Purpose of the study- To study the efcacy of mifepristone followed by misoprostol over misoprostol alone in early pregnancy failure in terms of complete evacuation of uterus. METHODS: In a randomized comparative study at the Department of Obstetrics and Gynaecology of Kasturba Hospital, 100 women with early pregnancy failure and gestational age ≤12 weeks between January 2017 and December 2017 were recruited. Of these, 50 women were given a single oral dose of mifepristone (200 mg) followed by 800 mcg misoprostol vaginally (if required) after 24 hours and the other 50 women were treated with 800 mcg misoprostol vaginally alone. RESULTS: Complete evacuation of uterus was achieved in 96% women treated with a sequential combination of mifepristone and misoprostol versus 84% women treated with misoprostol alone. The difference in the rate of complete expulsion was 12% (p <0.05, 95% CI). Also, pre-treatment with mifepristone resulted in statistically signicant reduction in induction to abortion interval (2.40 ± 1.774 vs 3.30 ± 1.951 hr), amount of bleeding (402.2 ± 111.84 vs 535.0 ± 114.84 ml) and duration of bleeding (10.7 ± 2.30 vs 12.4 ± 3.38 days). CONCLUSION Medical treatment of early pregnancy failure with a sequential combination of mifepristone and misoprostol was more effective than misoprostol alone. Hence, women with early pregnancy failure may be offered mifepristone pretreatment before misoprostol to increase the chance of successful management, while reducing the need for surgery.
