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. Lamivudine and tenofovir disoproxil fumarate are nucleoside reverse transcriptase inhibitors (NRTIs) that inhibit HIV-1 reverse transcriptase by competing with natural substrates and causing chain termination.
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.

Dolutegravir: ~14 hours (range 11-18) in HIV-1-infected adults, supports once-daily dosing. Lamivudine: ~18-19 hours in HIV-infected adults, allows once-daily dosing; prolonged in renal impairment. Tenofovir disoproxil fumarate: ~17 hours (tenofovir) in HIV-infected adults, supports once-daily dosing; extended in renal impairment.
abacavir: 1.5 hr; lamivudine: 5-7 hr; dolutegravir: 14 hr. Twice-daily dosing for abacavir/lamivudine, once-daily for dolutegravir
Dolutegravir: ~64% feces (as unchanged drug), 31% urine (as unchanged and metabolites). Lamivudine: ~70% urine (as unchanged drug) via active tubular secretion, ~6% as inactive trans-sulfoxide metabolite. Tenofovir disoproxil fumarate: ~70-80% urine (as unchanged tenofovir) via glomerular filtration and active tubular secretion.
abacavir: 83% renal (metabolites), 16% fecal; lamivudine: 70% renal (unchanged); dolutegravir: 64% fecal, 32% renal
