Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefpodoxime proxetil is a prodrug that is de-esterified in vivo to cefpodoxime, a third-generation cephalosporin antibiotic. It inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation, and disrupting peptidoglycan cross-linking, leading to cell lysis. It has broad-spectrum activity against Gram-positive and Gram-negative bacteria.
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.
200 mg orally every 12 hours
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 of cefpodoxime is 2.2-2.8 hours in healthy adults; prolonged to 5.9-9.8 hours in moderate renal impairment (CrCl 10-30 mL/min) and up to 13-14 hours in severe impairment (CrCl <10 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.
Renal excretion of unchanged drug (29-33%) and fecal/biliary elimination of inactive metabolites; 80% of radiolabeled dose recovered in urine and feces over 8 days.
Primarily renal (80-90% unchanged via glomerular filtration and tubular secretion); biliary/fecal excretion accounts for <1%.
