ABSTRACT Objective: To establish a method for the determination of the microbial limit test of tinidazole suppositories according to ChP 2015 Volume IV. Methods: Three parallel tests were carried out by applying an improved sample preparation method and membrane-filtering procedure. Results: The recovery rates of five microorganisms including Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus subtilis, Candida albicans and Aspergillus niger were more than 50% and less than 200% by plate counting. Every positive test microorganism could be detected while negative control one could not grow in the examination of control microorganisms. Conclusion: This method for the microbial limit tests of tinidazole suppositories is feasible.
KEY WORDS ChP 2015; tinidazole suppositories; the suitability of the method
替硝唑栓具有抗原生动物和专性厌氧细菌的作用,适用于治疗滴虫性阴道炎及敏感厌氧菌所引起的细菌性阴道病,是妇科常用药物。该品与同类产品甲硝唑栓相比,其临床适应证相同,但疗效优于甲硝唑栓,不良反应明显少于甲硝唑栓,所以特别适用于经甲硝唑栓治疗疗效不明显或因不良反应难以接受甲硝唑栓治疗的患者。为有效控制药品质量,保证微生物限度检查方法的科学性和检验结果的准确性,根据2015年版《中国药典》四部微生物限度检查的新要求[1],对替硝唑栓进行了微生物限度检查的方法适用性试验研究[2]。
