ANSPOR vs CEFIZOX
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.
Cefizox (ceftizoxime) is a third-generation cephalosporin that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting transpeptidation and autolysin inhibition.
250-500 mg orally every 6 hours for 10-14 days; maximum 4 g/day.
1-2 g IV/IM every 8-12 hours; maximum 12 g/day for severe infections.
