Pharmacological properties

Pharmacodynamics

Vitamin B ₆ (pyridoxine) takes part in the metabolism; it is important for the functioning of the central and peripheral nervous system.

It is part of the enzymes that transaminate and decarboxylate amino acids. When it enters the body, pyridoxine is phosphorylated, turning into pyridoxal-5-phosphate. It takes part in the metabolism of cysteine, methionine, tryptophan, glutamic and other amino acids, and also plays an important role in the metabolism of histamine. Promotes the normalization of lipid metabolism, increases diuresis and enhances the effect of diuretics.

An isolated deficiency of pyridoxine is observed in very rare cases, mainly in children who are on special artificial nutrition. It manifests itself in the form of diarrhea, seizures, anemia, and the development of peripheral neuropathy is also possible.

Pharmacokinetics

Pyridoxine is rapidly absorbed throughout the small intestine, more of it is absorbed in the jejunum.

Metabolism occurs in the liver with the formation of two pharmacologically active metabolites - pyridoxamine phosphate and pyridoxal phosphate. Pyridoxal phosphate binds to plasma proteins by 90%. Penetrates well into all tissues; accumulates mainly in the liver, to a lesser extent in the central nervous system and muscles.

It crosses the placenta and is secreted in breast milk. T _1/2 (half-life) ranges from 15 to 20 days. It is excreted by the kidneys, as well as during hemodialysis.
