Pantiprozole is a medication classified as a proton pump inhibitor (PPI) that is used to reduce stomach acid production. It is commonly prescribed for conditions such as gastroesophageal reflux disease (GERD), peptic ulcers, and Zollinger-Ellison syndrome. By inhibiting the proton pumps in the stomach lining, it helps alleviate symptoms related to excessive acidity and promotes healing of the esophagus and stomach lining. Like other PPIs, it may have potential side effects and should be used under medical supervision.
