Treatment of choice

Use for

Adding avibactam to ceftazidime increases activity against carbapenem-resistant pathogens with OXA-48, KPC, AmpC (including derepressed hyperproducing Enterobacter17), and andhas similar spectrum/coverage against ESBLs as carbapenems.


Don't use for

Metallo-beta-lactamases are not inhibited by avibactam. Useful against the KPC.

Treating carbapenam resistant E. coli and K. pneumoniae has a high failure rate (PubMed).
