CLOXACILLIN SODIUM vs KLEBCIL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cloxacillin is a beta-lactam antibiotic that binds to penicillin-binding proteins (PBPs) located on the bacterial cell wall, inhibiting transpeptidases and thus preventing the cross-linking of peptidoglycan chains. This leads to cell lysis and death, primarily mediated by autolytic enzymes. It is resistant to penicillinase (beta-lactamase) produced by staphylococci.
Klebcillin is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and activating autolytic enzymes.
250-500 mg orally every 6 hours on an empty stomach; 250 mg - 2 g IV/IM every 4-6 hours depending on severity; maximum 12 g/day for serious infections.
KLEBCIL (ceftazidime-avibactam) 2.5 g (ceftazidime 2 g + avibactam 0.5 g) IV every 8 hours infused over 2 hours.
