【通用名】:结合雌激素软膏

【商品名】:倍美力

【汉语拼音】beimeili

【英文名】:ConjugatedEstrogensCream

【化学名】:

【主要成份】:本药含有从孕马尿液中提取的雌激素混合物,为水溶性雌激素硫酸钠盐混合物。它是雌酮硫酸钠与马烯雌酮硫酸钠的混合物。它还含有硫酸钠结合物、17α-二氢马烯雌酮、17α-雌二醇、17β-二氢马烯雌酮。

【性状】:含天然的、以非液化基形式存在的共轭雌激素,为水溶性配方的白色软膏,无气味。

【药理毒理】:
雌激素药物是通过调节一定数目基因的转录而起作用的。雌激素通过细胞膜扩散,并分布于整个细胞内。在雌激素应答组织中发现的一种DNA结合蛋白,称为核雌激素受体,雌激素与之结合并使之激活。活化的雌激素受体与特异DNA序列或激素应答成分相结合,增强邻近基因转录,从而产生作用。已知妇女生殖器、乳房、脑垂体、下丘脑、肝脏和骨中均有雌激素受体。
雌激素对女性生殖系统和第二性征的发育及维持有非常重要的作用。雌激素通过直接作用使子宫、输卵管和阴道生长发育。雌激素与其他激素,如脑下垂体激素和黄体酮,共同通过促进乳腺管生长、基质发育和脂肪合成使乳房增大。雌激素与其他激素有错综复杂的相互关系,尤其是与黄体酮,在排卵周期和妊娠过程中,可影响脑垂体促性腺激素的释放。雌激素有助于骨骼成形,维持女声及保持泌尿生殖器结构的弹性。雌激素可促使长骨骨骺发生变化,从而影响青春期生长和结束,并使乳晕和阴道色素沉着。
雌激素有多种形式。在周期正常的成年妇女中,雌激素的主要来源是卵泡。根据月经周期相,卵泡每天可分泌70-500ug雌二醇。雌二醇主要转变成雌酮和少量雌三醇。雌酮在循环中的比例大致与雌二醇相似。绝经后,大多数内源性雌激素是雄烯二酮转变而来的。雄烯二酮由肾上腺皮质分泌,并在周围组织中转变成雌酮。因此,雌酮(尤其是其硫酸酯形式)是绝经后妇女循环中含量最高的雌激素。虽然,循环雌激素存在代谢转换的动态平衡,但雌二醇是主要的人体细胞内雌激素,它对受体的作用能力比雌酮或雌三醇更强。
对脂质的作用:对97%的心血管疾病低危白种人群中进行的临床研究结果表明,倍美力可明显增加HDL-C及其HDL2-C,并明显减少LDL-C。
下面总结了用本药治疗1年后,脂质基础参数值变化的平均百分比。
本药0.625mg治疗1年后脂质基础参数值变化的平均百分比
总胆固醇:0.2;
HDL-C:14.1*;
HDL2-C:70.8*;
LDL-C:-7.7*;
甘油三酯:39.4*。
(*与基础值相比有显著差异,P≤0.05)

致癌,致突变及对生育力的损害:在动物,长期持续使用天然或合成雌激素可使乳腺癌、子宫癌、宫颈癌、阴道癌、睾丸癌及肝癌发生率增加。

倍美力是一种从天然物质中提取的雌性激素混合物。在妇女体内雌激素主要由卵巢分泌产生,通常妇女在45-55岁间都会因绝经而减少雌激素分泌。倍美力阴道用软膏能对这种雌激素分泌减少而作为弥补,因而有效地控制与绝经有关的组织变化所引起的阴道及泌尿生殖器方面的失调。

【药物动力学】:倍美力阴道用软膏是阴道给药,它能被人体吸收进而对阴道和泌尿道的组织发挥作用。

【适应症】:用于治疗在阴道部位因雌激素不足而引起的有关组织的病变,这些病变表现为阴道和泌尿系统的内膜干燥、搔痒和疼痛。

【用法用量】:倍美力阴道用软膏的应用方式和使用剂量应由医生根据个人具体情况而决定。请严格遵照医嘱用药。
