1. How It Works

As a proton pump inhibitor, omeprazole works by suppressing the secretion of stomach acid. It blocks the action of the proton pump, an enzyme system located on the surface of the gastric parietal cells. Omeprazole blocks the last step in the process of stomach acid production, and it starts to work within one hour after it is taken by mouth. The full effect of the medicine is normally felt within two hours, and omeprazole can continue to inhibit stomach acid secretion for up to three days after a single dose. Once omeprazole is discontinued, the patient's stomach acid levels will return to their baseline after three to five days.
