CEFMAX vs CEFOXITIN IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
CEFMAX (cefepime) is a fourth-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically PBP-3 in Gram-negative bacteria and PBP-1a/1b in Gram-positive bacteria, thereby disrupting peptidoglycan cross-linking and leading to cell lysis. It has zwitterionic properties facilitating rapid penetration through Gram-negative outer membranes and is relatively resistant to hydrolysis by many beta-lactamases, including AmpC beta-lactamases.
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.

2–4 hours in adults with normal renal function; prolonged to 20–40 hours in severe renal impairment (CrCl <10 mL/min).
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).
Primarily renal (80–90% unchanged via glomerular filtration and tubular secretion); biliary/fecal elimination accounts for <5%.
Renal: 85-95% unchanged via glomerular filtration and tubular secretion; biliary: <2%; fecal: trace.
