[Prevention and treatment of fluctuations in patients with Parkinson's disease].

Fluctuations (wearing-off, on off phenomenon, dyskinesias) are a big challenge in the long term treatment of parkinsonian patients. We describe the current strategies for prevention and treatment of fluctuations. Special emphasis is put on two new methods which will soon be available. The new dopamine agonist Rotigotine (Neupro) can be transdermally applied. This is a rather simple way to achieve a continuous dopaminergic stimulation. The same goal is achieved by direct application of levodopa-/carbidopa-gelsuspension (Duodopa) in the duodenum by the help of an electronic pump.
