How GLATIRAMER ACETATE Works

Although the exact mechanism is not fully understood, glatiramer acetate is thought to work by modifying immune processes responsible for the pathogenesis of multiple sclerosis. Evidence suggests that administration of the drug induces and activates specific suppressor T-cells in the peripheral immune system. These activated cells are believed to influence the immune functions that drive the progression of the disease.
