Which drug is commonly used for hormone replacement therapy in menopausal women?

• A. Progestin
• B. Estrogen
• C. Testosterone
• D. Oxytocin

Answer: (B)

Estrogen is a primary component of hormone replacement therapy (HRT) used in menopausal women. As women reach menopause, the production of estrogen by the ovaries significantly decreases, leading to various symptoms such as hot flashes, night sweats, vaginal dryness, and mood changes. HRT with estrogen helps alleviate these symptoms and provides protective effects against osteoporosis and heart disease that may develop post-menopause.

In this therapeutic context, estrogen replacement can be administered alone or in combination with progestins for women who have not undergone a hysterectomy, as progestins help counteract the risk of endometrial hyperplasia associated with unopposed estrogen therapy.

While other hormones like progestin are important in specific situations within HRT, particularly for women with an intact uterus, it is estrogen that forms the cornerstone of treatment for managing menopausal symptoms. Testosterone is typically not used for this purpose, and oxytocin is primarily involved in childbirth and lactation, making them less relevant options in the context of menopausal hormone replacement therapy.
