Premarin works to replenish the female hormone estrogen in the body, and improves menopausal symptoms with a naturally derived formulation. It contains conjugated estrogen as an active ingredient and has long been used in domestic medical institutions. Premarin exhibits high estrogen activity in the body, and by supplementing estrogen from the outside, it improves unpleasant symptoms such as menopause. It is also used in the treatment of ovarian insufficiency (associated infertility), functional uterine bleeding, symptoms of ovarian deficiency, and vaginitis (elderly, pediatric and non-specific). Replenishment of estrogen, a hormone that is essential for women to maintain their beauty, youth and health, can restore a feminine and moist life.
