Abstract

Aztreonam is a monocyclic beta-lactam antibiotic that is active exclusively against the aerobic gram-negative bacilli. It is not ototoxic or nephrotoxic and so is used as an alternative to aminoglycosides in a variety of clinical situations. In polymicrobial infections or when used for empiric therapy, aztreonam must be combined with other antimicrobial agents active against gram-positive and anaerobic species. Aztreonam is often effective against resistant strains of gram-negative organisms, which are often involved in nosocomial infections. Overuse of aztreonam should be avoided to prevent the emergence of resistant P. aeruginosa strains. Except in the treatment of P. aeruginosa infections, aztreonam should not be added to beta-lactam regimens for additional gram-negative coverage.
