CEFTAROLINE FOSAMIL vs CEFTIN
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.
Ceftin (cefuroxime axetil) is a second-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically transpeptidases, thereby disrupting peptidoglycan cross-linking. This leads to cell lysis and death primarily during active cell division.
600 mg IV every 12 hours infused over 1 hour
250-500 mg orally twice daily for 10 days; for community-acquired pneumonia, 500 mg twice daily for 10 days. Intravenous: 750-1500 mg 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: 1-2 hours (normal renal function); prolonged to 15-20 hours in severe renal impairment (CrCl <10 mL/min).
Renal excretion of unchanged ceftaroline accounts for approximately 88% of the administered dose. Biliary/fecal elimination is minimal (<6%).
Renal: 80-90% unchanged via glomerular filtration and tubular secretion; biliary/fecal: <5%.
