Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking.
Ceftazidime is a third-generation cephalosporin that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically PBP-3, leading to cell lysis and death.
1-2 g IV/IM every 8-12 hours; maximum 6 g/day.
2 g intravenously every 8 hours for serious infections; 1 g intravenously every 8 hours for uncomplicated infections.

Terminal elimination half-life is 1.5-2 hours; prolonged to 3-5 hours in moderate renal impairment (CrCl 30-50 mL/min) and up to 10-20 hours in severe impairment (CrCl <10 mL/min); dosing adjustment required for CrCl <50 mL/min.
2 hours (prolonged to 4-12 hours in renal impairment; anuria: 20-30 hours).
Approximately 80-90% renal excretion as unchanged drug via glomerular filtration and tubular secretion; 10-20% biliary/fecal elimination.
Primarily renal (80-90% unchanged via glomerular filtration and tubular secretion); biliary/fecal <10%.
