Flurbiprofen is a non-steroidal anti-inflammatory drug. We evaluated the bioequivalence of a new formulation of flurbiprofen axetil for injection and the reference drug ROPION (another kind of flurbiprofen axetil injection marketed for use) in healthy Chinese subjects. This is a single-centre, randomized, open-label, single-dose, two period crossover bioequivalence study. Each subject received a single intravenous injection at the dose of 50 mg under fasting. The drug was dissolved in 100 mL normal saline, and the injection was completed in 15 minutes. There was a 7-day washout period between the two administrations. The plasma concentrations of flurbiprofen were measured by LC-MS/MS, and descriptive statistics were used to describe the safety outcomes including adverse events (AEs) and adverse drug reactions (ADRs). Twenty-four subjects were enrolled in this study. Mean values of primary PK parameters (Tmax , Cmax , AUC0-t , AUC0-∞ , λz , T1/2 ) were similar (P > 0.05). Tmax for both products is 0.3 hours. The 90% confidence intervals (CIs) for peak concentration Cmax ranged between 96.87% and 100.42%, and the area under curve AUC0-t and AUC0-∞ ranged between 99.09% and 104.29% and 98.97% and 104.29%, respectively. The 90% CIs for the geometric means and ratios of primary PK endpoints of flurbiprofen axetil injection to reference drug ranged between 98.97% and 104.29%. The adverse event rate of the test product was 8.3% and no serious adverse events (SAE) occurred in this clinical study. We concluded that the test product and the reference drug were bioequivalent and the safety was high in healthy Chinese subjects.Hypaconitine, a neuromuscular blocker, is a diterpene alkaloid found in the root of Aconitum carmichaelii. Although hypaconitine was shown to affect various physiological responses in neurological models, the effect of hypaconitine on cell viability and the mechanism of its action of Ca2+ handling is elusive in cortical neurons. This study examined whether hypaconitine altered viability and Ca2+ signalling in HCN-2 neuronal cell lines. Cell viability was measured by the cell proliferation reagent (WST-1). Cytosolic Ca2+ concentrations [Ca2+ ]i was measured by the Ca2+ -sensitive fluorescent dye fura-2. In HCN-2 cells, hypaconitine (10-50 μmol/L) induced cytotoxicity and [Ca2+ ]i rises in a concentration-dependent manner. Removal of extracellular Ca2+ partially reduced the hypaconitine's effect on [Ca2+ ]i rises. Furthermore, chelation of cytosolic Ca2+ with BAPTA-AM reduced hypaconitine's cytotoxicity. In Ca2+ -containing medium, hypaconitine-induced Ca2+ entry was inhibited by modulators (2-APB and SKF96365) of store-operated Ca2+ channels and a protein kinase C (PKC) inhibitor (GF109203X). Hypaconitine induced Mn2+ influx indirectly suggesting that hypaconitine evoked Ca2+ entry. In Ca2+ -free medium, treatment with the endoplasmic reticulum Ca2+ pump inhibitor thapsigargin abolished hypaconitine-induced [Ca2+ ]i rises. Conversely, treatment with hypaconitine inhibited thapsigargin-induced [Ca2+ ]i rises. However, inhibition of phospholipase C (PLC) with U73122 did not inhibit hypaconitine-induced [Ca2+ ]i rises. Together, hypaconitine caused cytotoxicity that was linked to preceding [Ca2+ ]i rises by Ca2+ influx via store-operated Ca2+ entry involved PKC regulation and evoking PLC-independent Ca2+ release from the endoplasmic reticulum. Because BAPTA-AM loading only partially reversed hypaconitine-induced cell death, it suggests that hypaconitine induced a second Ca2+ -independent cytotoxicity in HCN-2 cells.Obesity and type 2 diabetes mellitus are risk factors for hypertension, coronary heart disease, cardiac arrhythmias including atrial fibrillation, heart failure and sudden cardiac death. The effects of obesity and diabesity on heart rhythm were investigated in the Zucker diabetic fatty (ZDF) and Zucker fatty (ZF) compared to the Zucker lean (ZL) control rat. In vivo biotelemetry techniques were used to assess the electrocardiogram and other cardiac and metabolic parameters. ZDF rats were characterized by age-dependent elevations in fasting and non-fasting blood glucose, glucose intolerance and weight gain and ZF rats were characterized by smaller elevations in fasting and non-fasting blood glucose and greater weight gain compared to ZL rats. Heart rate (HR) was progressively reduced in ZDF, ZF and ZL rats. SL-327 supplier At 195 days (6.5 months) of age there were significant differences in HR between ZDF (265 ± 8 bpm, n = 10), ZF (336 ± 9 bpm, n = 10) and ZL (336 ± 10 bpm, n = 10) rats and significant differences in HRV between ZDF (22 ± 1 bpm, n = 10), ZF (27 ± 1 bpm, n = 10) and ZL (31 ± 1 bpm, n = 10) rats. Power spectral analysis revealed no significant (P > 0.05) differences in HRV at low frequencies, reduced HRV at high frequencies and increased sympathovagal balance in ZDF compared to ZF and ZL rats. HR was reduced by ageing and additionally reduced by diabesity in the absence of changes in physical activity and body temperature. Reductions in HRV associated with altered sympathovagal drive might partly underlie disturbed HR in the ZDF rat. Possible explanations for reduced HR and future mechanistic studies are discussed.
Renal impairment (RI) and renal drug-related problems (rDRP) often remain unrecognized in the community setting. A "renal pharmacist consultant service" (RPCS) at hospital admission can support patient safety by detecting rDRP. However, the efficient information sharing from pharmacists to physicians is still discussed. The aim of the study was to test the implementation of a RPCS and its effectiveness on prescription changes and to evaluate two ways of written information sharing with physicians.

Urological patients with eGFR
of 15-59ml/min and ≥1 drug were reviewed for manifest and potential rDRP at admission by a pharmacist. Written recommendations for dose or drug adaptation were forwarded to physicians comparing two routes July-September 2017 paper form in handwritten chart; November 2017-January 2018 digital PDF document in the electronic patient information system and e-mail alert. Prescription changes regarding manifest rDRP were evaluated and compared with a previous retrospective study without RPCS.
