Abstract

We report darunavir, ritonavir, and etravirine pharmacokinetics in cervicovaginal fluid and blood plasma for women from the Gender, Race and Clinical Experience (GRACE) study. Eight women received darunavir-ritonavir (600/100 mg) twice daily (b.i.d.); two also received etravirine (200 mg) b.i.d. Week 4 paired blood plasma and cervicovaginal fluid samples were collected over 12 h. Darunavir and etravirine cervicovaginal fluid exposures were higher than blood plasma exposures; ritonavir cervicovaginal fluid exposure was lower than blood plasma exposure. The high exposures of darunavir and etravirine in cervicovaginal fluid warrant further evaluation of these drugs for use in HIV-1 prevention.
