Treatment of Multiple Sclerosis Using Over the Counter Inosine

Summary

The purpose of this study is to determine whether raising low levels of the natural antioxidant uric acid by the administration of a precursor, inosine, has any therapeutic effect on the progression of Relapsing Remitting Multiple Sclerosis (RRMS) and secondary progressive Multiple Sclerosis (MS).
