• Participation in other clinical trials during the previous month in which an investigational drug or a commercially available drug was tested.
• Loss of 500 mL blood or more during the 3 month period before the study, e.g., as a donor.
• Existence of any surgical or medical condition which might interfere with the absorption, distribution, metabolism or excretion of the drug, i.e., impaired renal or hepatic function, diabetes mellitus, cardiovascular abnormalities, chronic symptoms of pronounced constipation or diarrhoea or conditions associated with total or partial obstruction of the urinary tract.
• Symptoms of a significant somatic or mental illness in the 4 week period preceding drug administration.

• Positive results of the drug screening.
• Known hypersensitivity to BIA 9-1067.
• Heavy smokers, i.e., more than 10 cigarettes per day
• Exposure to artificial ionizing radiation in the last 12 months (e.g., x-ray investigation)
