Oral mifepristone 600 mg and vaginal gemeprost for mid-trimester induction of abortion: An open multicenter study

This open multicenter study was performed in 20 hospital gynecological units in the UK. The effects of 600 mg oral mifepristone as pretreatment to vaginal prostaglandin induction of second second trimester abortion was studied in 267 women.

The primary efficacy variable was the abortion induction interval, defined as the time taken to expel the fetus from the time of administration of the first prostaglandin pessary. Induction was commenced 36 to 48 hours following mifepristone intake.

The mean abortion induction interval was 7 h. A total of 81.9% of women aborted within 12 h. There was a significant relationship between abortion induction interval and age of gestation, and a significant inverse relationship between abortion induction interval and parity.

Vomiting, pelvic pain, and nausea were the most frequently reported adverse events. Two patients required transfusion and one patient with a uterine scar from a previous cesarean section suffered a ruptured uterus and hysterotomy.     

Transplacental passage of mifepristone and its influence on maternal and fetal steroid concentrations in the second trimester of pregnancy

The maternal and fetal endocrine effects of the maternal administration of the anti-progestin mifepristone in mid-pregnancy have been investigated. Mifepristone and the metabolite RU 42,633 were detected in the fetal circulation and in the amniotic fluid 4, 24 and 48 h after oral ingestion. Maximum fetal plasma concentrations of mifepristone occurred 4 h after treatment indicating rapid placental transfer of the drug. No significant changes in progesterone, cortisol, oestradiol or aldosterone concentrations were detected in the maternal circulation after mifepristone treatment. No significant changes occurred in the fetal progesterone, oestradiol or cortisol concentrations, but a significant increase in fetal aldosterone occurred 4 and 24 h after treatment. The significance of these results is discussed in relation to the possible therapeutic uses of mifepristone for inducing labour.     

Update on medication abortion

This article provides an overview of medication abortion in the United States 6 years after the approval of mifepristone (RU486; Mifeprex; Danco Laboratories, LLC, New York, NY) by the US Food and Drug Administration (FDA). The adoption of mifepristone is considered in the context of epidemiologic data on abortion, abortion access, and the safety of abortion. The risks of medication and aspiration abortion are discussed in the context of abortion-related mortality, recent experience with obstetric and gynecologic infection with Clostridium sordellii, and the limits of scientific knowledge on the incidence of this infection in women. Innovative protocols studied since FDA approval of mifepristone are presented, and implications for clinical practice are discussed.     

小剂量米非司酮用于紧急避孕临床观察

目的 观察一次性小剂量米非司酮用于紧急避孕的效果。方法征集无保护性交或避孕失败后72小时内就诊并符合条件的健康妇女100例，单次口服米非司酮10mg。结果失败1例，按照Dixon方法计算，避孕有效率为89．55％；受试的月经周期无明显改变且未出现明显副作用。结论小剂量米非司酮单次口服用于紧急避孕简单、有效、安全。     

米非司酮配伍米索前列醇终止早孕用药方法的探讨

作者对１２０例妊娠４９ｄ以内的孕妇采用４种不同的服药方法进行药物流产，其中使用第３、４种用药方法的孕妇均于加用米索前列醇后８ｈ内排出孕囊，且２ｈ内排出率明显增加，与常规用药方法比较有显著性差异（Ｐ＜０．０１），同时对用药机理作了讨论。     

米非司酮配伍米索前列醇终止早孕118例临床观察

就米非司酮配伍采米前列醇序贯用药终止７周内早孕１１８例进行临床观察，发现完全流产率９２．３７％，不全流产率５．９３％，持续妊娠率１．６９％。临床证明该方法方便、安全有效、副作用极小，但个别孕妇产生不全流产，引起出血过多及出血时间延长。不全流产率有随孕妇年龄、孕龄、孕次增加而增加的趋势。     

A prospective randomized,double-blinded,placebo-controlled trial comparing mifepristone and vaginal misoprostol to vaginal misoprostol alone for elective termination of early pregnancy

BACKGROUND: Vaginal misoprostol has been shown to be an effective single agent for medical abortion. This randomized, double-blinded, placebo-controlled trial compared a regimen of mifepristone and misoprostol with misoprostol alone for termination of early pregnancy. METHODS: 250 women with gestations < or = 56 days were randomized by a random number table to receive either 200 mg mifepristone orally or placebo followed 48 h later by 800 microg vaginal misoprostol. Administration of misoprostol was repeated every 24 h up to three doses if abortion failed to occur. Abortion success was defined as complete abortion without the use of surgical aspiration. RESULTS: Successful medical abortions occurred in 114 out of 119 subjects (95.7%) after mifepristone followed by vaginal misoprostol. In all, 110 out of 125 subjects (88.0%) successfully aborted after placebo and vaginal misoprostol. The higher success rate of complete abortion with the mifepristone and misoprostol regimen was statistically significant compared with the placebo and misoprostol regimen (P < 0.05). CONCLUSIONS: A regimen of mifepristone and misoprostol was significantly more effective for termination of pregnancies < or = 56 days than misoprostol alone. The 88% efficacy obtained with vaginal misoprostol alone may be clinically acceptable when mifepristone is not available.
