Recently, the mammalian target of rapamycin inhibitor everolimus (EVL) has been introduced as a novel immunosuppressant for heart transplant (HTx) recipients, and is expected to preserve renal function compared to conventional calcineurin inhibitors (CNIs). However, a considerable number of recipients treated with EVL were not free from worsening renal function regardless of CNI reduction. Data...

AIMS/INTRODUCTION The efficacy and safety of drugs can vary between different races or ethnic populations because of differences in the relationship of dose to exposure, pharmacodynamic response or clinical efficacy and safety. In the present post-hoc analysis, we assessed the influence of race on the pharmacokinetics, pharmacodynamics, efficacy and safety of monotherapy with the dipeptidyl pep...

OBJECTIVES Oral tacrolimus administration is the common route of drug delivery. Recent studies suggest sublingual administration of tacrolimus as an alternative route may produce comparable drug trough levels with similar or even lower doses than the oral route, especially in lung transplant recipients; however, most of this research does not encompass intraindividual variations compared betwee...

Isavuconazole, administered as the prodrug isavuconazonium sulfate, was recently approved by the U.S. Food and Drug Administration and the European Medicines Agency for the treatment of adults with invasive aspergillosis and mucormycosis. The objective of this analysis was to develop a population pharmacokinetic model using NONMEM (version 7.2) for subjects with hepatic impairment, using intrav...

Limited pharmacokinetic data for cefoperazone are available from the parturient. Because cefoperazone has a dual excretory pattern, primarily via the biliary system and secondarily via the kidney, pregnancy-induced physiologic alterations can influence its deposition and clearance. Twelve term parturients receiving cefoperazone prophylaxis after cesarean section were selected for study. After 2...

background: mostly seen toxicities following vancomycin are ototoxicity and nephrotoxicity. we here report a very low birth weight preterm neonate who developed severe episodes of apnea after accidental iatrogenic vancomycin overdose, responsive to treatment with double volume exchange transfusion. case report: a preterm neonate weighing 1380 grams received two doses of 10-fold of the normal do...

OBJECTIVE To determine the evolution of renal function in highly treatment-experienced patients with normal renal function at baseline receiving tenofovir disoproxil fumarate (TDF) as part of a fixed combined antiretroviral regimen and to identify prognostic factors of change in renal function, including tenofovir concentrations. METHODS A prospective 48-week open-label trial was carried out,...

Voriconazole is approved for treating invasive fungal infections. We examined voriconazole exposure-response relationships for patients from nine published clinical trials. The relationship between the mean voriconazole plasma concentration (C(avg)) and clinical response and between the free C(avg)/MIC ratio versus the clinical response were explored using logistic regression. The impact of cov...

BACKGROUND & AIMS Adalimumab is an efficacious therapy for active Crohn's disease, but long-term data are scarce. We conducted an observational study to assess the long-term clinical benefit of adalimumab in patients who failed to respond to infliximab, specifically focusing on the influence of trough serum concentration and antibodies against adalimumab on clinical outcome. METHODS A total o...

Methods A total of 1368 patients (24% female) were randomised (1:1) to either TMC278 25 mg q.d. or EFV 600 mg q.d., in combination with TDF/FTC (ECHO) or a choice of either TDF/FTC or AZT/3TC or ABC/3TC (THRIVE). The pharmacokinetics of TMC278 were best described by a two-compartment disposition model in which absorption was characterised by a lag time followed by a sequential zeroand first-ord...
