Mechanism of action

An enzyme HIV-1 protease is required for the proteolytic gap of the viral polyprotein precursors integrate to the individual functional proteins form in HIV-1 infectious. Indinavir add to the protease active site and inhibits the activity of the enzyme. This barrierprohibitscleavage of the viral polyproteins causing in the formation of immature non-infectious viral particles.
