Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefoperazone, a third-generation cephalosporin, inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting peptidoglycan cross-linking, and activating autolytic enzymes.
Cefoxitin inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically PBP1a, PBP1b, and PBP2, thereby inhibiting transpeptidation and leading to cell lysis. It is a cephamycin antibiotic resistant to beta-lactamase hydrolysis due to a 7-alpha-methoxy group.

2.2 hours (normal renal function); prolonged to 4-5 hours in elderly or hepatic impairment; in severe renal failure (CrCl <10 mL/min), may extend up to 8 hours.
Terminal elimination half-life: 0.7-1.5 hours (approximately 45-90 minutes); prolonged to 2-6 hours in moderate renal impairment (CrCl 30-50 mL/min) and up to 10-20 hours in severe renal impairment (CrCl <10 mL/min).
Renal: 65-85% unchanged; biliary: 10-20% (fecal elimination); total renal clearance approximates glomerular filtration rate.
Renal: 85-95% unchanged via glomerular filtration and tubular secretion; biliary: <2%; fecal: trace.
