Riboxin is a purine derivative. It can be considered a nucleoside that is a substance naturally found in the cells of the body and is the precursor of adenosine triphosphate – ATP.

The main component of the drug is inosine. It is part of a group of drugs with a metabolic effect. Once in the heart muscle, this substance is known to stabilize and activate the energy balance. It may normalize metabolism in the myocardium. Riboxin takes part in glucose metabolism, improves digestion, and helps in liver and kidney diseases therapy including renal ischemia.

Inosine demonstrates the possibility to enhance heart contractions and relaxe myocardial fibers during diastole, after which the stroke volume of the blood becomes larger. It is stated to improve blood circulation in coronary vessels and improve the condition of areas with reduced blood supply. It stimulates the restoration of anemic tissues, reduces platelet plug, and may restore myocardial tissue and gastrointestinal mucosa.

Riboxin can also normalize tissue respiration, demonstrating an antihypoxic effect and accelerating the utilization of oxygen circulating in the body. It may also reduce the deficiency of oxygen of internal organs, associated with the lack of the latter. It activates metabolism in hypoxia, and increases resistance to oxygen deficiency. Riboxin shows an antiarrhythmic effect, normalizing heart contractions.

The properties of Riboxin determine its most important contribution which is considered to be the treatment of cardiovascular diseases. Riboxin is prescribed for adults with: heart rhythm disturbances; severe forms of ischemia; myocardial infarction; arrhythmias caused by excess doses of glycosides; myocarditis; damage to the coronary arteries that feed the heart; “pulmonary” heart (increase or expansion of its sections); individual forms of glaucoma; congenital or acquired heart abnormalities; myocardial dystrophy caused by physical overload or endocrine pathology; disorders of the liver, etc.

*The drug is also of wide use among athletes, since its use is asserted to enhance the restoration of carbohydrate, protein and fat metabolism, which increases the body’s defenses and the effectiveness of training.
