Highly active antiretroviral therapy can provide sustained viral suppression and a beneficial immunological response in both antiretroviral-naive and -experienced pediatric patients infected with HIV. While there have been many antiretroviral studies in adults infected with HIV, considerably less information is available in similar HIV-infected pediatric or adolescent patients. Tipranavir, a new-generation protease inhibitor approved for use in adults with resistant HIV strains, has recently been studied in HIV-infected children and adolescents. In this article, we summarize available pharmacokinetic, safety, tolerability and efficacy data obtained from children and adolescents treated with a pediatric tipranavir formulation.
