Iprozhin

The drug Iprozhin cannot be used for the purpose of contraception.
The drug should not be taken with food, since food intake increases the bioavailability of progesterone.

The use of the drug Iprozhin after the first trimester of pregnancy can cause the development of cholestasis. The drug should be taken with caution in patients with diseases and conditions that may be aggravated by fluid retention (arterial hypertension, cardiovascular disease, chronic renal failure, epilepsy, migraine, bronchial asthma); in patients with diabetes mellitus; liver dysfunction of mild to moderate severity; photosensitivity.

Patients with concomitant cardiovascular diseases or a history of them should be periodically observed by a doctor.

Patients with a history of depression should be monitored, and if severe depression develops, the drug should be discontinued.

Iprozhin contains soy lecithin, which can cause hypersensitivity reactions (urticaria and anaphylactic shock).

During long-term treatment with progesterone, regular medical examinations (including liver function tests) are necessary; Treatment should be discontinued if abnormal liver function tests or cholestatic jaundice occur.

When using progesterone, it is possible to reduce glucose tolerance and increase the need for insulin and other hypoglycemic drugs in patients with diabetes mellitus.

If amenorrhea occurs during treatment, pregnancy must be excluded.

If the course of treatment begins too early in the menstrual cycle, especially before the 15th day of the cycle, shortening of the cycle and/or acyclic bleeding is possible. In case of acyclic bleeding, the drug should not be used until the cause is determined, including a histological examination of the endometrium.

More than 50% of spontaneous abortions in early pregnancy are caused by genetic disorders. In addition, the cause of spontaneous abortions in early pregnancy can be infectious processes and mechanical damage. The use of the drug Iprozhin in these cases can only lead to a delay in rejection and evacuation of a non-viable fertilized egg. The use of the drug Iprozhin to prevent habitual abortion is justified only in cases of progesterone deficiency.

When carrying out HRT with estrogen-containing drugs during perimenopause, it is recommended to use the drug Iprozhin for at least 12 days of the menstrual cycle.

With a continuous HRT regimen in postmenopause, it is recommended to use the drug from the first day of taking estrogen-containing drugs.

When carrying out HRT, the risk of developing venous thromboembolism (deep vein thrombosis or pulmonary embolism), the risk of ischemic stroke, and coronary heart disease increases.

Due to the risk of developing thromboembolic complications, you should stop using the drug if: visual disturbances such as vision loss, exophthalmos, double vision, vascular lesions of the retina: migraine; venous thromboembolism or thrombotic complications, regardless of their location.

If there is a history of thrombophlebitis, the patient should be closely monitored. When using the drug Iprozhin with estrogen-containing drugs, you must refer to the instructions for their use regarding the risks of venous thromboembolism. Results from the Women Health Initiative Study (WHI) indicate a small increase in the risk of breast cancer over a long period of more than 5 years. combined use of estrogen-containing drugs with gestagens. Regarding the use of estrogen-containing drugs in combination with progesterone as part of HRT, there is no evidence of an increased risk of breast cancer.

The WHI study also found an increased risk of dementia when starting HRT after age 65 years.

Before starting HRT and regularly during it, a woman should be examined to identify contraindications to her behavior. If clinically indicated, a breast examination and gynecological examination should be performed.

If there is a history of chloasma or a tendency to develop it, patients are advised to avoid UV irradiation.

The use of progesterone may affect the results of some laboratory tests, including liver and thyroid function tests; coagulation parameters; pregnanediol concentration.

pharmachologic effect

Iprozhin is a gestagen, a hormone of the corpus luteum. By binding to receptors on the surface of cells of target organs, it penetrates into the nucleus where, activating DNA, it stimulates RNA synthesis.

Promotes the transition of the uterine mucosa from the proliferation phase caused by follicular hormone to the secretory phase, and after fertilization - to the state necessary for the development of a fertilized egg.

Reduces the excitability and contractility of the muscles of the uterus and fallopian tubes, stimulates the development of the end elements of the mammary gland.

By stimulating protein lipase, it increases fat reserves, increases glucose utilization, increasing the concentration of basal and stimulated insulin, promotes the accumulation of glycogen in the liver, increases the production of aldosterone; in small doses it accelerates, and in large doses it suppresses the production of gonadotropic hormones of the pituitary gland; reduces azotemia, increases nitrogen excretion in urine. Activates the growth of the secretory section of the acini of the mammary glands and induces lactation. Promotes the development of normal endometrium.

Pharmacokinetics

When taken orally, it is well absorbed from the gastrointestinal tract, the time to reach Cmax is 1-3 hours. After taking 200 mg, the concentration of progesterone in plasma increases from 0.13 ng/ml to 4.25 ng/ml after 1 hour and is 11.75 ng/ml after 2 hours, 8.37 ng/ml - after 3 hours, 2 ng/ml - after 6 hours, 1.64 ng/ml - after 8 hours.

When administered intravaginally, it is rapidly absorbed, a high concentration of progesterone in plasma is observed after 1 hour. The time to reach Cmax is 2-6 hours. When administered 100 mg 2 times a day, the average concentration is 9.7 mg/ml for 24 hours. When administered more than 200 mg progesterone concentration corresponds to the first trimester of pregnancy. Communication with plasma proteins - 90%.

Metabolized in the liver with the participation of the CYP2C19 enzyme system. The main metabolites are 20-alpha-hydroxy-delta-4-alpha-pregnanolone and 5-alpha-dihydroprogesterone. Excreted by the kidneys - 50-60%.
