ADHD ADD Drug Adderall XR Back on the Market in Canada

Bloomberg reports  Shire Says Canada Allows Sale of Adderall XR Again  after appealing Health Canada’s decision to pull Adderall XR from Canadian shelves.

h Canada’s decision was based on Adderall XR’s link to 20 deaths.

Bloomberg cites that “Adderall XR, used to treat attention deficit hyperactivity disorder or ADHD, will return Aug. 26, the Basingstoke, England- based company said today in an e-mailed statement. The medicine was taken from the market Feb. 9 at the request of Health Canada.

Shares of Shire fell 10 percent the day after the removal in Canada, which only accounted for $10 million of the product’s $606.7 million in 2004 sales. Adderall XR, which has about 25 percent of the hyperactivity market, is also facing patent challenges from companies including Barr Pharmaceuticals Inc. and Impax Laboratories Inc.”

Shire is the UK’s third largest pharmaceutical company.
