Darunavir/ritonavir and rosuvastatin
26 August 2010. Related: Conference reports, PK and drug interactions, World AIDS 18 Vienna 2010.
Coadministration of darunavir/ritonavir (600/100 mg twice daily) and rosuvastatin (10 mg once daily) was studied in 12 HIV- subjects. The geometric mean AUC for rosuvastatin increased by 48% in the presence of darunavir/ritonavir and Cmax increased by 2.44-fold. There were no significant changes in darunavir or ritonavir AUC or Cmax. Lipid lowering effects of rosuvastatin were not significantly altered, despite higher concentrations of rosuvastatin. There were no adverse events attributable to the interaction.
