Description and Uses

Rebeprazole sodium was launched as Pariet in Japan, its first market, for the treatment of peptic ulcers including gastric and duodenal ulcers. From 4-chloro- 2,3-dimethylpyridine N-oxide, a six step synthesis allows access to the basic skeleton after successive condensations. Rabeprazole, a structural analog of Omeprazole, the first compound to have been marketed in this class up to now, is reported to be a more potent inhibitor of gastric H+/K+-adenosine triphosphate (ATPase) ; a common mechanism of action of this chemical class involves the conversion at low pH to a reactive sulphonamide that itself binds to cysteine residues located on the enzyme. Moreover, rabeprazole showed an antibacterial activity against Helicobacter Pylori, with a MIC90 of 1.56 μg/ml.
Rebeprazole sodium has a faster onset of action compared with omeprazole, but a shorter duration of action, being extensively and rapidly metabolized in several animal species. In clinical studies in patients with gastric ulcers, 10 and 20 mg rabeprazole sodium once-daily significantly inhibited basal and stimulated acid output. Rabeprazole is awaiting registration in the US for treatment of gastrooesophageal reflux disease (GORD) and other pathologic hypersecretory conditions including Zollinger-Ellison syndrome.

Rebeprazole sodium is a partially reversible gastric proton pump inhibitor. It belongs to a national second-class drug that can be used for the treatment of gastric ulcers. It can treat peptic ulcer, gastroesophageal reflux disease, zollinger-ellison syndrome and other diseases. This compound has the effects of anthelminthic, antiseptic, and expectorant. As an antibacterial and antifungal agent, it is effective against gram-positive and gram-negative bacteria, yeast and fungi.
