The present study was designed to compare ulcer protective effect of proton pump inhibitors viz. omeprazole, rabeprazole and lansoprazole against dexamethasone plus pylorus ligation induced ulcer model. Dexamethasone (5 mg/kg) was used as an ulcerogen. Dexamethasone suspended in 1% CMC in water was given orally to all the rats 15 min after the pylorus ligation. Omeprazole (20 mg/kg), rabeprazol...

Background. Randomized controlled trials (RCTs) have been conducted comparing the efficacy of rabeprazole 20 mg or omeprazole 20 mg once daily for patients with erosive gastroesophageal reflux disease (GERD). Until now, no study has synthesized all available data examining this issue. Method. Medline, Embase, and the Cochrane central register of controlled trials were searched (through December...

A simple, sensitive and precise stability indicating HPLC method has been developed for the estimation of rabeprazole and itopride in combined dosage form. A Phenomenex Gemini C-18, 5 μm column with a mobile phase containing 0.02 M ammonium acetate (pH 6): acetonitrile: methanol (45: 20: 35, v/v/v) was used. The flow rate was 1.0 mL min and effluents were monitored at 284 nm. Rabeprazole and it...

BACKGROUND Rabeprazole produces a profound and long-lasting inhibition of gastric acid secretion. The aim of the study was to monitor the safety and efficacy of rabeprazole administered to patients with erosive or symptomatic non-erosive reflux disease, in real-life healthcare settings. METHODS Male and female patients, aged ≥18 years, with endoscopy diagnosed GERD were included; patients rec...

BACKGROUND/AIMS It has been reported that proton pump inhibitors induce relaxation in different types of smooth muscles. The aim of this study is to investigate in vitro effects of proton pump inhibitors on human pylorus muscle. METHODS Pyloric sphincters were studied in 10 patients who were operated for stomach cancer. In isolated organ bath, control and re-sponse to rabeprazole were recorde...

The aim of this study was to determine the transport and distribution characteristics of levofloxacin in the rat stomach and investigate the effects of combination treatment with rabeprazole. A total of 160 Wistar rats were randomly divided into four treatment groups: 50 mg/kg levofloxacin, 100 mg/kg levofloxacin, 50 mg/kg levofloxacin + rabeprazole and 100 mg/kg levofloxacin + rabeprazole. For...

AIMS The aim was to explore the role of CYP2C19 polymorphism in short-term rabeprazole-based triple therapy against Helicobacter pylori infection. METHODS Patients with H. pylori infection were tested for CYP2C19 genotype as poor metabolizers (PMs) or extensive metabolizers (EMs, homozygous EM or heterozygous EM) and given rabeprazole for 7 days. Antibiotics (clarithromycin and amoxicillin) w...

Article history: Received on: 07/09/2013 Revised on: 19/09/2013 Accepted on: 23/11/2013 Available online: 29/11/2013 This work presents two simple and direct spectrophotometric methods for determination of rabeprazole sodium (RB) through charge transfer complexation reactions. The first method is based on the reaction of the drug with p-chloranilic acid (p-CA) in acetonitrile to give a red colo...

AIM The efficacy of pre-procedure oral proton pump inhibitor (PPI) administration for gastric endoscopic submucosal dissection (ESD) is unclear. This study evaluated oral PPI administration effectiveness on the day of ESD to prevent post-ESD bleeding. METHODS This study examined 55 patients who underwent ESD for gastric neoplasm. Group A comprised 31 patients who took rabeprazole sodium (RPZ)...
