Fapmakologicheskoe action
Trikvilar effect when taken orally and is the first three-stage low-dose, progestogen-estrogen drug to prevent pregnancy. As a progestin component (progestin) it comprises a derivative of 19-nortestosterone - levonorgestrel, surpassing the activity as the hormone progesterone luteum, and its synthetic analogue pregnin and acts at the receptor level without preliminary metabolic transformations. Trikvilar estrogen component is a highly effective means of oral estrogen - ethinyl estradiol.
A distinctive feature of trikvilar compared with monophasic contraceptive is, it is a set of pills, containing varying amounts of (3 dose) progestogen and estrogen, serial reception of which simulates physiological fluctuations of sex hormones in the blood during the menstrual cycle. Besides, product contains a lower dose of hormones, contraceptives than the first and second generations, and therefore it is less, than they, influence on metabolic processes (lipids, blood clotting), other causes fewer side effects. Trikvilar contraceptive effect is primarily due to the ability to block the release of levonorgestrel-releasing factor (luteinizing hormone and follicle-stimulating) gipotalamusa, depress the secretion of pituitary gonadotropins and thus inhibit ovulation. Its contraceptive effect is enhanced ethinylestradiol - the synthetic analogue of the follicular hormone estradiol, involved with the hormone of the corpus luteum (progestin, progestogen) the implementation of the menstrual cycle. In addition to these central and peripheral mechanisms preventing the maturation of the ability to fertilize the egg, trikvilar contraceptive effect is due to the conservation and under its influence the high viscosity of the cervical mucus, making it difficult to hit the sperm into the uterus.
The dosages of estrogen and progestin components Trikvilar virtually no impact on the basic functions of the central and peripheral nervous system, blood circulation, activities of other body systems.
Both active ingredients after administration trikvilar dragees rapidly and completely absorbed from the gastrointestinal tract. Their maximum plasma concentration is reached in the range 0,5-1 o'clock. Subsequently, the concentration level is characterized by a biphasic decline with a half-life 2 or 24 hours for levonorgestrel and 1-3 or 24 hours for ethinyl estradiol. Daily re-taking the drug is not accompanied by a noticeable cumulation of active substances and their metabolites.
Selecting components trikvilar: levonorgestrel - through the kidneys (50-60%) and liver (40-50%), and ethinyl estradiol - by 40% via the kidneys and 60% - Through the liver. In both cases the half-life is about 24 hours.
The drug can be allocated to human milk. When this selection is less progestogen 0,01 % of the administered dose, and estrogen - about 0,02%.
Due to lack of levonorgestrel metabolize fully cooperates with the organs and systems of the body, and ethinyl estradiol for this interaction is around 40-60%.
