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.
Cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking.
250-500 mg orally every 6 hours; maximum 4 g/day.
1 g intramuscularly or intravenously every 24 hours; for severe infections, 2 g every 24 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: 4-5 hours (prolonged to 12-24 hours in severe renal impairment; dosing adjustment recommended for CrCl <50 mL/min).
Primarily renal (90% or more unchanged via glomerular filtration and tubular secretion); small amounts biliary/fecal (<5%).
Renal: ~90% unchanged in urine via glomerular filtration and tubular secretion; biliary/fecal: ~5% (cefonicid undergoes minimal hepatic metabolism; ~4% excreted in feces as parent drug and metabolites).
