The British group said on Thursday up it would receive up to $230
million in sales and other related milestones over the lifetime of
the contract, with Gruenenthal also paying royalties on sales.
In April, Ironwood Pharmaceuticals bought U.S. marketing rights to
the newly approved drug for up to $265 million.
AstraZeneca has a strategy of selling certain rights to non-core
medicines as it invests in new drugs. But the disposal of Zurampic

acquisitions, since AstraZeneca only bought the drug's original
developer Ardea Biosciences in 2012 for $1.26 billion.
