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, 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.
Cefepime is a fourth-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby disrupting peptidoglycan cross-linking. It has enhanced activity against Gram-negative bacteria due to rapid penetration through the outer membrane and low affinity for β-lactamases.
1-2 g IV/IM every 8-12 hours; maximum 6 g/day.
1-2 g IV every 8-12 hours for most indications; maximum 2 g every 8 hours for severe infections.

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)
Terminal elimination half-life is approximately 2-2.5 hours in adults with normal renal function; extends to 8-12 hours in moderate renal impairment (CrCl 30-60 mL/min) and up to 20-24 hours in severe impairment (CrCl < 30 mL/min).
Primarily renal (80-90% unchanged) via glomerular filtration and tubular secretion; minor biliary/fecal (<10%)
Primarily renal (approximately 80-90% as unchanged drug) via glomerular filtration and tubular secretion; biliary/fecal excretion is minimal (< 1%).
