People with Parkinson's Disease who had unsatisfactory early-morning motor symptom control were given either rotigotine (2mg-16mg rotigotine every 24 hours) or a placebo. Neupro® (Rotigotine Transdermal System) is a dopamine agonist that is applied to the skin in order to continuously deliver rotigotine over a 24-hour period. For more information go to Neupro. Movement  symptoms had improved in comparison to the use of a placebo, but not greatly as was claimed by the researchers. Sleep had also improved in comparison to a placebo. The most frequently reported adverse events were nausea (rotigotine 21% v 9% placebo), application site reactions (rotigotine 15% v 4% placebo), and dizziness (rotigotine 10% v 6% placebo). 

In April 2008, Neupro was withdrawn from use in the U.S.A. because specific batches of Neupro had deviated from their specification. In June 2009, UCB proposed new refrigerated storage conditions to alleviate crystallization on the patches. UCB has already made progress in reformulation and remains committed to bringing Neupro to U.S. patients. For more information go to the News release.
