Quizplus · Accepted Answer

Mifepristone is a progesterone receptor antagonist, which means it blocks the action of progesterone. Progesterone is necessary for the maintenance of pregnancy, so Mifepristone induces abortion by blocking the action of progesterone in the uterus, leading to the breakdown of the uterine lining and the expulsion of the fertilized egg.
