Pharmacological properties
Pharmacodynamics
The active ingredient of Clostilbegit is clomiphene - an antiestrogenic agent of a non-steroidal structure.
The mechanism of its action is explained by the ability to specifically bind to estrogen receptors of the pituitary gland and ovaries. In patients with a low estrogen content in the body, the drug exhibits a moderate estrogenic effect, in patients with a high estrogen content - an antiestrogenic effect.
When used in small doses, it enhances the secretion of gonadotropins (follicle-stimulating hormone, luteinizing hormone and prolactin), stimulates ovulation. In high doses, clomiphene inhibits the secretion of gonadotropins.
Clostilbegit does not possess androgenic and gestagenic activity.
Pharmacokinetics
After oral administration, clomiphene is well absorbed from the gastrointestinal tract.
Metabolized in the liver. Undergoes enterohepatic recirculation.
It is excreted mainly in the bile. The half-life is 5-7 days.

Instructions for the use of Klostilbegit: method and dosage
In the treatment of infertility, the dose and duration of the treatment course are determined by the sensitivity to the action of Klostilbegit ovaries.
It is recommended to start treatment for women with a regular menstrual cycle on the fifth day of the cycle or on the third day of the cycle if the follicular phase lasts less than 12 days or early ovulation. With amenorrhea, therapy can be started any day.
First, Klostilbegit tablets are used according to the following scheme: for 5 days, 50 mg per day with simultaneous monitoring of the ovarian reaction using laboratory and clinical studies. As a rule, ovulation occurs between 11 and 15 days of the cycle.
If therapy does not lead to ovulation, the drug is used according to the second scheme: for 5 days, starting from the 5th day of the next cycle, take 100 mg of Klostilbegit per day. If ovulation does not occur at this time, the same scheme must be repeated again. With ongoing anovulation, you should take a three-month break in taking the drug, and then repeat the therapy within the next 3 months. If the repeated course is ineffective, further use of Klostilbegit is not effective. A maximum of 750 mg of the drug can be taken during each course.
The initial daily dose of the drug for polycystic ovary syndrome is 50 mg (due to the tendency to hyperstimulation).
With post-contraceptive amenorrhea, Klostilbegit is taken daily at 50 mg. In most cases, the five-day course of the first treatment regimen described is successful.
In accordance with the indications for men, the drug is prescribed 1-2 times a day, 50 mg. The duration of therapy is 6 weeks (under systematic sperm analysis).
Side effects
During the use of Clostilbegit, the following side effects may develop (> 1% - often; <1% - rarely):
- Endocrine system: dysmenorrhea, breast induration, pathological uterine bleeding, an increase in the size of the ovary (including cystic); rarely - soreness in the area of the mammary glands. During therapy, the likelihood of endometriosis, ectopic pregnancy, multiple pregnancy, and the growth of existing uterine fibroids increases. Cystic enlargement of the ovaries is also possible, especially with Stein-Leventhal syndrome (the size of the ovaries can reach 4-8 cm). In this case, you need to monitor the body temperature and, as soon as it becomes biphasic, interrupt therapy;
- Central nervous system: headache, drowsiness, dizziness; rarely - slowing down of motor and mental reactions, depression, hyperexcitability, insomnia;
- Digestive system: vomiting, nausea; rarely - acute abdominal syndrome, flatulence, gastralgia, diarrhea, increased appetite;
- Reproductive system: vaginal dryness, pain in the lower abdomen;
- Urinary system: polyuria, increased urination;
- Sense organs: visual impairment (including blurred contours, double vision, impaired perception of light, photophobia);
- Metabolism: rarely - decrease or increase in body weight;
- Allergic reactions: rarely - allergic dermatitis, rash, vasomotor disorders, urticaria;
- Dermatological reactions: rarely - alopecia;
- Others: a feeling of rush of blood to the face, accompanied by a feeling of heat (disappears after the end of therapy).
Overdose
An overdose of clomiphene is usually manifested by the following symptoms: a feeling of flushed face, nausea, vomiting, visual disturbances (flashes, decreased visual acuity, scotoma), vasomotor reactions, pain in the abdomen and pelvic organs, enlarged ovaries.
Conducting symptomatic and supportive therapy is shown. There is no information available on the effectiveness of dialysis to eliminate clomiphene.
special instructions
Before starting therapy, it is recommended to conduct a study of liver function, as well as a thorough gynecological examination. Treatment should be started when the total content of gonadotropin in the urine is below the lower limit of normal or normal, the functions of the adrenal glands and the thyroid gland are normal, and the state of the ovaries is normal on palpation.
In the absence of ovulation, before starting the application of Klostilbegit, all other possible forms of infertility must be cured or eliminated.
With an increase in the ovaries during treatment or the occurrence of cystic changes, the drug should be interrupted until the size of the ovaries returns to normal. In the future, therapy can be resumed, but at the same time, the dose of Klostilbegit can be reduced or the duration of the course can be shortened.
During the use of Clostilbegit, constant supervision of a gynecologist is necessary, including control of ovarian function, vaginal examinations, observation of the "pupil" phenomenon. In many cases, it is difficult to determine the moment of ovulation, and corpus luteum insufficiency is also quite often observed. Therefore, it is recommended to carry out progesterone prophylactic therapy after conception.
The drug increases the likelihood of developing multiple pregnancies.
Each tablet of Clostilbegit contains 100 mg of lactose, so the drug should not be taken by patients with lactase deficiency, galactose intolerance or glucose malabsorption.
