Diferelin - action and therapeutic effects
Dipherelin is an analogue of gonadotropin releasing hormone (GnRH) produced by the hypothalamus. GnRH acts on the pituitary gland, which, in turn, produces tropic sex hormones, such as follicle-stimulating hormone, luteinizing hormone, testosterone, etc. And these tropic hormones regulate the functioning of the female and male genital organs, for example, the ovaries, uterus, testes, prostate gland. Diferelin reduces the production of tropic hormones of the pituitary gland, accordingly, reducing the activity of the ovaries and testes in the synthesis of sex hormones. Thus, therapeutic effects The drug is due to its effect on the level of production of the genital organs by the ovaries of women and the testicles of men.Since sex hormones influence the development and course of certain pathologies, the use of Diferelin, which reduces their production, is justified in complex therapy diseases caused by increased levels estrogen in women and testosterone in men. This effect Diferelina is called antigonadotropic and antitumor.
So, when using Diferelin, stimulation of the pituitary gland is observed during the first 2 - 3 weeks, but then, throughout the rest of the course of therapy, the drug suppresses the synthesis of follicle-stimulating and luteinizing hormones, and, accordingly, the production of both androgens and estrogens decreases. The maximum severity of the antiandrogenic effect is achieved at 3 weeks from the start of Diferelin use and persists throughout the rest of the course of treatment.
Due to the stimulating effect of Diferelin during the first 2 - 3 weeks of use, it is used to stimulate ovulation and transfer of a fertilized embryo in in vitro fertilization protocols.
Diferelin in the treatment of endometriosis, as a rule, causes amenorrhea (artificial menopause, absence of menstruation). However, after cessation of therapy, menstruation returns within a certain period of time (from 1 to 12 months), the specific duration of which depends on individual characteristics woman's body. Most often, the first ovulation occurs by the end of the second month, counting from the last injection of Diferelin, and menstruation begins, respectively, after 2.5 - 3 months.
If endometriosis recurs after one course of therapy with Diferelin, then after 6–12 months, if necessary, you can be treated again. However, when endometriosis recurs, treatment is usually not resorted to. repeat courses treatment with Diferelin, but use other drugs (for example, Buserelin, etc.) or cauterize the lesions during laparoscopic surgery.
Diferelin for premature puberty One dose is administered every 28 days. One dose for children weighing more than 20 kg is 3.75 - that is, one full bottle of lyophilisate. And one dose for children weighing less than 20 kg is only 1.875 mg, that is, half of one bottle of lyophilisate. The duration of therapy is determined by the doctor and depends on the speed of normalization of the condition.
Half the dosage for children weighing less than 20 kg is prepared in the following way: take the entire volume of the solvent and add it to the bottle with the lyophilisate. The entire volume of the lyophilisate is dissolved, but only half of the resulting suspension is drawn into the syringe. It is very simple to understand how much half is - divide the volume of the ampoule with the solvent by two. For example, in a sealed ampoule there are 2 ml of solvent, which means half is 1 ml. That is, all 2 ml of solvent is added to the bottle with the lyophilisate, mixed well, but only 1 ml of the finished suspension is taken into the syringe for injection.
Diferelin for female infertility administer one whole bottle (3.75 mg each) on the second day of the menstrual cycle. Treatment is continued for a period of time determined by the doctor.
Diferelin for uterine fibroids is administered for the first time during the first five days of the next menstrual cycle. This means that after the start of the next menstruation, it is necessary to administer the first dosage of Diferelin within five days. Subsequently, the drug is administered every 4 weeks (28 days) for 3 months. Each time, one full bottle of Diferelin is administered, that is, 3.75 mg of the active substance.
During treatment uterine fibroids Diferelin usually causes amenorrhea (cessation of menstruation) in a woman. This has a positive effect on general condition women, since she does not experience blood loss during bleeding and heavy menstruation. After stopping the use of Diferelin, menstruation is restored within several months. During the entire period of use of the drug, it is necessary to regularly perform ultrasound of the pelvic organs, monitoring the rate of decrease in the size of the uterus and fibroids. If the uterus decreases in size faster than fibroids, it is urgent to perform an operation, since this situation is fraught with the development of sepsis.
Diferelin 11.25 – instructions for use
This variety of Diferelin is also a depot form, and a single administration of a bottle of 11.25 mg of the active substance provides it therapeutic activity during three months. That is, for treatment, Diferelin 11.25 is administered one bottle once every three months.For prostate cancer in men and endometriosis in women, Diferelin is administered in one bottle every three months. The duration of treatment for prostate cancer depends on the rate of improvement and involution of the formation. And the duration of treatment for endometriosis is 3–6 months, since the drug is not recommended for use for more than six months in a row.
The first injection of Diferelin in men can be made at any time, and in women with endometriosis - only during the first five days of the next menstrual cycle.
Overdose and interaction with other drugs
No interactions of Diferelin with other drugs or cases of overdose have been identified.The drug does not affect the ability to control machinery, so you can drive a car during the course of therapy.
Use during pregnancy
Diferelin is contraindicated for use during pregnancy. This means that if a woman is already pregnant, it cannot be used.However, the drug is used to stimulate ovulation, and many women became pregnant after several injections, but without knowing it, they continued to use Diferelin. Such cases made it possible to accurately establish that the drug does not have negative impact on the fetus, does not provoke the development of congenital deformities and does not increase the risk of miscarriage. This suggests that Diferelin is not dangerous to the fetus, but further study of its properties is necessary.
After Diferelin - general condition
Diferelin reduces the production of sex hormones in men and women and, in fact, puts them in a state of artificial castration. That is, under the influence of Diferelin, a hormonal background is created in a man, like a eunuch (castrato), and in a woman, like during menopause or both ovaries have been removed. Naturally, entry and exit from this state accompanied by neuro-vegetative, endocrine-metabolic and psychological disorders and numerous complaints.After completing the course of using Diferelin, the hormonal balance is gradually restored, but until the balance of hormones is normalized again, a person may experience headaches, irritability, fatigue, hot flashes, sweating, changes in body weight, increased body temperature, depression and other complaints.
The condition usually returns completely to normal within a month and a half after the last injection ends. That is, we can expect normalization of the condition 4.5 months after the last injection of Diferelin 11.25 and 2.5 months after Diferelin 3.75. During this period, men and women fully recover sexual and reproductive function and libido is normalized.
Menstruation and pregnancy after Diferelin
Ovarian functions are usually completely restored approximately 1.5 months after the end of the last Diferelin injection administered for the treatment of endometriosis. This means that menstruation should be expected approximately 4.5 months after the last administration of Dipherelin 11.25 and 2.5 months after Dipherelin 3.75. It is during this period that the first menstruation after Diferelin usually occurs, which can be different. However, menstruation is usually painless or slightly painful and scanty. By the second menstrual cycle, menstruation is taken normal character. However, the first menstruation, which began 4 to 6 months after the end of the last injection of Diferelin, is also considered normal.Since the first ovulation usually occurs a month after the last injection of Diferelin ends, if you do not want to get pregnant, you should start using contraceptive methods in advance. It is recommended to start using contraceptive methods from the 15th day after the end of the last Diferelin injection.
When using Diferelin 0.1 in short and long IVF protocols, menstruation is usually delayed by several days - from 5 to 15. In some cases, menstruation stops altogether, and in this case the doctor determines the tactics of further stimulation solely on the basis of test results.
