CUBICIN vs KETEK
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.
Telithromycin binds to the 50S subunit of bacterial ribosome, inhibiting protein synthesis by blocking peptide chain elongation.
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.
Telithromycin 800 mg orally once daily for 7-10 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 half-life (t½) is 9.8–10.6 hours in young healthy adults, allowing once-daily dosing. In elderly or severe hepatic impairment, t½ may be prolonged.
Renal excretion of unchanged drug accounts for approximately 80% of the administered dose; minor fecal excretion (<5%) via biliary elimination.
Primarily fecal (≈70%) via biliary excretion of unchanged drug; renal excretion accounts for ≈13% (mostly unchanged), with additional minor metabolism (<30%).
