Work Mechanism & Pharmacology
Patient Overview of Work Mechanism
Pantoprazole binds tightly to the acid pumps in your stomach, shutting down excess acid output to relieve acid reflux, heartburn, and gastritis.
Clinical Mechanism of Action (MoA)
Irreversible gastric proton pump inhibitor (PPI). In gastric parietal cell secretory canaliculi, protonation converts pantoprazole into a reactive sulfenamide that forms covalent disulfide linkages specifically with Cys813 and Cys822 of the H+/K+-ATPase alpha-subunit, achieving durable suppression of basal and meal-stimulated gastric acid production.
