What is teriflunomide, and how does it work (mechanism of action)?
Teriflunomide is an oral immunomodulatory agent used for the treatment of patients with relapsing forms of multiple sclerosis (MS).

However, it is thought to reduce the over activation of the immune system by decreasing the number of white blood cells (T and B lymphocytes) in the central nervous system.
