Esomeprazole strontium is a proton pump inhibitor. It suppresses gastric acid secretion by specific inhibition H+/K+ ATPase in the gastric parietal cell. The S- and R-isomers of omeprazole are protonated and converted in the acidic compartment of the parietal cell forming the active inhibitor, the achiral sulphenamide. By acting specifically on the proton pump, esomeprazole blocks the final step in acid production, thus reducing gastric acidity. The drug is indicated for the treatment of gastroesophageal reflux disease, reduction the risk of NSAID-associated gastric ulcer, eradication of H.pylori, and pathological hypersecretory conditions.

Sample Use Guides

In Vivo Use Guide

Active Duodenal Ulcer: 20 mg Once daily for 4 weeks. Some patients may require an addition 4 weeks. Gastric Ulcer: oral dose is 40 mg once daily for 4-8 weeks. Gastroesophageal Reflux Disease: The recommended adult oral dose for the treatment of patients with symptomatic GERD and no esophageal lesions is 20 mg daily for up to 4 weeks. The recommended adult oral dose for the treatment of patients with erosive esophagitis and accompanying symptoms due to GERD is 20 mg daily for 4 to 8 weeks.

Route of Administration: Oral

In Vitro Use Guide

Pretreatment of omeprazole (10-6 - 10-4M) dose-dependently inhibits neutrophil adherence and respiratory burst induced by H. pylori. These evidences imply that omeprazole may exhibit a beneficial effect on H. pylori-associated gastric mucosal damage caused by activated neutrophils.
