Donetidine is a potent and long acting histamine H2-receptor antagonist with no H1-receptor antagonist activity. It is a highly basic drug with several amine groups. Donetidine stimulates the release of histamine when given by rapid intravenous infusion to dogs. Symptoms such as vasodilation, watering eye and nose, salivation and collapse, well known indicators of histamine release seen after administration of donetidine.
