Abacavir/lamivudine and efavirenz

GlaxoSmithKline · FDA-approved active Small molecule

Abacavir/lamivudine and efavirenz is a Antiretroviral combination therapy (NRTI + NNRTI) Small molecule drug developed by GlaxoSmithKline. It is currently FDA-approved for HIV-1 infection in treatment-naïve and treatment-experienced patients.

This combination of three antiretroviral drugs inhibits HIV replication by blocking reverse transcriptase and integrase enzymes, preventing the virus from copying its genetic material and integrating into host cells.

Mechanism of action

Abacavir and lamivudine are nucleoside reverse transcriptase inhibitors (NRTIs) that compete with natural nucleotides to block HIV reverse transcriptase, while efavirenz is a non-nucleoside reverse transcriptase inhibitor (NNRTI) that directly binds and inhibits the same enzyme through a different mechanism. Together, these three agents provide complementary inhibition of viral replication at a critical step in the HIV life cycle.
