Riboxin is a derivative (nucleoside) of purine, a precursor of adenosine triphosphate (ATP). Refers to a group of drugs that stimulate metabolic processes. Has antihypoxic and antiarrhythmic effect. Increases the energy balance of the myocardium, improves coronary circulation, prevents the consequences of intraoperative kidney ischemia. It takes a direct part in the exchange of glucose and promotes the activation of metabolism under conditions of hypoxia and in the absence of ATP.
Activates the metabolism of pyruvic acid necessary to ensure the normal process of tissue respiration, and also promotes the activation of xanthine dehydrogenase. Stimulates the synthesis of nucleotides, enhances the activity of certain enzymes of the Krebs cycle. Penetrating into cells, has a positive effect on metabolic processes in the myocardium - increases the strength of the heart contractions and promotes more complete relaxation of the myocardium in diastole,as a result of which the shock volume increases. The mechanism of antiarrhythmic action is not fully understood.
Reduces platelet aggregation, activates the regeneration of tissues (especially the myocardium and the mucous membrane of the gastrointestinal tract).
