title: A randomized comparison of mifepristone and self-administered oral or vaginal misoprostol for early abortion.
abstract: In France, mifepristone in association with orally administered misoprostol is widely used for the early termination of pregnancy (up to 49 days' gestation). In other centers, mifepristone in association with vaginally administered misoprostol has also been used. The aim of the present study was to compare the efficacy and tolerance of mifepristone in association with misoprostol administered orally or vaginally for the termination of pregnancy of up to 49 days' gestation. A total of 237 women were enrolled in the study. All women received 600 mg mifepristone administered orally and 400 microg misoprostol administered either orally (n = 119) or vaginally (n = 118). A second dose of 400 microg misoprostol was administered if women had not expelled the pregnancy within 3 h. Women were randomized into treatment groups according to the day of their admission. The overall success rate was 98.7% and there was no significant difference in efficacy between the two groups. There was one treatment failure in the group in which misoprostol was administered orally. Of those women who aborted within 3 h of administration of the first dose ofmisoprostol, the route of administration ofmisoprostol did not influence the time to abortion. Of the women who received a second dose ofmisoprostol, the time to abortion was shorter in those who received misoprostol orally (52 min versus 77 min). Tolerance was assessed by visual analog scales and was similar for both groups. In both groups, women preferred the oral route of administration.
