Tác dụng
Description: Mechanism of Action: Acetylcholine, a quaternary ammonium parasympathomimetic, is an endogenous neurotransmitter released from postganglionic parasympathetic nerves to produce peripheral actions corresponding to muscarine. It stimulates the parasympathetic nervous system causing vasodilation, cardiac depression, miosis, and decrease in intraocular pressure. Additionally, it also has actions that corresponds to nicotine producing stimulant action on skeletal muscle, autonomic ganglia, and adrenal medulla. Onset: Rapid. Duration: Approx 20 min.
