CEFIZOX vs ROCEPHIN
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.
Ceftriaxone inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby interfering with peptidoglycan cross-linking and leading to cell lysis.
1-2 g IV/IM every 8-12 hours; maximum 12 g/day for severe infections.
1-2 g IV or IM every 24 hours; maximum 4 g/day for serious infections.

1.7-1.9 hours in adults; prolonged to 15-25 hours in severe renal impairment (CrCl <10 mL/min)
Terminal half-life ~6-8 hours in adults with normal renal function; prolonged to 12-24 hours in neonates and elderly.
Primarily renal (90-95% unchanged via glomerular filtration and tubular secretion); biliary (<1%); fecal (minimal)
Renal (33-67%) and biliary (40-50%); primarily excreted unchanged. Dual elimination: ~50% renal, ~50% biliary/fecal.
