Minimal effective dose of mifepristone for medical abortion.
The aim of this study is to compare the effectiveness of 100 mg versus 200 mg mifepristone along with misoprostol for medical abortion in gestation upto 56 days. This is a prospective controlled study. Eighty women seeking medical abortion with a gestation up to 56 days were included in the study. The women were randomly allotted into two groups. They received 100 mg/200 mg mifepristone on day 1 followed by 800 mcg misoprostol two days later. Women who had not aborted completely by day 14, received a repeat dose of 400 mcg misoprostol and were evaluated on day 21 for completeness of the procedure. Five women in both the groups had incomplete abortion by day 14 (12.5%), while one woman in the test group had to undergo dilatation and evacuation on day 3 due to excessive bleeding. By repeating a second dose of misoprostol, all of them aborted completely and the complete abortion rates were markedly improved from 85% and 87.5% in the test and the control group, respectively to 97.5% and 100%, respectively. It may be concluded that 100 mg mifepristone is as effective as 200 mg and appears to be the lowest effective dose for medical abortion.
