Neoplasms of malignant nature currently occupy one of the leading places in terms of mortality among the population almost all over the world. The longer a person postpones a visit to the doctor, the harder and longer the path to recovery. It is in this direction of medicine that the words that lost time is equivalent to life would be the most correct.

In the arsenal of modern pharmacology, there is currently a mass of medicines designed to fight against malignant tumors that affect the most diverse organs of the human body. For the treatment of hormone-dependent malignant tumors, medicines are widely used today - analogues of the hormones of the hypothalamus (the brain department responsible for the functioning of the neuroendocrine system). One of these drugs is “Buserelin-Long”.Health

Composition and forms of release

The main active ingredient of the drug is buserelin acetate. Among the auxiliary substances, the copolymers of lactic and glycolic acids, polysorbate-80, carmellose sodium, and d-mannitol are included in the drug.

Today, the pharmacy network of the Russian Federation offers its consumers this anticancer drug in two forms of release. One is a nasal spray (for insertion through the nose), the second is a powder composition for preparing a solution, which is then injected intramuscularly. Actually, the second form (solution) is also called “Buserelin-Long”. Instructions for use contains detailed information on the principle of pharmacological effects on the human body.

Usually in a blister box enclosed in a cardboard box, there is a bottle of medication, a vial with a solvent, a disposable syringe (5 ml), 2 sterile needles (for solvent and for injection), scarifier or opener for opening the ampoule and 2 alcohol napkins.


At the initial stage of the use of this drug, there is a process of enhanced release of gonadotropins (hormones, the main function of which is to regulate the functions of the sex glands). During this period, an increase in the amount of sex hormones may be observed briefly in patients with blood.

After 12-14 days, the action of the drug causes a blockage of the gonadotropic function of the pituitary gland, which is characterized by the termination of the secretion of hormones that stimulate the maturation of follicles and the production of lutein. The result is inhibition of the synthesis of sex hormones in the ovaries, and, as a result, the plasma level of estradiol (the main female hormone) drops to the levels typical for the post menopausal period. A condition called by medical workers “drug pseudomenopause” is developing.

If this drug is used for a long enough period of time for the treatment of prostate cancer, the result may be a significant decrease in the blood plasma concentration of testosterone (the main male hormone). In the medical environment, this condition is called "pharmacological castration."

Taking medication on the basis of buserelin in the period preceding surgical intervention for endometriosis will help reduce the size of the lesions of the pathology, reduce their blood supply, attenuation of inflammatory processes. In the postoperative period, the influence of the drug will reduce the process of formation of adhesions and reduce the frequency of relapses.

Patients need to be aware that the effect of the drug is reversible. After discontinuation of the drug, the level of male and female sex hormones in the blood will gradually return to normal.

Who is indicated for use?

"Buserelin-Long" instruction to the drug recommends taking with hormone-dependent pathological processes of the human reproductive system, caused by absolute or relative hyperestrogenism. Sufficient grounds for the use of this drug can be considered in women diseases such as uterine fibroids, endometriosis, endometrial hyperplastic changes.

In addition, the drug is prescribed for malignant tumors of the prostate gland (hormone-dependent form, stage 3 and 4), for breast cancer (if the menstrual cycle is preserved, and progesterone and estradiol receptors are available).

It is also a drug widely used in in vitro fertilization procedures (IVF). The main function of the drug in this case is to suppress the effects of the woman’s own hormonal system. Thus, an artificial controlled hormonal system is being “formed”, which allows an already fertilized egg to be implanted in a woman. In the treatment of infertility, boserelin-containing medications stimulate the process of ovulation.

Contraindications for taking "Buserelin-Long"

Careful and attentive to their well-being should be people who have a history of obstruction of the urinary tract. Patients whose malignant prostate cancer has metastasized to the spine should also behave. At the initial stage of treatment in such patients, the likelihood of an exacerbation of the underlying disease increases.

The scheme of using a medical product in the treatment of infertility with the use of IVF techniques looks somewhat different. The first injection of “Buserelin-Long” is made either on the second day of the menstrual cycle (beginning of the follicular phase), or in the period from the 21st to the 24th day (middle of the luteal phase). After 12–15 days after the injection, the amount of estrogen contained in the serum will drop to half of the initial (blocking the pituitary function). Further, if the patient does not have cysts on the ovaries (ultrasound examinations), and the thickness of the endometrial layer does not exceed 5 mm, one can proceed to stimulate superovulation with the help of gonadotropic hormones. These activities are carried out under ultrasound monitoring with mandatory monitoring of estradiol levels. The dose of "Buserelin-Long" can be adjusted in one direction or another.

Special recommendations

Before starting a course of therapy with the use of the drug "Buserelin-Long," it will not be superfluous to familiarize yourself with some of the special recommendations that are contained in the instructions for use of the drug.
