Pharmacological action is determined by the properties of the vitamins that make up the drug.
Thiamine (vitamin B1) in the human body, as a result of phosphorylation processes, it turns into cocarboxylase, which is the coenzyme of many enzyme reactions. Thiamine plays an important role in the carbohydrate, protein and fat metabolism. Actively participates in the processes of carrying out nervous excitation in the synapses.
Pyridoxine (vitamin B6) necessary for normal operation central and peripheral nervous system. In the phosphorylated form is a coenzyme in the metabolism of amino acids (decarboxylation, reamination, etc.). Acts as a coenzyme of the most important enzymes that act in the nerve tissues. Participates in the biosynthesis of many neurotransmitters - such as dopamine, norepinephrine, epinephrine, histamine and gamma-aminobutyric acid.
Cyanocobalamin (vitamin B12) is necessary for normal hematopoiesis and ripening of erythrocytes, and also participates in a number of biochemical reactions that ensure the vital activity of the organism - in the transfer of methyl groups, in the synthesis of nucleic acids, protein, in the exchange of amino acids, carbohydrates, lipids. Has a beneficial effect on the processes in the nervous system (the synthesis of nucleic acids and the lipid composition of cerebrosides and phospholipids). Coenzyme forms of cyanocobalamin - methylcobalamin and adenosylcobalamin are necessary for replication and cell growth.
