AUBAGIO

TERIFLUNOMIDE Dihydroorotate Dehydrogenase Inhibitors
Neurology Approved 2012-09-12

Aubagio (teriflunomide) is a pyrimidine synthesis inhibitor indicated for the treatment of relapsing forms of multiple sclerosis (MS) in adult patients. The medication is used to manage several manifestations of the condition, including clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease. As an immunomodulatory agent with anti-inflammatory properties, it provides a therapeutic approach for adults diagnosed with these specific relapsing forms of MS.

How AUBAGIO Works

Teriflunomide functions by inhibiting dihydroorotate dehydrogenase, a mitochondrial enzyme involved in de novo pyrimidine synthesis. Although the exact mechanism of action in multiple sclerosis is unknown, the drug's activity may result in a reduction of activated lymphocytes in the central nervous system. Through this inhibition of pyrimidine synthesis, the agent exerts its immunomodulatory and anti-inflammatory effects.
