Abstract Assessments were made of cutaneous responses to topically applied methyl-nicotinate (93607) (MN) on black, oriental, and Caucasian subjects to determine if racial differences had any part to play in percutaneous absorption and microcirculatory sensitivity. Both visual and laser Doppler velocimetry evaluations were made of the MN induced vasodilatation. Specific assessment was made of the diameter of the maximum visually perceptible erythematous area, the area under the erythematous diameter versus time curve, the maximum laser Doppler velocimetry response, and the area under the laser Doppler velocimetry response versus time curve. For all subjects each of the measures was dependent on the dose of MN applied with the exception of the maximum laser Doppler velocimetry response. The authors conclude that although some racial differences did appear to exist in response to topical MN, the perception of these distinctions may depend on the method of measurement.
