Avycef IV Infusion is indicated in- Complicated Intra-abdominal Infections (cIAI) Complicated Urinary Tract Infections (cUTI), including Pyelonephritis Hospital-acquired Bacterial Pneumonia and Ventilator-associated Bacterial Pneumonia (HABP/VABP)
Ceftazidime inhibits bacterial peptidoglycan cell wall synthesis following binding to penicillin binding proteins (PBPs), which leads to bacterial cell lysis and death. Avibactam is a non β-lactam, β-lactamase inhibitor that acts by forming a covalent adduct with the enzyme that is stable to hydrolysis. It inhibits both Ambler class A and class C β-lactamases and some class D enzymes, including extended-spectrum β-lactamases (ESBLs), KPC and OXA-48 carbapenemases, and AmpC enzymes. Avibactam does not inhibit class B enzymes (metallo-β-lactamases) and is not able to inhibit many class D enzymes.

Adult cIAI, cUTI and HABP/VABP Patients: The most common adverse reactions in cIAI (≥ 5%, when used with metronidazole) patients are diarrhea, nausea and vomiting. The most common adverse reactions (3%) in cUTI patients are diarrhea and nausea. The most common adverse reactions (≥5%) in HABP/VABP patients were diarrhea and vomiting. Pediatric cIAI and cUTI Patients: The most common adverse reactions (>3%) in pediatric patients were vomiting, diarrhea, rash, and infusion site phlebitis
This is contraindicated in patients with known serious hypersensitivity to the components of (ceftazidime and avibactam), avibactam-containing products or other members of the cephalosporin class.
Clinical interaction study of this IV infusion or avibactam alone with probenecid has not been conducted, co-administration of this IV infusion with probenecid is not recommended.
Decreased efficacy in adult cIAI patients with baseline CrCl of 30 to less than or equal to 50 mL/ min: Monitor CrCl at least daily in adult and pediatric patients with changing renal function and adjust the dose of this IV infusion accordingly. Hypersensitivity reactions: Includes anaphylaxis and serious skin reactions. Cross-hypersensitivity may occur in patients with a history of penicillin allergy. If an allergic reaction occurs, discontinue this IV infusion. Clostridium difficile-associated diarrhea (CDAD): CDAD has been reported with nearly all systemic antibacterial agents, including this IV infusion. Evaluate if diarrhea occurs. Central Nervous System Reactions: Seizures and other neurologic events may occur, especially in patients with renal impairment. Adjust dose in patients with renal impairment.
