Used to treat and prevent peptic ulcers in the stomach and intestines by reducing the amount of acid produced in the stomach. Also used to manage conditions like gastroesophageal reflux disease (GERD) and heartburn by alleviating symptoms such as acid regurgitation and stomach discomfort. Helps in healing of erosive esophagitis and provides relief in Zollinger-Ellison syndrome, a condition where the stomach produces too much acid due to a tumor. Often prescribed for short-term use to allow ulcers to heal and to prevent their recurrence.
