Summary:
Annotation. Chronic brain ischemia (Khim) is one of the most common in the clinical practice of neurological pathological conditions. The goal is to evaluate the effectiveness and safety of sequential therapy with Mexidol ^® intravenously and Mexidol ^® Fort 250 oral in groups of patients with arterial hypertension (AH) and without the aspect of the drug on cognitive functioning, as well as the severity of asthenic, anxiety, autonomic and motor disorders, and Quality of life in a chemical conditions. Material and methods. Within the framework of subanalysis, patients with chemicals were divided into 4 subgroups: 1st-patients with AH who received drugs Mexidol ^® and Mexidol ^® Forter 250 (n = 144); 2nd-patients with AG who received placebo (n = 146); 3rd-patients without hypertension receiving Mexidol ^® and Mexol ^® Fort 250 (n = 15); 4th-patients without hypertension receiving placebo (n = 12). Results. At the end of the observation period, statistically significant differences in the dynamics of the Mosa scale between groups of patients receiving Mexidol ^® and placebo (p = 0,000), indicating the superior effectiveness of the use of Mexidol in the subgroup of patients with AH, were identified. Against the background of therapy with Mexidol ^® , unlike placebo, the median value of the point on the Mosa scale at the end of the observation period reached the level of norm in all patients. When assessing the secondary endpoints of effectiveness, the statistically significant advantage of Mexidol over the placebo in the population of patients with AH at the final visit was achieved by the following parameters: a test of digital characters, an asthenication scale MFI-20, a Bek anxiety scale, a tinetti scale, and a psychological component of health according to the questionnaire according to the questionnaire SF-36. The comparable nature of the safety profile of Mexidol and placebo is established. Conclusion. The results give reason to recommend the long-term consistent use of the drug Mexidol ^® in the complex treatment of patients with hypertension as an instrument for protecting the brain as an organ-canal and means of pathogenetically substantiated therapy of cognitive, emotional, asthenic, vegetative and motor disorders.

Summary:
Annotation. Chronic brain ischemia (Khim) is one of the most common neurological pathologies. Its development is affected by many factors, among which arterial hypertension (AH) occupies a special place. Him contributes to cognitive impairment, negatively affects the quality of life and leads to motor and psycho -emotional disorders. In the aspect of the therapy of this condition, an important role belongs to neuroprotectors and, in particular, the use of ethylmethylhydroxypyridine of succinate (Mexol ^® , NPK Pharmasoft LLC, Russia), which has a multimodal effect and confirms its high efficiency in a large number of clinical studies. The evidence base of ethylmethylhydroxypyridine of the succinate, including in the study of Memo, indicates the particularly high effectiveness of the drug among patients with Khim and AG: they have Mexol ^® significantly improves cognitive functions, reduces the level of anxiety and asthenia and improves the quality of life. With this in mind, the drug can be recommended for use in complex therapy of chemicals, especially in patients with AG. Keywords: chronic brain ischemia, ethylmethylhydroxypyridine succinate, Mexidol ^® , arterial hypertension, cognitive functions.

Summary
is the purpose of the study. To evaluate the effectiveness of consistent therapy with Mexidol and Mexidol Fort 250 compared to placebo in patients with chronic brain ischemia (chemical) of different age -related subgroups. Material and methods. Subanalis of data of an international multicenter randomized double-centered placebo-controlled study of Memo, in which 318 patients (25% of men) aged 40 to 90 (median 60) years participated. The effectiveness of treatment was estimated in three age groups: 40-60 (n = 163), 61–75 (n = 141) and 76–90 (n = 13) years. As the primary final point of efficiency, the axis considered the increase in the dynamics of the amount of points on the MOCA scale in the form of an absolute difference between the amount of points before the start of treatment and on the 75th day of therapy. As a secondary endpoint of efficiency, the speaker was considered by the amount of points on the following questionnaires and scales: a test of digital symbol replacements, a questionnaire for the quality of life of the SF-36, a scale of subjective assessment of asthenia MFI-20, a Vein vegetative impaired questionnaire, a Bek anxiety scale, a thinetti motor activity scale.

Results.

The positive dynamics of the severity of cognitive, emotional and motor disorders in groups 40-60 and 61–75 years after 75 days of therapy was detected in patients who received both Mexidol and placebo, however, in patients receiving Mexidol, these changes turned out to be more pronounced, which indicate the higher values ​​of the absolute difference in the amount of the points of the studied indicators.

Conclusion.

The results of the study have shown that in patients with Khim, a significant improvement in cognitive and motor functions, improving the quality of life, a decrease in the severity of autonomic disorders, asthenia
and anxiety after 75 days of therapy were observed against the background of the use of Mexido compared to placebo. The
results indicate the appropriateness of the use of Mexidol for the treatment of patients of different ages with chemicals.

Summary:
in a review article, modern approaches to testing and registration of reproduced (generic) drugs are considered. The history of the formation of a methodology for research of reproduced drugs and modern legislation of the Russian Federation is presented. The stages of confirmation of the equivalence of original and reproduced drugs are described: pharmaceutical equivalence, bioequivalence and therapeutic equivalence. Methods of evaluating bioequivalence as a basic study in the registration of reproduced drugs are analyzed in detail. On the example of the original domestic neuroprotector of the drug Mexidol (ethylmethylhydroxypyrididine of succinate) and its generiks described how legislative acts are implemented in practice. It is concluded that not all reproduced drugs can be interchangeable with the original drug.

Summary:
The review discusses the interchangeability of drugs (drugs), approaches to registering original and reproduced drugs and types of equivalence, as well as problems with generics in clinical practice. The results of pharmacoepidemiological studies, widely leading in recent years, indicate an insufficient study of the influence of reproduced drugs on remote outcomes of chronic diseases, including mortality. The long-term economic prospect of the use of reproduced drugs remains unclear. The main reasons for the difference between the original and reproduced drugs include differences in the methods of synthesis of active substances, as well as as part of auxiliary substances and impurities. Comparative studies of the therapeutic equivalence of generics with the original and are carried out quite rarely and often suffer from methodological disadvantages, which does not guarantee comparable efficiency and safety of such drugs. In this regard, the automatic replacement of drugs containing the same active substance, without the participation of the attending physician, should be avoided.

Keywords: generics; bioequivalence; pharmaceutical equivalence; therapeutic equivalence; interchangeability.

Summary:
Purpose of the study. Conduct a pharmacoeconomic analysis of the most frequently prescribed drugs of a group of neuroprotectors for the treatment of patients with an ischemic stroke (AI) of a mild and early recovery period in the Russian Federation. Material and methods. Three medical technologies were compared: ethylmethylhydroxypirinate (drug - LP - Mexidol), Inosin + nicotinamide + riboflavin + amber acid (LP cytoflavin) and disordered hemoderivat of blood calves (LP Actovegin). Based on the results of an indirect comparison, a pharmacoeconomic analysis was carried out through the following methods: analysis of cost minimization, analysis of “influence on the budget” and sensitivity analysis. Results. Analysis of effectiveness showed that the LP studied have equal efficiency: the difference of the average LP Aktovegin is 0.2 (di min 0.18; max 0.22), Mexol Mexidol LP (confidence interval - di - min 0.25; Max; 0.65), LP cytoflavin - 0.61 (di min 0.23; max 0.99). Analysis of the minimization of costs showed that the cost of a course of the treatment of one patient of the LP Mexol is accompanied by the lowest costs, while saving is observed when assessing both the total costs and individual components: a solution for injection and tablet forms. The savings in comparison with the LP Cytoflavin and LP Aktovegin is 231 rubles. and 12,872 rubles. respectively. It is possible to additionally treat 5 patients with AI Mexidol on saved only from one course. Moreover, the oral therapy of the Mexol Mexidol LP is more economical by 164 rubles. and 3481 rub. Therapies with similar dosage forms of the Cytoflavin and Actoveginal Public Use, which is an advantage for the population in treatment at the outpatient stage. An analysis of the impact on the budget showed that the total costs of the current distribution of patients according to treatment schemes are 1.99 billion rubles. With an increase in the share of patients receiving Mexidol LP, 10% of the total costs will amount to 1.75 billion rubles, which is 240 million rubles. Less current. On saved products, 85 thousand patients with AI can be additionally treated. A two -factor analysis of sensitivity showed that the result of the analysis of minimization of costs and the impact on the budget remains stable when the number of patients and the cost of 1 mg of Mexidol LP per amount from -10% to +10% changes. Conclusion. In the course of the indirect comparison, it was found that the LP Mexidol, the LP Cytoflavin and LP Actovegin are equal in terms of effectiveness. However, the Mexidol LP has an advantage from the point of view of analyzing the minimization of costs: there are enough funds saved from one course to treat 5 patients with II Mexidol. When considering the consequences of increasing the share of patients receiving Mexol's LP, data were also obtained indicating the savings of funds, which allows us to consider the therapy of the LP Mexoli -preserving budget -storage in the treatment of Easy degree in the Russian Federation. Key words: pharmacoeconomics, indirect comparison, analysis of cost minimization, analysis of “influence on the budget”, neuroprotectors, ischemic stroke.

Summary:
in the viewing article, a modern concept of mechanisms of antioxidant and antihypoxic effects of the original domestic drug Mexidol (2-ethyl-6-methyl-3-hydroxypirinate) is presented. The direct antioxidant activity of Mexidol is described, which consists in the ability of the drug to inactivate free radicals and increase the activity of antioxidant enzymes of glutathioneperoxidase and in vitro superoxidism. The data on the presence of an indirect antioxidant activity in the Mexidol, manifested in an increase in expression in conditions of ischemia of the transcription factor NRF2, which is responsible for the development of cell stability to oxidative stress. The anti -human action of Mexidol is discussed, due to the presence of amber acid in its molecule, which, on the one hand, maintains the operation of the serpentinexidate link in the Krebs cycle under conditions of oxygen, and on the other hand, is associated with its specific receptors (GPR91) and triggers a cascade of biochemical reactions that increase the resistance of the resistance organism to a lack of oxygen. Keywords: Mexidol, ethylmethylhydroxypirinate, antioxidant, antihypoxant.

Summary:
Purpose of the study. To evaluate the effectiveness and safety of prolonged sequential therapy with Mexidol with patients with hemispherical ischemic stroke (AI) in acute and early recovery periods. Material and methods. 151 patients (62 men and 89 women) were included in the randomized double-centered placebo-controlled multicenter placebo-controlled in parallel research groups, 150 patients (62 men and 88 women) aged 40 to 79 years are randomized. Patients by simple randomization were distributed to 2 groups: patients of the 1st group received therapy with Mexidol of 500 mg/day intravenously for 10 days, followed by 1 tablet (125 mg) 3 times a day for 8 weeks. Patients of the 2nd group received a placebo according to a similar scheme. The duration of participation in the study was from 67 to 71 days. Results. At the time of the end of the therapy, the average score on the modified scale of Rankin (MSHR) was lower in the 1st group than in the 2nd (p = 0.04). The dynamics of reducing the average score according to MSHR (1-5th visit) was more pronounced in the 1st group (p = 0.023). The proportion of patients who have reached the recovery corresponding to 0-2 points in MSHR (5th visit) was significantly higher in the 1st group (p = 0.039). When testing on a stroke scale of the National Institute for Health to the 5th visit, the average value was lower in the 1st group (p = 0.035). A decrease in the score on the stroke scale of the National Institute for Health at the time of the end of the course of therapy regarding the initial level in patients with diabetes was more pronounced in the 1st group (p = 0.038). In the 1st group in the general population of patients and subpopulation of patients with diabetes, the dynamics of improving the quality of life was more pronounced and was observed from the 2nd visit. The proportion of patients with the lack of problems in space was significantly higher in the 1st group (p = 0.022). There were no reliable differences in the frequency of unwanted phenomena in patients of both groups. Conclusion. It is recommended that the use of Mexidol in the acute and early recovery periods of AI is recommended.
