Description
Riboxin Pharmacodynamics
Metabolic agent, adenosine triphosphate precursor; has antihypoxic, metabolic and antiarrhythmic effects. Increases myocardial energy balance, improves coronary circulation, prevents consequences of intraoperative renal ischemia. It activates pyruvic acid metabolism to ensure normal tissue respiration, and also promotes activation of xanthine dehydrogenase. It stimulates nucleotide synthesis and enhances the activity of some Krebs cycle enzymes. By penetrating the cells, it increases the energy level, has a positive effect on myocardial metabolism, increases the force of heart contractions and contributes to a more complete relaxation of the myocardium in diastole, resulting in an increase in the stroke volume of the blood. Reduces platelet aggregation.
