CEFOXITIN IN PLASTIC CONTAINER vs CEPHALOTHIN SODIUM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Cephalothin is a first-generation cephalosporin with bactericidal activity by inhibiting bacterial cell wall synthesis via binding to penicillin-binding proteins (PBPs).

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).
Terminal elimination half-life: 0.5-1.0 hour in adults with normal renal function. In anuria, prolonged to 2.5-8 hours. Dose adjustment required for CrCl <50 mL/min.
Renal: 85-95% unchanged via glomerular filtration and tubular secretion; biliary: <2%; fecal: trace.
Primarily renal (60-90% unchanged via glomerular filtration and tubular secretion). Minor biliary excretion (1-5%). Fecal elimination negligible.
