Brief summary

Study to investigate whether psychomotor performance which is necessary for safety driving a car or operating machinery and safely participating in daily life is changed by Aggrenox®. Also to investigate whether Aggrenox® impairs performance in combination with alcohol more than alcohol alone. Derived from this: Statement on whether a warning for drivers is necessary
