Description

Atropine is an antimuscarinic agent which competitively antagonises acetylcholine at postganglionic nerve endings, thus affecting receptors if the exocrine glands, smooth muscle, cardiac muscle and the central nervous system.

Hyoscyamine inhibits specifically the actions of acetylcholine on structures innervated by postganglionic cholinergic nerves and on smooth muscles that respond to acetylcholine but lack cholinergic innervation. Hyoscyamine inhibits gastrointestinal propulsive motility and decreases gastric acid secretion. It also controls excessive pharyngeal, tracheal and bronchial secretions.
