Wow no wonder MS is seen as a Cash Cow.
Teva soaring out in front on a single product and it is no surprise that the Generics pack are waiting in the rear ready for the copaxone patents to expire starting May 2014. However Biogen are backing the most winners with a staggering $5.8 billion worth of business
Interesting that sales of Extavia are so much lower than Betaseron, for what is essentially the same product in different packaging. This shows what brand loyalty and a bit of marketing can do.
