Pantoprazole is a specific inhibitor of the gastric proton pump (H+/K+- ATPase) in the parietal cell. It inhibits acid secretion by binding to the H+/K+- ATPase enzyme.
Pantoprazole is used to treat erosive esophagitis (damage to the esophagus from stomach acid caused by gastroesophageal reflux disease, or GERD).
