Over 30 Years of Omeprazole.

BACKGROUND

In the last 3 decades, omeprazole has proved its mettle in managing acid peptic diseases (APDs). It has established itself as the first line of therapy for duodenal and gastric ulcers, gastroesophageal reflux disease (GERD), ulcers due to nonsteroidal anti-inflammatory drugs (NSAID), and Zollinger-Ellison syndrome (ZES).

OBJECTIVES

The purpose of this literature review is to assess the effectiveness of omeprazole as compared to the other proton pump inhibitors (PPIs) currently in use and its safety and efficacy in special populations, including the pediatric and geriatric populations.

RESULTS

Omeprazole was found to be the most effective PPI in the management of APDs due to its rapid action, good antioxidant effects, and effectiveness against nocturnal acid breakthroughs. Its safety and tolerance have been proved in various randomized controlled trials.

CONCLUSION

Omeprazole is the prototypical drug in the management of APDs and has withstood the test of time. After 3 decades, omeprazole remains the drug of choice in managing APD.
