What is the mechanism of action of omeprazole in suppressing gastric acid secretion and how does it inhibit proton pumps in the stomach lining to reduce acid production?
Omeprazole blocks the H+/K+ ATPase enzyme in stomach parietal cells, thereby halting gastric acid production at the source. This action directly inhibits proton pumps.
