- •Chronic or relevant acute infections
- •History of allergy/hypersensitivity (including drug allergy) which is deemed relevant to the trial as judged by the investigator
- •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
- •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
- •Participation in another trial with an investigational drug within two months prior to administration or during the trial
- •Alcohol abuse (more than 60 g/day)
- •Within 5 days of study medication no intake of grapefruit, grapefruit juice, or products containing grapefruit juice, Seville oranges, garlic supplements, or St. John's Wort
