The present invention relates to the treatment of estrogen-dependent hyperproliferative uterine disorders including endometriosis, uterine fibroids, endometrial hyperplasia, uterine cancer, and their related symptoms by intravaginally administering at least two active agents selected from an aromatase inhibitor, an antiinflammatory agent, and a uterine-selective estrogen receptor antagonist. This combination therapy reduces local estrogen production, blocks local estrogen action, and suppresses inflammation locally, resulting in starvation of the estrogen-dependent diseased tissues, relief of related symptoms, and retardation of disease progression. Intravaginal delivery maximizes local inhibition of estrogen production without significantly affecting systemic circulating estrogen levels. This results in enhanced clinical efficacy and reduced side effects.
