This study was designed to compare the effectiveness and tolerability of a new prolonged release formulation of ropinirole with the currently marketed immediate release formulation which is prescribed in many countries. The new prolonged release formulation allows the drug to be taken once a day rather than three times a day. This study will also evaluate the side effects of the new prolonged release formulation of ropinirole

Primary Outcome Measures:
  • Diary information to compare the amount of time "off"(time "off" includes a lack of mobility with or without additional features such as tremor or rigidity)the patient experiences at the start and end of the study. [ Time Frame: 24 Weeks ]

Secondary Outcome Measures:
