CEFIZOX vs KEFZOL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefizox (ceftizoxime) is a third-generation cephalosporin that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting transpeptidation and autolysin inhibition.
Cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting peptidoglycan cross-linking.
1-2 g IV/IM every 8-12 hours; maximum 12 g/day for severe infections.
1-2 g IV/IM every 8 hours for moderate to severe infections; maximum 12 g/day.

1.7-1.9 hours in adults; prolonged to 15-25 hours in severe renal impairment (CrCl <10 mL/min)
1.5-2 hours in adults with normal renal function; prolonged to 20-30 hours in end-stage renal disease (CrCl <10 mL/min).
Primarily renal (90-95% unchanged via glomerular filtration and tubular secretion); biliary (<1%); fecal (minimal)
Renal: 80-90% unchanged via glomerular filtration and tubular secretion. Biliary/fecal: minimal (<5%).
