Optical Activity UNSPECIFIED

Avibactam (formerly NXL104, AVE1330A) is a synthetic non-β-lactam, covalent, slowly reversible β-lactamase inhibitor that inhibits the activities of Ambler class A and C β-lactamases and some Ambler class D enzymes. The combination of ceftazidime with avibactam exhibited broad-spectrum activity against Ambler class A- and class C-producing Enterobacteriaceae. AVYCAZ is a combination of ceftazidime, a cephalosporin, and avibactam indicated for the treatment of patients with the following infections caused by designated susceptible microorganisms: Complicated Intra-abdominal Infections, used in combination with metronidazole and Complicated Urinary Tract Infections, including Pyelonephritis.

Sample Use Guides

AVYCAZ 2.5 grams (ceftazidime 2 grams and avibactam 0.5 grams) for injection administered every 8 hours by intravenous (IV) infusion over 2 hours in patients 18 years of age and older with creatinine clearance (CrCl) greater than 50 mL/min. For treatment of Complicated Intra-abdominal Infections (cIAI), metronidazole should be given concurrently. Recommended duration of treatment: cIAI: 5 to 14 days, Complicated Urinary Tract Infections (cUTI) including pyelonephritis: 7 to 14 days.
Route of Administration: Intravenous
MICs of ceftazidime/AVE1330A(avibactam) for Enterobacteriaceae were at least eight-fold lower than those of ceftazidime alone. All of the Escherichia coli, Klebsiella pneumoniae, Citrobacter and Proteus mirabilis strains, including ceftazidime-resistant isolates, were inhibited at 4-8 mg/L. Only 2 mg/L were required to inhibit other Proteeae, Enterobacter, Salmonella and Serratia.
