Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ceftizoxime is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death. It has broad-spectrum activity against gram-positive and gram-negative bacteria.
Ceftriaxone is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
1-2 g IV every 8-12 hours; maximum 12 g/day
1-2 g IV or IM once daily; maximum 4 g/day. For serious infections, 2 g IV every 12 hours.

1.5–2 hours in normal renal function; extends to 20–30 hours in ESRD. Dose adjustment required for CrCl <50 mL/min.
Terminal elimination half-life: 6-8 hours in adults with normal renal function; prolonged up to 15 hours in elderly; significantly increased in renal impairment (up to 20-30 hours in ESRD).
Renal: 80–90% unchanged via glomerular filtration and tubular secretion. Biliary/fecal: <10%.
Renal (33-67% unchanged) and biliary (40-50% unchanged and microbiologically inactive metabolite). Approximately 50% excreted in urine, 50% in feces.
