Characteristic:

Drug for hormone replacement therapy with normal (2/10) and low-dose (1/10) content as the estrogen component - estradiol, as the progestin component - dydrogesterone.

Pharmacokinetics:

After oral administration, micronized estradiol is readily absorbed. It is metabolized in the liver to estrone, and estrone sulfate, which is also subject to hepatic biotransformation. Glucuronides of estrone and estradiol are derived mainly from the urine.

Didrogesteron after ingestion is rapidly absorbed from the gastrointestinal tract. Metabolized completely. The major metabolite - 20 digidrodidrogesteron present in the urine mainly as glucuronic acid conjugate. Complete removal of dydrogesterone occurs after 72 hours.

Description of the pharmacological actions:

Estradiol - estrogen, which is part of the preparation Femoston identical to endogenous human estradiol. Estradiol restores deficit of estrogen in the female body after menopause and provide effective treatment for psycho-emotional and vegetative menopausal symptoms, "tides", increased sweating, sleep disturbances, increased nervous irritability, dizziness, headache, involution of the skin and mucous membranes, especially the mucous membranes of the genitourinary system (dryness and irritation of the mucous membrane of the vagina, pain during sexual intercourse). Hormone replacement therapy (HRT) drug Femoston prevents bone loss in post-menopausal, caused by estrogen deficiency. Admission Femoston preparation leads to a change in the lipid profile in the direction of reducing total cholesterol and LDL and increase HDL.

Dydrogesterone is a progestogen that is effective when taken orally, which fully meets the offensive phase of the secretion of the endometrium, thereby reducing the risk of endometrial hyperplasia and / or carcinogenesis, against the backdrop of rising estrogen. Dydrogesterone has no estrogenic, androgenic, or anabolic glucocorticosteroid activity.

The combination of 1 mg estradiol dydrogesterone is a modern low-dose HRT regimen.

Drug Interactions:

Drugs that are inducers of microsomal liver enzymes (barbiturates, phenytoin, rifampin, rifabutin, carbamazepine) may reduce estrogenic effects Femoston drug. Ritonavir and nelfinavir, although known as inhibitors of microsomal metabolism, can play the role of inductors while admission to steroid hormones. Preparations on the basis of herbs containing St. John's wort, can stimulate the exchange of estrogens and progestogens.

Dydrogesterone Interactions with other medicines are not known.

The patient should inform the doctor about the medications that she takes a moment or took up appointment Femoston drug.

Special instructions:

Before the appointment or renewal of HRT need to collect a complete medical and family history and to hold general and gynecological examination in order to identify possible contraindications and conditions requiring precautions. At the time of treatment is recommended to periodically examine women (frequency and nature of the research is determined individually). In addition, it is advisable to carry out a study of breast and / or a mammogram in line with accepted standards, taking into account clinical indications. The use of estrogen can influence the results of these laboratory tests: determination of glucose tolerance study thyroid and liver.

Generally recognized risk factors for thrombosis and thromboembolism in patients receiving HRT are thromboembolic events in history, severe obesity (body mass index over 30 kg / m2) and systemic lupus erythematosus. Regarding the role of varicose veins in the development of thromboembolic events is not generally accepted opinion.

The risk of developing deep vein thrombosis may be temporarily increased with prolonged immobilization, major trauma or surgery. In cases where long-term immobilization is needed after surgery, should be considered a temporary cessation of HRT for 4-6 weeks prior to surgery.

When deciding on hormone therapy in patients with recurrent deep vein thrombosis or thromboembolism treated with anticoagulants, it is necessary to carefully evaluate the benefits and risks of HRT.

If thrombosis developed after initiation of hormone replacement therapy, the drug should be discontinued. The patient should be informed of the need to see a doctor in the event of the following symptoms: painful swelling of the lower limbs, sudden loss of consciousness, dyspnea, impaired vision.

There are data that show a slight increase in the detection rate of breast cancer in women, long-term (over 10 years) treated with HRT. The probability of diagnosing breast cancer increases with duration of treatment and returned to normal after 5 years after stopping HRT.

Patients previously treated with HRT with estrogen drugs only need to be very carefully examined before treatment to identify a possible hyperstimulation of the endometrium. Breakthrough uterine bleeding and mild expressed menstrualnopodobnye bleeding may occur during the first months of drug treatment. If, despite dose adjustments like bleeding does not stop, the drug should be withdrawn to determine the cause of bleeding. If the bleeding recurs after a period of amenorrhea or persists after discontinuation of treatment should be to establish its etiology. This may require a biopsy of the endometrium.
