FUZEON vs INCIVEK
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fusion inhibitor; binds to gp41 of HIV-1, preventing conformational changes required for fusion with host CD4+ T-cell membrane.
Inhibitor of the HCV NS3/4A serine protease, preventing cleavage of the HCV polyprotein, thereby inhibiting viral replication.
90 mg subcutaneously twice daily
Incivek (telaprevir) is administered orally at a dose of 750 mg (two 375 mg tablets) three times daily (every 7-9 hours) with food (not low-fat).

Terminal elimination half-life: 3.8 hours; clinically, steady-state plasma concentrations are achieved within 2-3 days with subcutaneous administration
Terminal elimination half-life ranges from 4 to 13 hours (mean ~7 hours) in healthy volunteers; prolonged to 10-20 hours in HCV-infected patients.
Renal: approximately 70% as unchanged drug via glomerular filtration; fecal: <5% as metabolites
Approximately 91% of the radiolabeled dose is recovered in feces (79% as unchanged drug) and 9% in urine (1% as unchanged drug).
