Secondary outcome [1] 311770 0
Safety: Adverse events reporting, visual nasal mucosal examination and healthy screen pre- and post-study

Healthy screen includes: Physical examination, including vital signs (blood pressure, heart rate, respiratory rate and temperature) and ECG. Urinalysis for general health (urine pH, blood, protein, ketones, leukocyte elastase, nitrates, glucose, Specific gravity, urobilinogen and bilirubin) and any drugs of addiction*. Blood collected for clinical laboratory analysis (serum chemistry and haematology) and analysis for HIV*, hepatitis B*, and hepatitis C* analysis. Normal ranges for clinical laboratory parameters will be as per the local laboratory definitions.
Timepoint [1] 311770 0
Visual nasal mucosal examination at screening, check-in, day 4 (pre-nasal-dose) and day 5 (24 hours post-nasal-dose).

Adverse events are monitored from Day 1 until Day 5 (24 hours post-nasal-dose) and at follow-up visit (Day 9 +/- 1).

Healthy screens are undertaken at screening, admission (Day -1) and on Day 5 (24 hours post-nasal-dose).

Brief summary
Rivastigmine (RIV) is an acetylcholine esterase inhibitor which prevents neurotransmitter breakdown. As such it is currently approved for the treatment of neurological disorders such as Alzheimer's and Parkinson's disease. RIV is available in two forms, oral (capsule and liquid) and as a transdermal (through the skin) patch. The latter was developed as a consequence of the oral forms causing nausea, vomiting and diarrhoea predominantly caused by the low oral bioavailability of this drug. Although the transdermal patch overcomes a lot of these side effects, a high percentage of people suffer from skin irritation and possible sleeplessness. This study will investigate whether delivering RIV intranasally (into the nose), results in lower side effects, while maintaining the desired therapeutic effect. As such this study will compare the bioavailability of intranasal delivery to intravenous delivery of RIV at a level that is reported to be therapeutically beneficial. Each intervention will be as a single dose with thorough blood sampling over 24 hours to assess drug levels; each intervention will be separated by a 2 day washout period. This is an exploratory phase 1 trial in 8 healthy elderly males and females aged 55 to 85 years. While comparing the two delivery methods, this study will also investigate the safety and tolerability of intranasal Rivastigmine.
