Duovir-N tablets contain a combination of the active ingredients nevirapine (200mg) lamivudine (150mg) and zidovudine (300mg), which are antiretroviral drugs that are used to treat HIV infection.
Duovir-N is a fixed dose combination treatment for Human Immunodeficiency Virus (HIV) infection in adults. Duovir-N tablets are used to treat HIV patients who have already been treated with other HIV medications and have responded well to each of the drugs in the combination; and are also able to tolerate each of these medications, at the recommended doses without requiring a dose adjustment due to low weight. HIV impairs the immune system by attacking specific immune cells called CD4+ cells that are involved in fighting infection, and this can lead to opportunistic life-threatening infection (infections that would not normally be harmful); also if too many CD4+ cells are destroyed this can result in acquired immune deficiency syndrome (AIDS). Duovir-N tablets prevent or slow down the ability of HIV to replicate and spread, which keeps the amount of virus (viral load) down to a low level; allowing the numbers of CD4+ cells to increase, so that the immune system can recover, reducing the risk of disease progression.
