Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bactericidal; inhibits cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and autolysin activation.
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.
1-2 g IV/IM every 6 hours for moderate to severe infections; maximum 12 g/day.
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.

30-60 minutes in adults with normal renal function; prolonged to 10-20 hours in end-stage renal disease. Requires dose adjustment for CrCl <30 mL/min.
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.
Renal: 90-95% unchanged via glomerular filtration and tubular secretion. Biliary: <1%. Fecal: minimal.
Renal: 70-90% unchanged by glomerular filtration and tubular secretion; biliary/fecal: <10%
