Cenestin
® (
conjugated estrogens) is a prescription medication that contains a mixture of synthetic (manufactured) estrogen hormones. It is approved for treating menopausal symptoms, such as
hot flashes and vaginal dryness.
Cenestin is made by Duramed Pharmaceuticals, Inc.
During and after
menopause, women experience a drop in estrogen levels, as well as a shift in the balance of estrogens that the body produces. Before menopause, the ovaries produce the main source of estrogen, and the main type of estrogen produced is known as estradiol. After menopause, the main source of estrogen is androstenedione, which is produced by the adrenal gland and is converted into an estrogen known as estrone. Menopausal symptoms and changes result from both the decrease in estrogen and the shift from estradiol to estrone.
Cenestin is a mixture of synthetic (manufactured) estrogens. Unlike many other estrogen products, it does not contain any hormones produced by horses. It helps to relieve menopausal symptoms by replacing the estrogen that the ovaries no longer produce.
