Objective: To assess pharmacokinetics, safety and efficacy of darunavir/ritonavir (DRV/r) and optimized background regimen in treatment-experienced patients (6-17 years)
The influence of RTV on DRV pharmacokinetics was best characterized by ritonavir area under the curve on DRV clearance using a power function
When comparing Cobi and Rtv, multiple interactions must be taken into account: in comparison to Rtv, Cobi is a more selective CYP3A4 inhibitor and has no clinical effect on other isoenzymes inhibited by Rtv (eg Background: This study examined drug interactions between buprenorphine, a partial opioid agonist used for opioid dependence treatment and pain management, and the protease inhibitors (PIs) darunavir-ritonavir and fosamprenavir-ritonavir
The TMC114-C134 study assessed the pharmacokinetics and safety of darunavir/ritonavir 600 mg/100 mg twice daily in HIV-negative subjects with hepatic impairment (defined according to Child-Pugh classification A [mild] or B [moderate]) compared with matched, HIV GSK3640254 steady-state exposure was 40-47% lower when coadministered with etravirine but not meaningfully different with darunavir/ritonavir or both darunavir/ritonavir and etravirine

Week 4 paired blood plasma and cervicovaginal fluid samples were collected over 12 h
Intensive blood sampling for pharmacokinetics and fasting lipids was performed on days 7, 21, and 35
We simulated the concentration-time curve of a single oral 600 mg dose of darunavir in plasma with a well-stirred liver model, hence assuming passive partitioning of the drug from the plasma into the liver tissue, instantaneous homogeneous distribution across the liver mass and Design: Comparative pharmacokinetics study in patients

Here, we used mechanistic modelling to delineate the potential impact of drug transporters on darunavir pharmacokinetics and to identify current knowledge gaps We report darunavir, ritonavir, and etravirine pharmacokinetics in cervicovaginal fluid and blood plasma for women from the Gender, Race and Clinical Experience (GRACE) study
