Gastrec 40 mg Capsule
Omeprazole belongs under a class of drugs called proton pump inhibitors. Omeprazole blocks or inhibits gastric acid secretions. It reduces gastric acid secretion by inhibiting the enzyme system of hydrogen-potassium adenosine triphosphatase, which is regarded as the acid proton pump of the gastric parietal cells. Also called H+/K+ ATPase, the enzyme is responsible for the exchange of hydrogen and potassium ions during the formation of hydrochloric acid.
It is used in conditions where inhibition of gastric acid secretion may be beneficial including aspiration syndromes, dyspepsia, erosive esophagitis, gastro-esophageal reflux disease (GERD), benign gastric ulcer, duodenal ulcer, and hypersecretory conditions (e.g. Zollinger-Ellison syndrome).
