Pharmacological properties

Hepadif is a combined drug whose pharmacological effects are due to the complex action of its components. It stimulates the metabolism of fats - components of the β-oxidative conversion of free fatty acids in hepatocyte mitochondria, biosynthetic processes, prevents hepatocyte necrosis, normalizes hepatocyte proliferation processes, the system of liver enzymes and helps restore normal liver function. the presence of adenosine, which is a component of coenzymes, nucleic acids, ensures the regulation of hematopoiesis. B vitamins (cyanocobalamin, riboflavin, pyridoxine) regulate redox processes in the body, participate in protein, fat and carbohydrate metabolism, in the exchange of amino acids - tryptophan, methionine, cysteine, glutamic acid and other amino acids. pyridoxine contributes to the normalization of lipid metabolism, the functioning of the central and peripheral nervous system. cyanocobalamin is involved in the process of transmethylation, hydrogen transfer, synthesis of methionine, nucleic acids, choline, creatine, helps to normalize impaired functions of the liver, nervous system, blood formation, increases the ability of tissues to regenerate. cyanocobalamin and pyridoxine reduce fatty liver, reduce hyperhomocysteinemia. riboflavin is part of the enzymes involved in the transport of oxygen and the formation of atph in mitochondria.

Carnitine regulates the metabolism of fats, promotes the breakdown of long chain fatty acids and the replacement of a fatty acid metabolic shunt with a carbohydrate, reduces the indicators of fatty degeneration of the liver, and improves the absorption of food.

The antitoxic fraction of the liver extract is an indispensable and interchangeable amino acids that participate in the synthesis of proteins, are donors of sulfhydryl and methyl groups, have antitoxic and antioxidant effects.

Hepadif stimulates the digestion and secretion of bile, facilitates the absorption of carbohydrates in the small intestine, is necessary for the functioning of the normal intestinal microflora. Helps increase the glycogen-fixing, synthetic, antitoxic function of the liver, increases the sensitivity of cells to insulin, and promotes the increase of insulin.

Pharmacokinetics Capsules After oral administration, a complex of active substances is released in the duodenum. The absorption of water-soluble B vitamins (cyanocobalamin, riboflavin, pyridoxine), carnitine orotate, the antitoxic fraction of the liver extract, adenine hydrochloride occurs along the entire length of the small intestine. Cyanocobalamin is deposited mainly in the liver, as well as in the kidneys, intestinal wall. Re-absorbed in the lumen of the intestine, where it is excreted along with bile. Riboflavin is distributed unevenly in the body: the largest amount is detected in the myocardium, liver, and kidneys. Pyridoxine is metabolized in the liver with the formation of pharmacologically active metabolites (pyridoxalphosphate, pyridoxaminophosphate); distributed in muscles, liver, central nervous system. Excretion is carried out mainly by the kidneys.

Rr. After iv drip, the distribution of the active components of the drug - water-soluble B vitamins (cyanocobalamin, pyridoxine), carnitine, the antitoxic fraction of the liver extract, adenosine - occurs mainly in the liver and kidneys. Pyridoxine is metabolized in the liver with the formation of pharmacologically active metabolites (pyridoxalphosphate, pyridoxaminophosphate), distributed in the muscles, liver, and central nervous system. It is allocated mainly by kidneys.


As part of complex therapy: acute and chronic hepatitis, cirrhosis; fatty liver (liver steatosis); alcoholic liver damage; intoxication due to prolonged use of antitumor and anti-tuberculosis drugs.

From the respiratory system: shortness of breath.

From the side of metabolism: acne, bullous rash, nausea, sweating, impaired purine metabolism, decreased folic acid level.

On the part of the immune system: hypersensitivity reactions, including skin manifestations (hyperemia, urticaria, rash, itching, dermatitis, photosensitivity, etc.), edema (Quinckes edema), respiratory failure (suffocation, anaphylactic shock, angioedema, anaphylactoid reactions).

From the gastrointestinal tract: dyspepsia, pain and discomfort in the abdomen, pain in the epigastric region, heartburn, increased gastric secretion, nausea, vomiting, diarrhea, constipation, weakening of the stool.

From the reproductive system and mammary glands: suppression of lactation in the lactogenic period.

Common disorders: malaise, weakness, fever.

Local reactions: changes at the injection site, including flushing, burning, itching, pain, swelling, induration and necrosis at the injection site.

The presence of methyl parahydroxybenzoate (E219), propyl parahydroxybenzoate (E217) in the preparation can cause allergic reactions (possibly delayed), and in some cases bronchospasm.

special instructions

Use with caution in patients with a history of gastric and duodenal ulcers (due to a possible increase in the acidity of gastric juice), in severe diseases of the heart and kidneys, and neoplasms.

The use of the drug can lead to a false positive test for urobilinogen using Ehrlich reagent.

Parenteral Administration of Vitamin B12 may temporarily affect the diagnosis of funicular myelosis or pernicious anemia. It can not be used with drugs that increase blood coagulation.

For people with a tendency to thrombosis and patients with angina pectoris during treatment, care must be taken to monitor blood coagulation.

During treatment should not drink alcoholic beverages.

Influence on the ability to drive vehicles and work with mechanisms. There was no negative impact on the ability to drive vehicles and work with mechanisms.


Vitamin B6 weakens the effect of levodopa, prevents or reduces the severity of toxic manifestations that are noted with the use of isoniazid and other anti-TB drugs.

PASK, cimetidine, calcium preparations, ethanol reduce the absorption of vitamin B12.

Riboflavin is incompatible with streptomycin and reduces the effectiveness of antibacterial drugs (oxytetracycline, doxycycline, erythromycin, tetracycline and lincomycin). Tricyclic antidepressants, imipramine and amitriptyline, inhibit the metabolism of riboflavin, especially in the heart tissue.

Interactions due to the presence of cyanocobalamin

Aminoglycosides, salicylates, antiepileptic drugs, colchicine, potassium preparations reduce the absorption of the drug, affect its kinetics.

With simultaneous use with kanamycin, neomycin, polymyxins, tetracyclines, the absorption of cyanocobalamin is reduced.
