The transdermal contraceptive system EURA is a combined estrogen-progestative contraceptive. EURA is a thin beige patch, the contact area of which with the skin is 20 cm 2. Each patch contains 600 μg of EE and 6 mg of noreglestromine (a biologically active metabolite of norgestimate). According to the dosages of hormones entering the blood, the EURA system corresponds to the microdosed oral contraceptives. The systemic blood flow per day receives 150 mcg of noreglustromine and 20 mcg of EE.
The patch is glued on 1 of 4 possible zones (buttocks, chest, except for mammary glands, inner surface of the shoulder, lower abdomen). During 1 menstrual cycle, 3 patches are used, each of which is applied for 7 days. Replace the band-aid on the same day of the week. Then a 7-day break should be done, during which a menstrual reaction occurs.
The mechanism of action of the EURA system is due to suppression of ovulation and an increase in the viscosity of the cervical mucus. It was found that EURA suppresses ovulation as effectively as COC.
