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 AntiRetroViral (ARV) and AntiRetroviral 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.
