Premarin – estrogen drug. It contains a mixture of naturally occurring equine estrogens (conjugated estrogens), which are similar to endogenous estrogens. In target tissues (organs of the female urogenital system, breast, hypothalamus, pituitary) estrogens penetrate into the cells and binding to estrogen receptors nuclei regulate RNA and protein synthesis, causing metabolic effects.
The drug is easier and relieves climacteric syndrome associated with estrogen deficiency: vasomotor disorders (including hot flashes) and urogenital symptoms (atrophic vaginitis and atrophic urethritis).
Premarin prevents the development of post-menopausal osteoporosis, reduces bone resorption, but does not stimulate bone formation.
The drug increases the level of HDL cholesterol, lowers LDL and total cholesterol levels, thereby reducing the risk of cardiovascular disease.
When using Premarin as replacement therapy in female hypogonadism or primary ovarian failure is noted the appearance of secondary sexual characteristics in patients.

Application of Premarin
Premarin is used to treat conditions that occur in women during menopause and post-menopause.
- vasomotor disorders of varying severity caused by estrogen deficiency (hot flushes, sweating);
- atrophic vaginitis, atrophic urethritis;
- prevention and treatment of osteoporosis induced by estrogen deficiency;
- reducing the risk of coronary heart disease and associated mortality in postmenopausal women;
- gipoestrogenizm female (female hypogonadism or primary ovarian failure).
