Критерии исключения

• Any clinically relevant abnormal findings in physical examination, clinical chemistry, hematology, urinalysis, vital signs, lung function or ECG at screening visit, which, in the opinion of the investigator, may either put the participant at risk because of participation in the study or may influence the results of the study, or the participant's ability to participate in the study.
• Past or present disease, which as judged by the investigator, may affect the outcome of this study. These diseases include, but are not limited to, cardiovascular disease, malignancy, he- patic disease (asymptomatic Gilbert syndrome is allowed), renal disease, hematological disease, neurological disease, endo- crine disease (stable and asymptomatic hypothyroidism with or without Hormone Replacement Therapy (HRT) is allowed) or pulmonary disease (including but not confined to chronic bronchitis, emphysema, tuberculosis, bronchiectasis or cystic fibrosis).

• History of allergic reactions to any active or inactive component of the study medication (including medication for bronchoscopy, e.g. salbutamol, lidocaine, midazolam or propofol).
• Repeated measurement of systolic blood pressure outside the range of 90 to 140 mmHg, diastolic blood pressure outside the range of 50 to 90 mmHg, or pulse rate outside the range of 50 to 90 beats per minute (bpm).
