Guidelines 2016 – Medical Abortion

Guidelines 2016 – Medical Abortion
Guidelines for Nurse Practitioners in Gynecologic Settings 2016

I. DEFINITION
A medical abortion terminates a pregnancy as early as pregnancy can be confirmed, but no later than 63 days from the last menstrual period, with the use of misoprostol and mifepristone. The shorter the time a woman has been pregnant, the better the medications work (National Abortion Federation [NAP], http://prochoice.org).
A. Mifepristone (Mifeprex): a derivative of norenthindrome with a strong affinity for progesterone receptors. The progestin antagonist effect of mifepristone interferes with the maintenance of early pregnancy. Mifepristone acts on the deciduas to break down the capillary epithe- lial cells, causing the trophoblast to separate from the decidua. This leads to the disruption of the integrity of the pregnancy, bleeding, and a decrease in maternal human chorionic gonadotropin (hCG).
B. Misoprostol (Cytotec; also known as RU-486): a synthetic prostaglandin analogue. Misoprostol efficiently ripens the cervix and induces uter- ine contractility. Misoprostol tablets are taken within a few days of taking mifepristone (Mifeprex) and may be taken orally, placed into the vagina, or tucked between the cheek and gum.
