AVYCAZ vs CEFUROXIME SODIUM 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 beta-lactam cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death. It has bactericidal activity against susceptible organisms.
1 vial (ceftazidime 2g and avibactam 0.5g) IV over 2 hours every 8 hours.
1.5 g IV every 8 hours for moderate to severe infections; may be increased to 3 g IV every 8 hours for severe or life-threatening infections.

Ceftazidime: ~2.8 hours; avibactam: ~2.7 hours. Extended in renal impairment (e.g., CrCl <50 mL/min requires dose adjustment).
Terminal elimination half-life: 1.2-1.9 hours. Prolonged in renal impairment (up to 15-20 hours with CrCl <20 mL/min).
Ceftazidime: primarily renal (80-90% unchanged); avibactam: primarily renal (85-95% unchanged). Fecal excretion <1%.
Renal excretion: 80-90% unchanged by glomerular filtration and tubular secretion. Biliary/fecal: <10%.
