Understanding Mifepristone

Mifepristone is a medication that serves several key medical purposes. Initially approved by the FDA in 2000 for the medical termination of a pregnancy, its applications have broadened over the years. For more on its usage, visit What Is Used For.

Medical Uses of Mifepristone

Mifepristone in Medical Abortion

The most recognized use of mifepristone is in combination with misoprostol for medical abortion. This combination is typically effective up to 10 weeks into a pregnancy.

• Effectiveness: The regimen is approximately 95-98% effective.
• Process: Mifepristone is taken first to block progesterone, followed by misoprostol to induce contractions and expel the pregnancy.

Treatment of Cushing’s Syndrome

Mifepristone is also FDA-approved for the treatment of Cushing’s syndrome, a disorder caused by high cortisol levels.

• Mechanism: It helps manage blood sugar levels by counteracting cortisol’s effects.
• Usage: It is prescribed for individuals with type 2 diabetes or glucose intolerance due to the syndrome.

Role in Cancer Treatment

Emerging research highlights mifepristone’s potential in treating certain cancers, such as breast cancer and meningioma.

• Action: It inhibits cancer cell proliferation by blocking hormone receptors that fuel tumor growth.

How Mifepristone Works

Mifepristone functions as an antiprogestogen, meaning it blocks progesterone, a hormone crucial for pregnancy maintenance and certain cellular functions.

• For Abortion: It detaches the gestational sac from the uterine wall.
• For Cushing’s Syndrome: It mitigates cortisol-related effects.
• For Cancer: It inhibits hormone receptors involved in cancer progression.

Considerations and Side Effects

As with any medication, mifepristone comes with its considerations and potential side effects.

• Common Side Effects: Include cramping, bleeding, nausea, dizziness, and fatigue.
• Contraindications: Not recommended for individuals with adrenal failure, bleeding disorders, or on long-term corticosteroid therapy.
