CECLOR CD vs KEFTAB
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefaclor, a second-generation cephalosporin, inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby disrupting peptidoglycan cross-linking.
Cephalexin binds to penicillin-binding proteins (PBPs) on the bacterial cell wall, inhibiting transpeptidation and disrupting peptidoglycan cross-linking, leading to cell lysis via autolytic enzymes.
250-500 mg orally every 8 hours; extended-release form (CECLOR CD) 375-750 mg orally every 12 hours.
Cefuroxime axetil (KEFTAB) 250-500 mg orally twice daily for 7-10 days. For uncomplicated urinary tract infections: 250 mg twice daily; for acute otitis media: 500 mg twice daily.
