- Brief Summary
Primary objective:
To determine the basic pharmacokinetics of BI 1744 BS, its metabolite BI 1744 BS - glucuronide and \[14C\]-radioactivity including excretion mass balance, excretion pathways and metabolism following intravenous and oral administration of \[14C\]BI 1744 CL

Inclusion Criteria
- Healthy males according to the following criteria: Based upon a complete medical history, including the physical examination, vital signs (BP, PR), 12-lead ECG, clinical laboratory tests
- Age ≥18 and ≤45 years
- Body mass index (BMI) ≥18.0 and BMI ≤30.0 kg/m2
- Signed and dated written informed consent prior to admission to the study in accordance with Good Clinical Practice (GCP) and the local legislation
Exclusion Criteria
- Any finding of the medical examination (including BP, PR and ECG) deviating from normal and of clinical relevance
- Any evidence of a clinically relevant concomitant disease
- Gastrointestinal, hepatic, renal, respiratory, cardiovascular, metabolic, immunological or hormonal disorders
- Diseases of the central nervous system (such as epilepsy) or psychiatric disorders or neurological disorders
- History of relevant orthostatic hypotension, fainting spells or blackouts
- Chronic, or relevant acute infections
- History of relevant allergy/hypersensitivity (including allergy to study drug or its excipients)
- 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 until after the last sample from Visit 2 is collected
- Participation in another trial with an investigational drug within two months prior to administration or during the trial
- Smoker (> 10 cigarettes or > 3 cigars or > 3 pipes/day)
- Inability to refrain from smoking during the stay in the trial centre
- Alcohol abuse (more than on average 2 units of alcoholic beverages per day or more than 14 units per week (1 unit equals 1 pint [285 mL] of beer or lager, 1 glass [125 mL] of wine, 25 mL shot of 40% spirit))
- Drug abuse
- Blood donation (more than 100 mL within 60 days prior to study drug administration or during the trial)
- Excessive physical activities (within one week prior to administration or during the trial until follow-up examination)
- Any laboratory value outside the reference range that is of clinical relevance
- Inability to comply with dietary regimen of study centre
- A marked baseline prolongation of QT/QTc interval (e.g., repeated demonstration of a QTc interval >450 ms)
Exclusion criteria specific for this study:
- Veins unsuitable for infusion and blood sampling
- PR interval >220 ms or QRS interval >120 ms
- Exposure to radiation for diagnostic reasons (except dental X-rays and plain X-rays of thorax and bony skeleton (excluding spinal column)), during work or during participation in a medical trial in the previous year
- Irregular defecation pattern (less than once per 2 days)
The following exclusion criteria are specific for this study due to the known class side effect profile of β2-mimetics:
- Asthma or history of pulmonary hyperreactivity
- Hyperthyrosis
- Allergic rhinitis in need of treatment
- Clinically relevant cardiac arrhythmia
- Paroxysmal tachycardia (>100 beats per minute)
