General characteristics. Structure:

Active agent: a triptorelina acetate of 4.12 mg that corresponds to the maintenance of a triptorelin of 3.75 mg

Excipients: copolymer of milk and glycolic acids, propylene glycol каприлокапрат.

Solvent: polysorbate 80, a dextran 70, sodium chloride, dihydrophosphate sodium a dihydrate, sodium hydroxide, water for and.




Pharmacological properties:

Active ingredient of drug Dekapeptil of depot - трипторелин - a synthetic analog a gonadotrophin-rileasing of hormone (GNRG). In a molecule of natural GNRG more expressed affinity to receptors of GNRG and longer, than at a natural molecule, half-life is result of replacement of the 6th amino-acid rest.
Initial effect of administration of drug Dekapeptil of depot is secretion stimulation a hypophysis of FSG and LG. After long stimulation (constant concentration of a triptorelin in blood) the hypophysis becomes insensitive to action of GNRG. As a result the level of gonadotrophins in blood decreases that leads to decrease in level of sex hormones to postkastratsionny or menopauzny level. The described effects are reversible.

Pharmacokinetics. Pharmacokinetic tests were carried out on patients with the confirmed diagnosis of endometriosis or a hysteromyoma, patients with a carcinoma of a prostate and healthy male volunteers.

Absorption. During the first hours after administration of drug in oil Dekaleptil of depot is registered Cmax of a triptorelin in a blood plasma considerably decreasing during 24 h. For the 4th day after an injection in oil concentration of a triptorelin in blood reaches the second maximum after which concentration decreases in a biekspanentsialny order to uncertain values for 44 days.
After п / to introduction increase in concentration of active ingredient happens more slowly in comparison with introduction in oil. Decrease in concentration of a triptorelin in blood happens more slowly, duration of decrease in concentration to uncertain values makes 65 days.
Repeated, at an interval of 28 days, a drug injection Dekapeptil depots, do not lead to increase in its concentration in blood. At in oil and п / to introductions concentration of a triptorelin in blood on the eve of the next injection decreased to 85 pg/ml and 100 pg/ml respectively.

At men constant biological availability of active component of a triptorelin makes 38.3% in the first 13 days of depot. Further release of drug becomes linear with average daily value of 0.92% of the entered dose.

Women in 27 days have researches, 35.7% of originally entered dose on average are defined, at the same time 25.5% of a dose are released in the first 13 days with the subsequent linear allocation, on average, on 0.73% of the entered dose daily.

Removal. Half-life of a triptorelin in plasma - 18.7 min., at the same time for natural a hormone gonadotrophin-rileasing this indicator makes 7.7 min. The clearance of a triptorelin (503 ml/min.) by 3 times more slowly, than at natural a hormone rileasing (1766 ml/min.) also consists of two components - bystry and slow removal. Less than 4% of a triptorelin in not changed look are removed with urine.


Indications to use:

endometriosis;
hysteromyoma;
— treatment of infertility using auxiliary reproductive technologies (including EKO and PE/transfer of an embryo/).

For men

— a symptomatic treatment of the progressing hormonedependent carcinoma of a prostate.
