Pharmacological action
Pharmacodynamics
Combined (three-phase) oral contraceptive estrogen-gestagen drug. When taken, inhibits the pituitary secretion of gonadotropic hormones.
Sequential administration of film-coated tablets of the drug, containing different amounts of gestagen (levonorgestrel) and estrogen (ethinyl estradiol) provides concentrations of these hormones in the blood, close to their concentrations during the normal menstrual cycle, and promotes secretory transformation of the endometrium. The contraceptive effect is associated with several mechanisms.
Under the influence of levonorgestrel, there is a blockade in the release of releasing factors (luteinizing and follicle-stimulating hormones) of the hypothalamus, inhibition of pituitary secretion of gonadotropic hormones, which leads to inhibition of maturation and the exit of the egg ready for fertilization (ovulation). Ethinyl estradiol maintains a high viscosity of cervical mucus (it makes it difficult for sperm to enter the uterine cavity). Along with the contraceptive effect, the menstrual cycle is normalized, due to the replenishment of the level of endogenous hormones with the hormonal components of Tri-Regol ® tablets. In seven-day periods, when the next break in taking the drug follows, uterine bleeding occurs.
Pharmacokinetics of
Levonorgestrel is rapidly absorbed (less than 4 hours). Levonorgestrel does not have a first pass effect through the liver. The elimination half-life makes 8-30 hours (on average 16 hours). Most of the levonorgestrel in the blood binds to albumin and to sex hormone-binding globulin.
Ethinyl estradiol is rapidly and almost completely absorbed from the gastrointestinal tract. The maximum plasma concentration is reached in the range of 1-1.5 hours. The half-life is 26 ± 6.8 hours. Ethinyl estradiol has the first pass effect through the liver (the so-called first pass effect). Metabolism occurs in the liver and intestines.
When ingested, ethinyl estradiol is excreted within 12 hours from blood plasma.
Ethinyl estradiol metabolites: water-soluble derivatives of sulfate or glucuronide conjugation enter the intestines with bile, where they undergo disintegration using intestinal bacteria. 60% of levonorgestrel is excreted by the kidneys, 40% through the intestines, 40% of ethinyl estradiol is excreted by the kidneys and 60% through the intestines.
Indications
Oral contraception.
