Pharmacological Action

Anti-alcoholic, hepatoprotective and detoxifying agent, a derivative of pyridoxine (vitamin B₆). It accelerates the elimination of ethanol and acetaldehyde from the body and activates enzymes involved in ethanol metabolism.

It restores the ratio of saturated and unsaturated free fatty acids in plasma and prevents primary structural degeneration of hepatocytes; it inhibits the formation of fibronectin and collagen, preventing the development of liver fibrosis and cirrhosis.

It reduces the pathological craving for ethanol, decreases the severity of mental and somatic symptoms of hangover, and reduces the time for relief of alcohol withdrawal syndrome.

It normalizes the detoxification function of the liver, improves the mental state of patients, and causes regression of depressive symptoms. It creates conditions for obtaining favorable results when conducting psychocorrective setting to change the alcoholic stereotype.
