Omeprazole (Cat.No:A000620) is a medication used in the treatment of gastroesophageal reflux disease, peptic ulcer disease, and Zollinger–Ellison syndrome. It is also used to prevent upper gastrointestinal bleeding in people who are at high risk. Omeprazole is a proton pump inhibitor and as such blocks the release of stomach acid.
