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; 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.
250-500 mg orally every 6 hours or 1-2 g intramuscularly/intravenously every 6-12 hours for moderate to severe infections.
