What Are Acetylcholinesterase Inhibitors Used For. Cholinesterase inhibitors (acetylchlinesterase inhibitors) are medications that block the breakdown acetylcholine (a neurotransmitter), and that block the action of acetylchlinesterase in the body. Cholinesterase inhibitors block the action of the enzyme cholinesterase, which is responsible for breaking down acetylcholine.

Cholinesterase inhibitors (acetylchlinesterase inhibitors) are medications that block the breakdown acetylcholine (a neurotransmitter), and that block the action of acetylchlinesterase in the body. These inhibitors are in general classified into three categories which are reversible (the action can be reversed),. An enzyme called acetylcholinesterase breaks down acetylcholine.
