Importance of protease inhibitor plasma levels in HIV-infected patients treated with genotypic-guided therapy: pharmacological data from the Viradapt Study

Abstract

Multiple parameters determine the response to antiretroviral therapy and causes other than the development of drug resistance should be considered in the setting of therapeutic failure. Suboptimal concentrations of PI limit the response to antiretroviral therapy. Therapeutic drug monitoring of the PI plasma concentration may therefore prove useful in optimizing antiretroviral therapy.
