CUBICIN vs PROLOPRIM
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.
Inhibits bacterial dihydrofolate reductase (DHFR), blocking the conversion of dihydrofolic acid to tetrahydrofolic acid, thereby inhibiting bacterial DNA, RNA, and protein synthesis.
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.
100 mg orally twice daily or 200 mg orally once daily.

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 8-10 hours in normal renal function; prolonged (>20 hours) in significant renal impairment.
Renal excretion of unchanged drug accounts for approximately 80% of the administered dose; minor fecal excretion (<5%) via biliary elimination.
Primarily renal (80-90% as unchanged drug); less than 5% as metabolites; fecal excretion negligible.
