Pantoprazole is a proton pump inhibitor that decreases the amount of acid produced in the stomach. It is a prodrug.

Mechanism of action

Pantoprazole’s mechanism of action involves the permanent inhibition of proton pumps in the stomach, which are responsible for gastric acid production. It is a prodrug – in the acid environment of the parietal cells, Pantoprazole inhibits the H+, K+ ATPase of the coating gastric cells and gastric acid secretion is suppressed.
