Brief Summary
The purpose of this study is to determine the effect of three single oral doses of nebicapone (50 mg, 100 mg and 200 mg) on the levodopa pharmacokinetics when administered in combination with a single-dose of controlled release levodopa 100 mg/benserazide 25 mg (Madopar® HBS 125).

pre-dose, ½, 1, 1½, 2, 3, 4, 6, 8, 12, 16 and 24 h post-dose
Area under the plasma concentration-time curve (AUC) from time zero to the last sampling time at which concentrations were at or above the limit of quantification (AUC0-t)
Mean AUC0-t pharmacokinetic parameters of levodopa following oral administration of single-doses of Madopar® HBS 125 concomitantly with placebo or nebicapone
