Dexedrine® is indicated for the treatment of attention deficit hyperactivity disorder (ADHD) and in the adjunctive treatment of narcolepsy. According to IMS Canada, the ADHD market in Canada was valued at about $120 million in 2007 and Dexedrine® recorded sales of over $14 million in the same year, representing a market share of 12% and making it the third largest product in this category.

"This agreement will allow us to add to our portfolio of specialty pharmaceutical products and to build significant critical mass for our organization. Not only will we be adding close to $14 million to our top line next year, but just as importantly, we are establishing a strategic relationship with GSK for potential future transactions like this one," said Jonathan Ross Goodman, President and CEO of Paladin Labs Inc. "We are very pleased to establish this preferred partner relationship with Paladin owing to their clear history of success in commercializing products like Dexedrine® and their record of building win-win relationships with partners," said Paul Lucas, President and CEO of GSK. "Dexedrine® has a long history of efficacy and safety in improving the lives of Canadians suffering from ADHD and narcolepsy. In the very capable hands of Paladin, we are confident that it will continue to meet the needs of Canadian patients and their healthcare providers."
