Question

Quizplus · Accepted Answer

Mifepristone is a medication used in medical abortions. It works by blocking the action of progesterone, which is necessary to maintain pregnancy. Without progesterone, the uterus lining begins to shed, and the pregnancy cannot continue. Mifepristone is usually followed by a second medication, misoprostol, which causes contractions to further expel the pregnancy tissue.
