甲硝唑海绵栓和普通灭滴灵栓对体外阴道毛滴虫杀伤实验表明，两种剂型的甲硝唑对滴虫均有明显杀伤作用，且随药物浓度加大，作用时间延长，虫体死亡率增高。但是，同一药物浓度、同一作用时间，甲硝唑海绵栓组虫体死亡率明显高于灭滴灵栓组。 Metronidazole sponge suppository and ordinary metronidazole on the vaginal Trichomonas vaginalis killing experiments showed that the two formulations of metronidazole on the trichomoniasis have significant killing effect, and with the drug concentration increases, the role of time, the body Mortality increased. However, the same drug concentration, the same action time, metronidazole sponge embolism group worm mortality was significantly higher than metronidazole group.
