Pharmacokinetics, Short-term Safety and Efficacy of the Approved Once-daily Darunavir/Ritonavir Dosing Regimen in HIV-infected Children.

In this multicenter pharmacokinetic study in HIV-infected children (6-12 years of age), we validated the approved once-daily darunavir/ritonavir dosing recommendations. The geometric mean darunavir area under the plasma concentration-time curve was 63.1 h·mg/L, substantially lower than the mean value observed in adults. However, all trough levels were adequate, and short-term virologic outcome was good. These data support the use of the darunavir/ritonavir once-daily dosing recommendations.
