USE OF COMPETITIVE PROGESTERONE ANTAGONISTS FOR PRODUCING PHARMACEUTICAL COMPOSITIONS FOR REGULATING FEMALE FERTILITY AS REQUIRED

摘要

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.
