Active ingredient: progesterone Active ingredient concentration (%): 2, 5%
Progestin Hormone yellow body. Causes the transition of the mucous membrane of the uterus from the phase of proliferation caused by follicular hormone to the secretory phase, and after fertilization contributes to its transition to the state necessary for the development of a fertilized egg. Reduces the excitability and contractility of the muscles of the uterus and fallopian tubes, stimulates the development of the terminal elements of the mammary gland. Does not possess androgenic activity. Progesterone has a weak effect on protein metabolism, promotes fat deposition and glucose accumulation in the liver, and also reduces sodium reabsorption in the renal tubules. Progesterone has a blocking effect on the secretion of hypothalamic factors of LH and FSH release, inhibits the formation of gonadotropic hormones in the pituitary gland and inhibits ovulation.
After the i / m injection is absorbed quickly and almost completely. Metabolized in the liver, most metabolites form conjugates with glucuronic and sulfuric acids. T1 / 2 of plasma is a few minutes. Excreted in the urine - 50-60% and with the feces - more than 10%. The number of metabolites that are excreted in the urine varies depending on the phase of the corpus luteum.
