The 10 best-selling drugs of 2013, March 25, 2014
Enbrel, The companies: Amgen, Pfizer, Takeda, Worldwide sales: $8.776 billion

Excerpt:
Enbrel was the first of its kind, a TNF (tumor necrosis factor) inhibitor to treat autoimmune diseases, and its distinction allowed it to become one of the best-selling drugs in the world. It was first approved by the FDA more than 15 years ago in 1998 for treating moderate to severe rheumatoid arthritis, but it has racked up four more approvals in the U.S. since then and the revenues to go with it. Amgen bought its developer, Immunex, in 2002 for about $16 billion, a deal that seemed incredible to some at the time, but that in retrospect was a bargain.
