Documented Uses

• Medicine, biochemical research, oral contraceptives /Estrogen/
• Complex mixture of natural estrogens obtained from equine urine or synthetically from estrone and equilin. Principal components are sodium estrone sulfate and sodium equilin sulfate; also known to contain 17alpha-dihydroequilin, 17alpha-estradiol, and 17beta-dihydroequilin as sodium sulfate conjugates.
• The term "conjugated estrogens" refers to mixtures of at least eight compounds, including sodium estrone sulfate and sodium equilin sulfate, that are derived wholly or in part from equine urine, are plant-based or are manufactured synthetically from estrone and equilin. Conjugated estrogens contain as concomitant components the sodium sulfate conjugates of 17alpha-dihydroequilin, 17beta-dihydroequilin and 17alpha-estradiol.
• For the treatment of moderate to severe vasomotor symptoms due to menopause and for treatment of moderate to severe symptoms of vulvar and vaginal atrophy due to menopause.
• Hormones and Synthetic Substitutes:
• Conjugated estrogen therapy is indicated in the treatment of moderate to severe vasomotor symptoms due to menopause. /Included in US product label/
