CEFTAROLINE FOSAMIL vs DURICEF
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.
Cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking.
600 mg IV every 12 hours infused over 1 hour
500 mg to 1 g orally once or twice daily.

Terminal elimination half-life is approximately 2.6 hours in patients with normal renal function. This supports twice-daily dosing in most infections.
1.5-2 hours (prolonged to 20-30 hours in severe renal impairment; dosing adjustment required for CrCl <50 mL/min).
Renal excretion of unchanged ceftaroline accounts for approximately 88% of the administered dose. Biliary/fecal elimination is minimal (<6%).
Primarily renal (80-90% unchanged via glomerular filtration and tubular secretion); <10% biliary/fecal.
