Mechanism of action

Lamivudine and zidovudine are both nucleoside analogs that inhibit HIV reverse transcriptase, the enzyme the virus uses to convert its RNA genome into DNA for integration into host cells. By competing with natural nucleotides, they cause chain termination during viral DNA synthesis, effectively blocking HIV replication. The combination provides synergistic antiviral activity and is used as part of combination antiretroviral therapy.
