Darunavir is a protease inhibitor, which means it blocks a protein called protease. Normally, protease helps process viral proteins so that HIV can infect healthy cells.

It slows down your body from breaking down other HIV ARVs like darunavir. This “boosts” the levels of darunavir and other HIV ARVs in the body. It also makes them last longer in the body. This helps darunavir and other HIV ARVs work better to fight the infection.
