Aztreonam-avibactam is a drug combination pending phase 3 clinical trials and is suggested for treatment of severe infections caused by metallo-beta-lactamase (MBL)-producing by combining ceftazidime-avibactam and aztreonam. Beginning in 2019, four Antibiotic Resistance Laboratory Network regional laboratories offered aztreonam-avibactam susceptibility testing by broth microdilution. For 64 clinical isolates tested, the MIC and MIC values of aztreonam-avibactam were 0.5/4 μg/ml and 8/4 μg/ml, respectively. Aztreonam-avibactam displayed potent activity against the MBL-producing tested.
氨曲南-阿维巴坦是一种处于 3 期临床试验阶段的药物组合,建议用于治疗由产金属β-内酰胺酶(MBL)的 引起的严重感染,方法是将头孢他啶-阿维巴坦与氨曲南联合使用。自 2019 年以来,四个抗生素耐药性实验室网络区域实验室通过肉汤微量稀释法提供氨曲南-阿维巴坦药敏试验。对 64 株临床分离株进行检测,结果显示氨曲南-阿维巴坦的 MIC 和 MIC 值分别为 0.5/4μg/ml 和 8/4μg/ml。氨曲南-阿维巴坦对检测到的产 MBL 的 具有强大的 活性。
