Famotidine (Brand Name: Pepcid)
Famotidine blocks the action of histamine on stomach cells, and reduces the production of acid by the stomach. Famotidine is useful in promoting the healing of stomach and duodenal ulcers and in reducing ulcer pain. Famotidine has been effective in preventing recurrence of ulcers when given in low doses for prolonged periods of time. Famotidine also is used for treating heartburn and in healing ulceration and inflammation of the esophagus (esophagitis) resulting from acid (gastroesophageal reflux disease or GERD).
