Información del artículo

Darunavir es un nuevo inhibidor de la proteasa del virus de la inmunodeficiencia humana (VIH) que ha demostrado tener una gran utilidad en el tratamiento de los pacientes infectados por el VIH. Darunavir se metaboliza por el citocromo P450 hepático, por lo que su administración con dosis bajas de ritonavir resulta en un marcado incremento en la exposición a éste y permite reducir el número de comprimidos y de dosis diarias. Tanto darunavir como ritonavir actúan como inhibidores a la vez que sustratos del citocromo CYP3A4, por lo que son susceptibles de presentar interacciones medicamentosas con un amplio número de fármacos comúnmente usados en los pacientes infectados por el VIH. El objetivo de esta revisión es el de resumir los principales estudios llevados a cabo para evaluar dichas interacciones y servir de guía para el manejo del tratamiento con darunavir/ritonavir en la práctica clínica.

Interacciones medicamentosas

Darunavir is a new HIV protease inhibitor that has been shown to be highly useful in HIV-infected patients. This drug is primarily metabolized by the liver through the cytochrome P450 3A4 (CYP3A4) isozyme and consequently coadministration with low doses of ritonavir markedly increases exposure and allows both daily doses and pill burden to be reduced. Both darunavir and ritonavir act as inhibitors and substrates of CYP3A4 and may therefore present pharmacological interactions with a large number of drugs commonly used in HIV-infected patients. The present review aims to summarize the main studies that have evaluated drug interactions and to provide recommendations on treatment with darunavir/ritonavir in clinical practice.
