Indications
Treatment of severe infections caused by extensively resistant/Carbapenem-Resistant Enterobacterales (CRE) confirmed or suspected metallo-beta-lactamase producer (in combination with ceftazidime/avibactam), and non-severe infections when treatment options are limited.
Treatment of infections caused by Stenotrophomonas maltophilia (second-line for non-CNS infections, third-line for CNS infections).
Third-line treatment of infections caused by Stenotrophomonas maltophilia, in combination with ceftazidime/avibactam.
