Drospirenone is an ingredient in some birth control pills and is used in menopausal hormone therapy. In combination with ethinylestradiol it is used as contraception, and for women who want contraception it is also approved by the U.S. Food and Drug Administration (FDA) to treat moderate acne and premenstrual dysphoric disorder. Although FDA approved, this does come with a higher risk of venous thrombosis than with other contraceptives containing other progestins, and therefore all individuals would have to be individually assessed for appropriateness. Studies have found that the Yaz formulation was superior to placebo in reducing premenstrual emotional and physical symptoms while also improving quality of life.
Angeliq, a drospirenone and estradiol combination, has also been approved by the Food and Drug Administration (FDA) for treatment of moderate to severe vasomotor symptoms and/or vaginal atrophy associated with menopause.
The FDA has several approved indications for drospirenone. It is approved as a first-line therapy for menopause symptoms such as the relief of hot flashes. Additionally, it has been shown to reduce the occurrence of bone fractures in postmenopausal women.
