Abstract

本发明涉及一种用于人工引产的医药复合体,它特别适用于大月份(三个月以上)引产。本发明的复合药物是,在一个给药单元中,复合含有利凡诺、抗孕激素和前列腺素,其中抗孕激素具备与孕激素受体有较强的亲和能力,它对胞膜有支持作用,对子宫肌和子宫颈的胶元分解有抑制作用。它能缩短引产时间,减轻产妇痛苦,且降低医护人员的劳动强度。采用此复合药物,从用药到胎儿娩出,时间短,痛苦少,安全可靠。对初产妇,平均总产程只需四个小时,总有效率为98%;对经产妇,从服药到胎儿娩出,阵痛不明显,平均总产程仅为三个小时,总有效率为100%。

Description

用于大月份引产的复合药物
本发明涉及一种用于人工引产的医药复合体,它特别适用于大月份(三个月以上)引产。
目前人工引产的药物很多,如:R2323(18-甲基三烯炔诺酮)、PG05(15-甲基PGF25)、Ru486(米非司酮)等,其缺点为:引产率不高(80%左右),引产时间长,使用不方便,出血多,只能用于早孕。而单用利凡诺,对于小月份引产,引产率是较高的;但对于大月份(三个月以上)引产,单用利凡诺,不仅引产率成问题,而且引产时间长,出血多,痛感强烈,给产妇造成的痛苦很大;另外,由于引产时间长,产妇需要住院,则医护人员夜间要值班,再加上产妇痛苦的呻吟,使得医护人员身心极度疲劳。
本发明的目的在于提供一种复合药物,它能缩短引产时间,减轻产妇痛感,且降低医护人员的劳动强度。
本发明的复合药物是,在一个给药单元中,复合含有利凡诺、抗孕激素和前列腺素,其中抗孕激素具备与孕激素受体有较强的亲和能力,它对胞膜有支持作用,对子宫肌和子宫颈的胶原分解有抑制作用。
药理分析:人工引产的过程,实际上是人为地终止妊娠的过程。完成这个过程的条件是,子宫颈成熟,然后出现有效宫缩,完成分娩。利凡诺能杀菌,刺激子宫收缩,使子宫肌肉收缩频率及幅度提高,同时,利凡诺能使子宫颈成熟,且变得富有弹性;抗孕激素与孕激素受体有较强的亲和能力,它使子宫肌兴奋,使子宫颈胶原分解力下降,因此,将利凡诺与抗孕激素并用,可使蜕膜细胞坏死,并释放出内源性前列腺素。前列腺素能使子宫收缩,宫颈成熟,黄体溶解,抑制神经兴奋等作用。所以再加入兴奋子宫型前列腺素,必然明显提高子宫对前列腺素的敏感,同时促进宫颈成熟、松弛、扩张。在无明显痛感的情况下,引起子宫强烈收缩,造成流产。
根据本发明,该复合药物中的抗孕激素,可选用以下化合物:
11β-((4-N,N-二甲氨基)-苯基)-17β羟基-17α丙炔基-4,9(10)-雌(甾)二烯-3-酮(Ru486)
11β-P-甲氧苯基-17β-羟基-17α-乙炔基-4,9(10)-雌(甾)二烯-3-酮
11β-((4-二甲基氨基)苯基)-17α-羟基-17β-(3-羟基丙基)-13α-甲基-4,9(10)-性二烯-3-酮
11β-[4-(二甲基氨基)苯基]-17β-羟基-17α-(1-丙炔基)-4-雌烯-3-酮
11β-(4-乙酰基苯基)-17β-羟基-4-雌烯-3-酮
11β-(4-乙酰基苯基)-17β-羟基-17α-(1-丙炔基)-4-雌烯-3-酮
11β-[4-(3-呋喃基)苯基]-17β-羟基-17α-(1-丙炔基)-4-雌烯-3-酮
以上列举的化合物并非全部,凡与孕激素受体有较强亲和能力的抗孕激素,同样适用。
根据本发明,该复合药物中所含的利凡诺,抗孕激素及前列腺素的比例为:1∶1~10∶0.005~0.1,最佳方案为:1∶2~6∶0.008~0.08。使用时,可分隔地、连续地或同时使用。如果需要的话,可适当添加一些阻滞剂,以便延缓利凡诺、抗孕激素或前列腺素释放的时间。该复合药物可以制成丸、胶囊、片剂等形式,进行口服,肠胃内或非经肠用药,优先方式为肠胃内用药。
对五百多例三个月以上孕妇采用此复合药物,从用药到胎儿娩出,时间短,痛苦少,安全可靠。对初产妇,平均总产程只需四个小时,总有效率为98%(剩余2%的孕妇,由于妊娠月份达7、8个月,因此总产程超过四个小时);对经产妇,从服药到胎儿娩出,阵痛不明显,平均总产程仅为三个小时,总有效率为100%。
实施例1:
1).利凡诺100mg,
2).11β-((4-N,N-二甲氨基)-苯基)-17β羟基-17α丙炔基-
4,9(10)-雌(甾)二烯-3-酮(Ru486),150mg,
3).米索1mg,
将1),2)和3)混合后分置于胶囊中。然后给妊娠13周的孕妇服用,开始服药的时间为早上9点,中午12点45左右,胎儿娩出,孕妇基本上没有感觉到痛苦。
实施例2:
将100mg利凡诺,200mg Ru486与1.2mg米索,复合后涂覆在聚氧乙烯/聚氧丙烯膜(PLURONIO F68)上;给妊娠26周的孕妇服用,早上9点开始服药,下午1点50左右,胎儿娩出。孕妇有痛感,但不强烈。
