米索前列醇(Misoprostol),常见商品名为Cytotec,是一种人工合成的PGE1药物[1]。用于加速分娩流产、预防或治疗胃溃疡,或治疗因为子宫收缩不足所造成的产后出血[1]。 如果用于流产,常常会搭配美服培酮(mifepristone)或是氨甲蝶呤(methotrexate)使用[2]。 单独使用米索前列醇的成功率介于66%到90%之间[3]。 可置于双颊、下或是以阴道塞剂的方式给予[2][4]

常见的副作用包括腹痛腹泻[1]妊娠期间用药会对胎儿带来负面影响,怀孕分级为X级[1] 。使用此药物,会造成子宫收缩,偶见甚至造成子宫破裂英语uterine rupture[1]

米索前列醇于1973年开发完成[5]。米索前列醇是世界卫生组织基本药物标准清单的其中之一,意即在基本医疗卫生制度里非常需要、也相当重要的一项药物[6]。 目前已有学名药上市[1]。在发展中国家,每剂药物批发价介于0.36美金到2美金[7]。 在美国使用米索前列醇用于治疗胃溃疡,每个月需要花费100到200美金[8]
