Trough (predose) voriconazole concentrations in plasma and pulmonary epithelial lining fluid (ELF) of lung transplant recipients receiving oral voriconazole preemptive treatment were determined. The mean (± standard deviation [SD]) ELF/plasma ratio was 12.5 ± 6.3. A strong positive linear relationship was noted between trough plasma and ELF voriconazole concentrations (r(2) = 0.87), suggesting ...

Differences in virologic response were compared in 32 HIV-infected children with a nelfinavir trough concentration either below (n=7) or above (n=25) 0.8 mg/L. Virologic response at week 48 was observed in 29% of children with subtherapeutic nelfinavir troughs versus 80% in children with therapeutic nelfinavir troughs (P=.02).

BACKGROUND Crizotinib, an ATP-competitive receptor tyrosine kinase inhibitor of both anaplastic lymphoma kinase (ALK) and the hepatocyte growth factor receptor, commonly causes several adverse events (AEs). The clinical utility of measuring the plasma concentration of crizotinib in patients with non-small-cell lung cancer (NSCLC) has not been fully elucidated. The aim of this study was to evalu...

AIMS The aim of the present study was to demonstrate evidence of reduced thrombin generation at the trough plasma rivaroxaban concentration. METHODS A single-centre, prospective, nonrandomized, drug-intervention, self-controlled study was conducted in 51 anticoagulation therapy-naïve patients with nonvalvular atrial fibrillation. Plasma rivaroxaban concentration was measured by liquid chromat...

Trough blood or plasma concentration measurements of CsA must be carefully interpreted in OLT patients in relation to hepatic function, sample timing, assay specificity, and concurrent drug therapy. The RIA:HPLC ratio of blood or plasma measurements will vary with the patient's liver function, the time of blood sampling in reference to the time of drug administration, the absolute CsA concentra...

OBJECTIVES The aim of this study was to develop and validate a population pharmacokinetic model for nevirapine in a population of HIV-infected adults and to evaluate the influence of nevirapine dosing regimen and patient characteristics on nevirapine trough concentration. METHODS HIV-infected adults receiving oral nevirapine for at least 4 weeks were included. A concentration-time profile was...

The relationship between nevirapine plasma concentrations and the durability of both viral suppression (VS) and selection of nevirapine primary resistance mutations (PRMs) was evaluated. A nevirapine trough concentration (Ctrough) of >4,300 ng/ml was found to predict longer VS. Patients with nevirapine Ctrough s ranging from 3,100 to 4,300 ng/ml had higher probabilities of developing PRMs than ...
