Tri-regol is a combined three-phase contraceptive. It blocks the production of LH and FSH in the pituitary gland, increases the viscosity of cervical mucus, which interferes with the movement of sperm. Against the background of taking the drug, ovulation is suppressed.
Levonorgestrel quickly binds from the digestive tract, most of it binds to proteins. The elimination half-life can vary from 8 to 30 hours.
Ethinyl estradiol is rapidly and almost completely absorbed from the digestive tract, its maximum content in the blood is reached after 1-1.5 hours. In the liver and intestines, it is metabolized. The half-life is 26 ± 6.8 hours.
Regulon
Regulon is available in tablets, which are coated with a white or almost white shell. They are round, biconvex. The inscription “P8” is on one side of the tablet, and “RG” on the other.
The contraceptive effect is due to desogestrel and ethinyl estradiol.
In addition to them, Regulon includes inactive components:
- Vitamin E.
- E576.
- Aerosil.
- Povidone.
- Milk sugar.
- Potato starch.
- E570.
- Macrogol.
- Hypromellose.
Regulon refers to monophasic oral contraceptives. The mechanism of its action is associated with the suppression of the biosynthesis of gonadotropic hormones and ovulation. Against the background of contraceptive use, the viscosity of cervical mucus increases, as a result of which the movement of sperm cells along the endocercis slows down. In addition, the state of the endometrium changes, and a fertilized egg cannot be implanted.
A contraceptive has a positive effect on lipid metabolism, it increases the level of HDL in the blood. It normalizes the menstrual cycle, reduce blood loss during menstruation.
The medication has a positive effect on the condition of the skin, especially in the presence of acne.
Desogestrel is rapidly and almost completely absorbed from the digestive tract. Its bioavailability can vary from 62 to 81%. The maximum content is reached after 1.5 hours. In the liver and intestines, desogestrel is metabolized. It is excreted through the kidneys and intestines. The half-life is 30 hours.
Ethinyl estradiol is well absorbed from the digestive tract. The highest concentration is reached after 1 or 2 hours. Its bioavailability is 60%. Its connection with proteins is 100%. Passing through the liver, it undergoes metabolism. About 40% of the dosage taken is excreted in the urine, the rest with feces. The average half-life is one day.
