In brief: Antiacid stomach med

Zantac (ranitidine) is a histamine-2 (h2 blocker) which blocks acid secretion in the stomach.
It can be used for esophageal reflux (gerd) or other general hi acid states. It may be safer to use long-term than the other popular acid blockers (ppi's) e.g. Prilosec. Interestingly, since zantac is a histamine blocker it can also be used for 'allergy' or hives.
