What are Anti-Retroviral Drugs (ARV)?

There are currently three major classes of ARV drugs: nucleoside or nucleotide analogue reverse transcriptase inhibitors (NRTIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs) and protease inhibitors (PIs). The difference between Anti-Retroviral (ARV) and Anti-Retroviral Therapy (ART) is that ARVs are drugs that have suppressive effect on HIV while ART is an anti HIV treatment using a combination of a minimum of at least three ARVs.
