Oxyphencyclimine binds the muscarinic acetylcholine receptor. It may block all three types of muscarinic receptors including M-1 receptors in the CNS and ganglia, M-2 receptors in the heart (vagus) and M-3 receptors at the parasympathetic NEJ system. The muscarinic acetylcholine receptors mediate various cellular responses, including inhibition of adenylate cyclase, breakdown of phosphoinositides and modulation of potassium channels through the action of G proteins. Oxphencyclimine inhibits vagally mediated reflexes by antagonizing the action of acetylcholine. This in turn reduces the secretion of gastric acids in the stomach.
Enhanced effect with concurrent admin of other drugs with antimuscarinic properties and MAOIs. May affect absorption of other drugs. Antagonistic effect with parasympathomimetics.
