Estrovagin is a topical estrogen drug.

Release form and composition

Pharmacological properties

Pharmacodynamics

The active substance of Estrovagin - estriol - is an analogue of the natural female hormone. It is used to treat symptoms and conditions caused by a lack of estrogen in women before and after menopause, including surgery.

The drug has a specific colpo- and urotropic activity, therefore it shows high efficiency in urogenital disorders.

It has a selective effect, mainly on the vagina, vulva and cervix. Estriol stimulates blood supply, normalizes the vaginal microflora and the pH of the vaginal environment, helps to restore the epithelium of the vagina and cervix during atrophic changes during premenopause and menopause, affects the quantity and quality of cervical mucus, increases the resistance of the epithelium to inflammatory and infectious processes.

Unlike other estrogens, estriol interacts with sensitive structures for a short time, within 2-4 hours. Due to this, the use of Estrovagin 1 time per day does not contribute to the passage of endometrial proliferation. Therefore, you do not need to use additional progestogens. At the same time, there are no withdrawal bleeding in the postmenopausal period.

Pharmacokinetics

With intravaginal use, the maximum concentration of the drug is achieved within 1-2 hours. In the case of atrophic changes in the vaginal mucosa in the first 3-4 months, there is an increase in the absorption of the drug, as the structure is restored, absorption decreases.

From the body, estriol is excreted mainly in the form of metabolites by the kidneys; about 2% is excreted unchanged through the intestine.

Indications for use

Estrovagin is used in the postmenopausal period for pre- and postoperative therapy in women who are about to or have already undergone vaginal surgery.

For postmenopausal women, the drug is prescribed for hormone replacement therapy for atrophy of the mucous membrane of the lower parts of the urinary tract against the background of estrogen deficiency.

Estrovagin is also used for diagnostic purposes in women with atrophic changes in the epithelium of the cervix with unclear cytological results.

Drug interactions

• powerful inhibitors of microsomal oxidation (ritonavir, nelfinavir): significantly inhibit the metabolism of estriol;
• inducers of microsomal oxidation (rifampicin, phenytoin, rifabutin, carbamazepine, efavirenz, nevirapine, phenobarbital): increase estriol metabolism;
• thyroid hormones and folic acid: enhance the effect of Estrovagin;
• ethanol, general anesthetics, anxiolytics, narcotic analgesics, some antihypertensive agents: reduce the effect of Estrovagin;
• St. John's wort preparations: can increase the metabolism of estriol, as a result of which a decrease in its effectiveness is possible;
• hypoglycemic, diuretic and antihypertensive drugs, antidepressants, anticoagulants and male sex hormones: estriol weakens their effect;
• lipid-lowering drugs: estriol enhances their effect.
