  • Use of low levels of mifepristone to treat leiomyomata
    Patent number: 5468741
    Abstract: This invention provides for novel unit doses of mifepristone to treat leiomyomata. Compared to unit dosages taught by the prior art, the claimed dosages are low and surprisingly effective. Furthermore, because higher dosages had undesired side effects, the prior art suggested that mifepristone was not suitable for long term clinical uses which are needed to treat leiomyomata. The advantages of this invention include a reduction of surgical morbidity, circumvent the need of a hysterectomy, and cost-effectiveness.
