Omeprazole 20 Capsule is a medication classified as an anti-ulcer agent, primarily used to alleviate conditions associated with excessive stomach acid production. It is commonly prescribed for the treatment of stomach and duodenal ulcers, gastroesophageal reflux disease (GERD), and Zollinger-Ellison syndrome, all of which are attributed to elevated levels of stomach acid.
- Omeprazole is used to treat various conditions including ulcers in the stomach and duodenum, GERD, Zollinger-Ellison syndrome, and erosive esophagitis.
- It functions as a gastric acid secretion inhibitor, blocking the hydrogen-potassium-adenosine triphosphatase (H+/K+ ATPase) enzyme system in gastric parietal cells, thus reducing acid secretion.
- Omeprazole is available in oral and intravenous formulations, with dosage varying depending on the condition being treated.
- Common oral doses range from 20-40 mg once daily for conditions like ulcers and GERD, with variations for different patient populations and severity of the condition.
- IV injection is recommended for specific conditions like prophylaxis of acid aspiration and in patients where oral medication is inappropriate.
- Omeprazole is generally well-tolerated, with side effects such as nausea, abdominal colic, paresthesia, dizziness, and headache being mild and transient.
- It is classified as a pregnancy category C medication by the US FDA, but studies suggest no negative effects on pregnancy or the health of the fetus/newborn child.
- Precautions include ruling out gastric cancer before treatment initiation in suspected cases of gastric ulcer.
- Storage instructions include keeping the medication below 30°C, away from light and moisture, and out of reach of children.
