    АТХ:

    G.03.C.A.03   Estradiol

    Pharmacodynamics:

    Estrogen. Follicular hormone, necessary for the development of the female body and the reproductive system. Exogenous estradiol has the same physiological effect as natural hormones: it stimulates the development of the uterus, the fallopian tubes, the development of secondary sexual characteristics in their underdevelopment, causes proliferative changes in the endometrium, increases the excitability of the uterus, and suppresses lactation in large doses. Estradiol regulates nitrogen metabolism, reduces the level of lipids and cholesterol in the blood, has a weak anabolic effect. Helps maintain a balance between osteoblasts and osteoclasts, reduces bone resorption and promotes its formation.

    Pharmacokinetics:

    After oral administration, it is absorbed from the digestive tract. It is affected by the effect of the first passage through the liver.Metabolized to less active metabolites - estriol and estrone. Metabolites are excreted by the kidneys, a small part through the intestine.

    Indications:

    Amenorrhoea primary and secondary; hypoplasia of the reproductive apparatus and secondary sexual characteristics; hormone replacement therapy observed in the period of natural or surgically induced menopause (including vasomotor disorders, hot flushes, increased sweating, sleep disorders, atrophic processes from the vagina and lower urinary tract), caused by a deficiency in the production of endogenous estrogens; prevention of recurrent infectious-inflammatory diseases of the vagina and lower urinary tract; prevention and treatment of postmenopausal osteoporosis; as a means of stimulating hemopoiesis in men with acute radiation damage.

    In the initial period of treatment, patients with diabetes require careful monitoring because of a possible decrease in glucose tolerance.

    Pregnancy and lactation:

    Action category for the fetus by FDA - X.

    Contraindicated in pregnancy, including presumed (estrogens may have embryotoxic effect). Studies have shown the relationship of congenital malformations with the use of certain estrogens during pregnancy.

    For the duration of treatment, breastfeeding should be stopped (estrogens enter breast milk).

    Dosing and Administration:

    The doses and duration of therapy are set individually.

    Inside. Primary and secondary estrogenic insufficiency - 2 mg 1 time per day, daily without interruptions. Treatment of women with a deleted uterus or postmenopausal women can start any day; with the saved menstrual cycle, the first tablet is taken on the 5th day of the menstrual cycle. Duration of treatment is 6 months, after which a survey is conducted to determine whether it is advisable to continue estrogen replacement therapy.

    Locally. The gel is applied once a day to the skin on the lower part of the anterior wall of the abdomen, or alternately to the right or left buttock. The initial dose is 1 g of gel (1 mg of estradiol).The average dose is 0.5-1.5 g of gel per day. Application area is equal to 1-2 palms. The patch is attached once a week. Treatment is carried out continuously or 3-week courses with a break of 1 week. In the presence of the uterus simultaneously appoint progesterone every month for 10-12 days.

    Intranasally 1 time per day. The daily dose depends on individual characteristics and, as a rule, varies from 150 to 600 mcg, the initial dose is 300 mcg per day, during therapy, the minimum effective dose should be selected; depending on the therapeutic effect of treatment, the dose is reduced or increased.

    Intramuscularly 0.1% solution in oil 1 ml every 1 to 3 days.

    Side effects:

    From the side nervous system and sense organs: dizziness, headache, migraine, depression, chorea, visual impairment (changes in curvature of the cornea), discomfort when wearing contact lenses.

    From the side cardiovascular system and blood (hematopoiesis, hemostasis): increased blood pressure, thromboembolism.

    From the side organs of the digestive tract: nausea, vomiting (mainly central genesis when using high doses), epigastric pain, flatulence, diarrhea, anorexia, cholestatic jaundice, cholelithiasis, hepatitis, pancreatitis, intestinal and biliary colic.

    From the side genitourinary system: in women hemorrhages of the "breakthrough", uterine hemorrhages of unclear etiology, change in the character of uterine bleeding and spotting, metrorrhagia (a sign of overdose of estradiol), premenstrual syndrome, amenorrhea, dysmenorrhea, increased size of fibroids or uterine leiomyoma, changes in cervical secretion, changes in the nature of vaginal discharge, vaginal candidiasis, endometrial hyperplasia (when administered without progestogen), endometrial carcinoma (in menopause in women with an intact uterus), symptoms of cystitis (without bacterial charge zheniya); with prolonged use - sclerosis of the ovaries; soreness, sensitivity and increase in breast size, increased libido; in men - tenderness and sensitivity of the mammary glands, gynecomastia, decreased libido.

    From the side skin integument: chloasma or melasma, contact dermatitis, hemorrhagic rash, erythema nodosum, erythema multiforme, alopecia, hirsutism, itching and hyperemia of the skin (on the spot of patch application-TDTS).

    Other: change in body weight, decreased tolerance to carbohydrates, worsening of porphyria, spasms of calf muscles; at long application - infringement of an exchange of sodium, calcium and water with formation of peripheric edemas.

    Overdose:

    Symptoms: nausea, vomiting, in some cases - metrorrhagia.

    Treatment: maintenance of vital functions (against drug withdrawal), symptomatic therapy.

    Interaction:

    Estradiol reduces the activity of diuretics, anticoagulants, hypotensive and hypoglycemic agents. Reduces glucose tolerance (may require correction of the dosage regimen of hypoglycemic agents). Estradiol increases the effectiveness of lipid-lowering drugs.

    Inducers of microsomal liver enzymes, for example, some anticonvulsant and antimicrobial agents (including hydantoins, barbiturates, primidon, carbamazepine, rifampicin), can accelerate the metabolism of estradiol, increase the clearance of sex hormones and reduce clinical effectiveness.

    Folic acid and thyroid drugs strengthen the action of estradiol. Significant consumption of alcohol during treatment can lead to increased levels of circulating estradiol.

    Special instructions:

    Before the beginning of the application it is necessary to conduct a complete general medical and gynecological examination,including examination of the organs of the abdominal cavity and small pelvis, mammary glands, measurement of blood pressure, cytological analysis of the endometrium. It is necessary to exclude pregnancy. With prolonged therapy, a similar examination should be performed every 6-12 months.

    4-6 weeks before the planned surgical intervention and during a period of prolonged immobilization, it is recommended to discontinue treatment to avoid thrombosis.

    The drug should be discontinued immediately in the following cases: deep vein thrombosis, thromboembolic disease, a significant increase in blood pressure, the appearance of jaundice, the appearance of migraine headache, sudden visual impairment.

    During hormone replacement therapy, patients with hypertension should regularly monitor blood pressure.

    The change in the level of estrogen in the blood can affect the performance of some endocrine and liver functions.

    Estrogens can cause fluid retention in the body, so patients with impaired cardiac or renal function require careful monitoring.

    It is necessary to inform the attending physician about the simultaneous administration of barbiturates, phenylbutazone, hydantoins, rifampicin,the occurrence of irregular bleeding or unusually heavy bleeding in the period between use of the drug, discomfort in the epigastric region.

    In the event of irregular uterine bleeding during the administration of the drug, a cytological analysis of the endometrium should be performed.

    During treatment, it should be borne in mind that prolonged use of only estrogens in the climacteric period can lead to endometrial hyperplasia and increases the risk of developing endometrial cancer. To reduce the risk of developing endometrial cancer, an additional progestogen should be taken (usually for 10-12 days per month), which leads to a transition of the mucous membrane of the uterus to the secretory phase, with its rejection and subsequent menstrual bleeding after discontinuing progestogen administration. When irregular menstrual flow (in women with an intact uterus) appears against the background of estradiol treatment, diagnostic scraping should be performed to exclude the malignant neoplasm of the uterus.

    In postmenopausal women who have been on hormonal replacement therapy for a long time, the risk of breast cancer increases.If the duration of treatment is more than 5 years, it is necessary to carefully weigh the positive effects of treatment with adverse effects.

    In patients who are on long-term treatment, regular examination of the mammary glands is necessary, including one should teach them regular self-examination. Special caution should be exercised when administering estrogens to women who have or have had nodular or fibrocystic breast changes in the past. In such cases careful monitoring and regular mammography should be performed.

    For women taking estrogen preparations in the menopausal period, there is an increased risk of cholelithiasis (estrogens increase the lithogenicity of bile).

    The drug is not a contraceptive and does not restore the ability to fertilize.

    Do not put the band-aid on the area of ​​the mammary glands or waist. If the patch is applied correctly, then you can take a bath or shower, but you need to take into account that in hot water the patch can get unstuck.

    Transdermal systems with estradiol are prescribed only to women.

    You should avoid getting the gel on the mammary glands and mucous membranes of the vulva and vagina.
