A medication commonly used in combination with Misoprostol to carry out medical abortion. It causes blockage of progesterone hormone, a potent hormone needed for normal development of pregnancy. This in turn causes uterine lining degeneration, softening and dilation of the cervix, and the uterus becomes more receptive to the effects of Misoprostol.
Mifepristone also known as RU-486 is a synthetically produced antiprogesterone agent which blocks the progesterone hormone during the early stage of pregnancy. Progesterone is a naturally derived hormone which prepares the lining of the uterus for the implantation of a fertilized egg and helps in maintaining this pregnancy. Without progesterone, the lining of the uterus breaks down, softens and bleeding occurs and so the fertilized egg could not implant in the uterus. Mifepristone also makes the cervix and uterus more sensitive to the effects of Misoprostol. The intake of Mifepristone is usually followed by Misoprostol.
Use Mifepristone as directed by your doctor! Termination of intrauterine pregnancy through 70 days gestation, in a regimen with misoprostol.
