Mechanism of Action
Mifepristone is an anti-progesterone, which blocks the action of progesterone. Progesterone helps maintain the lining of the uterus, but when it is blocked, it can cause the uterus to shed its lining, which leads to the expulsion of the pregnancy. Misoprostol is a prostaglandin, which causes the uterus to contract and helps expel the pregnancy.
How Long Does It Take to Work?
Mifepristone and Misoprostol usually take about two to four hours to work. Most women will experience bleeding and cramping, which may last a few hours or up to a few days. In some cases, a second dose of Misoprostol may be necessary.
Absorption
Mifepristone and Misoprostol are both rapidly absorbed after oral administration. Mifepristone is rapidly metabolized to its active metabolites, which can be detected in the blood within 2-3 hours.
Route of Elimination
Mifepristone and Misoprostol are both primarily eliminated in the feces. The metabolites of mifepristone can also be found in the urine.
Dosage
This can only be prescribed by qualified medical professionals who are able to assess the gestational age of an embryo and to diagnose ectopic pregnancies. The qualified medical professionals must also be able to provide surgical Intervention/MVA (Manual Vaccum Aspiration) in cases of incomplete abortion or severe bleeding or have made plans to provide such care through others and be able to assure patient access to medical facilities equipped to provide blood transfusions and resuscitation, if necessary.Day 1 (First visit): Mifepristone administration: One tablet of Mifepristone (200 mg) is taken in a single oral dose under the supervision of a qualified medical professional in a clinic, medical office or hospital.
Day 2 (Second visit): Misoprostol administration: 24-48 hours after ingesting the Mifepristone tablet, the patient takes four 200 microgram tablets (800 micrograms) of Misoprostol buccally or sublingually. Misoprostol tablets can be administered by the patient herself (place two tablets on each side of cheeck & gum or under the tongue). She should wait for 30 minutes. During the period immediately following the administration of Misoprostol, the patient may need medication for cramps or gastrointestinal symptoms. The patient should be given instructions on what to do if significant discomfort, excessive bleeding or other adverse reactions occur and should be given a phone number to call if she has questions following the administration of Misoprostol.
Day 10 to 14 (Third visit): Post-treatment examination: Patients must return to the clinic, medical office or hospital within 10 to 14 days after the administration of mifepristone. This visit is very important to confirm by clinical examination or ultrasonographic scan that a complete termination of pregnancy has occurred.
Patients who have an ongoing pregnancy at this visit have a risk of fetal malformation resulting from the treatment. Surgical termination/MVA is recommended to manage Menstrual Regulation (MR)/termination of pregnancy failures.
