CEFUROXIME AXETIL vs VANTIN
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.
Cefpodoxime proxetil is a semisynthetic third-generation cephalosporin antibiotic. It 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.
100-200 mg orally twice daily for 10-14 days for community-acquired pneumonia; 100 mg orally twice daily for 5-7 days for acute exacerbations of chronic bronchitis; 100 mg orally twice daily for 10 days for uncomplicated skin and skin structure infections; 100 mg orally twice daily for 3-7 days for uncomplicated urinary tract infections; 200 mg orally twice daily for 10 days for complicated urinary tract infections.

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.
The terminal elimination half-life in adults with normal renal function is about 2.2-2.8 hours. In children, it is approximately 1.5-2 hours. Prolonged half-life in renal impairment (up to 9-10 hours in severe impairment) requires dose adjustment.
Renal: 70-90% unchanged by glomerular filtration and tubular secretion; biliary/fecal: <10%
Approximately 80-90% of cefpodoxime is excreted unchanged in the urine within 24 hours, mainly by glomerular filtration and tubular secretion. A small fraction is eliminated via bile and feces.
