Can healthy volunteers participate?
Key exclusion criteria
1. Renal impairment as evidenced by estimated creatinine clearance (CrCl), measured by
the Cockcroft-Gault method, of less than 90 mL/min.

2. Have a laboratory value at the Screening Visit that is outside the normal range,
unless it is judged by the Investigator as not clinically significant after
appropriate evaluation.

3. A score of more than two standard deviations from the mean on any of the key nine
scales in the SCL-90-R ®

4. Any medical condition that in the opinion of the Investigator may adversely impact on
the participant's ability to complete the study, including but not limited to:

- History of cerebral trauma or stroke

- History of seizure or epilepsy

- Hyperthyroidism

- Recent clinically significant URTI (within two weeks of Day 1) or respiratory

- History of Myocardial Infarction or clinically significant cardiac disease
including cardiac arrhythmia.

- Poorly controlled hypertension - as assessed by the Principal Investigator.

- Clinically significant history of asthma requiring regular supportive or
preventative therapy (childhood asthma that has resolved >5 years previously may
be suitable for inclusion at the discretion of the Investigator.

including anxiety, psychosis or depression.

9. Concurrent use of other medication on a regular or daily basis including but not
limited to, theophylline, benzodiazepines, thyroxine, sedatives or anti-anxiolytics.

or human immunodeficiency virus (HIV).

12. Clinically significant abnormal ECG (12-lead) at the screening visit or prior to
dosing on Day 1, as determined by the Investigator.

13. Participants who have a marked prolongation of the QT corrected (QTc) interval (i.e.,
repeated demonstration of a QTc >430 msec for males) at screening or prior to dosing
on Day 1 in either study period will not be allowed to continue in the study.

14. Significant history of illicit drug or alcohol use or abuse (as determined by the
Principal Investigator).

15. Any alcohol use within 24 hours prior to dosing on Day 1 in each of the study periods.

16. Unwillingness or inability to comply with the requirements of this protocol, including
the presence of any condition (physical, mental, or social) that is likely to affect
the participant returning for follow-up visits on schedule.

17. Blood donation (1 unit or more) within 1 month prior to the screening visit.

18. Current or previous tobacco user (within 12 months prior to Day 1) .

19. Planned surgical procedure requiring general anaesthesia during the study period and
