aztreonam is an approved drug (FDA (1986), EMA (2009))
Compound class: Synthetic organic
Comment: Aztreonam is a monocyclic β-lactam antibiotic that is resistant to β-lactamase hydrolysis. It was isolated from Chromobacterium violaceum. Functionally it preferentially binds to and inactivates penicillin-binding protein-3 (PBP-3) and thereby inhibits bacterial cell wall synthesis. Aztreonam was removed from the World Health Organization's List of Essential Medicines in 2019.

Summary of Clinical Use Click here for help
Aztreonam is used as a single agent to treat serious infevtions that are caused by susceptible gram-negative bacteria e.g. Citrobacter (including C. freundii), Enterobacter (including E. cloacae), E. coli, Klebsiella (including K. pneumoniae), Pseudomonas aeruginosa, or Serratia (including S. marcescens). In the EU, aztreonam (Cayston®) is indicated for the suppressive therapy of chronic pulmonary Pseudomonas aeruginosa infections in cystic fibrosis patients.Aztreonam is being investigated in an intravenous fixed-dose combination with the β-lactamase inhibitor avibactam (ATM-AVI; PF-06947387) for the treatment of serious bacterial infections.
