CEFUROXIME AXETIL vs ZINACEF IN PLASTIC CONTAINER
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.
Cefuroxime is a second-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby blocking transpeptidation and 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.
750 mg intravenously or intramuscularly every 8 hours; for severe infections, 1.5 g intravenously every 8 hours.

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 is approximately 1.5 hours in adults with normal renal function; prolonged to 3-4 hours in neonates and up to 20-30 hours in end-stage renal disease.
Renal: 70-90% unchanged by glomerular filtration and tubular secretion; biliary/fecal: <10%
Approximately 80-90% of the dose is excreted unchanged in the urine via glomerular filtration and tubular secretion; the remainder is eliminated via bile and feces.
