Product Description

Efavirenz is a first-line NNRTI used in combination antiretroviral therapy (ART) for HIV-1 infection. It is widely used globally due to once-daily dosing and high efficacy in viral load suppression.

How Efavirenz Works

Efavirenz works by non-competitively inhibiting HIV-1 reverse transcriptase (RT). It binds to a specific allosteric site on the enzyme, which stops the virus from making DNA. This way, HIV-1 cannot replicate, but it doesn’t affect human DNA polymerases, so our own cells are mostly safe.
