CEFTAROLINE FOSAMIL vs ULTRACEF
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.
Cefadroxil, a first-generation cephalosporin, inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and disrupting peptidoglycan cross-linking, leading to cell lysis. It is bactericidal against susceptible organisms.
600 mg IV every 12 hours infused over 1 hour
250 mg orally every 6 hours or 500 mg orally every 12 hours for uncomplicated urinary tract infections; 1 g orally every 12 hours for complicated urinary tract infections.

Terminal elimination half-life is approximately 2.6 hours in patients with normal renal function. This supports twice-daily dosing in most infections.
0.5–1.2 hours in normal renal function; prolonged to 2–4 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%).
Approximately 90% of an oral dose is excreted unchanged in urine via glomerular filtration and tubular secretion; less than 1% is excreted in feces via biliary elimination.
