In dogs, the effect of atropine on gastric acid secretion induced by food, mechanical stimuli, and histamine involved a complete block of the acid secretion but left the gastric secretory effect of histamine unaffected. Atropine caused about a twofold increase in duration of histamine-evoked acid secretion and a rise of the intragastric acidity in all parts of the stomach.
