Product group

Hormonal drugs

Antiprogestogen drug Drug that increases the tone and contractile activity of the myometrium

Release forms

  • 3 - blisters (1) - packs of cardboard.

Description of the dosage form

  • Tablets light yellow, biconvex, with identification code "167B" on one side.

pharmachologic effect

Synthetic steroid antiprogestogen. Blocks the action of progesterone at the level of progestogen receptors. It does not have gestagenic activity, antagonism with GCS is noted (due to competition at the level of communication with receptors). Depending on the phase menstrual cycle causes an increase in the contractility of the myometrium, stimulating the release of interleukin-8 in choriodecidual cells, increasing the sensitivity of the myometrium to prostaglandins (to enhance the effect, it is used in combination with a synthetic analogue of prostaglandin), resulting in desquamation of the decidua and excretion of the fetal egg. It causes inhibition of ovulation, changes in the endometrium and prevents the implantation of a fertilized egg. Sex hormones, especially progesterone, play a key role in the pathogenesis of uterine leiomyoma. Blockade of progesterone receptors can contribute both to inhibition of tumor growth and to a decrease in the size of myomatous nodes and uterus.

pharmachologic effect

The pharmacological action of Mifegin is due to its ability to block the action of the hormone progesterone at the receptor level, while remaining gestagenically inert. In this case, mifepristone counteracts glucocorticosteroids (GCS) at the receptor level.

  • The action of the agent is aimed at increasing the contractility of the muscular component of the uterine walls by stimulating the production of the substance interleukin 8 (the main pro-inflammatory chemokine) in the choriodecidual tissue.
  • Mifepristone is able to increase the sensitivity of the muscular tissue of the uterus to biologically active substances - prostaglandins.
  • In order to increase the effect, a therapeutic course of synthetic prostaglandin analogs is prescribed simultaneously with this drug. As a result, scaly exfoliation of the amniotic membrane and expulsion (falling out) of the fetal egg occurs.

special instructions

  • Patients should be informed that if there is no effect from the use of the drug on the 10-14th day, the pregnancy should be terminated in a different way, since congenital malformations in the fetus are possible.
  • The use of Mifegin requires the prevention of Rh allo immunization and other activities associated with abortion.
  • Patients with prosthetic heart valves or infective endocarditis should be given concomitant preventive treatment antibiotics.
  • The drug should be used in obstetric and gynecological medical institutions.

There are a lot of drugs on the domestic pharmacological market that are intended for medical abortions.

One of them is Mifegin.

As part of the drug, the active substance is mifepristone.

It is an antiprogestogen that blocks progesterone at the receptor level.

It causes contraction of the uterus, softening of its cervix and, ultimately, the expulsion of the fetal egg.

Mifegin is today considered one of the most popular drugs that are used for medical abortion in the early stages.

The drug is used, as a rule, for periods up to 42 days, as well as at home as a means of emergency contraception within 72 hours after unprotected intercourse.

However, in order to understand how much Mefigin needs to be taken so that its effect on the body is gentle and at the same time leads to the desired result, it is worthwhile to better study the mechanism of its action.

What happens after admission?

If the patient is healthy and the examination has proved the possibility of using this drug, Mifegin is usually prescribed once at a dose of 600 mg (3 tablets) only with constant medical supervision.

When will the drug work?

It is difficult to answer unequivocally the question of how Mifegin works and how long after taking the fetal egg will be rejected.

It depends on the state of health and individual features female patients.

Maximum concentration active substance, according to research data, in the blood is reached 1.3 hours after ingestion.

Therefore, after a woman has taken the pills, it is recommended to stay in the clinic for 2 hours under the supervision of specialists. This will avoid the development of dangerous side effects.

How many hours does Mifegin work? Already 18 hours after ingestion, 50% of the dose of Mifegin that enters the body is excreted through the urinary system. The minimum concentration of the drug in the blood is determined on average after 72 hours, so that the active effect medicinal product on the body continues for 3 days.

What enhances or weakens the effect of the drug?

After a woman has taken the drug, the effect of Mifegin does not always lead to positive result. Since the drug can seriously affect the development of the fetus, doctors categorically do not recommend leaving the child.

In such cases, usually 36-48 hours after taking Mifegin, you must additionally drink the drug. female hormone prostaglandin, which will increase the contractility of the uterus, in the following doses:

  • misoprostol - 400 micrograms, if no more than 49 days have passed since the last menstruation;
  • gemiprost - 1 mg intravaginally, if no more than 63 days have passed since the last menstruation.

Most gynecologists prescribe prostaglandins according to the following scheme: the patient takes 2 tablets at a time, and after 3 hours - 2 more tablets. After that, 97% of medical abortion is successful.

Strengthen the effect of the drug and provoke the appearance of unwanted side effects - nausea, vomiting, headache, fever, pain in the abdomen, severe vaginal bleeding or exacerbation of chronic inflammatory diseases reproductive system- such concomitant diseases in a woman who wants to terminate a pregnancy can:

  1. Obstructive diseases respiratory system, including bronchial asthma.
  2. Arrhythmias.
  3. Heart failure.
  4. Arterial hypertension.

The abortive effect can be weakened by the simultaneous use of non-steroidal anti-inflammatory drugs with Mifegin or non-narcotic analgesics(the course of treatment with them should be prescribed no earlier than 8-10 days after taking drugs with the active substance mifepristone), as well as acetylsalicylic acid.

The effect of Mifegin on the body can be very strong in patients suffering from infectious endocarditis or those who have an artificial heart valve. For this reason, prophylactic antibiotic therapy is prescribed in such cases.

The completeness of abortion when taking this drug containing mifepristone depends on:

  • the woman's health status (in particular, the cervix) and the presence of serious chronic diseases;
  • the age of the pregnant woman;
  • compliance with the rules of admission specified in the instructions;
  • gestational age (it is optimal to terminate the pregnancy for a period of no more than 3-4 weeks).

Pharmacokinetics

Mifegin belongs to the group of steroid-type antiprogestogenic drugs that stop the synthesis of the "pregnancy hormone" progesterone at the receptor level.

This dramatically reduces the flow of this substance to the embryo and reduces the number of capillaries in the endometrium, which contributes to the contraction of this organ and the separation of the fetal egg from the walls of the uterus.

Mifegin improves the ability of the myometrium to contract, providing the release of a special substance - interleukin-8 - in cells of the choriodecidual type.

It is it that enhances the sensitivity of the myometrium to the effects of prostaglandins and provides an abortive effect.

Bleeding after using the drug usually begins within a day. The presence of clots in the discharge indicates an abortion that has begun.

On the 3-4th day after taking Mifegin, discharge of a yellowish or green tint may appear, indicating the development of a sexual infection.

Brown discharge, not accompanied severe pain, pungent odor, itching and burning, are considered the norm and can last up to 5-10 days.

A woman will be able to understand that an abortion has begun by the following symptoms:

  1. Uterine bleeding of the menstrual type.
  2. Pain in the abdomen, sometimes requiring pain medication.
  3. Nausea and vomiting.
  4. Diarrhea.
  5. Increased fatigue and dizziness.

A couple of weeks after using Mifegin, it is recommended to undergo an ultrasound examination to check if there are any remnants of the fetal egg in the uterus.

If the pregnancy is more than 4 weeks or the drug was not taken in combination with prostaglandins, it may not work. Then you have to resort to surgical or mini-abortion.

Although most of Mifegin is excreted in just 72 hours, after termination of pregnancy with this drug, even the most enduring female body will recover for at least 3-4 weeks.

This period can be reduced by observing a few simple rules:

  • exclusion of sexual activity for at least a month in order to avoid infection of the genital tract and increased bleeding;
  • refusal of alcoholic beverages;
  • a nutritious diet rich in vitamins;
  • exclusion of intensive physical activity and training;
  • compliance with the rules of personal hygiene.

And so, in our article, you learned how long Mifegin begins to act, how much to take and what effect it has.

The pharmacokinetics of Mifegin is quite simple, but its use requires consultation with a doctor. The consequence of home use of the drug may be its unpredictable effect on the body, so you should not joke with this.

Mifegin (Mifegyn)

Name: Mifegin (Mifegyn)

Name

Mifegin (Mifegyn)

pharmachologic effect

Mifegin is a synthetic drug with a pronounced antiprogestogenic effect. Mifegin contains the active ingredient mifepristone, a substance that blocks the effects of progesterone at the receptor level.

The drug Mifegin is not characterized by gestagenic activity, there is some antagonism of mifepristone with glucocorticosteroid hormones (due to the competition of mifepristone and glucocorticosteroids at the level of binding to receptors).

When taking the drug Mifegin, there is an increase in the contractility of the myometrium due to an increase in the release of interleukin-8 in choriodecidual cells, as well as an increase in the sensitivity of the myometrium to the action of prostaglandins (Mifegin can be prescribed with synthetic analogues of prostaglandins to increase efficiency). Under the influence of the drug Mifegin, desquamation of the decidua occurs, as well as the excretion of the fetal egg.

After oral administration of 600 mg of mifepristone, the peak plasma concentration is reached within 1.3 hours and is 1.98 mg / l. The absolute bioavailability of the drug Mifegin reaches 69%.

About 98% of the accepted dosage of mifepristone binds to plasma proteins (mainly albumin and alpha-1-acid glycoprotein). After the distribution of mifepristone, excretion is slow, about half of the accepted dosage is excreted within 12-72 hours.

Half-life active component medication Mifegin reaches 18 hours.

Indications for use

Mifegin is used to terminate uterine pregnancy in the early stages (no more than 42 days of amenorrhea).
Mifegin can also be prescribed for the preparation and induction of labor in case of intrauterine fetal death (the use of mifepristone is offered mainly if the use of oxytocin or prostaglandins is undesirable).

Mode of application

To terminate a uterine pregnancy (for a period of no more than 42 days of amenorrhea), they generally prescribe 600 mg of mifepristone (3 tablets of Mifegin) once under the supervision of a doctor.

After 36-48 hours, the appointment of prostaglandins is recommended: misoprostol at a dose of 400 mcg during pregnancy with a delay in menstruation up to 49 days or hemiprost at a dose of 1 mg intravaginally during pregnancy with a delay in menstruation up to 63 days.

After using medication, a woman should be under the supervision of a doctor for at least 2 hours. 36-48 hours after taking mifepristone, ultrasound diagnostics are recommended.

In addition, 8-14 days after taking the medicine Mifegin, a mandatory clinical, laboratory (determination of the level of beta-chorionic hormone) and ultrasound are carried out.

If after 14 days a high level of beta-chorionic hormone persists or during clinical and ultrasound examination it is revealed that the result of mifepristone is insufficient (incomplete abortion or continuation of the pregnancy), vacuum aspiration is indicated, followed by a histological examination of the aspirate. If, after taking mifepristone, the pregnancy has continued, abortion by other methods is necessary, since Mifegin can cause severe malformations. To induce labor, 200 mg of mifepristone (1 tablet of Mifegin) is often prescribed under medical supervision. After 24 hours, a second dose of 200 mg of mifepristone (1 tablet of Mifegin medication) is prescribed. 48-72 hours after taking the second dosage of the drug, a gynecological examination should be performed and, if necessary, oxytocin or prostaglandins should be prescribed.

The use of the drug Mifegin should be carried out simultaneously with the prevention of Rh-aloimmunization and common methods used during abortion.

Side effects

When using the drug Mifegin, the development of undesirable effects directly related to the therapy procedure, as well as systemic adverse reactions caused by mifepristone.

Undesirable effects associated with the treatment procedure often manifest themselves in the form spotting from the genital tract, as well as pain in the lower abdomen and exacerbations inflammatory processes uterus and appendages.

Mifegin is not used in patients suffering from adrenal insufficiency, acute and chronic form renal or hepatic insufficiency, porphyria, uterine myoma, anemia and hemostasis disorders, as well as patients who have been receiving glucocorticosteroids for a long time.

Mifegin is not used in women with uterine scars or severe extragenital pathology, as well as women suffering from inflammatory diseases of the reproductive system. Special care must be taken when prescribing Mifegin to smoking women over the age of 35. Mifegin is not prescribed for suspected intrauterine pregnancy.

In addition, it is not suggested to prescribe mifepristone during pregnancy, not confirmed by clinical studies, with amenorrhea for more than 42 days, which occurred while using an intrauterine contraceptive system or taking oral contraceptives.

For the induction of labor, mifepristone should not be prescribed to women with eclampsia, preeclampsia, severe gestosis, post-term or premature pregnancy. Caution is suggested when prescribing mifepristone to patients suffering from chronic obstructive pulmonary diseases (including bronchial asthma), severe arterial hypertension, heart failure and cardiac arrhythmias .
