7. History of drug abuse within 1 year before study Day 1.

8. History of alcoholism within 1 year before Day 1. Consumption of more than 50 g of ethanol per day (12.5 cL glass of 10° [10%] wine = 12 g; 4 cL of aperitif, 42° [42%] whiskey = 17 g; 25 cL glass of 3° [3%] beer = 7.5 g; 25 cL glass of 6° [6%] beer = 15 g).

9. History of any clinically important drug allergy.

10. Had previously received BIA 9-1067.

Prohibited treatments and dietary restrictions

11. Consumption of any caffeine-containing products (e.g., coffee, tea, chocolate, or soda) in excess of 6 cups per day (or equivalent), of grapefruit, grapefruit-containing products, or alcoholic beverages within 24 hours before study Day 1.

12. Use of any over-the-counter drugs including herbal supplements (except for the occasional use of acetaminophen [paracetamol], aspirin and vitamins ≤100% recommended daily allowance) within 7 days before IMP administration.

13. Donation of blood (i.e. 450 ml) within 60 days before study Day 1.

Young subjects only:

Prohibited treatments and dietary restrictions

14. Prohibited Treatments: use of any investigational drug within 90 days (young and elderly subjects) or prescription drug within 30 days before investigational medical product (IMP) administration.

Elderly subjects only:

Prohibited treatments and dietary restrictions

15. For elderly subjects, previously prescribed medications that do not interfere with absorption, distribution, metabolism, and excretion or safety/tolerability evaluation of BIA 9-1067 and adrenal or renal function were allowed if the dose regimen had been stable for at least 4 weeks and was expected to remain stable throughout the study. Such concomitant medications was reviewed and mutually agreed upon by the sponsor and the investigator.
