Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cephalexin is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
Cefuroxime is a second-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby blocking transpeptidation and leading to cell lysis and death.
250-500 mg orally every 6 hours; maximum 4 g/day.
750 mg intravenously or intramuscularly every 8 hours; for severe infections, 1.5 g intravenously every 8 hours.

0.5–1.2 hours in patients with normal renal function (CrCl >50 mL/min); prolonged to >20 hours in ESRD.
Terminal elimination half-life is approximately 1.5 hours in adults with normal renal function; prolonged to 3-4 hours in neonates and up to 20-30 hours in end-stage renal disease.
Primarily renal (90% or more unchanged via glomerular filtration and tubular secretion); small amounts biliary/fecal (<5%).
Approximately 80-90% of the dose is excreted unchanged in the urine via glomerular filtration and tubular secretion; the remainder is eliminated via bile and feces.
