CEFTIN vs CEPHALEXIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ceftin (cefuroxime axetil) is a second-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically transpeptidases, thereby disrupting peptidoglycan cross-linking. This leads to cell lysis and death primarily during active cell division.
Cephalexin is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting transpeptidation and disrupting cell wall cross-linking, leading to cell lysis and death.
250-500 mg orally twice daily for 10 days; for community-acquired pneumonia, 500 mg twice daily for 10 days. Intravenous: 750-1500 mg every 8 hours.
Oral: 250-1000 mg every 6 hours; maximum 4 g/day.
