Concomitantly with the BIA 6-512/Placebo dose, subjects will be administered levodopa/benserazide 100/25 mg. All subjects attended to each 5 treatment periods and received a different dose of BIA 6-512 or placebo in combination with a single-dose of controlled release levodopa/benserazide 100/25 mg in each of these treatment periods. The washout period between periods was 5 days or more.
