CEFTRIAXONE vs TAZIDIME
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), leading to cell lysis and death. It has broad-spectrum activity against gram-positive and gram-negative bacteria.
Ceftazidime inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and disrupting peptidoglycan cross-linking.
1-2 g IV/IM every 24 hours; maximum 4 g/day.
1 to 2 g IV/IM every 8 hours; maximum 6 g/day.

Terminal half-life: 5.8-8.7 hours in adults; prolonged to 12-24 hours in neonates and 30-90 hours in severe renal impairment.
Clinical Note
moderateCeftazidime + Probenecid
"The serum concentration of Probenecid can be increased when it is combined with Ceftazidime."

1.9 hours (range 1.5-2.8 hours); prolonged in renal impairment (up to 20 hours in ESRD).
Renal (33-67% unchanged) and biliary (up to 40%) with fecal elimination. In neonates, renal excretion is lower (~20%).
Primarily renal (80-90% unchanged via glomerular filtration), biliary/fecal <5%.
