Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Nucleoside reverse transcriptase inhibitor; phosphorylated to emtricitabine triphosphate which competes with endogenous deoxycytidine triphosphate and incorporates into viral DNA causing chain termination.
One tablet (dolutegravir 50 mg / abacavir 600 mg / lamivudine 300 mg) orally once daily.
200 mg orally once daily, typically in combination with other antiretroviral agents.

moderateEmtricitabine + Ribavirin
"Emtricitabine may increase the hepatotoxic activities of Ribavirin."

Clinical Note
moderateValganciclovir + Emtricitabine
abacavir: 1.5 hr; lamivudine: 5-7 hr; dolutegravir: 14 hr. Twice-daily dosing for abacavir/lamivudine, once-daily for dolutegravir
Terminal elimination half-life is approximately 10 hours (range 8–12 hours) in adults with normal renal function; prolonged to >20 hours in severe renal impairment (CrCl <30 mL/min).
abacavir: 83% renal (metabolites), 16% fecal; lamivudine: 70% renal (unchanged); dolutegravir: 64% fecal, 32% renal
Renal: approximately 86% of the dose is excreted unchanged in urine via glomerular filtration and active tubular secretion. Biliary/fecal: minimal (<14% as unchanged drug and metabolites in feces).
