Ranitidine is a selective H2 antihistaminic. This drug blocks gastric secretion, cardiac stimulation, and bronchial relaxation. Zantac is also used in the treatment of gastric and duodenal ulcers, hypersecretory conditions like Zollinger-Ellison syndrome and systemic mastocytosis and erosive esophagitis. Zantac is highly selective in action. Zantac has no effect on H1 mediated responses or on action of other transmitters or autocoids. It blocks all the phases of gastric secretion. The secretory responses to histamine are attenuated. Zantac amplifies the responses to secretagogues. It reduces the volume of acid, pepsin content and intrinsic factor secretion. This does not interfere with vitamin B12 absorption.
