Subjects were randomized to receive three single doses of the following treatments: dolutegravir 250-mg suspension, moxifloxacin 400-mg tablet, and placebo suspension; each treatment was separated by a 14-day washout period. Treatment [http://www.selleckchem.com/Proteasome.html Proteasome inhibitor] with the dolutegravir and placebo suspension was blinded, whereas treatment with moxifloxacin was open label. The pharmacokinetic exposure at a supratherapeutic dose of dolutegravir 250?mg was 2�C4 times higher than the pharmacokinetic exposure at clinically relevant dosages (50?mg once or twice/day). The upper limit of the 90% confidence interval (CI) for the placebo-adjusted mean change from baseline of the QTc interval (����QTcF) using Fridericia's formula was less than 10?msec at all time points. The sensitivity of the study to detect modest increases in QT interval was established with moxifloxacin, a positive control for QT-interval prolongation. The maximum ����QTcF values for dolutegravir and moxifloxacin were observed at 4?hours: 1.99?msec (90% CI ?0.55�C4.53?msec) and 9.58?msec (90% CI 7.05�C12.11?msec), respectively. This pharmacokinetic-pharmacodynamic model demonstrates no relationship between dolutegravir plasma concentration and ����QTcF. Furthermore, a supratherapeutic dose of dolutegravir was generally well tolerated without any serious or severe adverse events. As such, dolutegravir does not affect cardiac repolarization.

Retrospective quasi-experimental study. Urban level I trauma center. A total of 200 patients treated with vancomycin for at least 72?hours for confirmed, complicated methicillin-resistant Staphylococcus aureus (MRSA) bacteremia during one of two study phases relative to the implementation of the vancomycin dosing guidelines targeting serum trough concentrations of 15�C20?mg/L: 2005�C2007 (preperiod phase) and 2008�C2010 (postperiod phase). One hundred patients in each phase were matched in a 1:1 ratio according to diagnosis, any concomitant nephrotoxic agents (e.g., aminoglycosides, colistin, acyclovir), and age?��?5?years. Patients in the preperiod had significantly lower success rates with vancomycin than those in the postperiod (45% vs 60%, p=0.034). Median length of stay (LOS) was not significantly higher in patients in the preperiod versus postperiod (15?days vs 13.5?days; p=0.28), and patients in the preperiod received a longer median duration of vancomycin versus those in the postperiod (13?days vs 8.5?days; p
