Drospirenone, as a part of combined oral contraceptives, has an antiproliferative effect on hyperplastic processes in the organs of the female reproductive system. Individual selection of COCs taking into account the dose and properties of the gestagenic and estrogenic components allows, with contraceptive and non-contraceptive purposes, to prescribe it to women of reproductive age. Intake of COC containing drospirenone + ethinyl estradiol is not associated with impaired drug tolerance due to complaints of soreness and breast engorgement in the first 3 months. 6 months of COCs containing drospirenone + ethinyl estradiol are significantly associated with a decrease in the frequency of clinical and US-signs of dyshormonal dysplasia of the breast. © 2018 Stavropol State Medical University.
