Avibactam
Avibactam Uses, Dosage, Side Effects, Food Interaction and all others data.
Avibactam is a non-β-lactam β-lactamase inhibitor that is available in combination with ceftazidime (Avycaz). This combination was approved by the FDA on February 25, 2015 for the treatment of complicated intra-abdominal infections in combination with metronidazole, and the treatment of complicated urinary tract infections, including pyelonephritis caused by antibiotic resistant-pathogens, including those caused by multi-drug resistant gram-negative bacterial pathogens. As there is limited clinical safety and efficacy data, Avycaz should be reserved for patients over 18 years old who have limited or not alternative treatment options.

Uses
Avibactam is a non-β-lactam β-lactamase inhibitor used in combination with ceftazidime for the treatment of complicated intra-abdominal infections, complicated urinary tract infections, and hospital or ventilator-acquired pneumonia.
AVYCAZ (ceftazidime-avibactam), in combination with metronidazole, is indicated for the treatment of complicated intra-abdominal infections caused by the following susceptible microorganisms: Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Providencia stuartii, Enterobacter cloacae, Klebsiella oxytoca, and Pseudomonas aeruginosa in patients 18 years or older. AVYCAZ is also indicated for the treatment of complicated urinary tract infections including pyelonephritis caused by the following susceptible microorganisms: Escherichia coli, Klebsiella pneumoniae, Citrobacter koseri, Enterobacter aerogenes, Enterobacter cloacae, Citrobacter freundii, Proteus spp., and Pseudomonas aeruginosa in patients 18 years or older.
Avibactam is also used to associated treatment for these conditions: Bacterial Infections, Complicated Intra-Abdominal Infections, Complicated Urinary Tract Infection, Complicated Pyelonephritis
How Avibactam works
Avibactam is a non-β lactam β-lactamase inhibitor that inactivates some β-lactamases (Ambler class A β-lactamases, including Klebsiella pneumoniae carbapenemases, Ambler class C and some Ambler class D β-lactamases) by a unique covalent and reversible mechanism, and protects ceftazidime from degradation by certain β-lactamases. Avibactam rapidly reaches the periplasm of bacteria at high enough concentrations to restore activity of ceftazidime against ceftazidime-resistant, β-lactamase-producing strains. Avibactam does not decrease the activity of ceftazidime against ceftazidime susceptible organisms.
Toxicity
Avycaz is contraindicated in patients with known serious hypersensitivity to avibactam-containing products, ceftazidime or other members of the cephalosporin class.
