Pantoprazole Sodium Sesquihydrate Eq. to Pantoprazole 40mg is a medication primarily used to reduce stomach acid production in conditions such as gastroesophageal reflux disease (GERD), gastric ulcers, and Zollinger-Ellison syndrome. Pantoprazole is a proton pump inhibitor (PPI) that works by inhibiting the proton pumps in the stomach lining, which are responsible for producing gastric acid. This leads to a decrease in acid levels, providing relief from symptoms such as heartburn, acid reflux, and esophageal irritation. The 40mg dosage is typically prescribed for more severe acid-related conditions and is taken once daily, usually before meals. Pantoprazole helps in healing ulcers and preventing their recurrence while offering long-term symptom management.
