Pharmacological action
Mexidol ® is an inhibitor of free radical processes, a membrane protector with antihypoxic, stress-protective, nootropic, anticonvulsant and anxiolytic effects. The drug increases the body’s resistance to the effects of various damaging factors (shock, hypoxia and ischemia, cerebrovascular accident, intoxication with alcohol and antipsychotics (antipsychotics)).
The mechanism of action of Mexidol ® is due to its antioxidant, antihypoxic and membrane protective effect. It inhibits lipid peroxidation, increases the activity of superoxide dismutase, increases the lipid-protein ratio, reduces the viscosity of the membrane, and increases its fluidity. Mexidol ® modulates the activity of membrane-bound enzymes (calcium independent phosphodiesterase, adenylate cyclase, acetylcholinesterase), receptor complexes (benzodiazepine, GABA, acetylcholine), which enhances their ability to bind to ligands, helps preserve the structural and functional organization of biomembranes, neurotransmitter transport and improved synaptic transmission.
Mexidol ® boosts dopamine levels in the brain. It causes an increase in the compensatory activation of aerobic glycolysis and a decrease in the degree of inhibition of oxidative processes in the Krebs cycle under hypoxia with an increase in the content of ATP and creatine phosphate, activation of the energy-synthesizing functions of mitochondria, and stabilization of cell membranes.
The drug improves metabolism and blood supply to the brain, improves microcirculation and rheological properties of blood, reduces platelet aggregation. It stabilizes the membrane structures of blood cells (red blood cells and platelets) during hemolysis. It has a lipid-lowering effect, reduces the content of total cholesterol and low density lipoproteins.
Antistress action is manifested in the normalization of post-stress behavior, somatovegetative disorders, restoration of sleep-wakefulness cycles, impaired learning and memory processes, reduction of dystrophic and morphological changes in various brain structures.
Mexidol ® has a pronounced antitoxic effect in withdrawal symptoms. It eliminates the neurological and neurotoxic manifestations of acute alcohol intoxication, restores behavioral disorders, autonomic functions, and is also able to remove cognitive impairment caused by prolonged intake of ethanol and its cancellation. Under the influence of Mexidol ®, the effect of tranquilizing, antipsychotic, antidepressant, hypnotics and anticonvulsants is enhanced, which allows to reduce their doses and reduce side effects. Mexidol ® improves the functional state of the ischemic myocardium. In conditions of coronary insufficiency, it increases the collateral blood supply to the ischemic myocardium, helps to preserve the integrity of cardiomyocytes and maintain their functional activity. Effectively restores myocardial contractility with reversible cardiac dysfunction.
