Omeprazole effectively inhibits gastric acid secretion by targeting the H+/K+-ATPase proton pump. This medication is approved for severe gastroesophageal reflux disease (GERD) and Zollinger-Ellison syndrome, with recommendations for duodenal ulcer treatment.

Area of Science:

Pharmacology
Gastroenterology

Background:

Omeprazole is a substituted benzimidazole.
It specifically inhibits the H+/K+-ATPase enzyme, the proton pump responsible for gastric acid secretion.

Purpose of the Study:

To review the efficacy and applications of omeprazole in managing acid-related gastrointestinal disorders.

Main Methods:

Review of existing literature and clinical data on omeprazole's mechanism of action and therapeutic uses.

Main Results:

Omeprazole demonstrates potent inhibition of gastric acid secretion.
Approved indications include severe gastroesophageal reflux disease (GERD), refractory GERD, and Zollinger-Ellison syndrome.
Recommended as first-line therapy for duodenal ulcer disease.
