WebAcetylcholinesterase Inhibitor. AChE inhibitor (generally referred to as cholinesterase inhibitor) is a chemical that binds to the enzyme, cholinesterase, and prevents it from breaking down the neurotransmitter, ACh. With toxic doses, the result is that excessive levels of the ACh build up in the synapses and neuromuscular junctions and glands. WebJan 19, 2024 · Acetylcholinesterase (AChE) is a cholinergic enzyme primarily found at postsynaptic neuromuscular junctions, especially in muscles and nerves.
