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 inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting the final transpeptidation step of peptidoglycan synthesis, leading to cell lysis.
250-500 mg orally every 6 hours; maximum 4 g/day.
750 mg to 1.5 g intramuscularly or intravenously every 8 hours; for severe infections, 1.5 g intravenously every 6 to 8 hours.

0.5–1.2 hours in patients with normal renal function (CrCl >50 mL/min); prolonged to >20 hours in ESRD.
1.2-1.6 hours in adults with normal renal function (Clcr >80 mL/min); prolonged to 10-20 hours in end-stage renal disease (Clcr <10 mL/min).
Primarily renal (90% or more unchanged via glomerular filtration and tubular secretion); small amounts biliary/fecal (<5%).
