Abstract

The present invention relates to methods for the prevention and treatment of conditions arising from local estrogen deficiency, such as dyspareunia, vulvar atrophy, vaginal atrophy, vaginal dryness, vulvar itching, vaginal itching, vulvar burning, vaginal burning, vulvar dystrophy, atrophic vaginitis or menopausal sexual dysfunction. In some embodiments, the methods include systemic, for example oral, administration of an estrogen, such as conjugated estrogens, and a progestagen, such as MPA, contemporaneously with local administration of an estrogen, for example conjugated estrogens. In some embodiments, the methods include the oral administration of conjugated estrogens and MPA, and the vulvar, vaginal, or vulvar and vaginal administration of conjugated estrogens, for example in a cream.

Description

field of invention [0001] The present invention relates to methods for the prevention and treatment of conditions caused by localized estrogen deficiency. In some embodiments, the method includes systemically administering an estrogen (eg, conjugated estrogen) and a progestin (eg, medroxyprogesterone acetate (MPA)) concurrently with topical administration of the estrogen. In some embodiments, the method comprises oral administration of the conjugated estrogen and medroxyprogesterone acetate and vulvar, vaginal, or both vulvar and vaginal administration of the conjugated estrogen (eg, in a cream). Background of the invention [0002] Women experience multiple symptoms during menopause, in fact less than 25% of women experience a symptom-free menopausal transition. Menopausal symptoms have a considerable impact on the quality of life (QoL) of women during this period, which are often accompanied by anatomical and physiological changes of the vulva and vagina, decreased vagina...
