Information provided by (Responsible Party):
GlaxoSmithKline
  Purpose
This study in RLS patients is designed to assess the affect food has on the absorption, distribution, metabolism and excretion of ropinirole (by dosing some patients in the fasted state and other patients following a high-fat breakfast), and to assess the difference in absorption, distribution, metabolism and excretion of ropinirole if patients are given two 3mg ropinirole tablets versus one 6mg tablet.

Condition Intervention Phase
Restless Legs Syndrome Drug: Ropinirole Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: An Open Label, Repeat Dose, Dose Escalation Study Conducted in RLS Patients to Characterize Pharmacokinetics and Food Effect of Ropinirole Controlled Release for RLS
