NCIt definition : A synthetic tertiary amine and antimuscarinic agent with antispasmodic and antisecretory
activities. Oxyphencyclimine binds to and blocks the muscarinic receptor on smooth
muscle. This agent has a direct relaxing effect on smooth muscle and therefore prevents
spasms in the muscles of the gastrointestinal tract, inhibits gastrointestinal propulsive
motility, decreases gastric acid secretion and controls excessive pharyngeal, tracheal
and bronchial secretion.;
