What is Famotidine Used For?
Famotidine belongs to a class of drugs known as histamine-2 (H2) blockers, which reduce the amount of acid produced by the stomach. This medication is indicated for the treatment of several conditions, including:
- Gastroesophageal Reflux Disease (GERD): A condition where stomach acid flows back into the esophagus, causing symptoms like heartburn and discomfort.
- Peptic Ulcer Disease: Sores that develop on the lining of your stomach and the upper portion of your small intestine.
- Zollinger-Ellison Syndrome: A rare disorder characterized by excessive stomach acid production due to tumors in the pancreas or upper part of the small intestine.
How Does Famotidine Work?
Famotidine works by competitively inhibiting the action of histamine at the H2 receptors of the gastric parietal cells, leading to a reduction in gastric acid secretion. This action helps in healing and preventing ulcers in the stomach and intestines and reduces symptoms of GERD.
