米索前列醇的临床应用

米索前列醇（misoprostol,米索）是人工合成的前列腺素E_1的衍生物,有多方面临床用途。80年代早期米索最先开始用于治疗消化性溃疡,尤其是对非甾体类抗炎药引起的胃十二指肠溃疡有明显疗效,对急性应激性溃疡也有预防作用。米索可引起腹泻,但因此也可治疗严重便秘的患者。随后发现米索对肝、肾有保护作用,还具明显抗炎、抗过敏作用;与其它抗早孕药合用,米索可使完全流产率大大提高;对人工流产术前的病人用米索可软化并扩张宫颈,从而减轻扩宫时病人的痛苦,使手术顺利进行。对米索的毒副作用研究发现其毒性主要表现在消化系统和雄性生殖系统,但一般比较轻微,无明显其它不良反应。故米索可谓一种高效、低毒的药物,值得临床推广。但男性患者在长期大量应用该药时需注意其对生殖系统的影响,孕妇应禁用。
