Mechanism of action
Tenofovir is a nucleotide reverse transcriptase inhibitor, lamivudine is a nucleoside reverse transcriptase inhibitor, and efavirenz is a non-nucleoside reverse transcriptase inhibitor. Together, they target different aspects of HIV reverse transcription and viral replication, reducing viral load and slowing disease progression in HIV-infected patients.
Approved indications
