Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefotaxime is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically PBP-1A and PBP-3, 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/IM every 8 hours; maximum 12 g/day for severe infections.
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.

Terminal elimination half-life is 0.9-1.5 hours in adults with normal renal function; prolonged to 2.5-10 hours in renal impairment (CrCl <20 mL/min). In neonates, half-life is 3-6 hours.
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.
Renal (50-60% unchanged), biliary (5-10%), with approximately 20-30% metabolized to desacetylcefotaxime (also renally eliminated). Total renal elimination of parent drug and metabolite accounts for >80%.
Primarily renal (80-90% unchanged via glomerular filtration and tubular secretion); biliary/fecal excretion accounts for <1%.
