Used to treat conditions involving excess stomach acid, such as gastroesophageal reflux disease (GERD), peptic ulcers, and Zollinger-Ellison syndrome. It helps reduce acid production in the stomach, relieving symptoms like heartburn and acid regurgitation. Often prescribed for short-term healing of erosive esophagitis and used in combination with antibiotics to eradicate Helicobacter pylori, a bacterium linked to stomach ulcers. Also used to prevent NSAID-induced gastric ulcers in patients on long-term anti-inflammatory therapy. Available in oral formulations including capsules and orally disintegrating tablets.
