Effect of Rotigotine Patch Treatment on Cardiovascular Markers in Idiopathic Restless Legs Syndrome
Recruitment status was: Recruiting
Several studies report association between restless legs syndrome (RLS), HTA and cardiovascular diseases .
The mechanisms involved in this relationship remained unknown, but several evidences favor the role of periodic limb movements in sleep (PLMS), patterns frequently associated with RLS. Sympathetic overactivity is associated with PLMS with increased pulse rate and blood pressure coincident with PLMS. PLMS-related repetitive nocturnal blood pressure fluctuations could contribute to the risk of high blood pressure, heart disease, and stroke in patients with RLS, especially in the elderly. Several studies already reported that dopaminergic agonists reduce the severity of RLS and the PLMS index.
Do dopaminergic agonists reduce the risk of cardiovascular diseases and associated autonomic dysfunctions in patients with RLS? Nocturnal BP (blood pressure) decline has major clinical implications, and the loss of normal reduction in BP during sleep is associated with high risk of cardiovascular morbidity and mortality.
The main aim of this study was to evaluate the impact of rotigotine patch treatment on validated cardiovascular risk factors ambulatory BP during night, day and night-to-day ratio, and endothelial function in patients with idiopathic RLS compared to placebo.

Active Comparator: Rotigotine
Patients randomized to rotigotine who will be treated with rotigotine patchs
Subjects randomized to rotigotine will start treatment with a rotigotine dose of 1mg/24h for 1 week. The dose can be increased weekly until either the optimal or the maximal dose of 3mg/24h has been reached. Subjects will maintain the optimal/maximal dose during the 2-week Maintenance Period. Following the Maintenance Period, subjects will be de-escalated from their optimal dose by decreasing the dose by 1mg/24h every other day until complete withdrawal (Taper period).
Other Name: Rotigotine patchs
