Pantoprazole Pellets for Gastroesophageal Reflux Disease act as proton pump inhibitor that suppresses the final step in gastric acid production by forming a covalent bond to two sites of the ATPase enzyme system at the secretory surface of the gastric parietal cell. Pantoprazole Pellets are used to treat gastroesophageal reflux disease, a condition in which backward flow of acid from the stomach causes heartburn and injury of the food pipe. Pantoprazole Pellets are also used to treat conditions where the stomach produces too much acid, such as zollinger-ellison syndrome. Pantoprazole Pellets for Gastroesophageal Reflux Disease work by decreasing the amount of acid made in the stomach.
