OBJECTIVE: Off-label prescribing of proton pump inhibitors (PPIs) to infants to treat symptoms attributed to gastroesophageal reflux disease (GERD) is widely reported, despite evidence that PPIs are no more effective than placebo in relieving those symptoms. To initiate discussion about appropriate prescribing of these drugs for infants, we describe the characteristics of PPI use among infants in New Zealand. METHODS: In this population-based study we used routinely collected dispensing data to identify all children born between 2005 and 2012 who were dispensed a government-subsidized PPI (omeprazole, lansoprazole, pantoprazole) before their first birthday...

Background/Aims: Concerns that proton pump inhibitors (PPIs) diminish the efficacy of clopidogrel could hamper the appropriate prescription of PPIs. We evaluated the influence of pantoprazole on the antiplatelet effect of clopidogrel compared with ranitidine, which is regarded as safe, after stratification of the population according to the presence of a cytochrome (CYP) 2C19 polymorphism in Korea. Methods: Forty patients who underwent dual antiplatelet therapy were randomized to receive pantoprazole (n=20) or ranitidine (n=20)...

BACKGROUND: Autophagy is a survival mechanism that allows recycling of cellular breakdown products, particularly in stressed cells. Here we evaluate the hypotheses that up-regulation of autophagy is a common mechanism of resistance to chemotherapy, and that drug resistance can be reversed by inhibiting autophagy with a proton pump inhibitor. METHODS: We exposed human PC3, LNCaP and MCF7 cells to seven clinically-used chemotherapy drugs ± pantoprazole, examined the up-regulation of autophagy and the effect on cellular proliferation by Western Blots, MTS assay and colony-forming assay...

The delivery of drugs to the brain is a constant challenge due to limitations imposed by the blood-brain barrier (BBB). Various methods of bypassing the BBB are under investigation. One approach is intranasal administration, where the olfactory region of the nasal cavity extends up to the cranial cavity and provides direct access to the brain. The pharmacokinetics of this transport and factors that determine transport rates and capacity is of vital importance for evaluating the clinical value of this route...

Mutual chiral recognition of four stereoisomers of tadalafil and three pairs of enantiomers of proton pump inhibitors (PPIs) including pantoprazole, lansoprazole, and omeprazole, as well as quantitative analysis of enantiomeric excess is achieved on the basis of the competitive fragmentation of doubly charged trimeric Ni(II) cluster ions. Compared with a singly charged trimeric cluster ion, a doubly charged trimeric cluster ion was proved efficient in the recognition of chiral drugs with one or multiple chiral centers, due to its rich fragmentation ions...

Background Geriatric falls are leading causes of hospital trauma admissions and injury-related deaths. Medication use is a crucial element among extrinsic risk factors for falls. To reduce fall risk and the prevalence of adverse drug reactions, potentially inappropriate medication (PIM) lists are widely used. Objective Our aim was to investigate the possible predictors of geriatric falls annualized over a 5-year-long period, as well as to evaluate the medication use of nursing home residents. Setting Nursing home residents were recruited from the same institution between 2010 and 2015 in Szeged, Hungary...

Recent studies report an increased risk of enteric infections in patients treated with proton pump inhibitors (PPIs). Polymorphonuclear neutrophils (PMNs) play a key role in host response to bacterial infection. We evaluated the effect of omeprazole and pantoprazole treatment on the PMN function. Fifteen patients were treated with omeprazole 20 mg daily and 15 patients with pantoprazole 40 mg daily for 7 days. Treatment with omeprazole or pantoprazole had no effect on spontaneous nitroblue tetrazolium (NBT) test results...

Both proton pump inhibitors (PPIs) and clopidogrel are widely prescribed in the Asia-Pacific population. PPIs are the mainstay therapeutic agents for prophylaxis against aspirin gastropathy and for ARDs (Acid Related Disorders) including gastroesophageal reflux disease (GERD). They are also co-prescribed with oral anticoagulant agents (OAAs)and with dual-antiplatelet therapy (DAPT) for the treatment and prevention of gastrointestinal (GI) bleeding. Clopidogrel belongs to the drug class of thienopyridines, and is currently the most widely prescribed OAA either alone or in combination with aspirin...

Patients with gastroesophageal reflux disease (GERD) are routinely prescribed one of the six FDA approved proton pump inhibitors (PPI). All of these PPI are inhibitors of CYP2C19 enzyme to varying degrees. The phenotype pantoprazole-(13)C breath test (Ptz-BT) was used to identify patients who are poor metabolizers (PM) and the extent of phenoconversion of CYP2C19 enzyme activity caused by four PPI (omeprazole, esomprazole pantoprazole and rabeprazole) in 54 newly diagnosed GERD patients prior to initiating randomly selected PPI therapy and 30 d after PPI therapy...
