ZAVICEFTA is a combination antibiotic medication used to treat a variety of bacterial infections, particularly those that are difficult to treat due to resistance to other antibiotics. It contains two active ingredients: ceftazidime, which is a third-generation cephalosporin antibiotic, and avibactam, a non-β-lactam β-lactamase inhibitor. This combination enhances the activity of ceftazidime against a broad spectrum of gram-positive and gram-negative bacteria, including those that produce certain types of enzymes (β-lactamases) that can inactivate many other antibiotics. ZAVICEFTA is administered intravenously and is commonly used in hospital settings for the treatment of complex infections such as complicated urinary tract infections, complicated intra-abdominal infections, and hospital-acquired pneumonia, including ventilator-associated pneumonia. Its role in combating antibiotic-resistant infections makes it a critical tool in modern medicine.
