Telenzepine dihydrochloride is a salt of Telenzepine. Telenzepine is a potent and selective muscarnic receptor antagonist reported to bind to mAChR M1 (Ki = 0.94 nM/L) and mAChR M2 (Ki = 17.8 nM/L) in a study utilizing rabbit and rat isolated superior cervical sympathetic ganglia. Evidence for selective inhibition of gastric acid secretion has been demonstrated in several animal model and in vitro experiments. Telenzepine was found to be 4-10 times more potent than Pirenzepine in these studies.
