Proton Pump Inhibitors irreversibly block the H+/K+ ATPase enzyme system (the 'proton pump') in gastric parietal cells. This action profoundly suppresses stomach acid secretion, providing symptomatic relief and allowing for the healing of damaged esophageal and stomach tissue in acid-related gastrointestinal disorders.
Verdict
