CEFOTAN vs FETROJA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefotetan is a cephamycin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting peptidoglycan cross-linking, and activating autolytic enzymes.
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 IV/IM every 12 hours for 5-10 days; up to 6 g/day for severe infections.
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: 4.5 hours (intravenous). In patients with renal impairment (CrCl <30 mL/min), half-life extends to approximately 20–30 hours, requiring dose adjustment.
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
Primarily renal (unchanged); ~88% excreted in urine within 24 hours. Biliary/fecal elimination is negligible (<1% as metabolites).
Renal: approximately 65-70% of the dose excreted unchanged in urine; biliary/fecal: minimal (<1%)
