作者曾指出,阴道途径应用口服避孕药是生育调节的一种有效的可接受的方法。含有几种避孕甾体的复方药丸也曾取得不同程度的临床试验成功。使用最多的阴道用避孕药丸(VCP)含有500μg 消旋-18甲基炔诺酮和50μg 乙炔雌二醇。此丸剂的用法像口服避孕药那样每天阴道应用,连用21天,可抑制妇女排卵。其它 VCP 还有①炔诺酮1mg 加乙炔雌二醇甲酯50μg,②左旋18-甲基炔诺酮250μg 加乙炔雌二醇50μg,③醋酸氯羟甲稀孕酮2mg 加乙炔雌二醇50μg。
The authors have pointed out that the vaginal route of oral contraceptive use is an effective and acceptable method of fertility regulation. Compound pills containing several types of contraceptive steroids have also achieved varying degrees of clinical success. The most commonly used vaginal contraceptive pill (VCP) contains 500 μg racemic-18 norethindrone and 50 μg ethinyl estradiol. The pill usage as oral contraceptives daily vaginal application, once every 21 days, can inhibit ovulation in women. Other VCP also ① norethindrone 1mg plus ethinyl estradiol methyl ester 50μg, ② levonor 18-norgestrel 250μg plus ethinyl estradiol 50μg, ③ chlormeraldol acetate 2mg plus ethinyl estradiol 50μg .
