Abstract: The present invention describes a two-stage pharmaceutical combined preparation for hormonal contraception containing at least 30 daily unit doses, which preparation, in its first stage, comprises as hormonal active ingredient a combination of an oestrogen preparation and, in a dose that is at least sufficient to inhibit ovulation, a gestagen preparation, in single stage form and, in the second stage comprises as hormonal active ingredient an oestrogen preparation only, wherein the first stage comprises a minimum of 25 and a maximum of 77 daily discrete or continuous unit doses and the second stage comprises 5, 6 or 7 daily discrete or continuous unit doses, and wherein the total number of daily units is equal to the total number of days of the desired cycle of a minimum of 30 and a maximum of 84 days.

Abstract: This invention describes the novel use of dissociated competitive progesterone antagonists for the production of a pharmaceutical agent for demand-oriented female birth control (pill on demand), which can be used regardless of the point in the menstrual cycle, in a dosage unit that is to be administered on a one-time basis, whose dosage is below the ovulation-inhibiting dosage.
