CUBICIN vs NEOBIOTIC
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.
NEOBIOTIC is a combination antibiotic product containing neomycin (aminoglycoside) and bacitracin (polypeptide antibiotic). Neomycin binds to the 30S ribosomal subunit of bacteria, causing misreading of mRNA and inhibiting protein synthesis. Bacitracin inhibits bacterial cell wall synthesis by interfering with dephosphorylation of the lipid carrier that transports peptidoglycan subunits.
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.
1 g intravenously every 12 hours.

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).
3.5–4.5 hours (terminal) in adults with normal renal function; prolonged 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.
Renal: 30–40% unchanged; fecal: 50–60% via biliary elimination; minimal hepatic metabolism.
