Antacid: Generally histamine blockers or proton pump inhibitors are prescribed to halt acid production. However the diagnosis of antritis or gastritis should be made by a gastroenterologist. If an endoscopy is not done and the patient fails a trial of antacids, the patient should be endoscoped to make sure there is no other pathology or something else to treat, such as h. Pylori infection.
