Clinical Pharmacology

EURA is a contraceptive for transdermal use. It inhibits the gonadotropic function of the pituitary gland, inhibits the development of the follicle and interferes with the process of ovulation. The contraceptive effect is enhanced by increasing the viscosity of cervical mucus and reducing the susceptibility of the endometrium to the blastocyte. Pearl Index - 0.90.

The frequency of pregnancy does not depend on such factors as age, race, and increases in women weighing more than 90 kg.


Suction and distribution

Css Norelgestromine and ethinyl estradiol in serum are reached 48 hours after the application of TTC Eur and are 0.8 ng / ml and 50 pg / ml, respectively.

With long-term use TTC Evra Css and AUC increase slightly. There were no significant changes in temperature and exercise conditions. Css and AUC of norelgestromine, a AUC of ethinyl estradiol increases slightly during exercise, while Css remains unchanged.

C target valuesss norelgestromine and ethinyl estradiol are maintained for 10 days with TTC applications, i.e. The clinical efficacy of TTC can be maintained even if the woman conducts another replacement of TTC 2 full days later than the scheduled seven-day period.

Norelgestromin and norgestrel (serum metabolite of norelgestromin) have a high degree (more than 97%) of binding to serum proteins. Norelgestromin binds to albumin, norgestrel binds predominantly to the globulins that bind the sex hormones. Ethinyl estradiol has a high degree of binding to serum albumin.


Norelgestromin is metabolized in the liver, with the formation of the metabolite norgestrel, as well as various hydroxylated and conjugated metabolites. Ethinyl estradiol is metabolized to various hydroxylated compounds and their glucuronide and sulfate conjugates. Progestogens and estrogens inhibit many microsomal liver enzymes of cytochrome P system450 (including CYP3A4, CYP2C19).


Average t1/2 norelgestromine and ethinyl estradiol is about 28 h and 17 h, respectively. Metabolites of norelgestromine and ethinyl estradiol are excreted in the urine and feces.

Pharmacokinetics in special clinical situations

C valuesss and AUC of norelgestromine and ethinyl estradiol decreases slightly with increasing age, body weight, or body surface area.

Evra® [Norelgestromin, Ethinyl Estradiol]

Dosage and Administration

The patient should be informed that in order to achieve the maximum contraceptive effect, it is necessary to strictly follow the instructions on the use of Evr TTC. Only one TTS can be used at a time.

Each used TTC is removed and immediately replaced with a new one on the same day of the week (“replacement day”) on the 8th and 15th days of the menstrual cycle (2nd and 3rd week). TTC can be changed at any time of the day of replacement. During the 4th week, from the 22nd to the 28th day of the cycle, TTC is not used. A new contraceptive cycle begins the day after the end of the 4th week; the following TTS should be stuck, even if the menstruation was not or it has not ended.

Under no circumstances should the break in the TTS Evra application be longer than 7 days, otherwise the risk of pregnancy is increased. In such situations, for 7 days it is necessary to simultaneously use a barrier method of contraception, since The risk of ovulation increases with each day that the recommended duration of the period, free from the use of TTC, is exceeded. In the case of sexual intercourse during such an extended period, the probability of conception is very high.

Start applying TTC Evra

If during the previous menstrual cycle a woman did not use a hormonal contraceptive

Contraception using TTC Evra begin on the first day of menstruation. One TTC Evra is glued to the skin and is used all week (7 days). The day of sticking the first TTS Evra (1st day / start day) determines the next days of replacement. Replacement day will be on the same day of each week (8th and 15th days of the cycle). On the 22nd day of the cycle, the TTC is removed, and from the 22nd to the 28th day of the cycle, the woman does not use the ETC TTC. The next day is considered the first day of the new contraceptive cycle. If a woman starts using TTC Evra not from the first day of the cycle, then barrier methods of contraception should be used simultaneously for the first 7 days of the first contraceptive cycle.

If a woman switches from using a combined oral contraceptive to using TTC Evra

TTC Evra should be applied to the skin on the 1st day of menstruation, which began after discontinuation of the combined oral contraceptive use. If menstruation does not begin within 5 days after taking the contraceptive pill, then it is necessary to exclude pregnancy before starting using TTC Evra.

If the use of Evra begins after the 1st day of menstruation, then within 7 days it is necessary to simultaneously use barrier methods of contraception.

If more than 7 days have passed after taking the last contraceptive pill, then a woman may experience ovulation, and therefore she should consult a doctor before starting to use TTC Evra. Sexual intercourse during this prolonged period, free from taking contraceptive pills, can lead to pregnancy.

If a woman moves from using drugs containing progestogen only to using TTC Evra

A woman can go on any day with a drug containing only progestogen (on the day the implant is removed, on the day when another injection should be given), but during the first 7 days of using ETC TTS, a barrier method should be used to enhance the contraceptive effect.

After abortion or miscarriage

After an abortion or miscarriage before the 20th week of pregnancy, you can immediately start applying TTC Evra. If a woman begins to use TTC Evra immediately after an abortion or miscarriage, then additional methods of contraception are not required. A woman should know that ovulation can occur within 10 days after an abortion or miscarriage. After an abortion or miscarriage in the 20th week of pregnancy or later, the use of Evra TTC can be started on the 21st day after the abortion or miscarriage, or on the 1st day of the first menstruation.

After childbirth

Women who do not breastfeed should begin using the Evra TTC no earlier than 4 weeks after delivery. If a woman begins to use TTC Evra later, then during the first 7 days she should additionally use a barrier method of contraception. If there was sexual intercourse, it is necessary to exclude pregnancy before starting the use of TTC Evra, or a woman must wait for the first menstruation.

With full or partial peeling off TTC Evra

If TTC Evra is completely or partially peeled off, then an insufficient amount of its active ingredients enters the blood.

Even with a partial peeling of the TTC Evra in less than a day (up to 24 hours): you should re-glue the TTC Evra in the same place or immediately replace it with a new TTC Evra. Additional contraceptives are not required. The next TTC Evra needs to be glued on a regular “replacement day”.

With a partial peeling off for more than a day (24 hours or longer), and also if a woman does not know exactly when TTC Evra is partially or completely peeled off - the onset of pregnancy is possible. A woman should immediately start a new cycle, sticking a new TTC Evra and consider this day as the first day of the contraceptive cycle. Barrier contraceptive methods should be used at the same time only in the first 7 days of the new cycle.

You should not try to re-glue TTC Evra if she lost her adhesive properties; instead, you must immediately glue the new TTC Evra. Do not use additional adhesive tapes or bandages to hold TTC Evra in place.

If the next days of replacing TTC Evra are missed

At the beginning of any contraceptive cycle (1st week / 1st day): with an increased risk of pregnancy, a woman should stick the first TTS of Evra of a new cycle as soon as she remembers. This day is considered a new "1st day" and a new "replacement day" is being counted. Non-hormonal contraception should be simultaneously applied during the first 7 days of the new cycle. In the case of sexual intercourse during such an extended period, conception may occur without the use of Evra's TTC.

In the middle of the cycle (2nd week / 8th day or 3rd week / 15th day):

—If 1 day or 2 days have passed from the day of replacement (up to 48 hours): the woman should immediately paste the new TTC. The following TTC needs to be glued on a regular “replacement day”. If during the 7 days preceding the first missed day of TTS attachment, the use of TTS was correct, then additional contraception is not required;

—If more than 2 days have passed since the replacement date (48 hours or more): there is an increased risk of pregnancy. A woman should stop the current contraceptive cycle and immediately start a new 4-week cycle by pasting a new Evra TTC. This day is considered a new "1st day" and a new "replacement day" is being counted. Barrier contraception should be applied simultaneously during the first 7 days of the new cycle;

—At the end of the cycle (4th week / 22nd day): if the TTC is not deleted at the beginning of the 4th week (22nd day), then it should be removed as soon as possible. The next contraceptive cycle should begin on the regular “replacement day”, which is the day after the 28th day. Additional contraception is not required.

Change day replacement

In order to postpone menstruation for one cycle, a woman must glue a new TTC Evra at the beginning of the 4th week (22nd day), thereby skipping the period free from using TTC Evra. Intermenstrual bleeding or spotting may occur. After 6 consecutive weeks of TTS use, there should be a 7-day interval free from TTS use. After the end of this interval, regular use of the drug is resumed.

If a woman wants to change the replacement day on the day appointed for this purpose during the week free of use, she must complete the current cycle by removing the third TTC of Evra; A woman can choose a new replacement day by sticking the first TTS of Evra of the next cycle on the selected day. In no case should the period free from using TTC Evra be more than 7 days. The shorter this period, the higher the likelihood that a woman will not have another menstruation, and during the next contraceptive cycle, intermenstrual bleeding or spotting may occur.

Mode of application

TTC Evra should be glued to clean, dry, intact and healthy skin of the buttocks, abdomen, outer surface of the upper part of the shoulder or upper body with minimal hair growth, in areas where it will not come into contact with tight clothing.

In order to avoid possible irritation, each following TTS of Evra should be glued to another area of ​​skin, this can be done within the same anatomical region.

TTC Evra must be pressed tightly so that its edges are in good contact with the skin. To prevent the adhesive properties of TTS from falling, Evra should not apply make-up, creams, lotions, powders and other local products on those areas of the skin where it is glued or will be glued.

A woman should inspect the TTS Evra on a daily basis in order to be confident in its firm attachment.

Used TTC must be carefully disposed of in accordance with the instructions.

Do not use on the area of ​​the mammary glands, as well as on hyperemic, irritated or damaged skin.


WITH caution should be used with family history indications of venous or arterial thromboembolism in siblings or parents at a relatively young age; with prolonged immobilization; obesity (body mass index more than 30 kg / m2calculated as the ratio of body weight in kilograms to the square of height in meters); thrombophlebitis of superficial veins and varicose veins; dyslipoproteinemia; hypertension; lesions of the valvular apparatus of the heart; atrial fibrillation; diabetes; systemic lupus erythematosus; hemolytic-uremic syndrome; Crohn's disease; ulcerative colitis; abnormal liver function; hypertriglyceridemia (including in family history); acute liver dysfunction during a previous pregnancy or previous use of sex hormones; in violation of the menstrual cycle; impaired renal function.

Drug interactions

Hydantoins, barbiturates, primidone, carbamazepine and rifampicin, as well as oxcarbazepine, topiramate, felbamate, ritonavir, griseofulvin, modafinil, and phenylbutazone, can cause an acceleration of the metabolism of sex hormones, which can lead to interfusional bleeding or ineffectiveness, and can be ineffective or cause ineffective. of pregnancy. The mechanism of interaction of these drugs and the active ingredients of TTC Evra is based on the ability of the above listed drugs to induce liver enzymes, with the participation of which the sex hormones are metabolized. The maximum induction of enzymes is usually achieved no earlier than 2-3 weeks, and can last for at least 4 weeks after discontinuation of the corresponding drug.

Acceptance of herbal preparations containing St. John's wort (Hypericum perforatum) concurrently with the use of Evra TTC may lead to a loss of contraceptive effect. Women who have taken these herbal remedies may experience intermenstrual bleeding and unwanted pregnancy. This is due to the fact that St. John's wort induces enzymes that metabolize sex hormones. Inducing effect may persist for 2 weeks. after the abolition of the herbal preparation containing St. John's wort.

The loss of the contraceptive effect may be caused by antibiotics (including ampicillin and tetracyclines). A study of pharmacokinetic interactions showed that oral administration of tetracycline hydrochloride 3 days before and for 7 days while using TTC Evra does not have a significant effect on the pharmacokinetics of norelgestromin or ethinyl estradiol.

Pregnancy and Lactation

The drug Evra is contraindicated during pregnancy and lactation.

Special instructions

There is no clinical evidence that, in any aspect, the transdermal contraceptive system is safer than oral contraceptives.

Before starting or resuming the use of Evra TTS, a detailed medical history (including family history) should be collected and pregnancy should be excluded. It is necessary to measure blood pressure and conduct a physical examination, taking into account contraindications and warnings.

If hereditary susceptibility to venous thromboembolism is suspected (if venous thromboembolism occurred in a brother, sister or parents at a relatively young age), a woman should be referred for consultation to a specialist before deciding on the use of hormonal contraception.

The risk of vascular complications is increased in women with superficial vein thrombophlebitis and varicose veins, as well as in obesity (body mass index of more than 30 kg / m2).

With prolonged immobilization, after extensive surgery on the lower limbs or severe injury, it is recommended to stop the use of hormonal contraceptives (during a planned operation, this should be done 4 weeks before it) and resume hormonal contraception no earlier than 2 weeks. after complete remobilization.

Some epidemiological studies have revealed an increased risk of cervical cancer in women who have been using combined oral contraceptives for a long time.

Women taking combined oral contraceptives may develop liver tumors, which can cause life-threatening intra-abdominal bleeding. If women who use TTC Evra have severe upper abdominal pain, an enlarged liver or symptoms of intra-abdominal bleeding, a differential diagnosis should be made to rule out a possible liver tumor.

In women with hypertriglyceridemia or this disease in the family history, the risk of pancreatitis in the case of the use of combined hormonal contraceptives may be increased.

If a pharmacologically uncontrolled arterial hypertension occurs in women during the use of combined hormonal contraceptives, the drug should be canceled. The use of TTC Evra can be resumed after the normalization of blood pressure.

It was reported that oral administration of combined hormonal contraceptives may cause or worsen the diseases listed below, but there is no convincing evidence of their connection with the use of combined oral contraceptives. These include: jaundice and / or pruritus associated with cholestasis; cholelithiasis; porphyria; systemic erythematosus; hemolytic uremic syndrome; Chorea Sydenham; gestational herpes associated with otosclerosis hearing loss. Hormonal contraceptives can affect some endocrine parameters, liver function markers and blood components:

- increases the concentration of prothrombin and coagulation factors VII, VIII, IX and X; decreases the level of antithrombin III; decreases the level of protein S; increased norepinephrine platelet aggregation;

- increases the concentration of thyroxin-binding globulin, which causes an increase in the concentration of total thyroid hormone, which is measured by the content of iodine associated with protein, the content of T4 (determined using chromatography or radioimmunoassay); reduced binding of free T3 ion exchange resin, as evidenced by the increase in the concentration of thyroxin-binding globulin, the concentration of free T4 does not change. Serum concentration of other binding proteins may be increased;

- increases the concentration of globulins that bind sex hormones, which leads to an increase in concentrations of total circulating endogenous sex hormones. However, concentrations of free or biologically active sex steroids are reduced or remain unchanged.

Women using TTC Evra may slightly increase concentrations of LDL-C, total cholesterol, LDL-C and TG, while the ratio of LD-C / LDL / C-HDL may remain unchanged.

Hormonal contraceptives may cause a decrease in serum folate concentrations. This can have potentially clinically significant consequences if a woman has a pregnancy shortly after withdrawing a hormonal contraceptive. Currently, all women are advised to take folic acid during and after hormonal contraception.

Combined hormonal contraceptives can affect peripheral insulin resistance and glucose tolerance, but there is no evidence of the need to change the treatment of diabetes mellitus during the use of combined hormonal contraceptives. At the same time, the condition of diabetic patients should be carefully monitored, especially at the early stage of the use of the Evra TTC.

Exacerbation of endogenous depression, epilepsy, Crohn's disease and ulcerative colitis has been reported in women taking combined oral contraceptives.

Women who have had hyperpigmentation of their skin during pregnancy should avoid exposure to sunlight or artificial ultraviolet light while wearing TTC Evra.Often, such hyperpigmentation is not completely reversible.

Women should be informed that hormonal contraceptives do not protect against HIV infection (AIDS) and other sexually transmitted diseases.

Women who take drugs that induce microsomal enzymes (hydantoins, barbiturates, primidone, carbamazepine, rifampicin, oxcarbazepine, topiramate, felbamate, ritonavir, griseofulvin, modafinil, and phenylbutazone), and antibiotics (except tetracycline) should temporarily use a barrier method of contraception in addition to the use of TTC Evra or choose another method of contraception. The barrier method should be applied during the course of treatment with the above preparations, as well as within 28 days after discontinuation of the inducers of microsomal enzymes and within 7 days after discontinuation of antibiotics. If the period for taking concomitant drugs exceeds the 3-week cycle of using ETC's TTC, then a new contraceptive cycle should be started immediately after the previous one, that is, without the usual period free from the use of TTC. Women receiving long-term therapy with drugs that induce liver enzymes should choose another method of contraception.

When prescribing Evra drugs that are metabolized by CYP3A4, CYP2C19 isoenzymes, especially those with a narrow therapeutic index (for example, cyclosporine), against the background of TTC use, exclude the possibility of a clinically significant interaction.

When using any combined hormonal contraceptives, the menstrual cycle may be disturbed (spotting or intermenstrual bleeding), especially in the first months of using these remedies. The duration of the adaptation period is about three cycles.

If during the use of TTS Evra in accordance with the recommendations, the persistence of intermenstrual bleeding is observed or such bleeding occurs after previous regular cycles, then other reasons besides the use of TTC should be taken into account. It should be borne in mind the possibility of non-hormonal causes of menstrual disorders and, if necessary, conduct an adequate diagnostic examination to exclude organic disease or pregnancy.

Some women in the period, free from the use of TTC Evra menstruation may not occur. If a woman violated the instructions for use in the period preceding the first failed menstruation, or if she did not have two menstruations after interruptions in the use of TTC, it is necessary to exclude pregnancy before continuing to use TTC Evra.

In some women, the abolition of hormonal contraceptives can provoke the occurrence of amenorrhea or oligomenorrhea, especially if they are present before the onset of hormonal contraception.

If the application of TTS Evra causes skin irritation, you can glue the new TTS to another area of ​​skin and wear it until the next day of replacement.

In women weighing 90 kg or more, the effectiveness of contraception can be reduced.

If symptoms of liver dysfunction occur, the use of combined hormonal contraceptives should be stopped until the normalization of liver function markers.

In case of a relapse of pruritus associated with cholestasis, which occurred during a previous pregnancy or prior use of sex hormones, the combined hormonal contraceptives should be canceled.

The safety and effectiveness of TTC Evra are established only for women from 18 to 45 years.

Recycling Recommendations

Immediately after removing the TTS from the bag, it should be firmly glued to the skin. After removing TTC, it still contains significant amounts of active ingredients.Residual hormones can harm the environment if they enter the water, and therefore used TTC should be carefully disposed of. To do this, separate the special adhesive film from the outside of the bag. Place the used TTS in the bag in such a way that its sticky side faces the painted area on the bag, and lightly press it to seal. The sealed bag is thrown away. Used TTC should not be thrown into the toilet or into the sewer.


Symptoms: nausea, vomiting, vaginal bleeding.

Treatment: there is no specific antidote. TTC should be removed and symptomatic therapy should be performed.
