Omeprazole-d3

Omeprazole-d3 is intended for use as an internal standard for the quantification of omeprazole (Cay-14880) by GC- or LC-MS. Omeprazole is an inhibitor of gastric H+/K+ ATPase (IC50 = 1.1 µM for the pig ATPase). It is a racemic mixture of esomeprazole (Cay-17303) and (R)-omeprazole (Cay-18874). Omeprazole (100 µM) decreases zymosan-induced oxygen free radical production in isolated human neutrophils. It is active against 17 strains of H. pylori (MIC50s = 12.5-50 µg/ml). It decreases histamine-induced acid secretion in dogs (ED50 = 0.35 µmol/kg). Formulations containing omeprazole have been used in the treatment of duodenal and gastric ulcers, gastroesophageal reflux disease, and erosive esophagitis.Formal Name: 6-methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridinyl)methyl]sulfinyl]-1H-benzimidazole-4,5,7-d3.
