Further study details as provided by Capital District Health Authority, Canada:

Primary Outcome Measures:
  • change in visual rating of skin response (redness and oedema) [ Time Frame: ratings made at 3, 6, 9 and 12 minutes after application of methyl nicotinate ] [ Designated as safety issue: No ]
    A 7-point visual rating scale, previously tested for reliability (Kerr 2008), to visually rate the skin response to aqueous methyl nicotinate (niacin) with respect to both redness and oedema as a function of increasing niacin concentrations.Ratings will be acquired every three minutes over a 12-minute period starting at the time of solution application.

Estimated Enrollment: 200
Study Start Date: December 2011
Estimated Study Completion Date: June 2015
Estimated Primary Completion Date: December 2014 (Final data collection date for primary outcome measure)
Intervention Details:
    Other: skin test
    four patches of 2 x 3cm thin blotting paper will be soaked with an equivalent amount (0.1 mL) of aqueous methyl nicotinate in four different concentrations: 0.1, 0.01, 0.001, 0.0001 M. The four patches will then be applied at the same time to the inner forearm for 60 seconds.
