- History of relevant orthostatic hypotension, fainting spells, or blackouts
- Chronic or relevant acute infections
- History of relevant allergy or hypersensitivity (including allergy to the trial medication or its excipients)
- Use of drugs within 30 days prior to administration of trial medication if that might reasonably influence the results of the trial (incl. QT/QTc interval prolongation)
- Participation in another trial where an investigational drug has been administered within 60 days prior to planned administration of trial medication, or current participation in another trial involving administration of investigational drug
- Smoker (more than 10 cigarettes or 3 cigars or 3 pipes per day)
- Inability to refrain from smoking at trial site
- Alcohol abuse (consumption of more than 30 g per day: e.g., 750 ml of beer, 1.5 gous [equivalent to 270 mL] of Sake)
- Drug abuse or positive drug screening
- Blood donation of more than 100 mL within 30 days prior to administration of trial medication or intended donation during the trial
