CEFTAZIDIME SODIUM IN PLASTIC CONTAINER vs CEFTRIAXONE SODIUM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ceftazidime inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically PBP3, inhibiting transpeptidase activity and disrupting peptidoglycan cross-linking, leading to cell lysis and death.
Ceftriaxone inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and disrupting peptidoglycan cross-linking.
1-2 g IV every 8 hours for pseudomonal infections; 500 mg to 1 g IV every 8-12 hours for uncomplicated UTIs.
1-2 g IV/IM every 12-24 hours; maximum 4 g/day.

1.5–2.0 hours in normal renal function; prolonged to 15–30 hours in ESRD.
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.
Primarily renal (80–90% unchanged via glomerular filtration); biliary/fecal <1%.
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.
