CEPHAPIRIN SODIUM vs KEFTAB
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cephapirin sodium is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), primarily PBP1 and PBP3, thereby inhibiting transpeptidation and disrupting peptidoglycan cross-linking, leading to cell lysis mediated by autolytic enzymes.
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.
500 mg to 1 g IM or IV every 6 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.
