Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting peptidoglycan cross-linking.
Ceftriaxone is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking, leading to cell lysis and death.
1-2 g IV/IM every 8 hours for moderate to severe infections; maximum 12 g/day.
Adult: 1-2 g IV or IM every 24 hours. Maximum 4 g/day for severe infections.

1.5-2 hours in adults with normal renal function; prolonged to 20-30 hours in end-stage renal disease (CrCl <10 mL/min).
Terminal half-life 6-9 hours in healthy adults; prolonged to 12-15 hours in elderly and up to 30 hours in severe renal impairment (CrCl <10 mL/min).
Renal: 80-90% unchanged via glomerular filtration and tubular secretion. Biliary/fecal: minimal (<5%).
Renal (33-67% unchanged), biliary (40-50% as active drug and metabolites), fecal (minor).
