Mexidol®

Mexidol®

Mexidol® is effective in treatment of acute and chronic diseases caused by ischemia and hypoxia of different genesis. Today Mexidol® is one of the main means of basic anti-ischemic therapy in Russian clinics, owing to the universal mechanism of action and a wide range of pharmacological effects.



Active substance:

Ethylmethylhydroxypyridine succinate

Pharmachologic effect:


Mexidol® is an inhibitor of free radical processes, membrane protector with antihypoxic, stress-protective, nootropic, anticonvulsant and anxiolytic effects.
Mexidol® increases the body's resistance to the various damaging factors (shock, hypoxia and ischemia, cerebral circulation disorders, alcohol intoxication and antipsychotic drugs - neuroleptics).
The mechanism of action of Mexidol® is due to its antioxidant, antihypoxant and membrane-protective action. 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 PDE, adenylate cyclase, acetylcholinesterase), receptor complexes (benzodiazepine, GABA, acetylcholine), which enhances their ability to bind to ligands, contributes to the preservation of the structural and functional organization of biomembranes and transport of neuromembranes.
Mexidol® increases the content of dopamine 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 conditions of 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.
Mexidol® 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 (erythrocytes and platelets) during hemolysis. Has a hypolipidemic effect, reduces the content of total cholesterol and LDL.
The antistress effect 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 structures of the brain.
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 relieve cognitive impairment caused by long-term ethanol intake and its cancellation.
Under the influence of Mexidol®, the effect of tranquilizing, neuroleptic, antidepressant, hypnotic and anticonvulsant drugs is enhanced, which makes it possible to reduce their doses and reduce side effects.
Mexidol® improves the functional state of the ischemic myocardium. In conditions of coronary insufficiency, it increases collateral blood supply to the ischemic myocardium, contributes to the preservation of the integrity of cardiomyocytes and the maintenance of their functional activity. Effectively restores myocardial contractility in reversible cardiac dysfunction.

Pharmacokinetics:


Mexidol® is rapidly absorbed when taken orally.
When taken orally in doses of 400-500 mg, Cmax is 3.5-4 mcg / ml. It is quickly distributed in organs and tissues. The average retention time of the drug in the body when taken orally is 4.9-5.2 hours.
When administered intramuscularly, the drug is determined in blood plasma for 4 hours after administration. Tmax - 0.45–0.5 hours. Cmax when administered in doses of 400–500 mg is 3.5–4 μg / ml.
Mexidol® quickly passes from the bloodstream to organs and tissues and is quickly eliminated from the body. The retention time of the drug is 0.7-1.3 hours.

Mexidol® is metabolized in the liver by glucuron conjugation. 5 metabolites have been identified: 3-hydroxypyridine phosphate - is formed in the liver and, with the participation of alkaline phosphatase, decomposes into phosphoric acid and 3-hydroxypyridine; 2nd metabolite - pharmacologically active, is formed in large quantities and is found in urine on the 1st or 2nd day after administration; 3rd - excreted in large quantities in the urine; 4th and 5th - glucuron conjugates.

T1/2 when taken orally is 2–2.6 hours. It is quickly excreted in the urine, mainly in the form of metabolites and in small amounts unchanged. It is most intensively excreted during the first 4 hours after taking the drug. The indicators of excretion in the urine of unchanged drug and metabolites have individual variability.
