HIV and AIDS: Antiretroviral Drugs, Treatments and Medications (cont.)

Protease Inhibitors (PIs)

PIs block the action of an HIV enzyme called protease that allows HIV to produce infectious copies of itself within HIV-infected human cells. Thus, blocking protease prevents HIV in already-infected cells from producing HIV that can infect other, not yet infected cells.
