AZLIN vs KLEBCIL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Azlin is a penicillin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis.
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.
1-2 grams intravenously every 4-6 hours; total daily dose up to 12 grams for serious infections.
KLEBCIL (ceftazidime-avibactam) 2.5 g (ceftazidime 2 g + avibactam 0.5 g) IV every 8 hours infused over 2 hours.

Terminal elimination half-life is approximately 1.0–1.5 hours in adults with normal renal function; prolonged to 3–5 hours in moderate renal impairment (CrCl 10–50 mL/min) and up to 10 hours in severe renal impairment (CrCl <10 mL/min).
2-3 hours (prolonged to 30-60 hours in severe renal impairment; adjust dosing)
Renal excretion of unchanged drug (approximately 60-70% via glomerular filtration and tubular secretion); biliary/fecal excretion accounts for <10%.
Primarily renal (70-80% unchanged); minor biliary/fecal (15-20%)
