An Open Label, Repeat Dose, Dose Escalation Study Conducted in Parkinson's Disease Patients to Characterize the Pharmacokinetics and Effect of Food on Ropinirole Prolonged Release (PR/CR) 12mg Tablets.

This study in PD 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 three 4mg ropinirole tablets versus one 12mg tablet.
