How long should I wait to see the results of Comtan?

Comtan was seen to prolong the clinical effect of each levodopa dose as soon as after its first administration. In clinical studies, Comtan led to increases in daily on time as early as after two weeks, and those benefits became significantly greater than with a placebo after about eight weeks. However, because Parkinson’s disease varies from person to person, and not everyone responds the same way to Comtan, the time it takes to see its benefits also will vary.
