[Trends since 1989, in France, of induced abortions by mifepristone (RU486) combined with a prostaglandin analogue].
In 1989 the French Ministry of Health gave its agreement to the utilisation of the combination mifepristone + a prostaglandin analogue for abortion up to 49 DA. Since then, research activities have been carried out to improve this method. Research to define the best prostaglandin analogue: sulprostone and gemeprost were dropped out; misoprostol was authorized in 1992 following very convincing trials, it is now commonly used and has never generated any major problem. Research to extend the application time limit to 63 DA: it showed a significant drop in efficiency (86.8% instead of 95.4%) as well as an increase of the rate of haemorrhages (2.25% instead of 0.3%). Therefore the method currently used reads as follows. Day 1: mifepristone 600 mg, day 3: misoprostol 400 micrograms, day 10-15: control visit. The efficiency rate is 95.4%; an additional dose of 400 micrograms of misoprostol 3 hours after the first dose if no expulsion has occurred, increases the rate up to 98.5%. This method is well accepted by women as it enables an early abortion and avoids surgery and anesthies. The arrangements required to implement the method are not easy to make as they call for a change of habits by the institutions as well as by medical teams.


CONCLUSIONS
Since the use of misoprostol, the abortion by mifepristone using. 400 micrograms + 400 micrograms of misoprostol has become a method which is safe, efficient and much appreciated by women, but it implies a change in the usual practice of abortion.
