2001年7月31日《Medscapewire》报道,两种实验中的新药可能会使女性跳过她们的月经期,并提供一种可替代传统避孕方法的新途径。 位于Beaverton的俄勒冈州灵长动物中心的研究人员说,ZK137 316和ZK230 211是两种抗孕激素药物,并已经通过在动物身上的一期实验。这两种药可以抑制行经和排卵,但有可逆性。抗孕激素药物具有阻断孕酮作用的分子,而孕酮是与月经相关的使子宫内膜形成和脱落的激素。 July 31, 2001, “Medscapewire” reported that new drugs in both experiments may have made women skip their menstrual periods and provide a new avenue to replace the traditional methods of contraception. Researchers at the Oregon Primate Center in Beaverton say the ZK137 316 and ZK230 211 are two antiprogestin drugs and have passed an experiment in animals. Both drugs inhibit menstruation and ovulation, but are reversible. Anti-progesterone drugs block the action of progesterone molecules, and progesterone is associated with the menstrual hormone to make the formation and shedding of the endometrium.
