每月服用21天的口服避孕药,一般都含有雌激素和孕激素两种成份。这两种成份都有一些不良副作用,为此曾试图将其中的雌激素减少到最低限度,即每片50μg,而孕激素则在初期11天中用含有50μg高诺酮的片子,后期10天中用每片含125μg高诺酮的片子。鉴于正常月经周期中,体内孕激素的水平在初期时是很低的,到中后期才上升,故为了使服药者体内的激素水平更接近于自然,现又进一步把口服避孕药内的两种成份作如下的改变,并改分为三期服药: 初期6天、每天服1种浅棕色药片,每片含高诺酮50μg、乙炔雌二醇30μg。
Take 21 days a month of oral contraceptives, generally contain two components of estrogen and progesterone. Both of these components have some undesirable side effects, for which an attempt was made to minimize estrogen, 50 μg per tablet, while progestin was given in the first 11 days with a tablet containing 50 μg of norgestrel followed by 10 days With each tablet containing 125 g pergolone. In view of the normal menstrual cycle, the level of progesterone in the body at the beginning is very low, only to rise in the late period, so in order to make the hormone levels in the body of the drug closer to the natural, and now further into the oral contraceptives of the two The ingredients were changed as follows and were divided into three doses: the first 6 days, taking 1 light brown tablets daily, each containing gorcycline 50μg, ethinyl estradiol 30μg.
