Medication abortions, which are used up to 10 weeks into a pregnancy, consist of taking two pills in sequence. The first pill in the regimen, mifepristone, loosens the pregnancy's attachment to the uterus. The second pill, misoprostol, forces the uterus to contract to push out the pregnancy. The pills must be taken consecutively to complete the abortion, and there's a chance the pregnancy will continue if the second pill is not taken.
药物流产用于孕期10周及10周以下的妇女,分两步服两种药。疗程中的第一种药是米非司酮,能降低胚胎对子宫的附着度。第二种药是米索前列醇,能使子宫收缩,促使胚胎排出。这两种药必须连续服用以完成流产,若未服用第二种药,妊娠有可能继续。
A total of 862,320 abortions were provided in clinical settings in 2017, according to the Guttmacher Institute, about 39 percent of which were medication abortions. Research has shown that using these drugs is a safe way to end a pregnancy.
根据古特马赫研究所的数据,2017年共有862320起堕胎在临床环境下进行,其中约39%是药物流产。研究表明,用药物流产是终止妊娠的安全方式。
Some antiabortion activists and legislators claim that not taking the second pill, or giving a woman high doses of the hormone progesterone after taking mifepristone, can help stop, or "reverse," a medical abortion.
一些反堕胎活动家和立法者称,不服用第二种药物,或者在妇女服用米非司酮后让她们服用大剂量的荷尔蒙孕酮能够帮助终止或者“逆转”药物流产。
