CEFTAROLINE FOSAMIL vs CEFTRIAXONE
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.
Ceftriaxone 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. It has broad-spectrum activity against gram-positive and gram-negative bacteria.

Clinical Note
moderateCeftriaxone + Probenecid
"The serum concentration of Probenecid can be increased when it is combined with Ceftriaxone."
Clinical Note
moderateCeftriaxone + Picosulfuric acid
"The therapeutic efficacy of Picosulfuric acid can be decreased when used in combination with Ceftriaxone."
Clinical Note
moderateWarfarin + Ceftriaxone
"Warfarin may increase the anticoagulant activities of Ceftriaxone."
Clinical Note
moderatePhenprocoumon + Ceftriaxone
Terminal elimination half-life is approximately 2.6 hours in patients with normal renal function. This supports twice-daily dosing in most infections.
Terminal half-life: 5.8-8.7 hours in adults; prolonged to 12-24 hours in neonates and 30-90 hours in severe renal impairment.
Renal excretion of unchanged ceftaroline accounts for approximately 88% of the administered dose. Biliary/fecal elimination is minimal (<6%).
Renal (33-67% unchanged) and biliary (up to 40%) with fecal elimination. In neonates, renal excretion is lower (~20%).
