Medical abortion
(重定向自Chemical Abortion)
A medical abortion is a type of non-surgical abortion in which abortifacient pharmaceutical drugs are used to induce abortion. An oral preparation for medical abortion is commonly referred to as an abortion pill.
Medical abortion became an alternative method of abortion with the availability of prostaglandin analogs in the 1970s and the antiprogestogen mifepristone (also known as RU-486) in the 1980s.
