Pharmachologic effect. Vitamin B6 (pyridoxine) regulates protein metabolism. This is due to his participation in the processes of transport of amino acids across cell membranes. Pyridoxine increases the content of creatinine in the striated musculature, which plays an important role in the process of muscle contraction. Takes part in fat and lipid metabolism, improves the absorption of unsaturated fatty acids. With a deficiency of vitamin B6 (pyridoxine), the activity of glucose-6-phosphate dehydrogenase, one of the direct oxidation enzymes of glucose in the pentose-phosphate cycle, decreases. Pyridoxal-5-phosphate is part of the phosphorylase that regulates the breakdown of glycogen. Significantly affects blood formation and immunity. Vitamin B6 (pyridoxine) synthesizes erythropoiesis, leukopoiesis and hemoglobin biosynthesis; activates cellular factors of nonspecific immunological

Isonicotine hydrazide, penicillamine, cycloserine, and estrogen-containing oral contraceptives reduce the effects of pyridoxine. It is well combined with cardiac glycosides (pyridoxine enhances the synthesis of contractile proteins in the myocardium), with glutamic acid and asparkam (increased resistance to hypoxia). Pharmaceutically incompatible with vitamins B1 and B12, in powder with ascorbic and nicotinic acids.
Storage conditions. Vitamin B6 (pyridoxine) should be stored in a dry, cool, out of reach of children, t ° not higher than + 25 ° C.
