How do NNRTI work?
NNRTIs work by binding to the HIV enzyme called reverse transcriptase, which is essential to the viral replication process, and therefore blocking HIV from making copies of itself. Dapivirine is an example of an NNRTI. NRTIs work by mimicking nucleotides that are the building blocks of viral DNA.
What is the difference between NNRTI and Nrti?
The NNRTIs differ from the NRTIs in that they do not have a nucleoside structure and do not depend on phosphorylation for activity. They function as noncompetitive substrate analogues and are selective inhibitors of HIV-1, with no activity against HIV-2 strains or even HIV-1 type O.

What is NNRTI in HIV?
Non-nu cleoside reverse transcriptase inhibitors (NNRTIs) are one of the classes of drugs that form part of the antiretroviral therapy (ART) for human immunodeficiency virus (HIV) infection. An NNRTI drug may be part of a cocktail of ART drugs that each target HIV at different points in its replication cycle to help lower the level of virus in the body and prevent HIV from causing AIDS (acquired immunodeficiency syndrome). AIDS may lead to death from secondary infections after immune system collapse.
What is a nucleoside transcriptase inhibitor?
The nucleoside transcriptase inhibitors (NRTIs), have a nucleoside that is structurally similar to the T-cell DNA’s nucleoside. Mimicking the T-cell enables the NRTIs to integrate with the T-cell DNA and stop the production of viral DNA proteins. The non-nucleoside transcriptase inhibitors do not get into the cell nucleus or interfere with the DNA.
What is the treatment for HIV?
