What is dimethyl fumarate, and how does it work (mechanism of action)?
Dimethyl fumarate is an oral disease-modifying
agent used for treating relapsing forms of multiple sclerosis (MS).
Teriflunomide (Aubagio), Interferon beta-1a
(Avonex), interferon beta-1b (Betaseron), glatiramer acetate (Copaxone), interferon beta-1b
(Gilenya), mitoxantrone (Novantrone), interferon beta-1a (Rebif), and
(Tysabri) are other disease modifying agents for multiple sclerosis.
Although the exact mechanism of how dimethyl fumarate works is unknown, it is
thought to have protective effects on the nervous system and anti-inflammatory
properties. Dimethyl fumarate prevents the immune cells from attacking the
central nervous system. Dimethyl fumarate reduces the number of annual relapses
rate. The FDA approved dimethyl fumarate in March 2013.
