KAFOCIN vs SUPRAX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Cefixime is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting peptidoglycan cross-linking. It has broad-spectrum activity against gram-positive and gram-negative bacteria.

Terminal elimination half-life: 4.5-6.5 hours (increased to 12-18 hours in severe renal impairment; CrCl <30 mL/min).
Terminal elimination half-life: 3-4 hours in normal renal function; prolonged to 11-15 hours in severe renal impairment (CrCl <20 mL/min).
Renal: 60-80% unchanged; biliary/fecal: 15-30% as metabolites; total clearance ~120 mL/min.
Renal: 50-55% unchanged in urine; biliary/fecal: 10-20% (biliary excretion); remainder metabolized or excreted via feces.
