产品描述:
Pantoprazole-d6 is intended for use as an internal standard for the quantification of pantoprazole (Item No. 21345) by GC- or LC-MS. Pantoprazole is a proton pump inhibitor that inhibits H+/K+-ATPase activity in porcine gastric membrane vesicles with an IC50 value of 6.8 µM.{33533} It reduces basal gastric acid secretion in pylorus-ligated rats (ED50 = 1.3 mg/kg) and inhibits mepirizole-induced increases in gastric acid secretion in an anesthetized rat model of gastric fistula (ED50 = 0.8 mg/kg).{48468} Pantoprazole inhibits formation of mepirizole-induced duodenal lesions in rats (ED50 = 0.5 mg/kg). Formulations containing pantoprazole have been used in the treatment of gastroesophageal reflux disease (GERD) and hypersecretory conditions, including Zollinger-Ellison Syndrome.
