CEFTRIAXONE SODIUM vs FORTAZ IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ceftriaxone inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and disrupting peptidoglycan cross-linking.
Ceftazidime inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically PBP3, thereby disrupting peptidoglycan cross-linking and leading to cell lysis. It is a third-generation cephalosporin with broad-spectrum activity against Gram-negative bacteria, including Pseudomonas aeruginosa.
1-2 g IV/IM every 12-24 hours; maximum 4 g/day.
1-2 g IV/IM every 8-12 hours; maximum 6 g/day.

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.
1.8 hours in normal adults; prolonged to 3-5 hours in neonates and 10-30 hours in severe renal impairment (CrCl <10 mL/min)
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.
Primarily renal (80-90% unchanged) via glomerular filtration and tubular secretion; minor biliary/fecal (<10%)
