BACKGROUND: The rate of rebleeding from peptic ulcers could differ between Asian and Western populations. AIM: To determine whether the observed twofold difference in rebleeding rates in two similarly designed clinical trials (one in Hong Kong [n=240], the other in a multinational Western population [n=764, http://ClinicalTrials.gov Identifier: NCT00251979]) can be explained by differences in baseline patient characteristics. METHODS: Two-factor and multifactor analyses (adjusted by demographics, established risk factors for peptic ulcer and peptic ulcer bleeding, and disease severity variables) were performed using pooled data from the two studies...

The functionalized cellulose ester MCN was firstly synthesized and used to cross-link gelatin by amidation between -NH2 in gelatin and active ester groups in MCN to form a composite polymer network Gel-MCN, which was confirmed by Van Slyke method, FTIR, XRD and TGA-DTG spectra. The model drug omeprazole was loaded in Gel-MCN composites mainly by electrostatic interaction and hydrogen bonds, which were certified by FTIR, XRD and TGA-DSC. Thermal stability, anti-biodegradability, mechanical property and surface hydrophobicity of the composites with different cross-linking extents and drug loading were systematically investigated...

Drug-drug interactions (DDIs) occur when the action of one drug interferes with or alters the activity of another drug taken concomitantly. This can lead to decreased drug efficacy or increased toxicity. Because of DDIs, physicians in the clinical practice attempt to avoid potential interactions when multiple drugs are co-administrated, however there is still a large knowledge gap in understanding how drugs taken in the past can contribute to DDIs in the future. The goal of this study is to investigate the consequence of neonatal drug exposure on efficacy of other drugs administered to adult life...

Zollinger-Ellison syndrome (ZES) is caused by hypersecretion of gastrin from duodenal or pancreatic gastrinomas. We report a case of a 57-year-old female who presented with chronic diarrhea. CT abdomen showed multiple liver masses. Liver biopsy suggested metastatic well-differentiated neuroendocrine tumor. Serum gastrin level was markedly elevated. MRI abdomen, somatostatin receptor scintigraphy and endoscopic ultrasound failed to reveal primary site of the tumor. Upper gastrointestinal endoscopy showed hyperplastic gastric folds and multiple duodenal ulcers consistent with ZES...

Purpose - The CEIBA cocktail consisting of caffeine (CAF), omeprazole (OZ), dextromethorphan (DM) and losartan (LOS) was previously proposed for the clinical phenotyping of five major human cytochrome P450 (CYP) isoenzymes. This work aimed to assess the usefulness of CEIBA cocktail to study non-clinical drug interactions in the rat. Methods - Wistar rats were divided into five groups to receive a single-oral dose of each probe drug (CAF, OZ, LOS, DM), individually or in combination as a cocktail. Plasma concentrations of the probe drugs and their metabolites [paraxanthine (1,7-X), 5-hydroxyomeprazole (5-OZ), losartan carboxylic acid (E-3174), dextrorphan (DX) and 3-methoxymorphinan (3-MM)] were determined by LC-MS/MS, and the corresponding pharmacokinetic parameters were estimated by non-compartmental analysis...

BACKGROUND: Controversies were previously observed with the concomitant use of clopidogrel and Proton Pump Inhibitors (PPIs), especially omeprazole, following coronary angioplasty. Even though several studies showed no interaction between clopidogrel and PPIs, questions have been raised about the decrease in antiplatelet effects of clopidogrel with PPIs. A previously published meta-analysis showed concomitant use of clopidogrel and PPIs to be associated with higher adverse cardiovascular outcomes...

Heartburn and acid regurgitation are the cardinal symptoms of gastroesophageal reflux and occur commonly in the Canadian population. Multiple non-prescription treatment options are available for managing these symptoms, including antacids, alginates, histamine-H2 receptor antagonists (H2RAs), and proton-pump inhibitors (PPIs). As a result, pharmacists are ideally positioned to recommend appropriate treatment options based upon an individual's needs and presenting symptoms, prior treatment response, comorbid medical conditions, and other relevant factors...

Recent evidence suggests that high dose and/or long term use of proton pump inhibitors (PPIs) may increase the risk of adverse cardiovascular events in older patients, but mechanisms underlying these detrimental effects are not known. Taking into account that the senescent endothelial cells have been implicated in the genesis or promotion of age-related cardiovascular disease, we hypothesized an active role of PPIs in senescent cells. The aim of this study is to investigate the changes in gene expression occurring in senescent and non-senescent human coronary artery endothelial cells (HCAECs) following Omeprazole (OPZ) or Lansoprazole (LPZ) treatment...

We report the case of a 4-month-old girl who developed encephalopathy, seizures, and respiratory compromise as a result of baclofen toxicity. After some investigation, the accidental ingestion of baclofen was caused by an error in compounding the patient's prescribed omeprazole with baclofen rather than sodium bicarbonate at a retail pharmacy. This error occurred because these two drugs, which were available as powders, were located side by side on the pharmacy shelf. The pharmacist further reported that their normal practice was to use injectable sodium bicarbonate rather than powder to compound an omeprazole suspension; however, the injectable form was not available due to a national shortage...

Crospovidone and microcrystalline cellulose (MCC) are pharmaceutical fillers well known in the pulmonary pathology literature. Fillers are inactive substances incorporated into medications to facilitate drug delivery. By examining 545 consecutive gastrointestinal surgical specimens from 302 patients between September 11, 2015 and October 23, 2015, we identified the fillers in 29 specimens from 26 patients. The control group consisted of an equal number of consecutive site-matched specimens collected during this same time...

The intestinal microbiota might contribute to enteropathy associated with use of non-steroidal anti-inflammatory drugs (NSAIDs), but there have been few human studies of this association. We performed a placebo-controlled study to determine whether a delayed release antibiotic formulation (rifaximin-EIR) prevented development of intestinal lesions in persons taking daily NSAIDs. Sixty healthy volunteers (median age 26 years, 42% female) were given the NSAID diclofenac (75 mg twice daily) plus omeprazole (20 mg once daily), and either rifaximin-EIR (400 mg) or placebo, twice daily for 14 days...

OBJECTIVE: Proton pump inhibitors are frequently administered on clinical symptoms in neonates but benefit remains controversial. Clinical trials validating omeprazole dosage in neonates are limited. The objective of this trial was to determine the minimum effective dose (MED) of omeprazole to treat pathological acid reflux in neonates using reflux index as surrogate marker. DESIGN: Double blind dose-finding trial with continual reassessment method of individual dose administration using a Bayesian approach, aiming to select drug dose as close as possible to the predefined target level of efficacy (with a credibility interval of 95%)...

OBJECTIVES: Gastroesophageal reflux disease (GERD) is a prevalent gastrointestinal disease that causes troublesome symptoms and/or complications. The major therapeutic strategy for GERD focuses mainly on symptom alleviation using proton pump inhibitors (PPIs), which does not produce a perfect response in all patients. An approach with new therapeutic agents for GERD seems to be essential. The aim of this study was to review animal and human studies investigating the effect of medicinal plants in GERD as well as mechanisms underlying their therapeutic effects...

Acid-related gastric diseases are associated with disorder of digestive tract acidification due to the acid secretion by gastric proton pump, H(+),K(+)-ATPase. Omeprazole is one of the persuasive irreversible inhibitor of the proton pump H(+),K(+)-ATPase. However, the reports on the mechanistic pathway of irreversible proton pump inhibitors (PPIs) on the acid activation and formation of disulfide complex are scarce in the literature. We have examined the acid activation PPIs, i.e., timoprazole, S-omeprazole and R-omeprazole using M062X/6-31++G(d,p) in aqueous phase with SMD solvation model...
