Outcome Measures

Primary Outcomes (1)

  • Measurement of Time in Minutes From When a Patient Was in a Clinical "Off" State, Took Their Medication and Went Into a Clinical "on" State

    Time to "on" state (benefit with regard to mobility, stiffness and slowness) with parcopa versus carbidopa/levodopa immediate release compound. This measurement is compared between Parcopa and carbidopa/levodopa wit the first morning dose of each intervention. Study duration was 2 days.
