COMBINATION OF PROGESTERONE ANTAGONISTS AND ANTI-OESTROGENS WITH PARTIAL AGONISTIC ACTION FOR USE IN HORMONE-REPLACEMENT THERAPY FOR PERI- AND POST-MENOPAUSAL WOMEN

This invention describes the use of at least one compound having a progesterone-antagonistic (PA) action and at least one compound having an antiestrogenic (A?) action with a simultaneous partial agonistic action for the production of pharmaceutical agents for hormone substitution therapy (HRT) for perimenopausal and postmenopausal women. In the case of combined use of progesterone antagonist and antiestrogen, the stimulation of the endometrium by the progesterone antagonist that is caused by its partial agonistic action when an antiestrogen is used by itself is inhibited. For example, a pharmaceutical agent according to the invention contains onapristone (progesterone antagonist) and tamoxifen (antiestrogen).
