5. Pharmacological properties
5.1 Pharmacodynamics:
Pharmacotherapeutic group: antioxidant agent.
ATX Code: N07XX.
The pharmacological action
of Mexidol is due to its antihypoxant, antioxidant and membrane-protective action. It inhibits lipid peroxidation processes, increases superoxide dismutase activity, increases the lipid-protein ratio, reduces membrane viscosity and increases membrane fluidity. The drug modulates the activity of membrane-bound enzymes (calcium-independent phosphodiesterase, adenylate cyclase, acetylcholinesterase), receptor complexes (benzodiazepine, gamma-aminobutyric acid (GABA), acetylcholine), which enhances their ability to bind to ligands, helps to preserve the structural and functional organization of biomembranes, transport neurotransmitters and improve synaptic transmission. Mexidol® increases the content of dopamine in the brain. It causes enhancement of compensatory activity of aerobic glycolysis and reduction of the inhibition rate of oxidative processes in the Krebs cycle under hypoxia with an increased content of adenosine triphosphate (ATP), creatine phosphate and activation of energy-synthesizing functions of mitochondria, as well as promotes stabilization of cell membranes.
Pharmacodynamic effects
The drug has an antihypoxic, membrane-protective, nootropic, anticonvulsant, anxiolytic effect, and increases the body’s resistance to stress. The drug increases the body’s resistance to major damaging factors and oxygen-dependent pathological conditions (shock, hypoxia and ischemia, impaired cerebral circulation, intoxication with alcohol and antipsychotic agents (neuroleptics)). It stabilizes membrane structures of blood cells (erythrocytes and platelets) in hemolysis.
Mexidol® improves cerebral metabolism and blood supply to the brain, improves microcirculation and rheological properties of blood, and reduces platelet aggregation. It has a hypolipidemic effect, reduces the levels of total cholesterol and low-density lipoproteins (LDLs).
Mexidol® normalizes metabolic processes in ischemic myocardium, reduces the necrosis area, restores and improves myocardial electrical activity and contractility, as well as increases coronary blood flow in the ischemia area and mitigates the consequences of reperfusion syndrome in acute coronary insufficiency. It increases antianginal activity of nitrates.
Mexidol® promotes preservation of retinal ganglion cells and optic nerve fibers in progressive neuropathy caused by chronic ischemia and hypoxia. It improves the functional activity of the retina and optic nerve, and increases the visual acuity.
The drug reduces enzymatic toxemia and endogenous intoxication in patients with acute pancreatitis.
The clinical performance and safety
A randomized double-blind placebo-controlled parallel-group study of efficacy and safety of Mexidol® in phase III (EPICA) in long-term sequential therapy in patients with hemispheric ischemic stroke in the acute and early recovery periods involved 150 patients aged 40 to 79. The patients were randomized into 2 groups: the first group was treated with Mexidol® 500 mg daily by IV drop infusion for 10 days followed by 1 tablet (125 mg) 3 times a day for 8 weeks. The Mexidol® group showed a significant reduction of symptoms and functional disorders, as compared with the placebo group. Mexidol® administration led to significantly more pronounced improvement of vital activity in comparison with the placebo: the average score on the Modified Rankin Scale (mRS) at the end of therapy was lower in the Mexidol® group (p = 0,04). Furthermore, this group demonstrated more pronounced dynamics of decrease in the mRS average score (p = 0.023). The proportion of the patients who achieved recovery corresponding to 0-2 points on the mRS at the end of therapy was significantly higher in the Mexidol® group in comparison with the placebo group: 59 (96,7%) and 53 (84,1%), respectively (p = 0.039). The neurological deficit at the end of therapy was significantly lower in the Mexidol® group: the testing according to the National Institute of Health Stroke Scale showed that the mean value at the end of therapy was lower in the Mexidol® group (p = 0.035). The use of Mexidol® contributed to better functional recovery: the proportion of the patients with no spatial mobility issues was significantly higher (p = 0.022). According to the subanalysis results, the efficacy of Mexidol® on all of the scales used was identical in all of the age groups. There were no significant differences in the frequency of adverse reactions in the patients of both groups, and the safety profile of long-term sequential therapy with Mexidol® was comparable to that of the placebo in the patients of different age groups.
An international multicenter randomized double-blind placebo-controlled study to evaluate the efficacy and safety of sequential therapy with Mexidol® and Mexidol® FORTE 250 in phase III (MEMO) in patients with chronic cerebral ischemia involved 318 patients aged from 40 to 90. The patients were randomized into 2 groups: the first group was treated with Mexidol® 10 ml (500 mg) daily by IV drop or stream infusion slowly for 14 days followed by Mexidol® FORTE 250 1 tablet 3 times a day for the next 60 days. According to the results of the study, statistically significant changes in scores on the Montreal Cognitive Assessment Scale (MoCA) were detected at the end of therapy when comparing the progress between the groups of Mexidol®/Mexidol® FORTE 250 and the placebo (p < 0.000001, t-test for independent samples). The lower boundary of the 95% confidence interval for the mean difference of the main efficacy index between the groups of Mexidol®/Mexidol® FORTE 250 and the placebo was 1.51. This boundary is a positive value, indicative of the superior efficacy of Mexidol® and Mexidol® FORTE 250 over the placebo. Moreover, the results of the study revealed statistically significant changes of the MoCa scores at the end of therapy by the patient for the purpose of comparison of the progress between the groups of Mexidol® and Mexidol® FORTE 250 and placebo in the subanalysis for all of the age groups, which indicates equal efficacy of Mexidol® and Mexidol® FORTE 250 in all of the age groups. According to the results of evaluating secondary endpoints of efficacy of Mexidol® and Mexidol® FORTE 250 during the therapy, statistically significant differences between the drug groups and the placebo group were obtained for the following indicators: changes in cognitive impairment severity over time on the MoCA scale; changes in cognitive impairment severity over time according to the digit symbol substitution test; changes in asthenic disorders severity over time according to the Multidimensional Fatigue Inventory MFI-20; vegetative changes over time according to the Vein’s Questionnaire; changes in the anxiety level over time according to the Beck Depression Inventory; motor changes over time according to the Tinetti test; changes in the general clinical impression over time using the Clinical Global Impressions Scale; changes in the patients’ quality of life according to the Short Form (36) Health Survey questionnaire (psychological component of health).
The results of the statistical analysis of the adverse events frequency as well as the results of laboratory tests and physical examination demonstrate the absence of significant differences between the compared groups in terms of the primary safety endpoints, which is indicative of the comparable nature of the safety profiles of Mexidol® and Mexidol® FORTE 250 and the placebo. The subanalysis performed in patients of different age groups confirmed the similar nature of safety profiles of Mexidol®+Mexidol® FORTE 250 (ethylmethylhydroxypyridine succinate) and the placebo.

1. Composition and intended use of Mexidol®
Mexidol® contains the active ingredient ethylmethylhydroxypyridine succinate that belongs to the class of antioxidants. Antioxidants inhibit oxidative processes that occur in various disorders of the nervous and cardiovascular systems, as well as in cases of alcohol and drug intoxication.
Indications
Mexidol® is indicated for use in adults over 18 years of age for:
- acute cerebral circulation disorders;
- traumatic brain injury and consequences of traumatic brain injury;
- dyscirculatory encephalopathy (brain dysfunction caused by impaired blood circulation);
- chronic cerebral ischemia (impaired blood flow to the brain);
- dysautonomia syndrome (a condition caused by dysfunction of the nerves controlling the functions of internal organs);
- mild to moderate cognitive impairments (defective memory, attention, and mental performance);
- anxiety disorders in neurotic and neurosis-like states;
- acute myocardial infarction (from the first day) as part of complex therapy;
- primary open-angle glaucoma (elevated intraocular pressure) of various stages as part of complex therapy;
