Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Ceftazidime inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), primarily PBP-3, leading to cell lysis and death. It is a beta-lactam antibiotic with activity against Gram-negative bacteria including Pseudomonas aeruginosa.
1-2 g intravenously or intramuscularly every 24 hours. Maximum dose: 4 g daily.
1-2 g intravenously every 8 hours for most infections; up to 2 g every 6 hours for severe infections, particularly in neutropenic patients or those with cystic fibrosis.

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.
Terminal elimination half-life 1.7-2.0 hours in adults with normal renal function; prolonged to 12-30 hours in end-stage renal disease.
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.
Primarily renal (80-90% unchanged via glomerular filtration and tubular secretion); biliary/fecal excretion accounts for <1%.
