CEFUROXIME AXETIL vs CEFZIL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefuroxime axetil is a prodrug that is hydrolyzed to cefuroxime, a second-generation cephalosporin antibiotic. It inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and disrupting peptidoglycan cross-linking.
Cefprozil inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting peptidoglycan cross-linking.
250–500 mg orally twice daily; for severe infections (e.g., pneumonia), 500 mg twice daily; for uncomplicated urinary tract infections, 250 mg twice daily; for Lyme disease, 500 mg twice daily for 20 days.
500 mg orally twice daily for 10 days; for uncomplicated skin infections, 250 mg twice daily or 500 mg once daily.

1.2-1.6 hours (normal renal function); prolonged to 15-22 hours in end-stage renal disease (CrCl <10 mL/min). For oral cefuroxime axetil, consider absorption and conversion to active cefuroxime.
1.2-1.5 hours in healthy adults; prolonged in renal impairment (e.g., up to 6-8 hours in severe renal failure)
Renal: 70-90% unchanged by glomerular filtration and tubular secretion; biliary/fecal: <10%
Renal: 80-91% unchanged in urine; biliary/fecal: minimal (<5%)
