Ritonavir + Etravirine Interaction

Description

dolutegravir/darunavir/ritonavir ↓ dolutegravir ↔ etravirine The effect of etravirine on dolutegravir plasma concentrations was mitigated by co- administration of darunavir/ritonavir or lopinavir/ritonavir, and is expected to be mitigated by atazanavir/ritonavir. dolutegravir/lopinavir/ritonavir ↔ dolutegravir ↔ etravirine Dolutegravir should only be used with etravirine tablets when co- administered with atazanavir/ritonavir, darunavir/ritonavir, or lopinavir/ritonavir. HIV-antiviral agents: protease inhibitors (PIs) atazanavir (without ritonavir) atazanavir/ritonavir atazanavir/cobicistat darunavir/ritonavir darunavir/cobicistat fosamprenavir (without ritonavir) fosamprenavir/ritonavir indinavir (without ritonavir) lopinavir/ritonavir ↓ atazanavir ↓ atazanavir ↔ etravirine ↓ atazanavir ↓ cobicistat ↓ etravirine ↓ cobicistat darunavir: effect unknown ↑ amprenavir ↑ amprenavir ↓ indinavir ↓ etravirine Co-administration of etravirine tablets and atazanavir without low- dose ritonavir is not recommended.
