CEFUROXIME AXETIL vs KEFLET
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.
Keflet (warfarin) inhibits vitamin K epoxide reductase, preventing the recycling of vitamin K and thereby reducing the synthesis of clotting factors II, VII, IX, and X in the liver.
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 every 12 hours for 10-14 days; for uncomplicated UTI: 250 mg orally every 12 hours for 7 days.

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.
0.5-1 hour; prolonged in renal impairment (up to 20-30 hours in ESRD).
Renal: 70-90% unchanged by glomerular filtration and tubular secretion; biliary/fecal: <10%
Renal (80-90% unchanged via glomerular filtration and tubular secretion); biliary/fecal < 5%.
