Parasympathomimetic drug



A parasympathomimetic drug is a drug or poison that acts by stimulating or mimicking the parasympathetic nervous system (PSNS). These chemicals are also called cholinergics because acetylcholine (ACh) is the neurotransmitter used by the PSNS. Chemicals in this family can act either directly by stimulating the nicotinic or muscarinic receptors, or indirectly by inhibiting cholinesterase, promoting acetylcholine release, or other mechanisms. [1]

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.

Direct-acting

These act by stimulating the nicotinic or muscarinic receptors.

Indirect-acting

Indirect acting parasympathomimetic drugs may be either reversible cholinesterase inhibitors, irreversible cholinesterase inhibitors or drugs that promote ACh release or Anti-adrenergic. The latter inhibits the antagonistic system, the sympathetic nervous system.
