Glatiramer acetate (also known as Copolymer 1, Cop-1, or Copaxone – as marketed by Teva Pharmaceuticals) is an immunomodulator drug currently used to treat multiple sclerosis. It is a random polymer of four amino acids found in myelin basic protein, namely glutamic acid, lysine, alanine, andtyrosine, and may work as a decoy for the immune system. Glatiramer acetate is approved by the Food and Drug Administration (FDA) for reducing the frequency of relapses, but not for reducing the progression of disability.Observational studies, but not randomized controlled trials, suggest that it may reduce progression of disability.

Although the clinical definition of multiple sclerosis requires two or more episodes of symptoms and signs, glatiramer acetate is approved for treatment after single episodes. It is also used to treat relapsing-remitting multiple sclerosis. It is administered by subcutaneous injection.
The U.S. Food and Drug Administration today approved the firstgeneric version of Copaxone (glatiramer acetate injection), used to treat patients with relapsing forms of multiple sclerosis (MS). Sandoz has received FDA approval to market generic glatiramer acetate in a 20 mg/1 ml daily injection.
The mechanism(s) by which glatiramer acetate exerts its effects in patients with Multiple Sclerosis (MS) is (are) not fully elucidated. However, it is thought to act by modifying immune processes that are currently believed to be responsible for the pathogenesis of MS. This hypothesis is supported by findings of studies that have been carried out to explore the pathogenesis of experimental autoimmune encephalomyelitis (EAE), a condition induced in several animal species through immunization against central nervous system derived material containing myelin and often used as an experimental animal model of MS. Studies in animals and in vitro systems suggest that upon its administration, glatiramer acetate-specific suppressor T-cells are induced and activated in the periphery.
