Definition
Nevirapine is an antiretroviral medication used to treat HIV (human immunodeficiency virus) infection. It belongs to a class of drugs called non-nucleoside reverse transcriptase inhibitors (NNRTIs). Nevirapine works by blocking the reverse transcriptase enzyme, which HIV needs to replicate. By inhibiting this enzyme, nevirapine helps to reduce the viral load in the body and slow the progression of HIV. It's a key part of HIV treatment regimens. Think of it as a roadblock for the virus. ๐
