Proton pump inhibitors (PPIs) have been widely used in the treatment of gastroesophageal reflux disease and peptic ulcer disease. Although they have a potent acid suppressive effect and excellent efficacy in acid-related diseases, PPI-induced rhabdomyolysis has been reported. Here, we report the case of a patient with reflux esophagitis who developed rhabdomyolysis after esomeprazole treatment. A 67-year-old man with reflux esophagitis who had started esomeprazole treatment for the preceding 10 months complained of back and limb fatigue and myalgia...

BACKGROUND: Pazopanib is an oral tyrosine-kinase inhibitor that is approved by the U.S. Food and Drug Administration for treatment of metastatic renal cell carcinoma (mRCC). Pharmacokinetic data have shown that concomitant administration of pazopanib and esomeprazole, a proton pump inhibitor (PPI), leads to decreased area under the curve and thus decreased exposure of pazopanib by 40%. Despite the pharmacokinetic data published to date, the clinical significance and impact on patient outcomes resulting from decreased pazopanib exposure remains unknown...

INTRODUCTION: The discovery of new treatments that prevent or treat preeclampsia would be a major advance. Antiangiogenic factors soluble fms-like tyrosine kinase-1 (sFlt-1) and soluble endoglin (sENG) are secreted in excess from the placenta, causing hypertension, endothelial dysfunction, and multiorgan injury. We recently identified metformin and esomeprazole as potential treatments for preeclampsia. Both reduce placental and endothelial secretion of sFlt-1 and soluble endoglin, and reduce endothelial dysfunction...

INTRODUCTION: the majority of studies of acute gastrointestinal bleeding in children are retrospective, focusing on therapeutic endoscopy. Previous studies performed in adult patients have demonstrated that both scheduled second look endoscopy and high dose continuous omeprazole infusion are effective in the prevention of peptic ulcer rebleeding. The aim of this study was to compare the efficacy of these two strategies using esomeprazole for the prevention of rebleeding following primary endoscopic hemostasis in children with peptic ulcers...

BACKGROUND AND GOAL: Cytochrome P450 (CYP) enzymes are responsible for the conversion of clopidogrel into its active metabolite and the metabolism of proton pump inhibitors (PPIs), which may also inhibit CYP enzymes. A current Food and Drug Administration advisory suggests avoiding esomeprazole and omeprazole while taking clopidogrel because of concerns that PPIs may compromise clopidogrel's antiplatelet effects. The objective of the present study was to examine the robustness of this interaction using a well-controlled study design in a population of participants free of confounders...

A new validated bio-analytical LC-MS/MS method was developed for the simultaneous extraction and determination of four proton pump inhibitors: esomeprazole, lansoprazole, pantoprazole and rabeprazole in human plasma using escitalopram as an internal standard. The proteins in plasma samples were precipitated using acetonitrile for the extraction of analytes which is a simple economic method. The separation was accomplished using a mobile phase composed of 10 mM ammonium formate: acetonitrile: methanol (20:40:40% v/v) at a flow rate of 0...

Chirally pure molecules or enantiomers are non-superimposable mirror images of each other with a chiral center (such as carbon, sulphur, nitrogen or phosphorous atom). An equimolar mixture of enantiomers forms a racemate. Chirally pure molecules (single enantiomers) are important in the field of drug discovery as the drug targets such as enzymes and receptors are enantioselective in nature. Clinical studies have demonstrated that chirally pure drugs exhibit different pharmacokinetic and metabolic profiles, reduced adverse events, improved safety profiles and similar therapeutic activity at lowered drug dosage as compared with the racemate in many therapeutic areas...
