Description of pharmacological action:

The hepatoprotective effect of methadoxin is due to the membrane-stabilizing effect and is based on the ability to restore the ratio of saturated and unsaturated free fatty acids. As a result, increases the resistance of hepatocytes to the action of lipid peroxidation, which occurs when exposed to various toxic agents. Detoxification effect of methadoxin is due to the activation of liver enzymes involved in the metabolism of ethanol — alcohol dehydrogenase and acetaldehyde dehydrogenase, which accelerates the removal of ethanol and acetaldehyde from the body, and therefore reduces their toxic effects.

Metadoxine prevents the accumulation of triglycerides in hepatocytes, and also prevents the formation of fibronectin and collagen, which significantly slows down the process of formation of liver cirrhosis.

The drug reduces the mental and somatic manifestations of hangover, reduces the time of relief of withdrawal syndrome.

Metadoxin activates cholinergic and GABAergic neurotransmitter systems, improves the function of thinking and short memory, prevents the emergence of motor excitation, which is caused by ethanol.

Metadoxine has a non-specific antidepressant and anxiolytic effects, reduces the craving for alcohol.
