Antiretroviral drugs work by targeting specific stages in the HIV life cycle. For instance, NRTIs and NNRTIs inhibit the action of reverse transcriptase, an enzyme necessary for the viral RNA to convert into DNA. Protease Inhibitors block the protease enzyme, preventing the maturation of viral particles. Integrase Inhibitors, on the other hand, block the integration of viral DNA into the host's genome. By intervening at different stages, these drugs collectively inhibit the proliferation of the virus.
