Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefixime is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting peptidoglycan cross-linking. It has broad-spectrum activity against gram-positive and gram-negative bacteria.
Cefuroxime, a second-generation cephalosporin, inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking.
400 mg orally once daily or 200 mg orally every 12 hours.

Terminal elimination half-life: 3-4 hours in normal renal function; prolonged to 11-15 hours in severe renal impairment (CrCl <20 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.
Renal: 50-55% unchanged in urine; biliary/fecal: 10-20% (biliary excretion); remainder metabolized or excreted via feces.
Renal: 80-95% unchanged via glomerular filtration and tubular secretion; biliary: 5-10% excreted in feces; fecal: negligible.
