Medicine of Esmiya (Esmya) is issued in the form of tablets at which one party there is an engraving of "ES5". One packaging can contain 28 or 84 tablets.

Pharmacodynamics and pharmacokinetics

Esmiya's (Esmya) drug contains substance — ulipristat a synthetic origin, being the selection modulator of progesteronovy receptors and differing in tkanespetsifichny selective antiprogesteronovy action.

Ulipristal is characterized by direct impact on an endometria. At most of women, at use of 5 mg of drug daily throughout a menstrual cycle including having myoma, there does not come the menstrual bleeding, subsequent to this cycle. At the termination of reception of tablets, the menstrual cycle is, as a rule, recovered for a month.

Direct impact of drug on an endometria is connected with some of its specific changes characteristic of this class of medicines and provoked by antagonistic action to progesteronovy receptors. At 60% of the women accepting ulipristat for 3 months, histologic changes are shown by poorly proliferating inactive epithelium with the accompanying asymmetry of its growth and growth of a stroma, and also cystous expansion of glands with progestagenny and oestrogenic impacts on an epithelium. These changes have reversible character with disappearance on the termination of a course of treatment and have no relation to  an endometria hyperplasia.

At 10–15% of the women passing therapy using an ulipristal growth of an endometria which reached a thickening more than 16 mm was observed. This thickening also independently disappears on the end of treatment and return of normal menstrual bleedings. If for 3 months after drug withdrawal, the thickening of an endometria does not come to a condition of norm, it is necessary to pass additional inspections for the purpose of an exception or confirmation of other pathologies.

Ulipristal induces apoptosis and oppresses cellular proliferation, thereby making the direct impact on leiomyomas leading to their reduction.

Daily reception of 5 mg of an ulipristal leads to the guaranteed oppression of an ovulation at most of the women accepting it that confirms maintenance of level of content of progesterone on a mark of 0,3 ng/ml. Also, daily reception of this dose of drug partially reduces concentration of FSG, at the same time leaving contents in an oestradiol blood plasma  at the level of an average follicular phase.

During 3-month therapy ulipristat does not exert impact on quantity in a blood plasma of AKTG, prolactin, tiroksinsvyazyvayushchy globulin.

In the conducted preclinical trials on animals, at reception of repeated doses, threat of toxicity and genotoxicity of drug for the person was not revealed. The death of fruits of animals at reception of doses was noted more than 1 mg/kg in this connection, safety of an ulipristal in relation to an embryo of the person is not established. In small doses which allowed to keep pregnancy at animals teratogenic action was not observed. Also, on data outputs of researches, there are no direct proofs of influence of drug on reproductive ability of animals and their posterity.

Clinical trials of safety and Esmiya's efficiency in daily doses of 5 and 10 mg, were carried out on female volunteers with the menstrual bleedings of difficult character provoked by a hysteromyoma. In comparison with group of placebo clinically significant decrease in volume of the blood loss connected with periods was noted, at the patients receiving ulipristat that allowed to carry out faster effective correction of anemia, than at use of one iron preparations. At patients of group of reception of an ulipristal, lowering of volume of blood loss, was comparable to group of patients accepting Leyprorelin (GNRG agonist). In most cases Esmiya's reception led to the termination of bleeding for the first week of treatment (the amenorrhea developed). Researches MRT in this group, were shown by considerable reduction of a hysteromyoma, in comparison with group of placebo. Carrying out ultrasonography control on the termination of a course of treatment (the 13th week), for the purpose of establishment of decrease in the sizes of a hysteromyoma, showed preservation of its parameters in group of an ulipristal within 25 weeks, in comparison with some increase in its sizes in Leyprorelin's group.

After reception of an ulipristal in a single dose of 5 mg, there is a fast absorption of drug, to achievement of Cmax in 60 minutes at the level — 23,5±14,2 ng/ml and plasma concentration of 61,3±31,7 ng/ml. Ulipristal is exposed to fast transformation with allocation pharmacological of an active metabolite, at the same time in 60 minutes Cmax in 9±4,4 ng/ml and plasma concentration of 26±12 ng/ml is reached.

At reception of 30 mg of Esmiya during a breakfast with a large amount of fats, lowering of Cmax, till 3 o'clock increase in Tmax and 25% increase of plasma concentration, both the ulipristal, and its metabolite, unlike reception on an empty stomach observed 45%. At daily reception of tablets this effect is not considered as significant.

With proteins of plasma ulipristat communicates for 98% and even more.

The metabolism occurs with the participation of P450 cytochrome about allocation final di-N-demetilirovannogo metabolites.

It is more removed by intestines, in smaller (about 10%) kidneys. T1/2 in a dose of 5 mg, about 38 hours, with average clearance about 100 l/h.

Esmiya, application instruction

The instruction recommends one-time daily reception of the 1st tablet for Esmiya orally (inside), in independence of food.

Time of the beginning of therapy is limited first week of a menstrual cycle. During this period it is necessary to begin to take Esmiya's pill, it is desirable at the same time days.

At the admission of time of reception of the next tablet, it is necessary to accept it as soon as possible, for 12 hours. In case of exceeding of this limit of time, miss this reception and continue a course of treatment from the subsequent tablet in due time.

Because of lack of experience of use of Esmiya throughout time exceeding 3 months, this term is the only thing admissible for therapy.

Overdose

Full data on a possibility of overdose by Esmiya's drug and the subsequent to it negative manifestations, for this time do not exist. It is thoroughly known that reception of single 200 mg of a dose of drug and daily 50 mg of a dose, within 10 days, did not lead to serious or serious conditions of the patient.

Interaction

Hormonal contraceptive drugs, also as well as Esmiya influence progesteronovy receptors and can lower effects of each other in this connection, their combined use is not recommended.

The combined Esmiya's reception and inhibitors of an isoenzyme CYP3A4 moderate (Erythromycin) and powerful (Nefazodon, Ritonavir, Ketokonazol) actions, can provoke significant increase in plasma concentration of an ulipristal. For this reason their combined use is not recommended. Reception of inhibitors of an isoenzyme of CYP3A4 of weak action significantly does not influence Esmiya's pharmacokinetics in this connection, does not demand correction of a dose of the last.

Reception of inductors of an isoenzyme of CYP3A4, leads to lowering of plasma maintenance of an ulipristal. Therefore parallel use of inductors of an isoenzyme of CYP3A4 of powerful action (The rifampicin, Phenytoinum, Carbamazepine, means including the St. John's Wort which is made a hole) is not recommended.

During absorption in walls of a gastrointestinal tract ulipristat it is capable to inhibit P-gp, thereby increasing plasma concentration of P-gp substrates. In this regard joint appointment of Esmiya and P-gp substrates is not recommended (Digoxin, Dabigatran).

Further the clinical use of Esmiya can reveal other interactions of medicines.
