AVYCAZ vs CEFEPIME AND DEXTROSE IN DUPLEX 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.
Cefepime is a fourth-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), particularly PBP 3, leading to cell lysis and death. It has activity against both gram-positive and gram-negative bacteria.
1 vial (ceftazidime 2g and avibactam 0.5g) IV over 2 hours every 8 hours.
1-2 g intravenously every 8-12 hours; typical dose 1 g IV q12h for most infections, 2 g IV q8h for severe infections.

Ceftazidime: ~2.8 hours; avibactam: ~2.7 hours. Extended in renal impairment (e.g., CrCl <50 mL/min requires dose adjustment).
Approximately 2 hours in adults with normal renal function; prolonged to 4–8 hours in mild-to-moderate renal impairment and up to 13–30 hours in severe impairment (CrCl <30 mL/min).
Ceftazidime: primarily renal (80-90% unchanged); avibactam: primarily renal (85-95% unchanged). Fecal excretion <1%.
Primarily renal (≥85% unchanged in urine via glomerular filtration and tubular secretion); biliary/fecal excretion minimal (<1%).
