Efficacy and Safety Profile of Z-215 (Azeloprazole Sodium), a Proton Pump Inhibitor, Compared to Rabeprazole Sodium in Patients with Reflux Esophagitis: A Phase II, Multicenter, Randomized, Double-Blind, Comparative Study
Conclusions Z-215 was as effective and well-tolerated as 10 mg RPZ in the treatment of RE in this selected population. CYP2C19 genotype status may not affect the efficacy and safety of Z-215. There were no clear dose-response effects between Z-215 doses in the endoscopic healing of RE. These findings suggest that Z-215 may be one option for the initial treatment of RE.

Pharmacokinetics and Pharmacodynamics of Azeloprazole Sodium, a Novel Proton Pump Inhibitor, in Healthy Japanese Volunteers.
Abstract The pharmacokinetics (PK) and pharmacodynamics (PD) of proton pump inhibitors differ among cytochrome P450 (CYP) 2C19 genotypes. Therefore, we developed azeloprazole sodium (Z-215), a novel proton pump inhibitor, whose metabolism is not affected by CYP2C19 activity in vitro. However, the PK and PD of azeloprazole sodium have not been evaluated in Japanese subjects. We conducted an open-label, crossover study in healthy Japanese male volunteers to evaluate the plasma concentration and intragastric pH with respect to CYP2C19 genotype after repeated administration of 10, 20, and 40 mg azeloprazole s...

In Brief: PPIs and Torsades de Pointes
Date: December 5, 2016 Issue #:  1509Summary:  Therapeutics (AZCERT) has recently added the proton pump inhibitors (PPIs) omeprazole (Prilosec, and others), esomeprazole (Nexium, and others), lansoprazole (Prevacid, and others), and pantoprazole (Protonix, and generics) to its lists of Drugs with Conditional Risk of Torsades de Pointes (TdP) and Drugs to Avoid in Patients with Congenital Long QT Syndrome.1PPIs do not directly cause prolongation of the QT interval, but they can cause hypomagnesemia, which is often accompanied by hypocalcemia and hypokalemia and can result in cardiac...

Do proton pump inhibitors cause dementia?
A great deal of media attention has been given to a recently-published study that concluded that the prevalence of dementia was significantly greater in patients who had been regularly taking a proton pump inhibitor (PPI) including omeprazole (Prilosec), esomeprazole (Nexium), lansoprazole (Prevacid), pantoprazole (Protonix) or rabeprazole (Aciphex). The article was reported by many media outlets in stories with titles ranging from “Can Common Heartburn Drugs Raise Risk for Dementia?” and “Proton Pump Inhibitors Linked to Dementia” the former being a title that perhaps distorts the actual study findings misleading ...

Development and validation of dissolution testings in acidic media for rabeprazole sodium delayed-release capsules.
Authors: Tan Y, Si X, Zhong L, Feng X, Yang X, Huang M, Wu C Abstract Rabeprazole sodium (RAB) dissolved in acidic media is accompanied by its degradation in the course of dissolution testing. To develop and establish the accumulative release profiles of ACIPHEX(®) Sprinkle (RAB) delayed-release capsules (ACIPHEX(®) Sprinkle) in acidic media using USP apparatus 2 (paddle apparatus) as a dissolution tester, the issues of determination of accumulative release amount of RAB in these acidic media and interference of hydroxypropylmethyl cellulose phthalate were solved by adding appropriate hydrochloric acid (...

Stomach specific polymeric low density microballoons as a vector for extended delivery of rabeprazole and amoxicillin for treatment of peptic ulcer
In conclusion, greater compatibility, higher gastro-retention and higher anti-ulcer activity of the presently fabricated formulations to improve potential of formulation for redefining ulcer treatment are presented here. These learning exposed a targeted and sustained drug delivery potential of prepared microballoons in gastric region for ulcer therapeutic intervention as corroborated by in vitro and in vivo findings and, thus, deserves further attention for improved ulcer treatment.

Development and validation of HPLC-DAD method for the simultaneous determination of amoxicillin, metronidazole and rabeprazole sodium. Application to spiked simulated intestinal fluid samples.
Abstract This work deals with the development, validation and application of an HPLC-DAD method for the determination of a ternary mixture containing amoxicillin (AX), metronidazole (MZ) and the proton pump inhibitor rabeprazole sodium (RB). This triple therapy is used for treatment of Helicobacter pylori infection. Effective chromatographic separation between the three drugs was achieved using Thermo Hypersil BDS-C8 (4.6×250mm, 5μm particle size) column and a mobile phase composed of phosphate buffer pH 7 and acetonitrile (70: 30, by volume). The mobile phase was pumped isocratically at a flow rate of 1...

The chiral bioconversion and preclinical pharmacokinetic analysis of (R)-(+)-rabeprazole in beagle dogs by HPLC and HPLC-MS/MS.
Abstract In order to accurately investigate the preclinical pharmacokinetics of (R)-(+)-rabeprazole sodium injection, a reliable high-performance liquid chromatography (HPLC) method was developed using a Chiral-AGP column to prove that there is no chiral bioconversion of (R)-(+)-rabeprazole to (S)-(-)-rabeprazole in beagle dogs after single intravenous administration of (R)-(+)-rabeprazole sodium injection. An HPLC-tandem mass spectrometry (HPLC-MS/MS) method for analysis of (R)-(+)-rabeprazole was developed and validated, and used to acquire the pharmacokinetic parameters in beagle dogs. (R)-(+)-Rabeprazo...
