Which of the following is a ‘Protein Pump Inhibitor’?
Correct Answer: Omeprazole
Description: Omeprazole is a proton pump inhibitor, it inhibits gastric acid secretion. It inhibits the H+ K+ ATPase enzyme in the apical membrane of parietal cells, thereby reducing acid secretion. Acid secretion resumes only when new H+ K+ ATPase is formed. It is the treatment of choice for peptic ulcer, gastroesophageal reflux disease, and Zollinger Ellison syndrome.
