Pharmacology of Vitamin B Complex Injection

Vitamin B Complex Injection

Vitamins belonging to group B possess biological activity in low concentrations and exert a regulating effect on cell function. They participate in a number of enzyme systems and such a manner in the regulation of carbohydrate, protein, and lipid metabolism. After conforming to pyrophosphate, Vitamin B1 participates in carbohydrate and protein metabolism, as well as in the synthesis of nucleic acids as a co-enzyme. It influences the neural impulse conduction in the synapse. Vitamin B2 improves carbohydrate and lipid metabolism and is related to amino acid metabolism. It participates in iron and porphyrin exchange, hemoglobin synthesis, and in tissue respiration.

Vitamin B6 is a part of the following enzymes: Decarboxylase and Transaminase. It participates in histamine, free fatty acid, and amino acid metabolism. The vitamin plays a role in the normal functioning of the central and peripheral nervous system, skin, and gastrointestinal tract. Niacinamide is included in co-dehydrases, participating in the hydrogen transport and oxygenation-restoration processes, necessary for tissue respiration.
