Pantoprazole is a proton pump inhibitor drug that inhibits gastric acid secretion. It works on gastric parietal cells to irreversibly inhibit (H+/K+)-ATPase function and suppress the production of gastric acid. It was first sold in 1994 in Germany and became avaliable as a generic medication in 2010.
Pantoprazole is used to treat conditions in which too much acid is produced by the stomach such as Zollinger-Ellison syndrome and to prevent intestinal and stomach ulcers in people at risk due to continuous use of non-steroidal anti-inflammatory pain-killer drugs (NSAIDs) such as ibuprofen.
