Ranitidine is an oral medication approved by the U.S FDA since 1984 for the treatment of conditions like:

  • Zollinger-Ellison Syndrome- a condition in which the stomach produces too much acid
  • Gastroesophageal reflux (GERD)
  • Prevention of stomach and intestinal ulcers

Ranitidine also treat other condition in which the acid in the stomach flows back up to the esophagus causing heartburn. It also heals acid –related damage to the lining of the esophagus or erosive esophagitis. Ranitidine is an H-2 (histamine -2) blocker. It works by blocking the production of acid produce by the acid-producing cell in the stomach. Histamine is a naturally occurring chemical in the body. It stimulates the acid-producing cells to produce acid. Ranitidine inhibits the actions of histamine thus reducing the production of the acid that can cause damages to the esophagus, stomach and duodenum.

Ranitidine is available as a prescription drug and as a brand name drug. The generic drug cost a lot cheaper than the brand names. It may be used as a part of a combination therapy.
