[Female contraception by a normal dose progestogen after 40 years of age. Possible association of nomegestrol--17-beta-estradiol acetate by percutaneous route].
Although fertility declines with age, the use of an effective contraceptive remains necessary in women over 40. Endocrine disorders, which are common in this age group, may also often require control. Conventional estroprogestogens, even those of the latest generation, cannot be used in women with a high cardiovascular risk, since age cannot be totally excluded as a possible risk factor. The contraceptive use of derivatives of 17-hydroxyprogesterone and 19-norprogesterone offer a promising alternative, despite the absence of any exhaustive investigation particularly in situations in which the blood level of estradiol has to be reduced. There are, however, some women who respond to this type of contraception by menstrual cycle irregularities, and sometimes by low blood levels of estradiol, regardless of the drug used. A preliminary study is described in which 5 mg of nomegestrol acetate was combined with 17-beta-estradiol by transcutaneous route and which has so-far demonstrated sustained contraceptive efficacy as well as excellent clinical and metabolic safety.
