AVYCAZ vs MANDOL
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.
Cephalosporin antibiotic; inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking.
1 vial (ceftazidime 2g and avibactam 0.5g) IV over 2 hours every 8 hours.
1-2 g IV or IM every 4-8 hours; maximum 12 g/day.

Clinical Note
moderateCefamandole + Probenecid
"The serum concentration of Probenecid can be increased when it is combined with Cefamandole."
Clinical Note
moderateCefamandole + Picosulfuric acid
"The therapeutic efficacy of Picosulfuric acid can be decreased when used in combination with Cefamandole."
Clinical Note
moderateWarfarin + Cefamandole
"Warfarin may increase the anticoagulant activities of Cefamandole."
Clinical Note
moderatePhenprocoumon + Cefamandole
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 1.2-1.8 hours in adults with normal renal function; prolonged to 4-8 hours in moderate renal impairment (CrCl 30-50 mL/min) and >12 hours in severe impairment (CrCl <30 mL/min).
Ceftazidime: primarily renal (80-90% unchanged); avibactam: primarily renal (85-95% unchanged). Fecal excretion <1%.
Renal: 65-85% unchanged via glomerular filtration and tubular secretion; biliary/fecal: ~15-20% as active drug and metabolites; minor hepatic metabolism.
