Hyponatremia is the most common electrolyte balance disorder, especially in the elderly and polymedicated population. The authors report the case of an 83-year-old man with symptomatic severe hyponatremia due to Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH) related to pantoprazole. Pantoprazole was discontinued and serum sodium levels reached normal values in two months. To t...

Stress-related mucosal damage (SRMD) is a significant cause of morbidity and mortality in critically ill patients due to the gastrointestinal blood loss. Prophylaxis of SRMD with proton pump inhibitors or histamine-2 blockers has gained widespread use in intensive care units. Both demonstrated to be effective in reducing clinically significant bleedings, while PPIs has shown to exert some anti ...

The impact of the CYP2C19*17 allele on the pharmacokinetics of pantoprazole and omeprazole in previously studied children (n 40) was explored. When pantoprazole area under the plasma concentration versus time curve (AUC) was examined as a function of CYP2C19 genotype, a significantly lower AUC was observed for subjects identified as CYP2C19*1/*1 and *1/*17. For pantoprazole, a statistically sig...

BACKGROUND This study aimed to compare pantoprazole, a proton-pomp inhibitors (PPIs), and ranitidine, a H2 receptor antagonists (H2RA), in ceasing dyspeptic symptoms in the emergency department (ED). METHODS This randomized, double-blinded study compared the effectiveness of 50 mg ranitidine (Ulcuran(®)) and 40 mg pantoprazole (Pantpas(®)), given in a 100 mL saline solution by an intravenous ...

Imatinib mesylate (signal transduction inhibitor 571, Gleevec) is a potent and selective tyrosine kinase inhibitor, which was shown to effectively inhibit platelet-derived growth factor-induced glioblastoma cell growth preclinically. However, in patients, a limited penetration of imatinib into the brain has been reported. Imatinib is transported in vitro and in vivo by P-glycoprotein (P-gp; ABC...

AIM The optimal dosage of proton pump inhibitor in bleeding peptic ulcers remains controversial. The aim was to compare the clinical effectiveness of two doses of infusional pantoprazole in peptic ulcer bleeding. METHODS Peptic ulcer patients (n= 120) with bleeding stigmata were enrolled after successful endoscopic therapy. After an initial bolus injection of 80 mg pantoprazole, patients were...

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...

OBJECTIVES To investigate whether pantoprazole (20 mg/d) produces significantly greater symptom control than ranitidine (300 mg/d) in patients with gastro-oesophageal reflux disease (GORD). DESIGN Multicentre, randomised, double-blind, parallel-group comparison. SETTING 76 general practices in north-west Sydney and Newcastle, New South Wales (Australia), from 19 January 1999 to 22 September...
