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.
Cefprozil inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting peptidoglycan cross-linking.
200 mg orally every 12 hours
500 mg orally twice daily for 10 days; for uncomplicated skin infections, 250 mg twice daily or 500 mg once daily.

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).
1.2-1.5 hours in healthy adults; prolonged in renal impairment (e.g., up to 6-8 hours in severe renal failure)
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.
Renal: 80-91% unchanged in urine; biliary/fecal: minimal (<5%)
