CEFMAX vs KAFOCIN
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.
KAFOCIN (cefepime/enmetazobactam) is a combination of a fourth-generation cephalosporin (cefepime) and a β-lactamase inhibitor (enmetazobactam). Enmetazobactam inhibits extended-spectrum β-lactamases (ESBLs) and other class A β-lactamases, restoring cefepime's activity against β-lactamase-producing bacteria. Cefepime inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell death.

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: 4.5-6.5 hours (increased to 12-18 hours in severe renal impairment; CrCl <30 mL/min).
Primarily renal (80–90% unchanged via glomerular filtration and tubular secretion); biliary/fecal elimination accounts for <5%.
Renal: 60-80% unchanged; biliary/fecal: 15-30% as metabolites; total clearance ~120 mL/min.
