CUBICIN vs PYOCIDIN
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.
Pyocidin is a bactericidal antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing the attachment of aminoacyl-tRNA to the mRNA-ribosome complex.
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.
5 mg/kg intramuscular or subcutaneous every 24 hours. Max dose 300 mg per injection.

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 2-3 hours in patients with normal renal function; extends to 12-18 hours in severe renal impairment (CrCl <30 mL/min).
Renal excretion of unchanged drug accounts for approximately 80% of the administered dose; minor fecal excretion (<5%) via biliary elimination.
Primarily renal excretion of unchanged drug (60-70%), with 20-30% biliary excretion and minor fecal elimination (<10%).
