Efavirenz + Lamivudine + Tenofovir Disoproxil Fumarate is an antiretroviral combination.
Efavirenz (EFV) is a component that directly clings to a certain enzyme involved in the replication of the HIV virus and blocks its action, thereby disrupting the multiplication of the virus within the body.
Lamivudine (3TC) is another component that transforms into an active form inside your cells, and this active form interferes with the copying process of the HIV virus. It does so by incorporating itself into the viral DNA, leading to a premature halt in its replication.
Tenofovir Disoproxil Fumarate (TDF) is also a component that transforms into an active form inside your body's cells. This active form competes with a natural substance that the HIV virus needs to replicate, causing a stop in the production of viral DNA.
