[Effect of dopamine agonist pramipexole (mirapex) on tremor, affective disorders and quality of life in patients with Parkinson's disease].
The open 6-month study (the MIRAG study) on the effect of D2/D3 dopamine agonist pramipexole (mirapex) on tremor, affective disorders and quality of life in patients with Parkinson's disease (PD) was carried out. Ninety-eight patients, aged from 42 to 75 years (mean age 63.2+/-10.2 years) were included in the study. Scores on the Hoehn and Yahr scale varied from 1 to 4 (mean 2,5+/-0,8). Seventy percent of patients received levodopa in average dose 351.2+/-279.4 mg; 62% of patients had motor fluctuations and 43% had dyskinesias. Pramipexole was titrated to the effective dose (maximum 3 mg/d, mean 2.1 mg/d). In the end of the study, resting tremor was reduced by 54%, postural and kinetic tremor, as assessed with UPDRS and spirography, by 50% and 15%, respectively. The severity of depressive symptoms measured with the Montgomery-Asberg Scale and a modified version of the Geriatric-Depression Scale (GDS-15) was reduced by 56%. Motor fluctuations and dyskinesias were significantly reduced while cognitive functions were not changed. The clinically significant effect reflected in the reduction of motor and non-motor symptoms was observed in 83% of patients, regardless of disease duration, severity of motor deficit, affective and cognitive disorders,. The drug was well tolerated in all patients, including those older than 70 years. Pramipexole improved quality of life in PD patients due to the attenuation of cardinal motor parkinsonian symptoms as well as symptoms, which were relatively resistant to levadopa, e.g. postural and kinetic tremor, and depression. The therapeutic effect remained for at least 6 months.
