WebMechanism of action Cholinesterase inhibitors are competitive reversible antagonists of the enzyme cholinesterase which is responsible for the breakdown of acetylcholine at cholinergic synapses (ganglionic, postganglionic and neuromuscular) and the termination of cholinergic neurotransmission. Webanticholinesterase, any of several drugs that prevent destruction of the neurotransmitter acetylcholine by the enzyme acetylcholinesterase within the nervous system. Acetylcholine acts to transmit nerve impulses within the parasympathetic nervous system—i.e., that part of the autonomic nervous system that tends to induce secretion, to contract smooth …

Cholinesterase Inhibitors: From Molecular Mechanisms of Action …
WebFigure 2 below shows how a cholinesterase inhibitor (in this case, a nerve agent) attaches to the serine hydroxyl group on acetylcholinesterase. This prevents acetylcholine from … WebCholinesterase Inhibitors: Two groups of compounds, organophosphates and carbamates, share the same mechanism of action—inhibition of acetylcholinesterase. This enzyme normally is responsible for acetylcholine (neurotransmitter) destruction. WebAbstract Galantamine is a cholinesterase inhibitor with a dual mechanism of action. It is a reversible inhibitor of acetylcholine esterase and enhances the intrinsic action of acetylcholine on nicotinic receptors, leading to increased cholinergic neurotransmission in … regika ug
