KAFOCIN vs SEFFIN
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.
SEFFIN is a brand name for cefazolin, a first-generation cephalosporin antibiotic. It inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death. It is bactericidal against susceptible organisms.

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 is approximately 0.5-1 hour in adults with normal renal function; prolonged to 20-40 hours in severe renal impairment (CrCl <10 mL/min).
Renal: 60-80% unchanged; biliary/fecal: 15-30% as metabolites; total clearance ~120 mL/min.
Primarily renal (80-90% unchanged) via glomerular filtration and tubular secretion; minor biliary excretion (<5%) and fecal elimination.
