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.
