NCT03097211

Brief Summary

The purpose of this study was to determine whether the administration of BIA 6-512 (25 mg, 50 mg, 75 mg and 100 mg) at steady-state affects the pharmacokinetics of levodopa when administered in combination with a single-dose of immediate release levodopa/benserazide 200/50 mg or with a single-dose of immediate release levodopa/benserazide 200/50 mg plus a single-dose of nebicapone 150 mg.
