The compound is a 19-nor steroid with substitutions at positions C11 and C17 (17 beta-hydroxy-11 beta-[4-dimethylamino phenyl] 17 alpha-[1-propynyl]estra-4, 9-dien-3-one), which antagonizes cortisol action competitively at the receptor level. Mifepristone is a progesterone receptor antagonist used as an abortifacient in the first months of pregnancy, and in smaller doses as an emergency contraceptive. It is also a powerful glucocorticoid receptor antagonist, Mifepristone was the first antiprogestin to be developed and it has been evaluated extensively for its use as an abortifacient. The original target for the research group, however, was the discovery and development of compounds with antiglucocorticoid properties. These antiglucocorticoid properties are of great interest in the treatment of severe mood disorders and psychosis, although a review of published articles was inconclusive on their efficacy, and considered the use of these drugs in mood disorders at 'proof of concept' stage. It is on the World Health Organization's List of Essential Medicines. Applications: Mifepristone is used alone or in combination with misoprostol (Cytotec) to end an early pregnancy. Early pregnancy means it has been 49 days or less since your last menstrual period began. Mifepristone is in a class of medications called antiprogestational steroids. It works by blocking the activity of progesterone, a substance your body makes to help continue pregnancy. Mifepristone is also available as another product (Korlym), which is used to control hyperglycemia (high blood sugar) in people with a certain type of Cushing's Syndrome in which the body makes too much of the hormone cortisol. This monograph only gives information about mifepristone (Mifeprex), which is used alone or in combination with another medication to end an early pregnancy. If you are using mifepristone to control hyperglycemia caused by Cushing's syndrome, read the monograph entitled mifepristone (Korlym) that has been written about this product.
