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.
Cephalothin is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death. It has bactericidal activity against susceptible gram-positive and some gram-negative bacteria.

Terminal elimination half-life is approximately 2.6 hours in patients with normal renal function. This supports twice-daily dosing in most infections.
30-60 minutes in normal renal function; prolonged to 2-8 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%).
Primarily renal (60-70% unchanged) via glomerular filtration and tubular secretion; minor biliary (5-10%) and fecal (<1%) elimination.
