代谢
(14)C-Norgestrel 给七名受试者服用后,5天内尿液中排出了剂量的43%... 酶水解仅释放了尿液中放射性活度的32%,另外25%以硫酸盐结合物的形式排出。尿液中排出的代谢物比服用相关化合物如norethisterone或lynestrenol后的代谢物极性要小得多。从尿液中分离出了四氢诺孕酮的3alphaOH,5beta和3betaOH,5beta异构体(13beta-ethyl-17alpha-ethynyl-5beta-gonane-3alpha,17beta-二醇),并通过质谱、薄层色谱和气液色谱进行了鉴定。血浆中的放射性活度下降速度比服用norethisterone和lynestrenol后要快。大约2%的服用剂量转化为了酸性化合物。无论是口服还是静脉给药,norgestrel的放射性活度排出速率或代谢物似乎没有明显差异。
(14)C-Norgestrel was administered to seven human subjects and 43% of dose was excreted in the urine within 5 days ... Enzymic hydrolysis released only 32% of the urinary radioactivity and a further 25% was excreted as sulphate conjugates. The metabolites excreted in the urine were much less polar than those following the administration of the related compounds, norethisterone or lynestrenol. The 3alphaOH,5beta and 3betaOH,5beta isomers of the tetrahydronorgestrel (13beta-ethyl-17alpha-ethynyl-5 beta-gonane-3alpha,17beta-diol) were isolated from urine and identified by mass spectrometry and thin-layer and gas-liquid chromatography. Plasma radioactivity decreased more rapidly than after the administration of norethisterone and lynestrenol. About 2% of the administered dose was converted to acidic compounds. There was no apparent difference in the rate of excretion of radioactivity or in the metabolites after either oral or intravenous administration of norgestrel.

代谢
在非洲绿猴(Cercopithecus aethiops)中研究了dl-、d-和l-诺孕醇的相对代谢情况。单次口服给予(14)C-dl-诺孕醇(1 mg/kg)后,尿液中的总(14)C排泄量(51.4 +/- 5.0%)显著高于给予d-对映体后的排泄量(37.5 +/- 5.4%),但与给予l-对映体后的排泄量(44.2 +/- 8.9%)无显著差异。在所有情况下,尿液中放射性物质的主要部分以游离分数存在(48-62%),而另外13-27%的放射性物质可以通过β-葡萄糖醛酸酶制剂释放。未检测到硫酸盐结合物。至少有一个主要(16beta-羟基化)和一个次要(16alpha-羟基化)的代谢途径具有立体选择性,即它们作用于l-对映体而非d-对映体。三种代谢物,16beta-羟基诺孕醇、16alpha-羟基诺孕醇和16-羟基四氢诺孕醇(认为是16beta)仅在给予(14)C-dl-和-l-诺孕醇的动物尿样中检测到。在给予(14)C-d-诺孕醇后,3alpha, 5beta-四氢诺孕醇被发现是主要的尿液代谢物。这些观察结果与之前在女性中报道的dl-诺孕醇尿液代谢物进行了比较。
The comparative metabolism of dl-, d-, and l-norgestrel was investigated in African Green Monkeys (Cercopithecus aethiops). Total (14)C excretion in urine after a single oral dose of (14)C-dl-norgestrel (1 mg/kg) was significantly higher (51.4 +/- 5.0%) than that observed after administration of the d-enantiomer (37.5 +/- 5.4%) but not the l-enantiomer (44.2 +/- 8.9%). In all cases, the major part of the urinary radioactivity was present in a free fraction (48-62%), while an additional 13-27% was released by beta-glucuronidase preparations. No sulfate conjugates were detected. At least one major (16beta-hydroxylation) and one minor (16alpha-hydroxylation) metabolic pathway were stereoselective, i.e., they are operative with the I-but not the d-enantiomer. Three metabolites, 16beta-hydroxynorgestrel, 16alpha-hydroxynorgestrel, and 16-hydroxytetrahydronorgestrel (believed to be 16beta) were only detected in urine samples obtained from (14)C-dland -l-norgestrel-dosed animals. Following (14)C-d-norgestrel administration, 3alpha, 5beta-tetrahydronorgestrel was found to be the major urinary metabolite. These observations are compared with those reported earlier on the urinary metabolites of dl-norgestrel in women.

代谢
体外对诺孕醇立体异构体(D型、L型以及外消旋混合物DL)的代谢进行了研究,使用的是兔肝微粒体部分。生物活性较强的L-诺孕醇的代谢速度比生物活性较低的D-诺孕醇快。这主要是由于L-诺孕醇更容易转化为环A还原代谢物。两种异构体在羟基化方面的量没有差异;大约30%的每种异构体在30分钟孵化后被转化为羟基化代谢物。然而,两种异构体之间存在差异,L-诺孕醇主要转化为16beta-羟基甾体,而D-诺孕醇转化为16alpha-羟基甾体。两种异构体在C-6位置上羟基化的量相似。外消旋混合物的代谢速度介于D型和L型异构体之间。
The in vitro metabolism of stereo-isomers (d, l and the racemic mixture dl) of norgestrel by a microsomal fraction from rabbit liver was investigated. The metabolism of the biologically active l-norgestrel was more rapid than that of d-norgestrel (sic.) which is biologically inactive. This was mainly due to the more ready conversion of l-norgestrel to ring-A reduced metabolites. There was no difference between the two isomers in respect of the amount undergoing hydroxylation; about 40% of each isomer was converted to hydroxylated metabolites after 30 min incubation. However, there were differences between the isomers, l-norgestrel being converted mainly to the 16beta-hydroxysteroid and d-norgestrel to the 16alpha-hydroxysteroid. Similar amounts of both isomers were hydroxylated at C-6. The metabolism of the racemic mixture was intermediate between that of the d and l isomers.

19-诺睾酮衍生的合成孕激素在大白兔体外肝脏组织中的代谢速率进行了比较。在1小时的时间范围内,炔雌醇的代谢速度与19-诺睾酮相当,而d-诺孕酯和利奈孕醇的代谢速率略低。不到5%的l-诺孕酯被代谢。在所有情况下,反应产物都是四氢孕激素。利奈孕醇通过炔雌醇进行代谢。骨骼肌、肺和小肠也能代谢炔雌醇和d-诺孕酯,但速率比肝脏组织慢。少量炔雌醇被脂肪组织代谢,但心脏和脾脏无活性。利奈孕醇和l-诺孕酯没有被所研究任何的肝外组织代谢。
The rates of metabolism of synthetic gestagens derived from 19-nortestosterone by rabbit liver tissue in vitro were compared. Over a period of 1 hr norethisterone was metabolized as rapidly as 19-nortestosterone whereas d-norgestrel and lynestrenol were metabolized at a slightly lower rate. Less than 5% of l-norgestrel was metabolized. In all cases the reaction product was the tetrahydrosteroid. Lynestrenol was metabolised through norethisterone. Skeletal muscle, lung and small intestine also metabolized norethisterone and d-norgestrel but at a slower rate than liver tissue. Small amounts of norethisterone were metabolized by adipose tissue but heart and spleen were inactive. Lynestrenol and l-norgestrel were not metabolized by any of the extra-hepatic tissues studied.

体外研究对口服避孕药中使用的3种类固醇(炔雌醇、左炔诺孕酮和甲孕酮)通过小块人空肠粘膜进行了代谢研究。这样做是因为已知人类胃肠粘膜能代谢多种药物。在孵化后,炔雌醇代谢了几乎40%,左炔诺孕酮代谢了9.8%,甲孕酮代谢了7%。所有这些代谢反应与对照组有显著差异。研究结果表明,炔雌醇的代谢与所用组织的重量有关。这些结果与已知的炔雌醇明显的一过效应相一致。已知诺孕酮的一过效应很小或没有,因此没有显示出高的肠道代谢率。在实验条件下,炔雌醇或左炔诺孕酮的I相代谢不明显。
In vitro studies were conducted on the metabolism of 3 steroids used in OCs (oral contraceptives) by small pieces of human jejunal mucosa. This was done because the gastrointestinal mucosa of humans is known to metabolize a number of drugs. Almost 40% of the ethinyl estradiol, 9.8% of the levonorgestrel, and 7% of the mestranol were metabolized after incubation. All these metabolic responses were significantly different from those in the control groups. Results of the study show that the metabolism of the ethinyl estradiol was related to the weight of the tissue used. These results are consistent with the known marked 1st pass effect of ethinyl estradiol. Norgestrel, known to have little or no 1st pass effect, did not show a high rate of gut metabolism. Under the experimental conditions employed, no Phase 1 metabolism of either ethinyl estradiol or levonorgestrel was apparent.

吸收、分配和排泄
不同合成类固醇(用于激素避孕)与性激素结合球蛋白(SHBG)的结合能力通过测量它们在竞争性蛋白结合系统中取代放射性标记的睾酮的能力进行研究。只有19-去甲睾酮衍生物具有显著取代睾酮的能力,d-诺孕酯(d-Ng)是最强的取代剂。在SHBG水平增加的女性中,之前恒定的血浆d-Ng水平增加了两到六倍。因此,可以得出结论,SHBG是d-Ng的主要载体蛋白。d-Ng强烈的睾酮取代活性也可能解释含d-Ng的口服避孕药观察到的雄激素样副作用。
The binding of different synthetic steroids, used in hormonal contraception, to Sex Hormone Binding Globulin (SHBG) was studied by measuring their ability to displace tritiated testosterone from SHBG in a competitive protein binding system. Only 19-nortestosterone derivates had any significant ability to displace testosterone from SHBG, d-norgestrel (d-Ng) being the strongest displacer. Increasing the SHBG levels in women with previous constant plasma d-Ng levels increased these levels two- to sixfold. It is concluded that SHBG is the main carrier protein for d-Ng. The strong testosterone displacing activity of d-Ng might also explain androgenic side effects observed with d-Ng containig oral contraceptives.

制备方法与用途

概述

左炔诺孕酮是一种速效、短期口服避孕药,通过显著抑制排卵和阻止孕卵着床,并使宫颈黏液稠度增加,精子穿透阻力增大,从而发挥速效避孕作用。目前,单用孕激素或与雌激素配伍的左炔诺孕酮已制成多种类型的女性避孕药,以口服、外用及注射等方式达到避孕目的。

药理作用

左炔诺孕酮是一种强效孕激素,其孕激素作用约为炔诺酮的5~10倍,并具有雄激素和抗雌激素活性。该药物主要通过抑制排卵来发挥作用。此外,它还能改变宫颈黏液性质,使精子难以穿透;同时,它还可以使子宫内膜变薄,不利于受精卵着床。

用法用量
  • 短效口服避孕药:从月经第5天开始,每天服1片(丸),连服22天。停药后2~4天来月经,然后于第5天继续服用下一个月的药。
  • 探亲避孕药:于探亲当晚开始服炔诺孕酮探亲避孕药,每天1片,服法同短效口服避孕药。
  • 事后避孕药:房事后72小时内口服2片复方炔诺孕酮事后避孕片,12小时后再服2片。
不良反应

常见不良反应包括胃纳差、痤疮、液体潴留和水肿、体重增加、过敏性皮肤炎症、精神压抑、乳房疼痛、女性性欲改变、月经紊乱、不规则出血或闭经。少见的不良反应有头痛,胸、臀、腿特别是腓肠肌处疼痛,手臂和脚无力、麻木或疼痛,突然的或原因不明的呼吸短促,突然语言发音不清,突然视力改变、复视、不同程度失明等。长期应用可能引起肝功能异常,缺血性心脏病发生率上升,妊娠早期时应用可能导致雄激素活性高引起的后代女婴男性化以及生殖道畸形(多见为尿道下裂)。

药物相互作用
  • 与利福平、氯霉素、氨苄西林、苯巴比妥、苯妥英钠、扑米酮、甲丙氨酯、氯氮平、对乙酰氨基酚及吡唑酮类镇痛药(保泰松)等同服可产生肝微粒体酶效应,加速炔酮在体内的代谢,导致避孕失败、突破性出血发生率增高。
  • 维生素C能增强口服避孕药的作用,每天口服1g维生素C可使炔雌醇生物利用度从40%提高到60%~70%。
  • 与环孢素合用,可抑制环孢素的代谢清除,致其毒性增强,应避免合用。
规格
  • 复方炔诺孕酮一号片(或滴丸):每片(丸)含炔诺孕酮0.3mg和炔雌醇0.03mg。
  • 炔诺孕酮探亲避孕片:每片含炔诺孕酮3mg。
  • 复方炔诺孕酮事后避孕片:每片含炔诺孕酮1mg和炔雌醇0.1mg。
化学性质

左炔诺孕酮为白色或类白色结晶性粉末,无臭、无味。不溶于水,溶于氯仿,微溶于甲醇。

用途

用于避孕药。

    摘要:
    本发明涉及一种用于月经周期调节的性激素类固醇药物的给药方法、配方和递送系统。该发明在临床应用中用于妊娠间隔和月经功能障碍的治疗。孕激素和雌激素在治疗周期中被给予,模拟正常月经周期中的性激素激素。类固醇治疗周期被分为任意和离散的卵泡期和黄体期段,从月经开始时开始。在卵泡期的早期段,不给予外源性类固醇。根据患者的临床和/或生理情况,随后给予不受抵抗的孕激素或雌激素。在首选实施例中,随后是早期黄体期,以低剂量的联合雌激素/孕激素给药;中期黄体期给予足以抑制垂体FSH和LH并维持子宫内膜的雌激素和孕激素;最后,给予减少剂量的联合雌激素/孕激素。该方法和配方的临床成功不仅取决于给予的孕激素分子的生物学效力,还取决于外源性雌激素、孕激素和联合雌激素/孕激素的给药剂量和时间关系。因此,任何FDA批准的合成雌激素或孕激素,在药理学上适当剂量下,均适用于本发明的配方。通过下丘脑-垂体节律而非持续的FSH、LH、内源性雌激素抑制实现月经周期调节和有效避孕。同时,还实现了减少同时给予高剂量雌激素和孕激素的不良内分泌和代谢影响的暴露。在停止使用本发明的给药后,迅速的FSH和随后的LH恢复发生,为正常排卵患者提供适当的排卵和适当的月经。该方法和配方还允许医生采取生理纠正措施,治疗可能或可能不寻求避孕的月经功能障碍患者,这些患者表现为低雌激素、正常雌激素或高雌激素的排卵功能障碍或无排卵。
