Conditions
-----------------
Healthy

Intervention / Treatment

Eligibility Criteria
-----------------
Inclusion Criteria: Participants should be healthy males and females Age range from 21 to 50 years (Broca-Index): within +-20% of their normal weight In accordance with Good Clinical Practice (GCP) and local legislation all volunteers are supposed to give their written informed consent prior to admission to the study As part of the screening (within 14 days before drug administration), each subject was to receive a complete medical examination (including blood pressure, pulse rate, medical history, documentation of demographics, inclusion/exclusion criteria and concomitant therapy) as well as a 12-lead Electrocardiogram (ECG) and a lung function test (Raw, SGaw). Moreover laboratory parameters (including drug screening, HBs-antigen (HBs-Ag), anti HBc-antibodies, anti HCV- antibodies and Human immunodeficiency virus (HIV) test as well as pregnancy test for female subjects are to be determined Exclusion Criteria: Any finding of the medical examination (including blood pressure, pulse rate and ECG) deviating from normal and of clinical relevance Gastrointestinal, hepatic, renal, respiratory, cardiovascular, metabolic, immunological or hormonal disorders Diseases of the central nervous system (such as epilepsy) or with psychiatric disorders or neurological disorders History of orthostatic hypotension, fainting spells or blackouts 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 a drug with a long half-life (> 24 hours) within at least 1 month or less than ten half-lives of the respective drug before enrolment in the study (except substitution therapy regarding thyroid gland/or ovaries) Use of any drugs which might influence the results of the trial within 1 week prior to administration or during the trial Participation in another study 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 on study days Alcohol abuse (> 60g/day) Drug abuse Blood donation (>= 100 ml) within four weeks prior to administration or during the trial Excessive physical activities within the last week before the study Any laboratory value outside the reference range of clinical relevance For female subjects: Pregnancy Positive pregnancy test No adequate contraception e.g. oral contraceptives, sterilization, intrauterine device (IUD) Inability to maintain this adequate contraception during the whole study period Lactation period
