Pharmacokinetics of etravirine, raltegravir and darunavir/ritonavir in treatment experienced patients

AIDS. 2010 Oct 23;24(16):2581-3. doi: 10.1097/qad.0b013e32833d89fa.

Abstract

Etravirine is an enzyme inducer and could lower the concentration of combined drugs. Ten HIV-1-infected patients with multiple treatment failure received raltegravir (400 mg, twice daily) and darunavir/ritonavir (600/100 mg, twice daily). Addition of etravirine (200 mg, twice daily) leads to a significant increase in raltegravir and darunavir trough concentrations (405 vs. 118 and 3837 vs. 2241 ng/ml) and darunavir area under the curve (AUC(12h)) (50 083 vs. 36 277 ng h/ml). All pharmacokinetic parameters appeared to be highly variable regardless to the addition of etravirine.
