Rabeprazole is one of the latest proton-pump inhibitors used for treatment of several gastrointestinal disorders. For therapeutic applications, rabeprazole has been administered as a mixture of R-(+) and S-(-) enantiomers. Owing to pharmacological and toxicological differences between stereoisomers, chiral recognition has now become an integral part of drug research and development. A simple and rapid liquid chromatographic method for enantioselective separation and determination of R-(+) and S-(-) enantiomers of rabeprazole in bulk drug and pharmaceutical formulations was developed...

PURPOSE: Clinically relevant pharmacokinetic interactions exist between gastric acid-reducing agents and certain weakly basic drugs that rely on acidic environments for optimal oral absorption. In this study, we examine whether the administration of betaine hydrochloride under fed conditions can enhance the absorption of atazanavir, an HIV-1 protease inhibitor, during pharmacologically-induced hypochlorhydria. METHODS: In this randomized, single-dose, 3 period, crossover study healthy volunteers received ritonavir-boosted atazanavir (atazanavir/ritonavir 300/100 mg) alone, following pretreatment with the proton pump inhibitor rabeprazole (20 mg twice daily), and with 1500 mg of betaine HCl after rabeprazole pretreatment...

Both proton pump inhibitors (PPIs) and clopidogrel are widely prescribed in the Asia-Pacific population. PPIs are the mainstay therapeutic agents for prophylaxis against aspirin gastropathy and for ARDs (Acid Related Disorders) including gastroesophageal reflux disease (GERD). They are also co-prescribed with oral anticoagulant agents (OAAs)and with dual-antiplatelet therapy (DAPT) for the treatment and prevention of gastrointestinal (GI) bleeding. Clopidogrel belongs to the drug class of thienopyridines, and is currently the most widely prescribed OAA either alone or in combination with aspirin...

Rabeprazole is a novel benzimidazole proton pump inhibitor used for the treatment of gastrointestinal disorders. It is a chiral molecule that gives rise to the possibility of stereoselective pharmacokinetics. To investigate this phenomenon, a rapid and sensitive chiral assay based on supercritical fluid chromatography tandem mass spectrometry was developed and applied to the determination of (R)-rabeprazole and (S)-rabeprazole in dog plasma. Sample preparation involved protein precipitation with acetonitrile after the addition of (R)-lansoprazole as internal standard...

Patients with gastroesophageal reflux disease (GERD) are routinely prescribed one of the six FDA approved proton pump inhibitors (PPI). All of these PPI are inhibitors of CYP2C19 enzyme to varying degrees. The phenotype pantoprazole-(13)C breath test (Ptz-BT) was used to identify patients who are poor metabolizers (PM) and the extent of phenoconversion of CYP2C19 enzyme activity caused by four PPI (omeprazole, esomprazole pantoprazole and rabeprazole) in 54 newly diagnosed GERD patients prior to initiating randomly selected PPI therapy and 30 d after PPI therapy...

Proton pump inhibitors (PPIs) at low doses can effectively prevent gastrointestinal bleeding due to aspirin and are widely used in Japan for gastroprotection in patients taking anti-platelet agents. We examined the influence of different PPIs at low doses administered concomitantly or separately on anti-platelet functions of clopidogrel. In 41 healthy Japanese volunteers with different CYP2C19 genotypes who took clopidogrel 75 mg in the morning alone, or with omeprazole 10 mg, esomeprazole 10 mg, lansoprazole 15 mg, or rabeprazole 10 mg, either concomitantly in the morning or separately in the evening, we measured the inhibition of platelet aggregation (IPA, %) using VerifyNow P2Y12 assay at 4 h after the last clopidogrel dose on Day 7 of each regimen...

BACKGROUND: Vonoprazan (VPZ)-based triple therapy has been reported to have greater efficacy than a proton pump inhibitor (PPI)-based triple therapy for Helicobacter pylori (H. pylori) eradication. However, because VPZ is more expensive than PPIs such as rabeprazole (RPZ), economic evaluation is essential. METHODS: We performed a retrospective study on 209 patients who underwent first-line eradication of H. pylori infection in Fuyoukai Murakami Hospital from 1 March 2015 to 31 March 2016...

BACKGROUND/AIMS: Studies on the therapeutic efficacy of proton pump inhibitors (PPIs) in patients with gastroesophageal reflux disease (GERD) have been recently published. In most of these studies, comparison of only two PPIs have been made. There are few studies on the comparison of four or more PPIs. We aimed to compare the acid inhibitory effects of esomeprazole 40 mg, rabeprazole 20 mg, lansoprazole 30 mg, and pantoprazole 40 mg on days 1 and 5 of treatment in patients with GERD, who were extensive metabolizers in regard to the CYP2C19 genotype...

The use of deuterated drug bioisosteres to obtain superior pharmacokinetic properties or to investigate biotransformations at the molecular level is a growing field of pharmaceutical research. This work presents a NMR study on the deuteration of three structurally related antisecretory proton-pump inhibitors, the sodium salts of esomeprazole, 1, pantoprazole, 2, and rabeprazole, 3. It has been found that the methylene adjacent to the sulfinyl group displays stereoselective deuteration when the sodium salts of these products are dissolved at room temperature in D2O or CD3OD, a process that also occurs very efficiently in DMSO-d6 (a solvent considered non-deuterating) if a catalytic amount of NaOH is added...

BACKGROUND & AIMS: Hepatic encephalopathy (HE) is a serious complication of cirrhosis and is associated with gut dysbiosis. Proton pump inhibitors (PPIs), frequently prescribed to patients with cirrhosis, can contribute to small-bowel bacterial overgrowth. We investigated whether PPI predisposes patients with cirrhosis to HE using a large database of patients. METHODS: We performed a case-control study nested within a sample of Taiwan National Health Insurance beneficiaries (n = 1,000,000), followed up longitudinally from 1998 through 2011...
