CUBICIN vs VIBATIV
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cubicin is a lipopeptide antibiotic that binds to bacterial cell membranes, causing rapid depolarization and inhibition of protein, DNA, and RNA synthesis, leading to bacterial cell death.
Lipoglycopeptide antibiotic that inhibits cell wall synthesis by binding to the D-Ala-D-Ala terminus of peptidoglycan precursors, blocking transglycosylation and transpeptidation. Also disrupts membrane potential and increases membrane permeability.
4-6 mg/kg IV once daily for complicated skin infections; 6 mg/kg IV once daily for Staphylococcus aureus bloodstream infections (including right-sided endocarditis); infuse over 2 minutes or 30 minutes.
10 mg/kg intravenously once every 24 hours, infused over 60 minutes for 7 to 14 days.

Terminal elimination half-life is about 8-9 hours (mean 8.1 hours) in patients with normal renal function; prolonged to 27-35 hours in severe renal impairment (CrCl <30 mL/min).
Terminal elimination half-life is approximately 177 hours (7.4 days), supporting once-daily dosing.
Renal excretion of unchanged drug accounts for approximately 80% of the administered dose; minor fecal excretion (<5%) via biliary elimination.
Primarily renal excretion as unchanged drug (approximately 93% of dose recovered in urine; <5% in feces).
