Treating HIV infection in certain patients along with other antiretroviral medicines. Duovir (Lamivudine-Zidovudine) must always be taken along with another medicine called ritonavir. Duovir (Lamivudine-Zidovudine tablets) is an HIV protease inhibitor. It works by blocking the growth of HIV.
Mechanism of action:
Duovir (Lamivudine 150mg and Zidovudine 300 mg) is a HIV protease inhibitor which prevents HIV replication by binding to the enzyme's active site, thereby preventing the dimerization and the catalytic activity of the HIV-1 protease. Duovir (Lamivudine-Zidovudine) selectively inhibits the cleavage of HIV encoded Gag-Pol polyproteins in virus-infected cells, which prevents the formation of mature infectious virus particles. Structual analyses suggests that the close contact that Duovir (Lamivudine-Zidovudine) has with the main chains of the protease active site amino acids (Asp-29 and Asp-30) is an important contributing factor to its potency and wide spectrum of activity against multi-protease inhibitor resistant HIV-1 variants. Duovir (Lamivudine-Zidovudine) can also adapt to the changing shape of a protease enzyme because of its molecular flexibility. Duovir (Lamivudine-Zidovudine) is known to bind to two distinct sites on the enzyme: the active site cavity and the surface of one of the flexible flaps in the protease dimer.
Dosage and Administration:
Use Duovir as directed by your doctor. Check the label on the medicine for exact dosing instructions.
