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