Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ceftriaxone is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting peptidoglycan cross-linking. It has bactericidal activity against a broad range of gram-positive and gram-negative bacteria.
Cefiderocol is a cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), particularly PBP3, and is stable against a broad range of beta-lactamases, including carbapenemases, due to its ability to penetrate the outer membrane via the bacterial iron transport system.
1-2 g intravenously or intramuscularly every 24 hours. Maximum dose: 4 g daily.
1 gram intravenously over 3 hours every 8 hours in patients 18 years and older with creatinine clearance ≥ 60 mL/min.

Terminal elimination half-life is approximately 5.8-8.7 hours in adults, prolonged to 12-24 hours in elderly, and up to 30-72 hours in neonates. No dose adjustment in renal impairment alone; adjust in severe hepatic impairment.
Terminal elimination half-life: 2.5-3.5 hours; prolonged in renal impairment (e.g., up to 5-6 hours in severe renal impairment), requiring dose adjustment
Renal (33-67% unchanged) and biliary (up to 40% as unchanged drug and microbiologically inactive metabolites); fecal elimination of unabsorbed drug is minimal. Dose adjustment required in combined renal and hepatic impairment.
Renal: approximately 65-70% of the dose excreted unchanged in urine; biliary/fecal: minimal (<1%)
