Riboxin is a derivative (nucleoside) of purine. It can be considered as a precursor of ATP.

By type of action refers to anabolic substances. As a nucleoside, inosine can enter cells and increase the energy balance of the myocardium.
Riboxin is used for the treatment of ischemic heart disease, myocardial infarction, myocardial dystrophy, rhythm disturbances associated with the use of cardiac glycosides.
