Excipients: peanut butter, lecithin soy, gelatin, глицерол, titanium dioxide.




Pharmacological properties:

Gestagenny drug. Progesterone, active agent of the drug Utrozhestan®, is hormone of a yellow body. Contacting receptors on a surface of cells of target organs, gets into a kernel where activating DNA, stimulates RNA synthesis.
Promotes transition of a mucous membrane of a uterus from a phase of the proliferation caused by follicular hormone in a secretory phase. After fertilization promotes transition to a state necessary for development of an oospore. Reduces excitability and contractility of muscles of a uterus and uterine tubes, stimulates development of trailer elements of a mammary gland.
Stimulating a proteinlipaza, increases fat reserves, increases glucose utilization. Increasing concentration of basal and stimulated insulin, promotes accumulation in a glycogen liver, increases production of gonadotropic hormones of a hypophysis; reduces an azotemia, increases removal of nitrogen with urine.
Activates growth of secretory department of an acinus of mammary glands, induces a lactation.
Promotes formation of a normal endometria.

Pharmacokinetics. At intake. Absorption. The micronized progesterone is absorbed from a GIT. Concentration of progesterone in a blood plasma gradually increases within the first hour, Cmax is noted in 1-3 h after reception.
Concentration of progesterone in a blood plasma increases from 0:13 ng/ml to 4:25 ng/ml in 1 h, to 11.75 ng/ml - in 2 h and makes 8.37 ng/ml in 3 h, 2 ng/ml - in 6 h and 1.64 ng/ml - in 8 h after reception.

Metabolism. The main metabolites which are defined in a blood plasma are 20-альфа-гидрокси-дельта-4-альфа-прегнанолон and 5 - alpha dihydroprogesterone.

Removal. It is removed with urine in the form of metabolites, 95% from them are made by glyukuronkonjyugirovanny metabolites, generally 3 alpha, 5 - beta прегнанедиол (прегнандион).
The specified metabolites which are defined in a blood plasma and in urine are similar to the substances which are formed at physiological secretion of a yellow body.

At intravaginalny introduction. Absorption. Absorption happens quickly, progesterone collects in a uterus. High level of progesterone is observed in 1 h after introduction. Cmax of progesterone in a blood plasma is reached in 2-6 h after introduction. At administration of drug on 100 mg of 2 times/days average concentration remains at the level of 9.7 ng/ml during 24 h.
At introduction in doses more than 200 mg/days concentration of progesterone corresponds to the I trimester of pregnancy.

Metabolism. 3 alpha, 5 - beta прегнанедиола are metabolized with education preferential. Level 5 - beta прегнанолона in plasma does not increase.

Removal. It is removed with urine in the form of metabolites, the main part is made by 3 alpha, 5 - beta прегнанедиол (прегнандион). It is confirmed by continuous increase in its concentration (Cmax of 142 ng/ml in 6 h).


Indications to use:

Progesterone-scarce states at women, including:
for intake
infertility owing to lyuteinovy insufficiency;
— syndrome of premenstrual tension;
— disturbances of a menstrual cycle owing to disturbance of an ovulation or anovulation;

Route of administration and doses:

Duration of therapy is established individually, depending on a clinical situation.

Such dose is usually applied for 60 days.
For maintenance of a lyuteinovy phase during a cycle of extracorporal fertilization it is recommended to enter intravaginalno from 200 to 600 mg/days, since day of an injection of a chorionic gonadotrophin during I and II trimesters of pregnancy.

For maintenance of a lyuteinovy phase in the spontaneous or induced menstrual cycle, at the infertility connected with dysfunction of a yellow body about 200-300 mg/days, since 17th day of a cycle for 10 days are recommended to enter intravaginalno, in case of a delay of periods and diagnosis of pregnancy treatment has to be continued.
