Pharmacological action
Cyanocobalamin exerts an erythrogenic, hematopoietic, antianemic, metabolic effect. High biological activity ensures the participation of cyanocobalamin in lipid, carbohydrate and protein metabolism. It stimulates the ability of tissues to regenerate, normalizes blood formation processes, functions of the nervous system and liver, activates the blood coagulation system, increases the activity of prothrombin and thromboplasts (in high doses), reduces blood cholesterol. In the body, it is transformed into a cofactor – cobamide (the active form of vitamin B12), which takes part in the transfer of methyl groups and other monocarbon fragments and is necessary for the formation of DNA and deoxyribose, methionine, creatine, choline. It accelerates the maturation of red blood cells, promotes the accumulation of compounds with sulfhydryl groups in them, thereby increasing their tolerance to hemolysis.
Cyanocobalamin is absorbed in the small (partly in the large) intestine, combining with an internal factor, it becomes protected from intestinal microflora. In the mucosa of the small intestine, the complex transfers vitamin B12 to the receptor, which carries it into the cell. In the blood, cyanocobalamin combines with transcobalamin I and II, with which it is transported to tissues. Cyanocobalamin is deposited mainly in the liver, excreted from the liver with bile into the intestine, from where it is again absorbed. Eliminated from the body by the kidneys. Penetrates through the placental barrier.
Indications
Cyanocobalamin is used in the treatment of chronic anemia with vitamin B12 deficiency (alimentary macrocytic anemia, Addison-Birmer disease), as part of the complex treatment of anemia (posthemorrhagic, iron deficiency, aplastic drugs), as well as toxic drugs, as well as anemic drugs, and also . It is used in the treatment of chronic hepatitis, cirrhosis of the liver, liver failure of alcoholism, prolonged fever polyneuritis, neuralgia (including trigeminal neuralgia), radiculitis. Vitamin B12 is prescribed in the treatment of funicular myelosis, malnutrition, peripheral nerve injuries, cerebral palsy, amyotrophic lateral sclerosis, Down’s disease.
Cyanocobalamin is indicated for skin diseases: psoriasis, herpetiform dermatitis, photodermatitis, atopic dermatitis.

For the purpose of prevention when using PASK, biguanides and ascorbic acid in large doses, with pathology of the intestines and stomach with impaired absorption of vitamin B12 (resection of the small intestine, part of the stomach, Crohn’s disease, malabsorption syndrome, celiac disease).
