2. Rarely: blurred vision, diplopia, flashes in front of the eyes, sensitive eyes to light, decreased vision, yellowing of the skin and sclera.

Contraindications and precautions

Unexplained irregular vaginal bleeding, uterine fibroids, ovarian cysts, liver damage, depression, thrombophlebitis, etc. are prohibited.

Precautions

1. Animal experiments have proven that this product can cause teratogenicity. Basal body temperature should be measured daily during medication to monitor ovulation and conception of the patient, and the drug should be discontinued as soon as the conception is achieved.

2. Polycystic ovary syndrome should be used with caution.

3 The following determinations are made during medication as needed:

Ovulation promoting hormone (FSH) and luteinizing hormone (LH);

Long-term drug users measure the content of 24-dehydrocholesterol in the plasma to find out whether the drug has an effect on cholesterol synthesis;

the content of corticosteroids in plasma;

serum thyroxine content;

Content of sex hormone binding globulin;

Sodium sulfobromophthalate (BSP) liver function test;

Thyroxine-binding globulin content (may increase).

4 During the medication, pay attention to check: the size of the ovary must be correctly estimated before the start of each course; basal body temperature should be measured every day, and the levels of estrogen and serum progesterone should be measured if necessary; the amount of progesterone in the urine should be measured to determine whether ovulation; For liver function, those who have been treated for more than 1 year must undergo fundus and slit lamp examinations; if visual impairment occurs during the medication, the drug should be stopped immediately and the corresponding examination should be performed.

[Pharmacology and Toxicology]

Antihormonal drugs. The mechanism by which this product stimulates ovulation is not fully understood. Because this product has both weak stimulus and strong antagonistic effects on estrogen, stimulation of ovulation may be in the hypothalamus site. Antagonism is dominant first, and it will interfere with the negative effects of endogenous estrogen by competitively occupying the hypothalamic estrogen receptor. The feedback promoted the secretion of luteinizing hormone and follicle-stimulating hormone, followed by stimulation of follicle growth. After the follicle matured, the release of estrogen increased. Positive feedback stimulated the release of gonadotropin before ovulation reached its peak, so ovulation and treatment Male infertility may be associated with elevated FSH and LH and the promotion of spermatogenesis.

Pharmacokinetics

After oral administration, it is absorbed through the intestine and enters the blood circulation of the liver. T1 / 2 is generally 5 to 7 days. This product is metabolized in the liver. It enters the intestinal tract with bile, and is then eliminated from feces. Part of it is reabsorbed through the hepato-enteric circulation. Half excreted from feces within 5 days. It can still be detected in feces within 6 weeks.

[Foreign name] Clomiphene, ClomifeneCltrate

[Indications] Has strong anti-estrogen effect and weak estrogen activity. Low doses can promote the secretion of gonadotropins in the anterior pituitary gland to induce ovulation; high doses significantly inhibit the release of pituitary gonadotropins, and have a role in promoting spermatogenesis in men and are effective for oligozoospermia.

[Dosage and Administration] Oral: 50 mg once daily for menstrual period for 5 days, and 50 mg once daily for menstrual period for 5 days. Generally, ovulation occurs about 7 days after taking the medicine, and menstruation occurs naturally after 3 weeks. Consecutive service for 3 cycles is 1 course of treatment. Amenorrhea patients can first use progesterone (20mg intramuscularly once a day) or artificial cycle (diethylstilbestrol 1mg once daily for 20 days, and then daily progesterone 10mg intramuscularly, once daily) Take this product on the 5th day of withdrawal bleeding. The daily dose should not exceed 100mg. For male infertility, 25mg once daily, even for 25 days as a course of treatment. After 5 days of drug withdrawal, repeat the administration until the sperm count reaches the normal standard. Generally, the effect is good for 3-12 months.

[Precautions] 1. Disappear after withdrawal. 2. In the treatment of male infertility, semen examination, endocrine examination, and testicular biopsy must be performed before taking the medicine to determine that the cause of infertility is mainly due to the decrease in sperm count; regular check of semen routine, FSH and testosterone levels during medication; Effective from 2 to 3 months. The principle of medication is low dose and long course of treatment. It should be noted that high dose will inhibit spermatogenesis. 5. Excessive dosage can cause ovarian hypertrophy. 6. Blurred vision and flickering blind spots are dose-dependent, and withdrawal can be reversed. 7. Visual abnormalities should be used as contraindications to the use of this product.

Clomiphene has many side effects, such as headache, abdominal pain, gastrointestinal symptoms (nausea, vomiting, bloating), etc., and may have enlarged ovaries, cystic changes, and sometimes unruptured follicular luteinization. Large doses and long-term cases may have multiple pregnancies. In addition, cervical mucus becomes sticky after administration, which prevents sperm from passing and reduces the pregnancy rate. Sometimes there are even side effects such as ascites, pleural effusion, or pleural effusion. In severe cases, it can even cause death. Medically it is called "ovary hyperstimulation". Therefore, clomiphene ovulation-promoting treatment, patients should not be used without permission, must be taken under the guidance of a physician. During the medication, a pelvic examination should be performed to observe the changes in the ovaries. Those who have enlarged ovaries must stop the medication.
