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.
Cefotaxime is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), blocking transpeptidation, and activating autolytic enzymes.
1 vial (ceftazidime 2g and avibactam 0.5g) IV over 2 hours every 8 hours.
1-2 g IV/IM every 8-12 hours; maximum 12 g/day for severe 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 is approximately 0.6-1.2 hours in adults with normal renal function. In neonates, it is prolonged (2-6 hours). In renal impairment, half-life extends significantly (up to 15-30 hours in anuria), requiring dose adjustment.
Ceftazidime: primarily renal (80-90% unchanged); avibactam: primarily renal (85-95% unchanged). Fecal excretion <1%.
Primarily renal: approximately 60-80% of the dose is excreted unchanged in urine via glomerular filtration and tubular secretion. Small amounts are eliminated in bile (<10%) and feces (<1%).
