Résumé
Cefoxitin can induce chromosomal beta-lactamases in some Gram-negative bacteria such as Enterobacter and Pseudomonas, which may reduce aztreonam activity. This is an in vitro antagonism, and its clinical relevance is uncertain.
Ce que signifie cette interaction, en termes simples
Aztreonam and Cefoxitin can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Aztreonam belongs to Anti Bacterial; Cefoxitin belongs to Anti Bacterial.
Pourquoi elle survient
Cefoxitin induces inducible beta-lactamase production in some Gram-negative bacteria, which can hydrolyze aztreonam.
Conduite à tenir
Avoid pairing the two when treating organisms known to produce inducible beta-lactamases. Guide therapy by culture and susceptibility results.
