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), leading to cell lysis and death. It has broad-spectrum activity against gram-positive and gram-negative bacteria.
1 vial (ceftazidime 2g and avibactam 0.5g) IV over 2 hours every 8 hours.
1-2 g IV every 4-6 hours; maximum 12 g/day.

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: 0.8-1.4 hours in adults with normal renal function; prolonged to 2.5-15 hours in renal impairment; clinical context: dosing interval adjustment required for CrCl <20 mL/min
Ceftazidime: primarily renal (80-90% unchanged); avibactam: primarily renal (85-95% unchanged). Fecal excretion <1%.
Primarily renal (80-90% unchanged within 24 hours); biliary/fecal elimination accounts for <10%
