5. Farmacological properties

5.1. Farmacodynamic properties

Pharmacotherapeutic group: antioxidant.
ATX Code: N07XX.

The mechanism of action
Mexol® action mechanism is due to its antihyplance, antioxidant and membraneoprotective effects. It inhibits the processes of lipid peroxidation, increases the activity of superoxidsmutase, increases the ratio of lipid beam, reduces the viscosity of the membrane, and increases its fluidity. The activity of membrane enzymes (calcium-dependent phosphodesturas, adenilatcyclase, acetylcholinesturaz), receptor complexes (benzodiazepin, gamma-aminobatic acid (GABA), acetylcholine), which enhances their ability to bind the structural and functional organization of biomemubin, is modulating manditors and improvement of synaptic programs. Mexidol® increases the content of dopamine in the brain. It causes an increase in the compensatory activity of aerobic glycolysis and a decrease in the degree of inhibition of oxidative processes in the Crebs cycle in conditions of hypoxia with an increase in the content of adenosine triphosphate (ATP), creatine phosphate and activation of energy synthetic functions of mitochondria, stabilization of cell membranes.

Pharmacodynamic effects
have antihypoxic, membrane, nootropic, anticonvulsant, anxiolytic effects, and increases the body's resistance to stress. The drug increases the resistance of the body to the effects of the main damaging factors, to oxygen -dependent pathological conditions (shock, hypoxia and ischemia, cerebrovascular impairment, alcohol intoxication and antipsychotic drugs (antipsychotics)). Stabilizes membrane structures of blood cells (red blood cells and platelets) for hemolysis.
Mexidol® improves brain metabolism and blood supply to the brain, improves microcirculation and rheological properties of blood, reduces platelet aggregation. It has a hypolipidemic effect, reduces the level of total cholesterol and low density lipoproteins (LDL).
Mexidol® normalizes metabolic processes in ischemized myocardium, reduces the necrosis zone, restores and improves the electrical activity and contractility of myocardium, and also increases coronary blood flow in the ischemia zone, reduces the consequences of reperfusion syndrome with acute coronary insufficiency. Increases the antianginal activity of nitrophe -prescription.
Mexidol® helps to preserve ganglion cells of the retina and optic nerve fibers with progressive neuropathy, the causes of which are chronic ischemia and hypoxia. Improves the functional activity of the retina and optic nerve, increasing visual acuity.
Reduces enzymatic toxemia and endogenous intoxication in acute pancreatitis.

The clinical efficiency and safety
randomized double-blind, a clanbo-controlled in parallel groups, the study of the efficiency and safety of the drug Mexidol® Phase III (Epica) with prolonged sequential therapy in patients with hemispheric ischemic strokes in acute and early recovery periods was carried out with the participation of 150 patients aged 40 up to 79 years. Patients were randomized in 2 groups: the first group received therapy with Mexidol® at 500 mg per day in/V for 10 days with the subsequent administration of 1 tablet (125 mg) 3 times a day for 8 weeks. The Mexidol® therapy group shows a significant decrease in symptoms and functional disorders compared to placebo. When using the drug Mexidol®, a reliably more pronounced improvement in vital functions was noted compared to placebo: at the time of the end of the therapy, the average score on the modified Rankin scale (MSHR) was lower in the Mexidol® (P = 0.04) drug; Also in this group there was a more pronounced dynamics of reducing the average score in MSHR (p = 0.023). The proportion of patients who have reached the recovery corresponding to 0-2 points for MSHR upon completion of therapy was reliably higher in the Mexidol® preparation group compared to placebo-59 (96.7 %) and 53 (84.1 %), respectively (p = 0.039). At the time of the end of the therapy, the neurological deficiency was reliably lower in the therapy group Mexidol®: when testing on a stroke scale of the National Institute for Health at the time of the end of therapy, the average value was lower in the therapy group Mexidol® (p = 0.035). The use of Mexidol® contributed to better functional recovery: the proportion of patients with the lack of problems with movement in space was significantly higher (p = 0.022). According to the results of subanalysis, the effectiveness of the drug Mexidol® for all the scales used was equal in all age groups. There were no reliable differences in the frequency of unwanted reactions in patients of both groups, the safety profile of prolonged consistent therapy with Mexidol® was comparable to placebo in patients of various age groups.
International multicenter randomized dual-blind-controlled study on evaluating the effectiveness and safety of sequential therapy with Mexidol® and Mexidol® Forter III (MEMO) in patients with chronic brain ischemia was carried out with the participation of 318 patients aged 40 to 90 years. Patients were randomized in 2 groups: the first group received the therapy with Mexidol® at 10 ml (500 mg) once a day in/in drip or intravenously slowly for 14 days with the subsequent reception of Mexidol® 1 tablet 3 times per 3 times per. day for the next 60 days. Based on the results of the study, at the time of completion of therapy, patients identified statistically significant changes in points on the Montreal scale of cognitive assessment (MOCA) when comparing the dynamics between groups of drugs Mexidol®/Mexidol® Forter 250 and placebo (p <0.000001, T-criteria for independent samples). The lower border of 95 % of the trust interval for the difference in the average main performance indicator in the groups of drugs Mexidol®/Mexidol® Fort 250 and the placebo was 1.51. This boundary is a positive value, which allows us to state the superior effectiveness of the drugs Mexidol® and Mexidol® Forte 250 above the placebo. Also, according to the results of the study, statistically significant changes in points on the Monual MOCA scale at the stage of completion of therapy by the patient were detected to compare the dynamics between groups of drugs Mexidol® and Mexidol® Forte 250 and placebo during subanalysis for all age groups, which indicates equal efficiency of Mexidol® preparations and Mexidol® Fort 250 in all age groups. Based on the results of the assessment of the secondary endpoints of the effectiveness of drugs Mexidol® and Mexidol® Fort 250 during therapy, statistically significant differences were obtained compared to the placebo according to the following indicators: the dynamics of the severity of cognitive disorders on the MOCA scale; the dynamics of the severity of cognitive disorders on the test of the replacement of digital characters; The dynamics of the severity of asthenic disorders on the asthenia scale MFI-20; the dynamics of autonomic changes according to the Wein questionnaire; dynamics of anxiety level on the Bek scale; The dynamics of motor changes on the Tinetti scale; The dynamics of the general clinical impression on the general clinical impression scale (The Clinical Global Impressions Scale); The dynamics of the quality of life of patients according to the SF-36 questionnaire (psychological component of health).
The results of a statistical analysis of the frequency of the occurrence of undesirable phenomena, laboratory analyzes, and physically examinations demonstrate the absence of significant differences between the compared groups by the main safety indicators, which indicates a comparable nature of the safety profiles of the studied drugs Mexidol® and Mexidol® Forte 250 and the placebo. When conducting subanalysis in patients of various age groups, the similar nature of the safety profiles of drugs Mexidol®+Mexidol® Forte 250 (ethylmethylhydroxypyridine succinate) and placebo was proved.

5.2. Pharmacokinetic properties

Absorption
