Omeprazole, a medication commonly known by its brand name Prilosec among others, is a proton pump inhibitor (PPI) that decreases the amount of acid produced in the stomach. It is used to treat symptoms of gastroesophageal reflux disease (GERD) and other conditions involving excessive stomach acid such as Zollinger-Ellison syndrome. The 40mg dosage is typically prescribed for more severe cases or when lower doses have not been effective.

- Duodenal Ulcers: It is effective in healing duodenal ulcers by decreasing acid production, allowing the ulcers to heal.
- Zollinger-Ellison Syndrome: For individuals with Zollinger-Ellison syndrome, which involves excessive acid production due to a gastrin-secreting tumor, omeprazole can help manage the excessive acid production.
- Helicobacter pylori Eradication: Omeprazole, in combination with antibiotics, is used to treat infections caused by H. pylori bacteria, which can lead to peptic ulcers.
