Merck Serono commercial director Charles Dring said the gastroenterology business is a strong and growing operation in the UK and Ireland, but the company has made a strategic decision to focus on its core pharmaceutical business.

"We have been working very closely with CORPAK to make the transition as seamless as possible for our customers," Dring added.

Corpak president Tom Kuhn said, "The acquisition of the Merck Serono gastroenterology business strengthens our presence in Europe and our direct operation will support high levels of customer service and continued growth."

Corpak CEO Jeff Blair said, "We are confident that the UK and Ireland team will continue the history of excellence and dedication that has benefitted our customers in the past."
