Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bactericidal antibiotic that inhibits cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically inhibiting transpeptidase activity, 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.
250 mg orally every 6 hours for adults with normal renal function.
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

1.2-1.5 hours in normal renal function; prolonged in renal impairment (up to 10-20 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 by glomerular filtration and tubular secretion); remainder biliary/fecal (<10%)
Renal: 80-95% unchanged via glomerular filtration and tubular secretion; biliary: 5-10% excreted in feces; fecal: negligible.
