7. History of alcohol dependence or drug abuse in the last 5 years or daily consumption of alcohol > 40 g or high consumption of stimulating beverages (> 5 coffees, teas or coca cola drinks/ day).
8. Abnormal physical findings of clinical significance at the screening examination or baseline which would interfere with the objectives of the study.
9. Need of any prescription medication within 14 days prior to the administration of the drug and non prescription medication or herbal medicines within 7 days prior to the administration of the drug.
10. Participation in other clinical trials during the previous 90 days in which an investigational drug or a commercially available drug was tested.

12. Existence of any surgical or medical condition which might interfere with the absorption, distribution, metabolism or excretion of the drug, i.e. impaired renal or hepatic function, diabetes mellitus, cardiovascular abnormalities, chronic symptoms of pronounced constipation or diarrhea or conditions associated with total or partial obstruction of the urinary tract.
13. 12 lead ECG obtained at screening with PR ≥ 220 msec, QRS ≥120 msec and QTc ≥ 440 msec, bradycardia (<50 bpm) or clinically significant minor ST wave changes or any other abnormal changes on the screening ECG that would interfere with measurement of the QT interval.
14. Symptoms of a significant somatic or mental illness in the four week period preceding drug administration.
15. History of hepatitis HBV and / or HCV and / or positive serology results which indicate the presence of hepatitis B surface antigen and / or detectable HCV ribonucleic acid (RNA).
