CEFIZOX IN PLASTIC CONTAINER vs CEFTRIAXONE SODIUM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Binds to penicillin-binding proteins (PBPs) in bacterial cell wall, inhibiting peptidoglycan cross-linking, leading to cell lysis and death.
Ceftriaxone inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and disrupting peptidoglycan cross-linking.
1-2 g IV/IM every 8-12 hours; severe infections: up to 2 g every 6-8 hours; maximum 12 g/day.

1.5-2 hours; prolonged to 10-30 hours in severe renal impairment (CrCl <10 mL/min)
Terminal elimination half-life is 5.8-8.7 hours in adults with normal renal and hepatic function. In neonates, half-life is prolonged (up to 16 hours). In patients with renal impairment, half-life increases to 12-18 hours; in hepatic impairment, it may be 15-20 hours. Dose adjustment is not typically required unless both renal and hepatic impairment are present.
Primarily renal (80-90% unchanged), with biliary/fecal elimination being minor (<10%)
Ceftriaxone is eliminated 33-67% unchanged in urine via glomerular filtration and tubular secretion, and the remainder is excreted in feces (primarily as microbiologically inactive metabolites) via biliary secretion. Biliary excretion accounts for approximately 35-45% of total clearance.
