Nucleoside Reverse Transcriptase Inhibitor (NRTI)
Nucleoside Analogue Reverse Transcriptase Inhibitor
Antiretroviral (ARV) HIV drug class. Nucleoside reverse transcriptase inhibitors (NRTIs) block reverse transcriptase (an HIV enzyme). HIV uses reverse transcriptase to convert its RNA into DNA (reverse transcription). Blocking reverse transcriptase and reverse transcription prevents HIV from replicating.
