title: Gastric inhibitory effects of CM57755. A new histamine H2 receptor antagonist.
abstract: The gastric inhibitory effects of CM57755, a new histamine H2 receptor antagonist, have been compared in ten healthy male volunteers with the actions of an equal dose of cimetidine and with placebo. The inhibitory effect of CM57755 was virtually identical with, and not significantly different from the effects of cimetidine on nocturnal gastric secretion of acid, while neither drug influenced the secretion of pepsin. Neither drug, administered in the evening, influenced the intragastric pH and acidity during the following day, from breakfast onwards. The therapeutic impact of the new drug is likely to resemble that of cimetidine and clinical application will depend on the safety profile.
