How Does Non Nucleoside Reverse Transcriptase Inhibitors Work

Non-nucleoside reverse transcriptase inhibitors (NNRTIs) bind to and block HIV 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.

How does reverse transcriptase inhibitor work?

Mechanism of action Reverse transcriptase inhibitors are active against HIV, a retrovirus. The drugs inhibit RNA virus replication by reversible inhibition of viral HIV reverse transcriptase, which reverse transcribes viral RNA into DNA for insertion into the host DNA sequence (see Fig. 51.6).

What is considered a non-nucleoside reverse transcriptase inhibitor?

Non-nucleoside reverse transcriptase inhibitors (NNRTIs) are antiviral agents that bind non-competitively to HIV-1’s reverse transcriptase and prevents viral RNA conversion to DNA. They are used to treat human immunodeficiency virus (HIV infection) and acquired immune deficiency syndrome (AIDS).
