Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Bactericidal antibiotic that inhibits cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically inhibiting transpeptidase activity, leading to cell lysis.
1 gram intravenously over 3 hours every 8 hours in patients 18 years and older with creatinine clearance ≥ 60 mL/min.
250 mg orally every 6 hours for adults with normal renal function.

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
1.2-1.5 hours in normal renal function; prolonged in renal impairment (up to 10-20 hours in ESRD)
Renal: approximately 65-70% of the dose excreted unchanged in urine; biliary/fecal: minimal (<1%)
Primarily renal (80-90% unchanged by glomerular filtration and tubular secretion); remainder biliary/fecal (<10%)
