Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefoperazone is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
Ceftazidime inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), primarily PBP-3, leading to cell lysis and death. It is a beta-lactam antibiotic with activity against Gram-negative bacteria including Pseudomonas aeruginosa.
1-2 g IV every 6-8 hours; maximum 12 g/day.
1-2 g intravenously every 8 hours for most infections; up to 2 g every 6 hours for severe infections, particularly in neutropenic patients or those with cystic fibrosis.

0.5-1 hour in adults with normal renal function; prolonged to 2-8 hours in moderate to severe renal impairment (CrCl <30 mL/min).
Terminal elimination half-life 1.7-2.0 hours in adults with normal renal function; prolonged to 12-30 hours in end-stage renal disease.
Primarily renal (80-90% as unchanged drug via glomerular filtration and tubular secretion); biliary/fecal <10%.
