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.
Ceftazidime is a third-generation cephalosporin that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically PBP-3, leading to cell lysis and death.
1 gram intravenously over 3 hours every 8 hours in patients 18 years and older with creatinine clearance ≥ 60 mL/min.
2 g intravenously every 8 hours for serious infections; 1 g intravenously every 8 hours for uncomplicated infections.

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
2 hours (prolonged to 4-12 hours in renal impairment; anuria: 20-30 hours).
Renal: approximately 65-70% of the dose excreted unchanged in urine; biliary/fecal: minimal (<1%)
Primarily renal (80-90% unchanged via glomerular filtration and tubular secretion); biliary/fecal <10%.
