Avibactam (AVI)

Pfizer · FDA-approved active Small molecule

Avibactam is a beta-lactamase inhibitor that protects beta-lactam antibiotics from enzymatic degradation by binding to and inactivating bacterial beta-lactamases.

Avibactam is a beta-lactamase inhibitor that protects beta-lactam antibiotics from enzymatic degradation by binding to and inactivating bacterial beta-lactamases. Used for Complicated urinary tract infections (cUTI) in combination with ceftazidime, Hospital-acquired bacterial pneumonia (HABP) and ventilator-associated bacterial pneumonia (VABP) in combination with ceftazidime, Complicated intra-abdominal infections (cIAI) in combination with ceftazidime.

Mechanism of action

Avibactam is a non-beta-lactam beta-lactamase inhibitor that works through a mechanism distinct from traditional inhibitors. It binds covalently to serine beta-lactamases and reversibly to metallo-beta-lactamases, preventing these enzymes from breaking down beta-lactam antibiotics. This allows beta-lactam drugs to remain active against otherwise resistant bacteria, restoring their therapeutic efficacy.
