Rotigotine transdermal system for the treatment of Parkinson's disease.

Background: Levodopa has been the cornerstone of the treatment of Parkinson's disease (PD) for >30 years, but long-term levodopa therapy is associated with development of such motor complications as motor fluctuations, dyskinesias, and drug-induced involuntary movements. Rotigotine is a dopamine agonist with high affinity for the D2 receptor. Rotigotine transdermal system, the first such system approved by the US Food and Drug Administration for the management of PD, has been formulated to deliver a consistent concentration of drug to the bloodstream with the goal of minimizing the complications associated with pulsatile dosing.
