report of maraviroc plasma concentrations when the drug is given as 150 mg once daily with lopinavir/ ritonavir. It is noteworthy that the current recommended minimum effective values of the trough concentration (50 ng/mL) and average concentration (100 ng/mL) were derived from a sub-study of the MOTIVATE trial, 3 where patients were administered 150 mg of maraviroc once daily or twice daily: t...
The three-direct-acting antiviral (3D) regimen containing ombitasvir, paritaprevir, ritonavir, and dasabuvir with or without ribavirin (RBV) is approved for treatment of hepatitis C virus (HCV) genotype 1 (GT1)/human immunodeficiency virus type 1 (HIV-1) coinfection. Results of a pharmacokinetic substudy of 3D and darunavir are presented. HCV/HIV-1-coinfected subjects were randomized to maintai...
The pharmacokinetics of a 2-g bolus of cefepime were measured in critically ill patients with normal renal function. Variable and low trough plasma drug concentrations were found, and 8 of 10 patients had levels below the MIC at which 50% of the isolates are inhibited for Pseudomonas aeruginosa. Computer simulations predicted that continuous infusion and shorter dosing intervals would increase ...
PURPOSE This prospective study was conducted to determine the incidence of lacrimal drainage obstruction (LDO) during S-1 chemotherapy and evaluate the association between the development of LDO and the concentrations of ingredients/metabolites of S-1 in tears and plasma. MATERIALS AND METHODS A total of 145 patients with gastric cancer who received adjuvant S-1 therapy were enrolled. Ophthal...
HIV-1 protease inhibitors (PIs) exhibit different protein binding affinities and achieve variable plasma and tissue concentrations. Degree of plasma protein binding may impact central nervous system penetration. This cross-sectional study assessed cerebrospinal fluid (CSF) unbound PI concentrations, HIV-1 RNA, and neopterin levels in subjects receiving either ritonavir-boosted darunavir (DRV), ...
BACKGROUND Whether the non-inferior efficacy and safety results of switching virologically suppressed HIV-1-infected patients from nevirapine immediate-release (NVP-IR) to NVP extended-release (NVP-XR) demonstrated in the TRANxITION study conducted in Europe and North America are also applicable to virologically suppressed HIV-infected Taiwanese patients remains unknown. We evaluated the compar...
Serum penicillin G falls to low levels 2 weeks after injection as benzathine penicillin G (BPG) in young adults. Using Pmetrics and previously reported penicillin G pharmacokinetic data after 1.2 million units were given as BPG to 329 male military recruits, here we develop the first reported population pharmacokinetic model of penicillin G after BPG injection. We simulated time-concentration p...
It is important to use vancomycin in a proper manner to ensure optimal drug exposure. Despite extensive use of vancomycin in children, studies on its optimal trough concentration (Ctrough) in the pediatric population remained rare. This retrospective study included children < 18 years old with culture-confirmed methicillin-resistant Staphylococcus aureus (MRSA) bacteremia who were hospitalized ...
BACKGROUND Ganciclovir, a drug against cytomegalovirus (CMV) infection, is generally well tolerated, but can cause neurotoxicity such as encephalopathy. Although ganciclovir-induced encephalopathy has been described in several reports, a literature search revealed that ganciclovir concentrations in the blood or cerebrospinal fluid were previously measured in only 3 patients with encephalopathy....
OBJECTIVES The primary objectives were to compare the incidences of severe thrombocytopenia, critical thrombocytopenia and a relative decline in platelets from baseline (≥50% decline) between patients receiving linezolid and those receiving vancomycin. The secondary objective was to assess the relationship between vancomycin trough concentration and adverse platelet outcomes. METHODS A matche...
