Duovir Tablets (Lamivudine Zidovudine) is a combination of two active ingredients namely Duovir Tablets, both components are active against the Human Immunodeficiency Virus (HIV) and inhibit the activity of reverse transcriptase blocking the production of DNA and new viruses. Separately Duovir Tablets may not be so effective as their combination which makes it more difficult for HIV to produce high resistant strains.
How it works?
Lamivudine belongs to a class of medication called nucleoside reverse transcriptase inhibitors. It decreases the amount of virus (HIV and hepatitis) in the blood. It also increases the number of infection fighting cells in the body (CD4 cells). It does not cure HIV completely but reduces the chances of getting acquired immunodeficiency syndrome (AIDS) and HIV related infections or cancer.
Zidovudine belongs to a group of medications called nucleoside analogue reverse transcriptase inhibitors (NRTIs), also known as antiretrovirals. Zidovudine does not cure HIV infection; it reduces the amount of viruses in the body by inhibiting the enzyme (viral reverse transcriptase) which is essential for the virus to grow. Further, zidovudine also increases some white blood cells (CD4 cells) of the body that are important in fighting infections.
