Tybost contains the active ingredient cobicistat.

Tybost is used to treat human immunodeficiency virus 1 (HIV-1) infection, the virus that causes acquired immunodeficiency syndrome (AIDS). It is used in adults and adolescents 12 years of age or older who are infected with HIV:

• who weigh at least 35 kg (when administered concomitantly with atazanavir 300 mg) or
• who weigh at least 40 kg (when administered concomitantly with darunavir 800 mg).

Tybost acts as abooster(potentiator) ofatazanavir or darunavir(both protease inhibitors) to help improve their effect (see section 3 of this leaflet).

Tybost does not directly treat HIV infection, but rather potentiates the levels of atazanavir and darunavirin the blood. It does this by delaying the degradation of atazanavir and darunavir, which will makethem remain in the body for a longer time.
