Mechanism of action

Pantoprazole is a proton pump inhibitor (PPI) that irreversibly binds to and inactivates the H+/K+-ATPase enzyme on the secretory surface of gastric parietal cells. This blocks the final step of gastric acid production, reducing intragastric pH and providing rapid acid suppression. The IV formulation allows for direct systemic delivery in patients unable to take oral medication.
