Brief Summary
To investigate the effect of four single oral doses of BIA 6-512 (25 mg, 50 mg, 100 mg and 200 mg) on levodopa pharmacokinetics when administered in combination with a single-dose of controlled release levodopa/benserazide 100/25 mg and to assess the tolerability and safety of four single oral doses of BIA 6-512 (25 mg, 50 mg, 100 mg and 200 mg) when administered in combination with a single-dose of controlled release levodopa/benserazide 100/25 mg.
