Schering AG has developed a progestational component formula for modern oral contraceptives - drospirenone. The innovative tool was named Yarina - by the name of the girl chosen by the “face” of this brand. A contraceptive has tremendous advantages over traditional drugs.
Yarina - hormonal pills. This oral contraceptive is a modern way to protect a woman from an unwanted pregnancy. Yarina is a hormonal low-dose monophasic drug for contraception. Its effect is due to the processes of inhibition of ovulation.
When taking the drug Yarina, whose side effects are minimal, a woman can choose the most favorable terms for conceiving a child.
Mechanism of action
The composition of this drug includes two components: drospirinone (3 mg) and ethinyl estradiol (30 mg), these substances are synthetic versions of the hormones - estrogen and progesterone.
Yarina, whose side effects are almost not observed, has an effect on the menstrual cycle of a woman. As you know, the level of sex hormones changes during the menstrual cycle. When the egg leaves the ovary, ovulation occurs, the endometrial layer of the uterus prepares for the introduction of the sperm. With non-fertilization of the egg, the hormonal level decreases. Then the whole cycle is repeated. Taking contraceptives makes the body behave as if ovulation has already occurred.
A remarkable feature of drospirenone is the prevention of fluid retention in the body, so when taking Yarina there is no weight gain.
Menses gradually become less painful, their duration decreases. Beneficial effect on the skin helps reduce acne.
