CEFTAROLINE FOSAMIL vs ZINACEF IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ceftaroline fosamil is a prodrug that is converted to the active metabolite ceftaroline. Ceftaroline inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), including PBP2a in MRSA and PBP2x in Streptococcus pneumoniae, thereby preventing cross-linking of peptidoglycan.
Cefuroxime is a second-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby blocking transpeptidation and leading to cell lysis and death.
600 mg IV every 12 hours infused over 1 hour
750 mg intravenously or intramuscularly every 8 hours; for severe infections, 1.5 g intravenously every 8 hours.

Terminal elimination half-life is approximately 2.6 hours in patients with normal renal function. This supports twice-daily dosing in most infections.
Terminal elimination half-life is approximately 1.5 hours in adults with normal renal function; prolonged to 3-4 hours in neonates and up to 20-30 hours in end-stage renal disease.
Renal excretion of unchanged ceftaroline accounts for approximately 88% of the administered dose. Biliary/fecal elimination is minimal (<6%).
Approximately 80-90% of the dose is excreted unchanged in the urine via glomerular filtration and tubular secretion; the remainder is eliminated via bile and feces.
