Pharmacological action
The active ingredient in Norkolut is norethisterone, which is mainly a progestogen-type norsteroid. Compared with other known gestagens, the drug, although it does not belong to the most active gestagens, yet its properties are unusually favorable for therapy.
With the so-called delay of mensis test (delaying menstruation), which is used to determine the effectiveness of gestagens, the drug exhibits the properties of weak gestagens. The compound turned out to be a medium-intensity progestive steroid when tested according to Hammerstein, as well as in the Clauberg test, which measures the dose needed to transform the endometrium.
In contrast to many gestagen compounds, norethisterone has a pronounced antiestrogenic character, and unlike other derivatives of nortestosterone in the body, only a small part of the compound is converted to estrogen.
At the same time, Paulsen under the influence of norethisterone in men observed gynecomastia, and in women an increase in mammary glands. In addition to the main gestagen action, the weak androgenic property of the compound was also determined. According to clinical and pharmacological studies, norethisterone blocks the production of follicle-stimulating hormone (FSH) and corpus luteum hormone (LH), and reduces the synthesis of steroids in the corpus luteum.
Norethisterone, which has mainly gestagenic properties, exhibits significant antiestrogenic and minimal estrogenic and androgenic effects, can be very widely used in obstetrics and gynecology.
