[Improvements in motor and non-motor symptoms in parkinson patients under ropinirole therapy].

Ropinirole is a non-ergoline selective D2 dopamine agonist. Its efficacy and safety has been established in several controlled double-blind studies in patients with early and advanced Parkinson's disease. It is assumed that the improvement in the activities of daily living under ropinirole is not only due to the improved motor symptoms but also due to the improvement of non-motor symptoms like symptoms of mood and anxiety. The objective of this post marketing surveillance study was to show that under the conditions of the daily routine in the neurologic practice ropinirole may not only improve motor symptoms, the activity of daily living and complications of the treatment (dystonia, dyskinesia) but also alleviate symptoms of depression and anxiety. A total of 110 neurological practices enrolled 327 patients in early and advanced stages of the disease (139 females, 188-males; mean age: 67 years). They were treated with ropinirole as monotherapy and as adjunctive therapy with l-dopa over a period of 12 - 14 weeks. Selected symptoms of the Unified Parkinson's Disease Rating Scale (UPDRS) part II-IV and symptoms of depression and anxiety were rated by the clinicians. Mood and functional impairment in job, family and social life were rated by the patients using selected items of the Beck Depression Inventory and the Sheehan Disability Scale (SDS). The different subtypes, i. e. the akinetic-rigid, tremor-dominant and the mixed subtype, are described separately. The total UPDRS score at baseline was similar for all three subtypes and there was also a similar improvement in the three groups under ropinirole. Both according to self-rating and to clinician rating the symptoms of depression and anxiety at baseline were more severe in the akinetic-rigid and the mixed subtype compared to the tremor-dominant subtype. The symptoms considerably improved and were reduced by 48 % under therapy with ropinirole. Adverse events were reported by 7.7 % of the patients. The surveillance study has shown that ropinirole may improve not only motor symptoms, activities of daily living and complications of treatment but also symptoms of mood and anxiety.
