Drug patches have had a tough time lately, with recalls coming on everything from too-tight adhesive to slits in active-ingredient reservoirs. Today, the recalled patch in the news is Shire's Daytrana, an attention deficit hyperactivity disorder med. Two lots were withdrawn on concerns about the patch's liner, which could be difficult for patients to remove before applying the patch. Shire recalled a limited number of patches for the same reason just a year ago.
Shire sells the patches on license from Noven Pharmaceuticals, which sent out a statement saying that it has identified the "definitive root cause" of the defect and is now "aggressively testing potential solutions."
