甲硝唑常用于治疗厌氧菌感染,因厌氧菌感染大多为混合感染,临床上多将其与抗需氧菌抗生素红霉素联用。二者配伍是否影响红霉素抗菌活性,目前尚未见报道。由此笔者对红霉素在甲硝唑注射液中的稳定性进行了研究。在实验过程中,意外发现甲硝唑对短小芽胞杆 Metronidazole commonly used in the treatment of anaerobic infections, mostly due to mixed infection of anaerobic bacteria, clinically more with anti-aerobic antibiotic erythromycin combined. The compatibility of the two affect the antibacterial activity of erythromycin, has not been reported. Therefore, the author of erythromycin in metronidazole injection stability studies. During the experiment, metronidazole was found accidentally on the spores of short shoots
