Parasympathomimetic drug

A parasympathomimetic drug, sometimes called a cholinomimetic drug[1] or cholinergic receptor stimulating agent,[2] is a substance that stimulates the parasympathetic nervous system (PSNS).[3][2] These chemicals are also called cholinergic drugs because acetylcholine (ACh) is the neurotransmitter used by the PSNS.[1][4] Chemicals in this family can act either directly by stimulating the nicotinic or muscarinic receptors (thus mimicking acetylcholine), or indirectly by inhibiting cholinesterase, promoting acetylcholine release, or other mechanisms.[5] Common uses of parasympathomimetics include glaucoma, Sjögren syndrome and underactive bladder.[6]

Some chemical weapons such as sarin or VX, non-lethal riot control agents such as tear gas, and insecticides such as diazinon fall into this category.

Parasympathomimetics are a group of drugs that act either by directly stimulating the muscarinic receptor, for example pilocarpine, or by inhibiting the enzyme acetylcholinesterase, which hydrolyses the acetylcholine in the synapse.
