5. Study Description
Brief Summary
The purpose of this clinical trial is to characterize drug interactions between one medicinal herb widely used by HIV infected patients: Echinacea sp. and the protease inhibitor darunavir/ritonavir.
Detailed Description
15 patients on antiretroviral therapy with darunavir/ritonavir 600/100 mg twice a day during four weeks will be recruited. The patients will receive treatment with Echinacea purpurea for 14 days, 500 mg every 6 hours. A 12 hour pharmacokinetic curve will be obtained at baseline and on day 14.
