Famotidine is in the class of medications called histamine-2 (H2) blockers. Histamine is a chemical that naturally occurs and stimulates certain cells in the stomach to create acid. H2 blockers stop the action of histamine on the cells. As a result, it lessens the production of acid.
This is supplied as a tablet for oral use. Famotidine is available in the dosage forms of 20 mg and 40 mg. The Food and Drug Administration (FDA) has already approved this medication.
Famotidine works by stopping histamine H2 receptors that are found in the stomach lining. Histamine which is a natural body chemical usually binds to this receptor that causes the cells to create stomach acid. By stopping histamine H2 receptors, this medicine stops histamine from binding to them. This blocks the cells from making stomach acid which is made in the stomach as the usual part of the digestive course. Generally, the linings of the duodenum and stomach are protected by a layer that fights acid occurrence. On the other hand, if this layer is impaired or large quantities of stomach acid are formed, an ulcer may progress on the lining of the duodenum stomach. This is called a peptic ulcer.
In GERD, this medication lessens the production of stomach acid. It stops extra acid flowing back into the food pipe. It also permits the esophagus to heal in reflux esophagitis. By decreasing the amount of acid in the stomach and duodenum, this drug relieves the symptoms of indigestion.
