Description
Inclusion Criteria:
- Male or female Caucasian.
- Age 40-65 years.
- Body mass index (BMI) between 18 and 30 kilograms/square meter (extremes included).
- Extensive Cytochrome P450 2D6 (CYP2D6) metabolizer.
- Healthy as determined by medical history, physical examination, vital signs, 12-lead electrocardiogram (ECG), and clinical laboratory parameters (haematology, Blood sedimentation rate (BSR), clotting, bio-chemistry, urinalysis and virus serology). Minor deviations of laboratory values and ECG parameters from the normal range may be accepted, if judged by the investigator as clinically not relevant and if not considered to interfere with the study objectives.
- Adequate contraception. For females of childbearing potential (i.e. all females except surgically sterilized or at least 2 years postmenopausal) this is defined as follows: any form of hormonal contraception or intra-uterine device must be used, at least for 4 weeks prior to the first dosing AND she must give a consent to use an additional barrier contraception (condom or diaphragm) from 2 weeks prior to first dosing up to 4 weeks after the last dosing.
- Written consent to participate in the study.
- Negative Human immunodeficiency virus (HIV)1/2-antibodies, Hepatitis B surface (HBs)-antigen, Hepatitis B core (HBc)-antibodies, Hepatitis C virus (HCV)-antibodies determined at screening examination.
- Negative drug abuse screening test determined at screening examination (the test will include screening for metamphetamine, opiate, cannabis, cocaine, amphetamine and benzodiazepine).
- Negative beta-human chorion gonadotropin test for females of childbearing potential determined at screening examination (the test is not necessary in females who are in post-menopausal state for at least 2 years or in females with status after surgical sterilisation).
- The participant must be able to tolerate the cold pressor test, i.e. he/she must be able to keep his/her hand for 120 seconds in cold water of about 2 degrees celsius.
- The participant must be able to undergo the procedure of pupillometry.
Exclusion Criteria:
- Pulse rate below 45 or above 100 Beats per minute (bpm). The measurement must be performed in supine position after a resting period of at least 5 minutes.
- Systolic blood pressure below 100 or above 160 Millimeter mercury (mmHg), diastolic blood pressure below 50 or above 100 mmHg. The measurement must be performed in supine position after a resting period of at least 5 minutes.
- History or presence of diseases or functional disorders of the Central nervous system (CNS), endocrinological system, gastrointestinal tract, hepatobiliary system, renal system, respiratory system or cardiovascular system or other conditions known to interfere with the absorption, distribution, metabolism or excretion of drugs.
- Marked repolarisation abnormality (e.g. suspicious or definite congenital long QT syndrome) or co-medication that is known to influence cardiac repolarisation substantially.
- History of seizures or at risk (epilepsy in family anamnesis, unclear loss of consciousness), head trauma requiring hospitalization.
- Neurotic personality, psychiatric illness or suicide risk.
- History of orthostatic hypotension.
- Bronchial asthma.
- Definite or suspected history of drug allergy or hypersensitivity.
- History of Raynaud´s disease or phenomenon.

- Blood donation (more than 100 Milliliter(s) or a comparable blood loss within three month prior to the start of this study.
- Excessive consumption of food or beverages containing caffeine or other xanthines (more than 1000 Milliliter(s) coffee or equivalent per day) within two weeks prior to the start of this study.
- Evidence of alcohol, medication or drug abuse.
- Smokers who are not able to abstain from smoking during the hospitalisation.
- Intake of drugs that are inhibitors of CYP2D6 isoenzyme within the last 4 weeks prior to the start of this study. Use of any other medication within two weeks prior to the start of the study (self-medication or prescription), if not on a stable basis and known to interfere with study objectives.
- Known or suspected of not being able to comply with the study protocol or of not being able to communicate meaningfully with the investigator and staff.
- Opinion of the investigator the volunteer should not participate in the study.
