What are conjugated estrogens?

Conjugated estrogens are mixtures of man-made or natural estrogens used as an external source and replacement for the natural female hormone. Estrogens have widespread effects on many tissues in the body. Estrogens cause growth and development of the female sexual organs and maintain female sexual characteristics such as the growth of underarm and pubic hair, body contours, and skeleton. Estrogens also increase secretions from the cervix and growth of the inner lining of the uterus (endometrium).

Menopausal women produce less estrogen which leads to symptoms of hot flashes, vaginal dryness, shrinking in vaginal tissue and painful intercourse. Using conjugated estrogens can help treat such symptoms in menopausal women. Conjugated estrogens can also help in prevention of bone loss in menopausal women.

What are examples of conjugated estrogens available in the US?

Examples of oral conjugated estrogens are:

Premarin vaginal cream is a topical form of estrogen.

Enjuvia and Cenestin are synthetic conjugated estrogens produced from plant material.

Premarin is derived from natural sources and blended to approximate the composition of estrogens found in urine of pregnant horses.
