Exclusion criteria
* Evidence of clinically significant cardiovascular, renal, hepatic, haematological, gastrointestinal, pulmonary, metabolic, endocrine, neurological or psychiatric disease or cancer (except local non-melanoma skin cancer) within the previous 2 years. * Any condition requiring regular concomitant treatment (including vitamins and herbal products) or likely to need any concomitant treatment during the study. As an exception, paracetamol for occasional pain is allowed. * Any clinically significant abnormal laboratory value or ECG (such as prolonged QTcF \> 450 ms or QRS \> 120 ms) that in the opinion of the investigator could interfere with the interpretation of study results or cause a health risk for the subject if he takes part in the study. * Known hypersensitivity to the active substances or the excipients of the drugs. * History of vasovagal collapses or vagal reactions with unexplained reason within the previous 2 years or a tendency for vasovagal reactions during blood sampling. * HR \< 40 beats per minute (bpm) or \> 90 bpm in the supine position after 5 min rest at the screening visit. * At the screening visit:systolic BP \< 90 mmHg or \> 150 mmHg in the supine position after 5 min rest and diastolic BP \< 50 mmHg or \> 90 mmHg in the supine position after 5 min rest. * History of anaphylactic/anaphylactoid reactions. * Strong tendency to motion sickness. * Recent or current (suspected) drug abuse. * Recent or current alcohol abuse; regular drinking of more than 21 units per week (1 unit = 4 cl spirits or equivalent). * Current use of nicotine containing products more than 5 cigarettes (or equivalent)/day and/or inability to refrain from the use of nicotine containing products during the study (from the screening visit to the end-of-study visit). * Use of caffeine containing beverages more than 600 mg of caffeine/day and/or inability to refrain from using caffeine containing beverages 10 h before and during the study periods. * Blood donation or loss of a significant amount of blood within 90 days before the first study treatment administration. * Participation in an investigational drug study or administration of an investigational drug within 90 days before the first study treatment administration. * Unsuitable veins for repeated venipuncture or cannulation. * Predictable poor compliance or inability to communicate well with the study centre personnel. * Inability to participate in all treatment periods.
