parasympathomimetic
Rest-and-digest promoter
Parasympathomimetic describes drugs or substances that mimic the effects of the parasympathetic nervous system—the branch that slows heart rate, stimulates digestion, and promotes "rest and digest" functions.
These agents work by activating the same receptors as acetylcholine or by inhibiting its breakdown: Pilocarpine is a parasympathomimetic used to treat glaucoma.
The noun form refers to such a drug.
