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. WebMay 13, 2024 · You can develop pseudocholinesterase deficiency as a result of conditions that cause you to make less of the pseudocholinesterase enzyme. These conditions include chronic infections, kidney or liver disease, malnutrition, severe burns, cancer, or pregnancy. Certain medications also can reduce production of the enzyme.
