CEFTRIAXONE SODIUM vs CEFUROXIME AXETIL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ceftriaxone inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and disrupting peptidoglycan cross-linking.
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 12-24 hours; maximum 4 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.

Terminal elimination half-life is 5.8-8.7 hours in adults with normal renal and hepatic function. In neonates, half-life is prolonged (up to 16 hours). In patients with renal impairment, half-life increases to 12-18 hours; in hepatic impairment, it may be 15-20 hours. Dose adjustment is not typically required unless both renal and hepatic impairment are present.
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.
Ceftriaxone is eliminated 33-67% unchanged in urine via glomerular filtration and tubular secretion, and the remainder is excreted in feces (primarily as microbiologically inactive metabolites) via biliary secretion. Biliary excretion accounts for approximately 35-45% of total clearance.
Renal: 70-90% unchanged by glomerular filtration and tubular secretion; biliary/fecal: <10%
