KLEBCIL vs PENTIDS '800'
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.
Penicillin G is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), transpeptidases that catalyze the final transpeptidation step of peptidoglycan cross-linking, leading to cell lysis.
KLEBCIL (ceftazidime-avibactam) 2.5 g (ceftazidime 2 g + avibactam 0.5 g) IV every 8 hours infused over 2 hours.
800 mg orally every 6 to 8 hours; maximum 4 g per day.

2-3 hours (prolonged to 30-60 hours in severe renal impairment; adjust dosing)
0.5-1 hour; prolonged to 2-5 hours in renal impairment.
Primarily renal (70-80% unchanged); minor biliary/fecal (15-20%)
Renal: ~60-85% unchanged via glomerular filtration and tubular secretion; Biliary: ~10%; Fecal: <5%.
