Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cephalosporin antibiotic; 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.
300 mg orally twice daily for 10 days; or 600 mg orally once daily for 10 days (for community-acquired pneumonia, acute exacerbations of chronic bronchitis, sinusitis, pharyngitis/tonsillitis, uncomplicated skin infections).
2 g intravenously every 8 hours for serious infections; 1 g intravenously every 8 hours for uncomplicated infections.

1.7 hours (range 1.2–2.3 h) in healthy adults; prolonged to 3.2–6.6 h in renal impairment (CrCl <30 mL/min); no significant change in hepatic impairment.
2 hours (prolonged to 4-12 hours in renal impairment; anuria: 20-30 hours).
Renal excretion as unchanged drug: 80-90% (primarily via glomerular filtration and tubular secretion); biliary/fecal: 10-20% (minor).
Primarily renal (80-90% unchanged via glomerular filtration and tubular secretion); biliary/fecal <10%.
