[The dopamine agonist, lisuride, in the therapy of Parkinson disease].

The development of fluctuations in disability are a main problem of the levodopa long-term treatment in Parkinson's disease. The early combination of low doses of levodopa with a dopamine agonist as lisuride improves the symptoms of Parkinson's disease as much as a monotherapy but prevents the development of fluctuations in disability and dyskinesias at the same time.
