What is a common drug for hormone replacement therapy in menopausal women?

Conjugated estrogens are commonly used in hormone replacement therapy (HRT) for menopausal women. These estrogens are derived from the urine of pregnant mares and are a combination of different estrogen compounds. HRT aims to address the symptoms associated with menopause, such as hot flashes, mood swings, and vaginal dryness, which result from decreased estrogen levels in the body. By supplementing with conjugated estrogens, clinicians can help alleviate these symptoms and improve overall quality of life.

The other options do not serve this specific purpose: Medroxyprogesterone is often used in conjunction with estrogen in women who still have a uterus to prevent endometrial hyperplasia but is not used alone for HRT. Hydrocortisone is a corticosteroid used to treat various inflammatory and autoimmune conditions, and Levothyroxine is a thyroid hormone replacement used for hypothyroidism. Therefore, conjugated estrogens are the primary choice for managing menopausal symptoms through hormone replacement therapy.
