Mechanism of action

TDF (tenofovir disoproxil fumarate) and 3TC (lamivudine) are nucleoside reverse transcriptase inhibitors that block HIV reverse transcriptase, while EFV (efavirenz) is a non-nucleoside reverse transcriptase inhibitor that also targets the same enzyme through a different mechanism. Together, these three agents suppress HIV replication by preventing the conversion of viral RNA to DNA and integration into the host genome.
