Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ceftriaxone inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and disrupting peptidoglycan cross-linking.
Cefuroxime is a second-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby blocking transpeptidation and leading to cell lysis and death.
1-2 g IV/IM every 12-24 hours; maximum 4 g/day.
750 mg intravenously or intramuscularly every 8 hours; for severe infections, 1.5 g intravenously every 8 hours.

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.
Terminal elimination half-life is approximately 1.5 hours in adults with normal renal function; prolonged to 3-4 hours in neonates and up to 20-30 hours in end-stage renal disease.
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.
Approximately 80-90% of the dose is excreted unchanged in the urine via glomerular filtration and tubular secretion; the remainder is eliminated via bile and feces.
