Lopinavir/ritonavir plus saquinavir in salvage therapy; pharmacokinetics, tolerability and efficacy.

ABSTRACT

Patients receiving a lopinavir/ritonavir and saquinavir dual protease inhibitor-based antiretroviral salvage regimen were studied to evaluate the pharmacokinetics, tolerability and efficacy of the regimen. Pharmacokinetic curves were obtained for lopinavir and saquinavir. Patient records were studied for adverse events and efficacy data. The pharmacokinetics of lopinavir and saquinavir were comparable with literature data, except for the saquinavir 0-12 h area under the curve and maximum concentration. The tolerability of the regimen was good and efficacy was encouraging.
