Ranitidine is a medicine that is prescribed to treat certain ulcers of the stomach and intestines and prevents them from coming back after they have healed.
This medication can be used to treat certain stomach and throat problems such as Zollinger-Ellison Syndrome, Gastroesophageal Reflux Disease (GERD), and Erosive Esophagitis.
The medicine belongs to a class of drugs known as histamine H2 blockers and has an active drug called Ranitidine. It inhibits histamine H2 receptors located on the surface of parietal cells in the stomach lining and the blockade leads to the reduction of acid produced by the stomach, thereby treating conditions where excessive gastric acid secretion causes certain symptoms such as heartburn, acid reflux, and peptic ulcers.
The medicine may be prescribed to treat symptoms more than those mentioned above.
As of April 2020, this medication has been withdrawn from the US market due to safety risks. An investigation found certain ranitidine products contaminated with a carcinogen named N-nitrosodimethylamine. However, in Canada, Ranitidine is available.
