Brief Summary
The study aimed to investigate the effect of BIRT 2584 XX and its metabolite BI 610100 on the Pharmacokinetics (PK) of five probe substrates for cytochrome P450 isozymes. The substrates used to monitor enzyme activity were oral warfarin (for CYP2C9), oral omeprazole (for CYP2C19), oral dextromethorphan (for CYP2D6), oral caffeine (for CYP1A2) and intravenous midazolam (for hepatic CYP3A)

- non-smoker (a subject is considered to be a non-smoker if he has never smoked or has stopped smoking ≥ 6 months before the screening visit)
- agree not to take any prescription medications or non-prescription drugs (including herbal preparations and vitamins) without approval by the investigator and not to receive vaccinations during the course of the study
- agree not to eat oranges, grapefruits, broccoli, Brussels sprouts, or char grilled meats and not to drink grapefruit juice during the course of the study
- agree not to drink alcoholic beverages during the course of the study
- agree not to drink or eat caffeine and theobromine containing beverages and foods during the course of the study
You may not qualify if:
- any finding of the medical examination (including Blood Pressure, Pulse Rate, and ECG) deviating from normal and of clinical relevance
- gastrointestinal, hepatic, renal, respiratory (e.g. asthma), cardiovascular, metabolic, immunologic, haematological, oncological, or hormonal disorders
- any surgical or medical condition that could interfere with the administration of the study drug or interpretation of the study results
- diseases of the Central nervous system (CNS) (such as epilepsy) or psychiatric disorders or neurological disorders
- relevant history of orthostatic hypotension, fainting spells, or blackouts
- chronic or relevant acute infections
- history of allergy/hypersensitivity (including drug allergy) considered relevant to the trial as judged by the investigator
- immunisation during the 2 weeks prior to the screening visit
- known intolerance to benzodiazepines
- known intolerance to the active and/or inactive ingredients in caffeine, warfarin, vitamin K1, omeprazole, or dextromethorphan
- known acute angle-closure glaucoma
- elevated prothrombin time as determined by Prothrombin time (INR) \> 1.3
- intake of drugs with a long half-life (greater than 24 hrs) (less than one month prior to administration or during the trial)
- use of any drugs which might influence the results of the trial (less than 10 days prior to study drug administration or expected during the trial)
- use of chewing tobacco or nicotine replacement devices within 6 months before the screening visit
- +4 more criteria
