Lamivudine + Nevirapine + Zidovudine
Uses of Lamivudine + Nevirapine + Zidovudine
Lamivudine + Nevirapine + Zidovudine is a fixed-dose antiretroviral combination used to manage HIV-1 infection in adults and adolescents weighing 30 kg or more.
This combination is commonly used for:
• HIV-1 infection: Reduces the amount of virus in the blood by acting on the virus at different stages of its replication cycle.
• Long-term HIV management: Used as part of ongoing antiretroviral therapy to help maintain low viral load and preserve immune function.
• Combination antiretroviral therapy: Reduces the likelihood of the virus becoming resistant to treatment when compared with using a single antiretroviral agent.

How Lamivudine + Nevirapine + Zidovudine works
Lamivudine + Nevirapine + Zidovudine works by attacking the human immunodeficiency virus (HIV) at more than one point in its life cycle, helping to reduce the amount of virus in the body.
Lamivudine and Zidovudine both belong to a class of medicines called nucleoside reverse transcriptase inhibitors (NRTIs). Inside infected cells, they are converted into active forms that resemble the natural building blocks of viral DNA. When the virus tries to copy itself, these medicines get incorporated into the new viral DNA and stop it from being completed, halting the virus from multiplying.
Nevirapine is a non-nucleoside reverse transcriptase inhibitor (NNRTI). It works differently by binding directly to reverse transcriptase, an enzyme the virus needs to convert its genetic material into DNA. This blocks the enzyme's activity and prevents the virus from replicating.
Together, these three medicines attack the virus through different mechanisms, reducing the chance of the virus becoming resistant and helping to keep the viral load low over the long term.
