Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dolutegravir is an HIV-1 integrase strand transfer inhibitor (INSTI) that blocks the integration of HIV-1 DNA into host genomic DNA. Emtricitabine is a nucleoside reverse transcriptase inhibitor (NRTI) that inhibits HIV-1 reverse transcriptase by competing with the natural substrate and causing chain termination. Tenofovir alafenamide is an NRTI that is converted to tenofovir, which inhibits HIV-1 reverse transcriptase after phosphorylation.
Dolutegravir is an HIV integrase strand transfer inhibitor that blocks integration of HIV-1 DNA into host cell DNA. Abacavir and lamivudine are nucleoside reverse transcriptase inhibitors that inhibit HIV-1 reverse transcriptase via incorporation into viral DNA, causing chain termination.
One tablet (dolutegravir 50 mg; emtricitabine 200 mg; tenofovir alafenamide 25 mg) orally once daily.
One tablet (dolutegravir 50 mg / abacavir 600 mg / lamivudine 300 mg) orally once daily.
