Exclusion Criteria: * Participation in another clinical study with an investigational drug in the 30 days or five half-lives of that investigational drug (whichever is longer) preceding the administration of the study treatment; longer and more appropriate time could be considered by the Investigator based on the terminal half-life (t1/2) and/or long-term toxicity of the previous investigational drug; * Clinically relevant and uncontrolled respiratory, cardiac, hepatic, gastrointestinal, renal, endocrine, metabolic, neurologic or psychiatric disorders that may interfere with successful completion of this protocol according to the Investigator's judgment; * Subjects with history of breathing problems (i.e. history of asthma including childhood asthma); * Positive urine test for cotinine. * Intake of non-permitted concomitant medications in the predefined period prior to screening, or prior to randomisation or the subject is expected to take non-permitted concomitant medications during the study; * Presence of any current infection, or previous infection that resolved less than 7 days prior to screening or prior to randomisation; * Known intolerance and/or hypersensitivity to any of the excipients contained in the formulation used in the study; * Subjects with medical diagnosis of narrow-angle glaucoma, prostatic hypertrophy or bladder neck obstruction that in the opinion of the Investigator would prevent use of anticholinergics; * For females only: pregnant or lactating women. * Subjects receiving treatment with any drug known to have a well defined potential for hepatotoxicity. * Subjects using e-cigarettes within 6 months before screening. Other Inclusion/exclusion criteria as defined by the protocol.
