Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting peptidoglycan cross-linking, leading to cell lysis.
Cefuroxime, a second-generation cephalosporin, inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking.
1-2 g IV/IM every 8-12 hours; maximum 6 g/day for serious infections.
750 mg IV/IM every 8 hours; for severe infections: 1.5 g IV every 8 hours; for life-threatening infections: 1.5 g IV every 6 hours

2 hours (normal renal function); prolonged to 12-20 hours in ESRD
Terminal elimination half-life: 1.5-2 hours in adults with normal renal function; prolonged to 2.5-3.5 hours in elderly and up to 48 hours in end-stage renal disease.
Primarily renal (80-90% unchanged) via glomerular filtration and tubular secretion; 5-10% biliary/fecal
Renal: 80-95% unchanged via glomerular filtration and tubular secretion; biliary: 5-10% excreted in feces; fecal: negligible.
