The purpose of this study is to explore whether patients with restless legs syndrome (RLS) differ from healthy subjects in daytime and night time autonomic function and cardiovascular risk markers and whether 4 week treatment with pramipexole affects autonomic function and cardiovascular risk markers in patients with RLS.
Restless Legs Syndrome
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)
||Autonomic Function and Cardiovascular Risk in Restless Legs Syndrome: AUTOREST, a Case-control Study and a Randomized, Double-blind, Placebo-controlled, Parallel-group, 4-week, Multicenter Study of 0.25mg Pramipexole vs. Placebo in Patients With RLS
Primary Outcome Measures:
Secondary Outcome Measures:
- Change in baroreflex from baseline to 4 weeks [ Time Frame: Baseline, Week 4 ] [ Designated as safety issue: No ]
Baroreflex sensitivity and baroreflex gain derived from tilt table tes
- Change in blood serum markers from baseline to 4 weeks [ Time Frame: Baseline, Week 4 ] [ Designated as safety issue: No ]
Highly-sensitive C reactive protein (hsCRP), lipoprotein-associated phospholipase A2 (lP-PLA2), and oxidised low density lipoprotein (oxLDL)

- Intake of hypnotics (such as benzodiazepines) during the past month.
- Other significant sleep disorder except symptoms potentially related to RLS such as insomnia and daytime sleepiness.
- Any contraindication or known hypersensitivity to dopaminergic drugs.
Additional Exclusion Criteria for Control Subjects
