Dovato is the Brand name for the combination of two medications, such as dolutegravir and lamivudine. The US Food And Drugs Administration (FDA) has approved the treatment of HIV infection based on two drugs and a Single tablet Regime (STR).
It is used to control HIV infection. It helps reduce the amount of HIV in your body so that your immune system can function better. This reduces the likelihood of complications of HIV (for example, new infections, cancer) and improves the quality of life.
The drug Dovato, marketed by GlaxoSmithKline (GSK), has been reported as a complete regimen for the treatment of HIV-1 infection in adult patients with no history of antiretroviral treatment and no known or suspected substitutions associated with resistance to either dolutegravir or lamivudine.
Dolutegravir is an antiretroviral agent for HIV-1. It inhibits the integrase of HIV by binding to the active site and blocking the step of transferring the retroviral DNA integration filament into the host cell. The filament transfer phase is essential in the HIV replication cycle and leads to the inhibition of virus activity.
Lamivudine is a synthetic nucleoside analog and is intracellular phosphorylated to its active metabolite, lamivudine triphosphate (L-TP), 5′-triphosphate. This nucleoside analog is incorporated into the viral DNA by HIV reverse transcriptase and HBV polymerase, resulting in the termination of the DNA chain.
