[Action of some gastric antisecretory drugs on histamine H2-receptors (author's transl)].
A series of compounds endowed with gastric antisecretory activity were examined for their possible effects on histamine H2 receptors in different experimental conditions. The data obtained suggest that, apart from cimetidine, all the other compounds are devoid of antagonistic properties on H2 receptors. The inhibitory effect observed in some of the examined preparations is probably connected with unspecific actions.
