The prescribed omeprazole oral capsule functions as a delayed-release medication. This means its release is slowed down until it has passed through the stomach, preventing its deactivation by stomach acids.
Why it’s used
Omeprazole is utilized to address conditions instigated by excessive acid production in the stomach, including:
- Gastroesophageal reflux disease (GERD)
- Erosive esophagitis (damage to the esophagus caused by acid)
- Gastric (stomach) ulcers or duodenal ulcers (which occur in the first part of the small intestine)
- Zollinger-Ellison syndrome
- Stomach infections caused by Helicobacter pylori bacteria.
Furthermore, this medication might be employed as part of a combination therapy, necessitating its use alongside other medications.
How it works
Omeprazole is classified under a group of medications known as proton pump inhibitors (PPIs). A drug class encompasses medications that function similarly and are frequently employed to treat similar ailments.
The mechanism of action of omeprazole involves reducing the quantity of acid produced in your stomach. It achieves this by obstructing a system within the stomach cells called the proton pump. This pump is responsible for the final phase of acid production. By blocking the proton pump, omeprazole reduces the production of acid in the stomach, thereby alleviating symptoms.
