KLEBCIL vs OXACILLIN SODIUM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Oxacillin is a penicillinase-resistant beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby blocking the transpeptidation step in peptidoglycan cross-linking. It is resistant to staphylococcal beta-lactamase.
KLEBCIL (ceftazidime-avibactam) 2.5 g (ceftazidime 2 g + avibactam 0.5 g) IV every 8 hours infused over 2 hours.
1-2 grams IV every 4-6 hours.

2-3 hours (prolonged to 30-60 hours in severe renal impairment; adjust dosing)
0.3-0.8 hours in adults with normal renal function; prolonged to 1-2 hours in neonates and 2-5 hours in patients with severe renal impairment (CrCl <10 mL/min)
Primarily renal (70-80% unchanged); minor biliary/fecal (15-20%)
Renal (70-80% unchanged by tubular secretion and glomerular filtration); biliary (minor, approximately 10%)
