Having an action resembling that caused by stimulation of the parasympathetic nervous system.
A drug which stimulates the parasympathetic nervous system by making smooth muscle more tense, widening the blood vessels, slowing the heart rate, increasing the amount of sweat and saliva produced and contracting the pupil of the eye.
Having an effect (as from a drug) similar to that caused by stimulation of the parasympathetic nervous system (e.g., slowing the heart rate).
A drug that has the effect of stimulating the parasympathetic nervous system. The actions of parasympathomimetic drugs are cholinergic (resembling those of acetylcholine) and include stimulation of skeletal muscle, vasodilatation, depression of heart rate, increasing the tension of smooth muscle, increasing secretions, and constricting the pupil of the eye. They are used in the treatment of myasthenia gravis, glaucoma, and some heart and circulatory conditions (e.g. carbachol) and to restore intestinal and bladder function after surgery (e.g. bethenecol).
A drug that stimulates the parasympathetic nervous system. The actions of such drugs resemble those of acetylcholine. Those cholinergic actions include stimulation of musculoskeletal muscle, reduction in the heart rate, greater tension in involuntary (or smooth) muscle, increasing glandular secretions such as saliva, and constriction of the pupil of the eye. Myasthenia gravis, glaucoma, certain disorders of the cardiovascular system, and intestinal or bladder malfunction are among the conditions for which cholinergic drugs are prescribed.
A substance that emulates the outcomes produced by activating the parasympathetic nerves can be referred to as a parasympathomimetic agent.
