How do acetylcholinesterase inhibitors work
WebCholinesterase inhibitors (ChEIs), also known as anti- cholinesterase, are chemicals that prevent the breakdown of the neurotransmitter acetylcholine or butyrylcholine. This increases the amount of the acetylcholine or butyrylcholine in the synaptic cleft that can bind to muscarinic receptors, nicotinic receptors and others. WebFeb 25, 2024 · Mechanism of Action. Cholinesterase inhibitors function by inhibiting cholinesterase from hydrolyzing acetylcholine into its components of acetate and choline'; this allows for an increase in the availability and duration of action of acetylcholine in neuromuscular junctions. The cholinesterase enzyme has two active sites: an anionic site ...
