Omeprazole

Overview

Basic Info

SummaryOmeprazole is a proton pump inhibitor (PPI) commonly used to treat gastrointestinal disorders including gastroesophageal reflux disease (GERD), peptic ulcers, and Zollinger-Ellison syndrome. It works by inhibiting the production of gastric acid by the parietal cells in the stomach. Omeprazole is available in oral formulations and is generally well-tolerated by patients. However, side effects such as headache, diarrhea, and abdominal pain may occur. Ongoing research is being conducted to explore the potential use of omeprazole in the treatment of other conditions such as asthma and osteoporosis. Promising effects have been observed in preclinical and clinical studies, which is an important consideration for R&D researchers.
