Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefepime is a fourth-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby disrupting peptidoglycan cross-linking. It has enhanced activity against Gram-negative bacteria due to rapid penetration through the outer membrane and low affinity for β-lactamases.
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 every 8-12 hours for most indications; maximum 2 g every 8 hours for severe 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

Terminal elimination half-life is approximately 2-2.5 hours in adults with normal renal function; extends to 8-12 hours in moderate renal impairment (CrCl 30-60 mL/min) and up to 20-24 hours in severe impairment (CrCl < 30 mL/min).
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 (approximately 80-90% as unchanged drug) via glomerular filtration and tubular secretion; biliary/fecal excretion is minimal (< 1%).
Renal: 80-95% unchanged via glomerular filtration and tubular secretion; biliary: 5-10% excreted in feces; fecal: negligible.
