2. Age ≥ 18 and Age ≤ 55 years

3. BMI ≥ 18.5 and BMI ≤ 29.9 kg/m2 (Body Mass Index)

4. History of relevant orthostatic hypotension, fainting spells or blackouts.

5. Relevant acute, chronic or active chronic infections (e.g. hepatitis, HIV).

6. History of allergy/hypersensitivity (including drug allergies) that are deemed relevant to the trial as judged by the investigator

7. Intake of drugs with a long half-life (>24 hours) within at least one month or less than 10 half-lives of the respective drug prior to administration or during the trial

8. Use of drugs which might reasonably influence the results of the trial based on the knowledge at the time of protocol preparation within 10 days prior to administration or during the trial

9. Participation in another trial with an investigational drug within two months prior to administration or during the trial

10. Smoker (more than 10 cigarettes/day or 3 cigars/day or 3 pipes/day)

11. Inability to refrain from smoking on trial days
