The effects of HSR-902, an antimuscarinic agent, on development of various gastric and duodenal lesions, gastric secretion, pupil size and salivation in rats were compared with those of pirenzepine•2HCl (pirenzepine, antiulcer agent) and timepidium bromide (timepidium, antispasmodic). 1) HSR-902 (10 ?? 100 mg/kg), given orally, dose-dependently inhibited the developments of gastric lesions induced by water-immersion stress, aspirin, indomethacin, serotonin and reserpine and duodenal lesions induced by cysteamine and mepirizole. The activities of HSR-902 were almost equal or somewhat more potent than those of pirenzepine, and they were more potent than those of timepidium. 2) HSR-902 (30 and 100 mg/kg, p.o.), when examined using pylorus-ligated preparations, dose-dependently inhibited the gastric acid output, pepsin output, and gastric acid and pepsin concentrations, but did not inhibit the gastric volume (HSR-902, in a higher dose, slightly increased the gastric volume.). Pirenzepine (100 mg/kg, p.o.), like atropine sulfate, inhibited the gastric volume, acid output and pepsin output, but did not inhibit the gastric acid and pepsin concentrations. Timepidium (100 mg/kg, p.o.), however, hardly influenced these parameters except for increasing the gastric volume. 3) HSR-902 (100 mg/kg, p.o.) induced the mydoriasis and inhibited the pilocarpine-induced salivation, and its activities were less potent than those of pirenzepine. These results suggest that HSR-902 is a promising agent for the treatment of peptic ulcer.
