Which of the following cephalosporins is also known as Zerbaxa?

Zerbaxa is the brand name for the combination of ceftazidime and avibactam. In this context, although avibactam is important for extending the spectrum of ceftazidime against certain resistant bacteria, the question specifically aims for the cephalosporin component that’s commonly associated with the Zerbaxa name.

Ceftazidime is recognized for its effectiveness against gram-negative bacteria, particularly in treating severe infections caused by organisms such as Pseudomonas aeruginosa. The addition of avibactam in Zerbaxa enhances its ability to combat beta-lactamase producing organisms that would otherwise be resistant to ceftazidime alone.

Cefiderocol is a unique cephalosporin that has a different mechanism of action through iron-mediated transport and is not associated with Zerbaxa. Cefepime, another broad-spectrum cephalosporin, does not include avibactam in its formulation and is also not linked to the Zerbaxa name. CEFNAP, which might refer to an experimental or lesser-known cephalosporin, does not relate to Zerbaxa.

Thus, the recognition that Zerbaxa specifically involves ceftazid
