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.
Cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking.
1-2 g IV/IM every 12-24 hours; maximum 4 g/day.
1 g intramuscularly or intravenously every 24 hours; for severe infections, 2 g every 24 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: 4-5 hours (prolonged to 12-24 hours in severe renal impairment; dosing adjustment recommended for CrCl <50 mL/min).
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.
Renal: ~90% unchanged in urine via glomerular filtration and tubular secretion; biliary/fecal: ~5% (cefonicid undergoes minimal hepatic metabolism; ~4% excreted in feces as parent drug and metabolites).
