{{/items}} {{^items}}Description
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.
Indication
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.
Mechanism of Action
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.
Clearance
Avibactam and ceftazidime has a clearance of ~12L/h and ~7L/h respectively.
Toxicity
Avycaz is contraindicated in patients with known serious hypersensitivity to avibactam-containing products, ceftazidime or other members of the cephalosporin class.

Description
Semisynthetic, broad-spectrum antibacterial derived from cephaloridine and used especially for Pseudomonas and other gram-negative infections in debilitated patients.
Indication
For the treatment of patients with infections caused by susceptible strains of organisms in the following diseases: lower respiratory tract infections,skin and skin structure infections, urinary tract infections, bacterial septicemia, bone and joint infections, gynecologic infections, intra abdominal infections (including peritonitis), and central nervous system infections (including meningitis).
Mechanism of Action
The bactericidal activity of ceftazidime results from the inhibition of cell wall synthesis via affinity for penicillin-binding proteins (PBPs).
Pharmacokinetics
- Absorption
- The absorption of ceftazidime is directly proportional to the size of the dose.
- Distribution
- Metabolism
- Elimination
Clearance
* 115 mL/min
Toxicity
Ceftazidime overdosage has occurred in patients with renal failure. Reactions have included seizure activity, encephalopathy, asterixis, neuromuscular excitability, and coma.
