Jolivette is a progestine hormonal drug. The main component is norethisterone.
Indications for use
Contraception. It also can be applied in the following cases:
- premenstrual syndrome;
- anovulatory metrorrhagia;
- dysmenorrhea (accompanied by a shortening of the secretory phase);
- endometrial glandular cystic hyperplasia;
- endometrial cancer;
- menopausal syndrome;
- diagnostic progesterone test;
- cessation and prevention of lactation;
- postponement of the next menstruation.
Mechanism of action
Jolivette is a progestogen. When entering the organism, Jolivette binds to the receptors of progesterone in target organs, including myometrium. Norethisterone in the cytoplasm of cells forms a complex with specific receptors that bind to the chromatin of target cells and changes the synthesis processes in them.
Norethisterone blocks the secretion of gonadotropin in the pituitary gland, thus preventing the onset of ovulation and maturation of the follicles, transferring the uterine lining from the proliferation phase to the secretory phase. Jolivette slows proliferative activity in the hyperplastic endometrium. It also promotes secretory transformation, development of atrophic changes in the stroma and epithelium of the glands and the decidual response of the stroma. After fertilization norethisterone promotes the transition of the mucous membrane of the uterus into a state that is favorable for the development of a fertilized egg.
Norethisterone reduces the contractility and excitability of the uterus muscles. Norethisterone increases the cervical mucus viscosity, thereby impeding the progress of sperm, disrupts the peristalsis of the fallopian tubes, reduces the sensitivity of the endometrium to the oocytes, thus disrupting the fertilized egg attachment. Many women do not have ovulation with norethisterone, which is confirmed by the lack of a peak increase in luteinizing hormone in the middle of the cycle and an increase in the level of progesterone.
