CEFTAROLINE FOSAMIL vs PRECEF
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.
Cefoperazone is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.

1-2 g IV every 6-8 hours; maximum 12 g/day.

Terminal elimination half-life is approximately 2.6 hours in patients with normal renal function. This supports twice-daily dosing in most infections.
0.5-1 hour in adults with normal renal function; prolonged to 2-8 hours in moderate to severe renal impairment (CrCl <30 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% as unchanged drug via glomerular filtration and tubular secretion); biliary/fecal <10%.
