The Correct Answer is CMifepristone blocks the action of progesterone, which is needed to sustain a pregnancy. This results in:
- Changes in the uterine lining and detachment of the pregnancy
- Softening and opening of the cervix
- Increased uterine sensitivity to prostaglandin.
Mifepristone is used in combination with another medication - a prostaglandin analogue called misoprostol. Misoprostol causes the uterus to contract and helps the pregnancy tissue to pass.
It is important to note:
- Medical abortion with mifepristone/misoprostol requires at least two visits to a doctor's office or clinic.
- Approximately two-thirds of women will have a complete medical abortion within 4 hours of using the misoprostol.
- Approximately 90% of women will have a complete medical abortion within 24 hours of using the misoprostol.
- Complete abortion generally occurs more quickly when misoprostol is used vaginally rather than orally.
