What is aztreonam?

Aztreonam is an injectable antibiotic used to treat infections caused by susceptible bacteria. Aztreonam, which was originally sold under the brand name Azactam, is the first agent in a group of antibiotics called monobactam. Aztreonam kills only the bacteria called gram-negative. It will not kill Staphylococcal (staph) or Streptococcal (strep) bacteria because these are gram-positive. It is used to treat pneumonia, gynecological infections, urinary tract infections and infections of the skin, bone, joint, stomach and blood caused by susceptible gram-negative bacteria. It is administered intravenously and sometimes intramuscularly, usually two or three times a day.
