KLEBCIL vs PENBRITIN-S
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.
Penicillinase-sensitive penicillin; inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and activating autolytic enzymes.
KLEBCIL (ceftazidime-avibactam) 2.5 g (ceftazidime 2 g + avibactam 0.5 g) IV every 8 hours infused over 2 hours.
250-500 mg orally every 6 hours or 500 mg-1 g intramuscularly/intravenously every 4-6 hours for moderate to severe infections.

2-3 hours (prolonged to 30-60 hours in severe renal impairment; adjust dosing)
0.5-1 hour; prolonged in renal impairment (up to 7-10 hours in anuria).
Primarily renal (70-80% unchanged); minor biliary/fecal (15-20%)
Renal: 75-90% unchanged via glomerular filtration and tubular secretion; biliary/fecal: ~10%.
