Outcomes
Primary outcome [1] 321715 0
Pharmacokinetics: Cmax, tmax, AUC0-last, AUC0-infinity, t1/2 and terminal elimination rate constant,

Plasma assay for rivastigmine and its' primary metabolite (NAP 226-90) and pharmacokinetic parameters calculated using noncompartmental pharmacokinetic analysis. Inferential statistics on the natural log-transformed (ln) pharmacokinetic parameters (Cmax, AUC0-last, AUC0-infinity) will be performed using the 3mg oral dose as reference.
Timepoint [1] 321715 0
Nasal: Pre-dose, 5, 10, 15, 30, 45, 60, 90 mins; 2, 3, 4, 6, 8, 10, 12 and 24 h
Oral: Pre-dose, 15, 30, 45, 60, 90 mins; 2, 3, 4, 6, 8, 10, 12, 15 and 24 h
Secondary outcome [1] 375995 0
Safety: Adverse events reporting, visual nasal mucosal examination and healthy screen pre- and poststudy.

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.
*Pre-study
Timepoint [1] 375995 0
Visual nasal mucosal examination at screening, check-in, pre-nasal-dose and 24 hours postnasal-dose.
Adverse events are monitored from Day 1 until Day 5 (24 hours post-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-dose).

Summary
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 dementia. RIV is available in two forms, oral (capsule) 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 nasally (into the nose) provides RIV therapeutic levels in the blood plasma that are comparable to Exelon (Registered Trademark) oral capsule and whether nasal RIV results in lower side effects. 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 a phase 1 trial in 16 young healthy males aged 18 to 55 years. While comparing the two delivery methods, this study will also investigate the safety and tolerability of Rivastigmine nasal spray.
