tridihexethyl

Tridihexethyl is a synthetic anticholinergic agent which was marketed under the brand name Pathilon as an adjunct in the treatment of peptic ulcer disease. However, it is no longer available in the US market. Tridihexethyl may block all three types of muscarinic receptors including M-1 receptors in the CNS and ganglia, M-2 receptors in the heart, and M-3 receptors. The muscarinic acetylcholine receptors mediate various cellular responses including inhibition of adenylate cyclase, the breakdown of phosphoinositides, and modulation of potassium channels through the action of G proteins. Tridihexethyl inhibits vagally mediated reflexes by antagonizing the action of acetylcholine. This, in turn, reduces the secretion of gastric acids in the stomach. Tridihexethyl was also examined for effect on patients with acquired nystagmus where four out of six patients showed improvement, but due to the profile usage of Tridihexethyl to treat nystagmus was limited. — NCATS
