Lamivudine / Abacavir Sulfate
Lamivudine and abacavir are nucleoside reverse transcriptase inhibitors (NRTIs) that block HIV reverse transcriptase, preventing viral replication by terminating DNA chain elongation.
Lamivudine and abacavir are nucleoside reverse transcriptase inhibitors (NRTIs) that block HIV reverse transcriptase, preventing viral replication by terminating DNA chain elongation. Used for HIV-1 infection in treatment-naïve and treatment-experienced patients, Part of combination antiretroviral therapy (cART) regimens.
At a glance
| Generic name | Lamivudine / Abacavir Sulfate |
|---|---|
| Sponsor | GlaxoSmithKline |
| Drug class | Nucleoside reverse transcriptase inhibitor (NRTI) combination |
| Target | HIV reverse transcriptase |
| Modality | Small molecule |
| Therapeutic area | Infectious Disease / Virology |
| Phase | FDA-approved |
Mechanism of action
Both drugs are nucleoside analogs that compete with natural nucleotides for incorporation into the growing HIV DNA chain during reverse transcription. Once incorporated, they cause chain termination because they lack a 3'-OH group needed for further DNA synthesis. This combination targets the same enzyme but provides synergistic activity and helps reduce the emergence of drug-resistant viral strains.
