Esomeprazole is a proton pump inhibitor (PPI) medication used to treat conditions related to excess stomach acid. It works by reducing the amount of acid produced by the stomach.

Common uses of esomeprazole include:

• Gastroesophageal reflux disease (GERD): A condition where stomach acid flows back up into the esophagus, causing heartburn and other symptoms.
• Peptic ulcers: Sores in the lining of the stomach or duodenum.
• Zollinger-Ellison syndrome: A rare condition where the body produces too much stomach acid.
• Helicobacter pylori (H. pylori) infection: A bacteria that can cause peptic ulcers. Esomeprazole is often used in combination with antibiotics to eradicate this infection.
