The first medication approved by the FDA for MS, in 1993, was interferon beta-1b (Betaseron, Extavia). It is indicated for the treatment of relapsing forms of MS to reduce the frequency of clinical exacerbations. It has shown efficacy in patients who have experienced a first clinical episode of MS and have MRI features consistent with MS. [7]
