AVYCAZ vs KEFUROX IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
AVYCAZ is a combination of ceftazidime, a cephalosporin beta-lactam antibiotic, and avibactam, a non-beta-lactam beta-lactamase inhibitor. Ceftazidime inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis. Avibactam protects ceftazidime from degradation by certain beta-lactamases, including Ambler class A, class C, and some class D enzymes.
Cefuroxime is a second-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically PBP-3 and PBP-1a/1b, leading to inhibition of transpeptidase activity and autolysin-mediated cell death.
1 vial (ceftazidime 2g and avibactam 0.5g) IV over 2 hours every 8 hours.
750 mg to 1.5 g IV every 8 hours; for severe infections, up to 3 g IV every 8 hours.

Ceftazidime: ~2.8 hours; avibactam: ~2.7 hours. Extended in renal impairment (e.g., CrCl <50 mL/min requires dose adjustment).
1.2-1.6 hours in adults with normal renal function. Extended to 15-22 hours in end-stage renal disease.
Ceftazidime: primarily renal (80-90% unchanged); avibactam: primarily renal (85-95% unchanged). Fecal excretion <1%.
Renal: 80-90% unchanged by glomerular filtration and tubular secretion. Biliary: <2% excreted in bile. Fecal: <1%.
