Abstract
The antiprogestin mifepristone, in combination with a prostaglandin analogue, has proved effective in terminating pregnancies and has been licensed for early abortion in three European countries and in China. This compound can also be used for contraception, and encouraging results have been reported regarding its emergencypostcoital use, where the efficacy seems higher and the frequency of side-effects lower than for any other hormonal method presently employed. Immediate postovulatory administration ofmifepristone is also effective in preventing pregnancy. Lower doses than those required for inhibition of ovulation disturb the normal development of the endometrium, which opens the way for a new contraceptive method based on very low daily or once weekly administration of mifepristone. Other possible future clinical applications are induction oflabour and the treatment offibroids and endometriosis, once safety and efficacy have been clarified.RésuméAyant fait la preuve de son efficacité pour l'interruption de grossesses, quelque soit leur stade, un antiprogestatif, la mifépristone, associée a un analogue des prostaglandines, a été approuvé dans trois pays européens, ainsi qu'en Chine, comme produit abortif a un stade précoce. Le compose peut aussi être utilise a des fins de contraception, et on a rapporté des résultats encourageants sur son utilisation en administration post-coïtale d'urgence. En pareil cas, il semble avoir plus d'efficacité et moins d'effets secondaires que toute autre méthode hormonale actuellement en usage. L'administration de mifepristone sitot après l'ovulation est également efficace pour prévenir la grossesse. Des doses moins élevées que celles nécessaires pour 1'inhibition de 1'ovulation suffisent a empecher le développement normal de l'endomètre, ce qui ouvre la voie a une méthode contraceptive nouvelle, basée sur la prise d'une dose journalière très faible, ou d'une dose hebdomadaire, de mifépristone. On peut aussi envisager d'autres applications cliniques du produit, une fois bien établies sa securité d'emploi et son efficacité, par exemple pour l'induction du travail et pour le traitement des fibromes et de l'endométriose.ResumenLa antiprogestina mifepristone, combinada con una prostaglandina análoga, ha demostrado su efectividad en la terminación del embarazo en todas sus fases, y ha sido oficialmente aprobada para abortos en las primeras etapas del embarazo en tres paises europeos y en la China. Este compuesto puede ser utilizado también como método anticonceptivo, y los informes sobre su use como método de emergencia postcoito son alentadores: su eficacia parece ser superior y la frecuencia de sus efectos laterales inferior a las de cualquier otro metodo hormonal utilizado hoy en día. La administration de mifepristone inmediatamente después de la ovulación es eficaz también para evitar el embarazo. La administración de dosis inferiores a las requeridas para inhibir la ovulación altera el desarrollo normal del endometrio; to cual allana el camino para la creación de un nuevo método anticonceptivo basado en la administration diaria o semanal de dosis muy bajas de mifepristone. Otros posibles usos clinicos futuros, una vez aclarados los aspectos de seguridad y eficacia, serian la induccion del parto y el tratamiento de fibroides y de la endometriosis.
