CEFUROXIME AXETIL vs CEPHRADINE
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.
Cephradine is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
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.
250-500 mg orally every 6 hours; 500 mg to 1 g intramuscularly or intravenously every 6 hours. Maximum: 4 g/day.

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.
Terminal elimination half-life 0.5–1.5 hours (normal renal function); prolonged to 6–15 hours in severe renal impairment (CrCl <10 mL/min).
Renal: 70-90% unchanged by glomerular filtration and tubular secretion; biliary/fecal: <10%
Primarily renal (≥90% unchanged via glomerular filtration and tubular secretion); minor biliary/fecal (<10%).
