Rabeprazole (sodium salt)

Rabeprazole is a proton pump inhibitor that selectively and irreversibly inhibits the gastric H+/K+ ATPase (IC50 = 72 nM). It can be activated more rapidly and over a greater pH range than other proton pump inhibitors such as omeprazole (Cay-14880), lansoprazole (Cay-13627), and pantoprazole (Cay-21345). Rabeprazole (30 mg/kg) inhibits gastric acid secretion in pylorus-ligated rats and a rat model of gastric fistula. It also inhibits the growth of several strains of H. pylori in vitro (MIC50s = 1.57-3.13 µg/mL). Formulations containing rabeprazole have been used in the treatment of ulcers, pathological hypersecretory conditions, and gastroesophageal reflux disease (GERD).Formal Name: 2-[[[4-(3-methoxypropoxy)-3-methyl-2-pyridinyl]methyl]sulfinyl]-1H-benzimidazole, monosodium salt.
