Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and autolysin activation, leading to cell lysis.
Cephalexin binds to penicillin-binding proteins (PBPs) on the bacterial cell wall, inhibiting transpeptidation and disrupting peptidoglycan cross-linking, leading to cell lysis via autolytic enzymes.
1-2 g IV/IM every 4-6 hours; maximum 12 g/day.
Cefuroxime axetil (KEFTAB) 250-500 mg orally twice daily for 7-10 days. For uncomplicated urinary tract infections: 250 mg twice daily; for acute otitis media: 500 mg twice daily.

Terminal elimination half-life: 0.5-1 hour (normal renal function); prolonged to 2-3 hours in anuria. Clinically, dosing every 6 hours is recommended.
0.8-1.2 hours (prolonged to 6-8 hours in renal impairment; requires dose adjustment for CrCl <50 mL/min)
Renal: 70-80% unchanged via glomerular filtration and tubular secretion; biliary: minimal (<5%); fecal: <1%.
Renal: 90-95% unchanged via glomerular filtration and tubular secretion; biliary/fecal: <5%
