More serious side effects have been reported for glatiramer acetate, according to the FDAs prescribing label, these include serious side effects to the cardiovascular, digestive (including the liver), hematopoietic, lymphatic, musculoskeletal, nervous, respiratory, and urogenital systems as well as special senses (in particular the eyes). Metabolic and nutritional disorders have also been reported; however a link between glatiramer acetate and these adverse effects has not been established.It may also cause Jessner lymphocytic infiltrate. Mechanism of action
Glatiramer acetate is a random polymer (average molecular mass 6.4 kD) composed of four amino acids found in myelin basic protein. The mechanism of action for glatiramer acetate is not fully elucidated. It is thought to act by modifying immune processes that are believed to be responsible for the pathogenesis of MS. Administration of glatiramer acetate shifts the population of T cells from proinflammatory Th1 T-cells to regulatory Th2 T-cells that suppress the inflammatory response. Given its resemblance to myelin basic protein, glatiramer acetate may act as a decoy, diverting an autoimmune response against myelin.
