BACKGROUND Many of the currently used Helicobacter pylori eradication regimens fail to cure the infection due to either antimicrobial resistance or poor patient compliance. Those patients will remain at risk of developing potentially severe complications of peptic ulcer disease. AIM We studied the impact of the antimicrobial resistance on the efficacy of a short course pantoprazole based trip...

The aim of the present study was to determine the effects of the short-term application of pantoprazole on the co-treatment of acute ST-segment elevation myocardial infarction (STEMI) with aspirin and clopidogrel. A total of 207 acute patients showing primary symptoms of STEMI, who received successful emergent percutaneous coronary intervention treatment during hospitalization were randomly div...

As a direct-acting inhibitor of CYP2C19 in vitro, lansoprazole is more potent than omeprazole and other proton pump inhibitors (PPIs), but lansoprazole does not cause clinically significant inhibition of CYP2C19 whereas omeprazole does. To investigate this apparent paradox, we evaluated omeprazole, esomeprazole, R-omeprazole, lansoprazole, and pantoprazole for their ability to function as direc...

Active transport of drug into milk is a major concern in breastfeeding. Abcg2 plays a critical role in drug transfer into rat milk, which is consistent with evidence in humans. Although it is estimated that approximately half of all therapeutic agents are chiral, there have been few reports of stereoselective interactions with ABCG2. The purpose of this study was to investigate the interaction ...

BACKGROUND This study evaluated the effect of omeprazole or pantoprazole on platelet reactivity in non-ST-segment elevation acute coronary syndrome (NSTE-ACS) patients receiving clopidogrel. METHODS Consecutive patients with NSTE-ACS (n = 620) from general hospital of Shenyang Military Command were randomized to the omeprazole or pantoprazole (20 mg/d) group (1:1), and received routine dual a...

Introduction: Atrial arrhythmia is a common complication in patients with gastro esophageal reflux disease (GERD). The treatment of palpitation is relatively problematic in these patients, especially if there is not enough evidence of cardiovascular or systemic diseases. The esophagus is in close proximity to the left atrium posterior wall. Hypothetically, locally released cytokines from esopha...

Patients receiving dual antiplatelet treatment with aspirin and clopidogrel are commonly treated with proton pump inhibitors (PPIs). Attenuating effects on platelet response to clopidogrel have been reported solely for the PPI omeprazole. PPIs differ in their metabolisation properties as well as their potential for drug-drug interactions. The aim of this study was to investigate the impact of d...

The aim of this study was to elucidate the roles of P-glycoprotein (P-gp/ABCB1) and breast cancer resistance protein (BCRP/ABCG2) in the plasma concentration, biliary excretion, and distribution to the liver, kidney, and brain of sunitinib. The pharmacokinetics of sunitinib was examined in rats treated with PSC833 (valspodar) and pantoprazole, potent inhibitors of P-gp and BCRP, respectively. T...
