Azathioprine in multiple sclerosis

Abstract

Azathioprine is an immunosuppressive and steroid-sparing purine analogue, used in the treatment of several autoimmune diseases. In multiple sclerosis, available evidence suggests that oral azathioprine reduces relapse rates, provides a slight benefit on disability, and reduces new inflammatory lesions. Here, we focus on molecular mechanisms of Azathioprine and on its usefulness in multiple sclerosis.
