KLEBCIL vs PENTIDS '400'
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 binds to penicillin-binding proteins (PBPs) located on the bacterial cell wall, inhibiting transpeptidase activity and disrupting 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.
400 mg orally every 6 hours.

2-3 hours (prolonged to 30-60 hours in severe renal impairment; adjust dosing)
0.5-1 hour in patients with normal renal function. Prolonged to 2-5 hours in renal impairment, requiring dose adjustment.
Primarily renal (70-80% unchanged); minor biliary/fecal (15-20%)
Primarily renal (tubular secretion and glomerular filtration); 60-90% of dose excreted unchanged in urine within 24 hours. Minor biliary excretion (<10%) and fecal elimination.
