How does ethinylestradiol work on the body?
Because ethinyl estradiol belongs to the group of synthetic steroids, then its action is similar to natural estradiol. This hormone actively interacts with estrogen receptors, which are located in the cells of the target. Action comes instantly, because this substance is absorbed rather quickly through the mucous membranes of the body, as well as the skin. Passing through the liver, ethinyl estradiol is oxidized, passing into another form. This process is accompanied by the formation of metabolites that are in an inactive state and are excreted from the body with urine. At the same time the rate of their excretion is different, and depends on the period of pregnancy, as well as the phase of the ovarian cycle in non-pregnant women.
In what cases are drugs prescribed containing ethinylestradiol?
The main effect that ethinyl estradiol, in fact, like estradiol, has on the body is the proliferation (restoration) of the affected mucous membranes. Under its action, epithelial healing takes place, both in the fallopian tubes and cervix, and in the vagina, the external genital organs. In addition, ethinyl estradiol excites motility, by enhancing the action of the corresponding drugs. Also, this hormone has a hypocholesterolemic effect on the body (reduces cholesterol), increasing the level of lipoproteins in the blood. Due to the fact that the sensitivity to insulin increases, the process of utilization of glucose improves.
It is also necessary to mention the fact that this substance is a part of many oral contraceptives .
The most popular drug containing this substance are tablets Ethinylestradiol. However, there are many analogues of ethinyl estradiol. Among them: Estrovagin, Estrokad , Ovestin, Sinestrol , and others.
