Brief summary

1. In order to compare the benefit, side effects, and patient preference of Ropinirole prolonged release when used in once-daily or twice-daily dosing 2. In order to estimate the conversion rate of dopamine agonists into Ropinirole prolonged release

Detailed description

1. Study subjects : Parkinson disease who are on Ropinirole immediate release or Pramipexole immediate release and are considering to change into Ropinirole prolonged release 2. Cross over study design: * Group 1: once daily dose for 2 month then into twice daily in divided dose for 2 months * Group 2: twice daily in divided dose for 2 months then into once daily dose for 2 months 3. Dose adjustment may be done in the first 4 weeks. 4. Compare the benefit,side effects, and patient preference between the once daily vs twice daily dosing.
