Pharmacodynamics and pharmacokinetics
The drug Esmiya (Esmya) contains a substance - ulipristal synthetic origin, are selective progesterone receptor modulator and different tissue-specific selective antiprogesteronovym action.
Ulipristal is characterized by a direct effect on endometrium . For most women, the application of 5 mg daily for menstrual cycle , Including sufferers myoma , Does not occur subsequent to this cycle menstrual bleeding . Upon termination of the pills, menstrual cycle Usually recovered within a month.
The direct effect of the drug on endometrium due to some of its specific changes characteristic for this class of drugs and provoked antagonistic action progesterone receptors . In 60% of women taking ulipristal over 3 months, histological changes are weak proliferating inactive epithelium with related asymmetry of growth and growth stroma , and cystic expansion glands progestagenic and estrogenic impacts on epithelium . These changes are reversible with the disappearance at the end of treatment, and are not related to endometrial hyperplasia .
In 10-15% of women held therapy with ulipristala It was observed growth of the endometrium Which reached a thickening 16 mm. This thickening also independently disappears at the end of treatment and return to normal menstrual bleeding . If within 3 months after discontinuation of the drug, thickening of the endometrium does not come to the state standards, it is necessary to pass an additional examination in order to exclude or confirm other pathologies.
Ulipristal induces apoptosis and oppresses cell proliferation Thereby providing a direct effect on leiomyoma Leading to their reduction.
The daily intake of 5 mg ulipristala It leads to the guaranteed inhibition of ovulation the majority of women receiving it, confirming the maintenance of the level of progesterone at 0, 3 ng / ml. Also, a daily intake of a given dose of the drug is partially reduced the concentration of FSH While leaving the content in the blood plasma Estradiol at the secondary level the follicular phase .
During the 3-month treatment ulipristal It has no effect on the amount of plasma ACTH . prolactin . thyroxine binding globulin .
In preclinical animal studies, while taking multiple doses, there was no threat Toxicity and genotoxicity Products for Human Use. It was noted that the death of fetuses animals when receiving doses greater than 1 mg / kg, and therefore, is not installed Safety ulipristala towards human embryos . In small doses, which allows you to keep a pregnancy in animals, teratogenic action was not observed. Also, according to the findings of these studies, there is no direct evidence of the effect of the drug on reproductive ability animals and their offspring.
Clinical studies of safety and efficacy Esmii at daily doses of 5 and 10 mg, were conducted on volunteers with a female menstrual bleeding severe, provoked uterine myoma . Compared with the group placebo It was noted clinically significant decrease in the volume of blood loss Related menstruation , In patients receiving ulipristal , Which allows for faster effective correction of anemia Than when applied alone iron supplementation . Patients receiving group ulipristala , Lowering the amount of blood loss was comparable with the group of patients treated with Leuprorelin (GnRH agonist). In most cases resulted in a reception Esmii cessation of bleeding during the first week of treatment (developing amenorrhea ). MRI studies in this group showed a significant a decrease uterine fibroids As compared with the group placebo . Carrying US control at the end of treatment (Week 13), in order to establish reduce the size of uterine fibroids It showed preservation of its parameters in a group ulipristala for 25 weeks, compared with some increase in its dimensions in the group Leuprolide .
Upon receiving ulipristala in a single dose of 5 mg, a rapid absorption of the drug from reaching Cmax after 60 minutes at - 23 ± 5 14, 2 ng / ml plasma concentrations of 61, 3 31 ± 7 ng / ml. Ulipristal undergoes rapid transformation with the release pharmacologically active metabolite While after 60 minutes reached Cmax 4 9 ± 4 ng / ml and a plasma concentration of 26 ± 12 ng / ml.
When receiving 30 mg Esmii during breakfast high in fat, 45% reduction was observed Cmax, up to 3 hours and an increase in Tmax 25% increase in plasma concentrations, both the ulipristala And its metabolite Unlike fasting. With daily pill, this effect is not regarded as significant.
The plasma protein ulipristal It binds to 98% or even more.
Metabolism takes place with the participation of cytochrome P450 with the final selection di-N-demethylated metabolite .
