The triple combination of levodopa, DDCI and entacapone (Stalevo) is used to treat motor complication in patients with Parkinson's disease. In this study we summarized the clinical data of our patients treated with Stalevo for the longest period. We can concluded, that after switching to Stalevo due to wearing off, the average levodopa doses were lower then before and the motor complications were milder. After 3 years of Stalevo therapy the levodopa doses were increased but still did not reach the average doses before introducing Stalevo. After switching the patients' general well-being was improved as indicated by the visual analogue scale. In summary, the Stalevo treatment is safe and effective for long run and improves the patients' quality of life.
