奥硝唑(ornidazole,ONZ)是第三代硝基咪唑类抗生素，该类抗生素只针对厌氧菌感染，以及原虫、滴虫感染等。其作用机制是，使通过分子的硝基在无氧环境中还原成氨基，或通过自由基的形成，使受体螺旋组织结构断裂，阻断其转录复制而衰亡。过去这类感染一直使用甲硝唑、替硝唑防治。奥硝唑引入临床后，研究人员发现，与替硝唑、甲硝唑等硝基咪唑类药物相比，该品抗感染优势更为明显。这是因为，奥硝唑药效持续时间长，其血浆消除半衰期为14.4小时，高于甲硝唑的8.4小时和替硝唑的12.7小时，可减少患者服药次数，方便使用；致突变和致畸作用低于甲硝唑与替硝唑；在抗厌氧菌感染方面，奥硝唑的最低抑菌浓度和最低杀菌浓度均小于甲硝唑和替硝唑，疗效优于甲硝唑和替硝唑；局部用药疗效好于甲硝唑和替硝唑。
奥硝唑最早由美国Hoffer.M等研制成功,于1969年5月25日获美国专利。随后Hoffer.M等将其转让给Hoffmann-LaRocheandCo(瑞士)公司，Roche公司于1977年~1983年先后在德国、法国、意大利、瑞士、澳大利亚、瑞典等国以商品名“Tiberal”上市，剂型有片剂、胶囊剂和注射液。奥硝唑在细菌性阴道病治疗中作用明显，是治疗细菌性阴道病最有效的药物。此外，该品还可治疗子宫内膜炎、子宫肌炎、输卵管或卵巢脓肿、盆腔软组织感染等。
