teriflunomide (Aubagio): Facts About Drug Side Effects

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). It inhibits dihydroorotate dehydrogenase, an enzyme used to make
pyrimidine which is used to build DNA. The exact mechanism of action of
teriflunomide in the treatment of MS is unknown. 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.
Teriflunomide decreases the number of MS relapses. The FDA approved
teriflunomide in September 2013.
