  Purpose

Ropinirole has shown to improve mood in depressed patients as well as to improve the symptoms of Restless Legs Syndrome. Up to 40% of RLS patients suffer from mild depression, therefore it would be important for decisions no therapy to know whether a drug could improve both depressive and RLS symptoms.

  • Secondary RLS due to diagnosis of renal insufficiency, polyneuropathy, pregnancy (see below), iron deficiency anemia
  • Any significant psychiatric disorders (e.g. schizophrenia, bipolar disorder); depression which by judgement of the investigator is caused by RLS, is not an exclusion criterion.

  • medication known to trigger/aggravate/ cause or interfere with RLS symptoms (e.g. most antidepressants, lithium, neuroleptics, opioids, carbidopa, clonidine, antihistamines, anticonvulsants etc.).
  • daytime RLS symptoms which require treatment (daytime: 10 a.m. until 6 p.m.).
  • concomitant movement disorders (e.g. Parkinson's Disease, dyskinesia, dystonia).
  • medical conditions with symptoms which could affect assessments of efficacy (e.g. diabetes, rheumatoid arthritis, fibromyalgia syndrome, cancer etc.).
  • Subjects taking any medication known to induce drowsiness or to affect sleep.
  • Subjects who are pregnant, lactating or of childbearing potential. Women of childbearing potential must use adequate contraception
  • clinically significant or unstable medical conditions (e.g. severe heart disease, severe liver or kidney disease etc.).
  • pain syndromes, caused by other disorders than RLS
  • excessive caffeine intake
  • diastolic blood pressure >110mmHg or <50mmHg or systolic blood pressure >180mmHg or <90mmHg at baseline.
  • Withdrawal, introduction, or change in dose of hormone replacement therapy (HRT) or the oral contraceptive pill (OCP) and/or certain drugs which are known to interact with ropinirole (e.g. ciprofloxacin, cimetidine, tobacco, omeprazole).
