Pirenzepine Dihydrochloride is an analogue of Pirenzepine. Pirenzepine is a selective antagonist for the mAChR M1 (M1 muscarinic receptor) and is reported to block presynaptic mAChR M1 as well as some reported inverse agonist activity. A study investigating the pharmacological characterization of the muscarinic receptors associated with ACh-induced pulmonary vasodilation in a rabbit model of pulmonary hypertension determined the IC50 to be 2.51x10-7M. Additional research studies have investigated the role of Pirenzepine in the pathophysiology of myopia. Other mAChR M1 antagonists offered include Telenzepine (sc-204332).
