Frequently Asked Questions (FAQs):
1) How is Rantac different from Antacid?
Ans: Both Rantac and Antacid provide relief in acidity and heartburn, but the mode of operation of the two medicines differs. Rantac acts by blocking H2 Histamine receptors whereas Antacid acts by neutralizing the acid in the stomach. Rantac is prescribed for medical conditions in which the stomach produces too much acid or acid production in the stomach needs to be stopped due to medical reasons. Antacids are for temporary relief for acidity due to overeating. Antacid tablets or powder sachets can be purchased over the counter from most of the chemist shops.

2) How is Rantac different from Omeprazole?
Ans: Omeprazole also inhibits acid production in the stomach but in a manner different from Ranitidine. Whereas Ranitidine inhibits acid production in the stomach by blocking the H2 receptor, Omeprazole inhibits acid production by inhibiting proton pump action. Omeprazole belongs to the category of proton pump inhibitor whereas Rantac (Ranitidine) belongs to the category of H2 blocker. Proton pumps are found in the cells lining the stomach and secrete acid. Both the drugs have their set of own advantages, disadvantages, interactions and limitations and it is up to the doctor to choose acid inhibiting mechanism as per the medical condition of the patient.
3) What are the other drugs that belong to the category of H2 Blockers?
