Dexlansoprazole MR is the R-enantiomer of lansoprazole that is delivered by a dual delayed release formulation. It is effective for symptom control of patients with gastroesophageal reflux disease. However, its efficacy in the treatment of Helicobacter pylori infection remains unclear. This pilot, randomized, controlled, head-to-head study was conducted to investigate whether the efficacy of si...

The present study was designed to compare the curative role of proton pump inhibitors, omeprazole, rabeprazole and lansoprazole against dexamethasone-induced ulcer model. Dexamethasone (5 mg/kg/day) was used as an ulcerogen. Dexamethasone suspended in 1% CMC in water was given orally to all rats. Omeprazole (20 mg/kg), rabeprazole (20 mg/kg), and lansoprazole (20 mg/kg) were administered by ora...

Objectives: To evaluate the influence of meals on the pharmacokinetics of omeprazole and rabeprazole and to investigate these PPIs with reference to CYP2C19 genotypes in healthy Japanese men. Methods: This was a randomized, open label, four-way crossover study. Twelve healthy Japanese male volunteers received a single oral dose of either 20 mg omeprazole or 10 mg rabeprazole, in the fasted stat...

BACKGROUND Gastric ulcers are a frequent problem in the United States. Proton pump inhibitors have been shown to increase healing rates and improve clinical symptoms. The objective of this study is to compare gastric ulcer healing rates for patients treated with a proton pump inhibitor (PPI) (omeprazole, rabeprazole, pantoprazole, or lansoprazole), an histamine 2- receptor antagonist (ranitidin...

A simple, precise, accurate and rapid high performance thin layer chromatographic method has been developed for the simultaneous estimation of ondansetron combinations in solid dosage form with omeprazole and rabeprazole, respectively. The method involved separation of components by TLC on a precoated silica gel 60 F(254) using a mixture of dichloromethane:methanol (9:1) as a mobile phase. Dete...

This study aimed to determine the influence of proton pump inhibitors (PPIs) on the pharmacokinetics of voriconazole and to characterise potential drug-drug interactions (DDIs) between voriconazole and various PPIs (omeprazole, esomeprazole, lansoprazole and rabeprazole). Using adjusted physicochemical data and the pharmacokinetic (PK) parameters of voriconazole and PPIs, physiologically based ...

To develop and validate simple, reproducible, stability indicating reverse phase high performance liquid chromatography for the simultaneous determination of Rebeprazole and Diclofenac in pharmaceutical solid dosage form. The method was based on HPLC separation of both drugs in reverse phase mode using Phenomenox C18 column with Waters HPLC system by using mobile phase composition of acetonitri...

OBJECTIVES Controversy has been prompted based on drug interaction between proton pump inhibitors (PPIs) and aspirin/clopidogrel leading to weakened effects. However, whether such interaction was drug-specific or class effect remains controversial. This study predicted the impact of esomeprazole and rabeprazole on efficacy of dual antiplatelet therapy (DAPT). METHODS This study, involving 150...
