Duovir-N Tablets are a combination of three drugs namely zidovudine, lamivudine and Nevirapine that are commonly used in the management of the Human Immunodeficiency Virus (HIV) infection. Zidovudine and lamivudine belong to the nucleoside analogue class of antiretroviral drugs which act by terminating the growth of the DNA chain and inhibiting the reverse transcriptase (RT) of HIV. Nevirapine is a non-nucleoside reverse transcriptase inhibitor (NNRTI). It acts by directly inhibiting Reverse Transcriptase.
