The subject is 65 years to 75years of age 5. The subject has a BMI 19 kg/m2 and 30 kg/m2 at the Screening Visit 6. The subject has normal vital signs after resting for 5 minutes in supine position pulse and heart rate as recorded on the ECG: 51 bpm and 100 bpm systolic blood pressure: 91 mmHg and 150 mmHg diastolic blood pressure: 51 mmHg and 90 mmHg 7. The subject has normal 12-lead ECG after 10 minutes resting in supine position (in particular QTc < 450 ms) 8. The subject has an orthostatic blood pressure <20 mmHg (based on the difference between supine and standing [1 minute] systolic blood pressure). 9. The subject has clinical laboratory test values within the reference ranges. Borderline values may be accepted if they are, in the opinion of the investigator, not clinically relevant 10. The subject has a normal circadian rhythm, defined as a person who usually wakes between 06:00 and 09:00 and goes to sleep between 21:00 and 24:00 11. The subject is, in the opinion of the investigator, generally healthy based on assessment of medical history, physical examination, vital signs, ECG, and the results of the haematology, clinical chemistry, urinalysis, serology, and other laboratory tests 12. The subject is covered by a Health Insurance System where applicable, and in compliance with the recommendations of national laws in force relating to biomedical research 13. The subject is not under any administrative or legal supervision.

E.4 | Principal exclusion criteria |
1. The subject has taken disallowed medication within 1 week prior to the first dose of IMP (or within 5 half-lives prior to baseline for any medication ingested, whichever is longer). Disallowed medication is any prescribed medication or over-the-counter (OTC) medication as well as any herbal medicine known to interfere with the metabolic CYP pathways, such as St. John’s Wort (except for hormonal contraceptives or hormonal substitution therapy). Subjects who have taken any non-prescribed systemic or topical medication may still be entered into the study if, in the opinion of the investigator, the medication will not interfere with the study procedures, study results, or compromise safety. 2. The subject weight >136 kg. 3. The subject cannot stand erect and unsupported for more than 2 to 3 minutes or loses balance when standing on a fixed surface with eyes open. 4. The subject has an excessive consumption of beverages on xanthine bases (more than 4 cups or glasses daily). 5. The subject has a presence or history of alcohol abuse defined as alcohol consumption greater than 21 units per week for men and greater than 14 units per week for women (a unit of alcohol is defined as 250 mL of lager/beer, 100 mL of wine, or 25 mL of spirits); or a presence or history of drug abuse within the last 6 months, or a history of substance abuse deemed relevant by the investigator. 6. The subject has taken any investigational products within 3 months prior to baseline. 7. The subject has taken the IMPs earlier in this clinical study. 8. The subject has participated in a previous clinical study with any of the IMPs 9. The subject has known hypersensitivity to the IMP, zolpidem or their excipients. 10. The subject has a history of severe drug allergy or hypersensitivity. 11. The subject has a presence or history of sleep disorder, fainting, cardiovascular diseases, carotid sinus syndrome, relevant dizziness or arrhythmia. 12. The subject is a regular user (used more than once in a week) of hypnotics, tranquiliers or other drugs to induce sleep. 13. The subject has a history of or presence of any clinically relevant immunological, cardiovascular, pulmonary, metabolic, renal, hepatic, gastrointestinal, endocrinological, haematological, dermatological, venereal, neurological, systemic, ocular or psychiatric or infectious disease or other major disorder, or sign of acute illness. 16. The subject has any concurrent illness that may affect the particular target or the metabolism of the IMPs. 17. The subject has had a clinically relevant illness within 4 weeks before the first dose of IMP. 18. The subject has had surgery or trauma with notable blood loss within the last 3 months before the first dose of IMP. 19. The subject has donated blood within 1 month before the first dose of IMP. 20. The subject has tested positive for anti-human immunodeficiency virus (HIV) 1 and 2 antibodies; hepatitis B surface antigen (HBsAg), or anti-hepatitis C virus antibody (anti-HCV-Ab). 21. The subject’s QTc (Bazett’s or Fridericia’s correction) is >450 ms (at the Screening Visit or at the Safety Baseline Visit) as read on the printout of the ECG produced by the ECG equipment and evaluated by the investigator. 22. The subject smokes more than 10 cigarettes daily or uses equivalent of other nicotine-containing products (such as snuff, nicotine patch, nicotine chewing gum, mock cigarette, inhaler, pipe). 23. The subject has tested positive at the Screening Visit or at the day of admission in each Dosing Period (Day 1, 8 and 15) for drugs of abuse (opiates, methadone, cocaine, amphetamines/methamphetamines (including ecstasy), barbiturates, benzodiazepines and cannabinoids). 24. The subject has tested positive at the Screening Visit or at the day of admission in each Dosing Period (Day 1, 8 and 15) for alcohol. 25.
