In brief: Interrupts hormones
Mifepristone (aka ru 486) works by interrupting the pregnancy hormones which support the growth of the growing fetus and placenta.
About 48 hours later, another medicine called Misoprostol is taken to help expel the pregnancy. This type of abortion is best done prior to 7 weeks, although sometime can be used even later up to 9 weeks.
