Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefazolin is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and disrupting peptidoglycan cross-linking. This leads to cell lysis and death, primarily in actively dividing bacteria.
Ceftriaxone is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting peptidoglycan cross-linking. It has bactericidal activity against a broad range of gram-positive and gram-negative bacteria.
For uncomplicated infections: 1-2 g IV every 8 hours. For severe infections: up to 2 g IV every 4 hours. Administered as an IV infusion over 30-60 minutes.
1-2 g intravenously or intramuscularly every 24 hours. Maximum dose: 4 g daily.

1.8 hours (normal renal function); prolonged to 10-30 hours in severe renal impairment (CrCl <10 mL/min)
Terminal elimination half-life is approximately 5.8-8.7 hours in adults, prolonged to 12-24 hours in elderly, and up to 30-72 hours in neonates. No dose adjustment in renal impairment alone; adjust in severe hepatic impairment.
Renal: >80% unchanged via glomerular filtration and tubular secretion; biliary/fecal: <1%
Renal (33-67% unchanged) and biliary (up to 40% as unchanged drug and microbiologically inactive metabolites); fecal elimination of unabsorbed drug is minimal. Dose adjustment required in combined renal and hepatic impairment.
