Efficacy of two intervals and two routes of administration of misoprostol for termination of early pregnancy a randomised cotrolled equivalence trial
BACKGROUND: The most effective route and best interval between several doses of misoprostol to induce abortion have not been defined. Our aim was to assess the effects of the interval between multiple doses of misoprostol and the route of administration to terminate pregnancy. METHODS: 2066 healthy pregnant women requesting medical abortion with 63 days or less of gestation were randomly assigned within 11 gynaecological centres in six countries to the four treatment groups (three doses of 0.8 mg misoprostol given sublingually at 3-h intervals, vaginally 3 h, sublingually 12 h, and vaginally 12 h), stratifying by gestational age. This was an equivalence trial with a 5% margin of equivalence. The primary endpoints were efficacy of treatment to achieve complete abortion and to terminate pregnancy. The main efficacy analysis excluded women lost to follow-up. This trial is registered as an International Standard Randomised Controlled Trial, number ISRCTN10531821. FINDINGS: Efficacy outcomes were analysed for 2046 women (99%), excluding 20 lost to follow-up.
