Abstract
INTRODUCTION : Mifepristone (RU 486) is a progesterone receptor modulator with antagonistic properties. It binds strongly to endometrial progesterone receptors, minimally to estrogen receptors, and upregulates androgen receptors. In a placebo-controlled trial low dose mifepristone (RU 486) has been shown to decrease myoma size as well as symptoms. An increase in androgen receptors also contributes to antiproliferative effects. Mifepristone also delays or inhibits ovulation, which may produce amenorrhoea. Direct suppressive effects on endometrial vasculature as well as on reducing stromal vascular endothelial growth factor (VEGF) have also been suggested for reducing menstrual blood loss.
