    Ranitidine n cimetidine r antacids as well as antihistamine because these were designed to prevent the interaction of histamine with receptors present in the stomach walls n u know that histamine is responsible for the production of pepsin n HCl in stomach. Hence these also control hyperacidity.

    Avantika Tayal 5 years, 10 months ago

    Ranitidine is a antihistamine which works as a antacid(ncert mein likha hai) it has same effect as that of antacid the only difference is its receptors are different and so is considered somewhat different from antacid....

    Ranitidine is in a group of drugs called histamine-2 blockers. Ranitidine works by reducing the amount of acid your stomach produces. Brompheniramine is an antihistamine that reduces the effects of natural chemical histamine in the body. ... So Ranitidine and Cimetidine are antihistamine antacids.
