AZTREONAM

Infectious Disease Approved 2010-06-18

Aztreonam is a monobactam antibacterial used to manage various infections caused by susceptible Gram-negative bacteria. It helps patients with conditions ranging from urinary tract and respiratory infections to more severe cases like septicemia and intra-abdominal infections. Clinicians typically prescribe this medication when culture results or local epidemiology suggest that these specific bacteria are responsible for the illness.

How AZTREONAM Works

Aztreonam works by inhibiting the synthesis of bacterial cell walls, which leads to the death of the bacteria. As a bactericidal agent, it maintains its activity even in the presence of certain enzymes, such as penicillinases and cephalosporinases, that often break down other antibiotics.
