
