title: [Inhibition of pentagastrin-stimulated gastric secretion by ranitidine (author's transl)].
abstract: The dose-effect relationship of ranitidine, a recently developed selective histamine H2 receptor antagonist was tested on six healthy subjects after oral administration. Ranitidine gave dose-dependent inhibition of pentagastrin-stimulated acid secretion. Half-maximal inhibition occurred at 75 mg. The antisecretory effect was still demonstrable five hours after oral intake. The drug is thus more powerful and has more lasting antisecretory action, even after oral intake, than cimetidine.
