Pumaprazole is primarily used in the treatment of gastrointestinal disorders, particularly those related to excessive stomach acid production. It is effective in managing conditions such as gastroesophageal reflux disease (GERD), where it helps alleviate symptoms like heartburn and acid regurgitation. Additionally, it is utilized in the healing and prevention of gastric and duodenal ulcers, providing relief by reducing acid levels in the stomach. Pumaprazole is also prescribed in combination with antibiotics for the eradication of Helicobacter pylori, a bacterium linked to peptic ulcers. Its ability to inhibit proton pumps in the stomach lining makes it a key therapeutic agent in maintaining gastric health and improving patient comfort.
