N2 - A genuine peripheral antinociceptive and anti-inflammatory effect of Botulinum neurotoxin type A (BoNT/A) has been proposed but could not be demonstrated in humans so far. Therefore, 100 mouse units of Botulinum toxin A (Dysport) and placebo were injected in a double blind paradigm in defined skin areas of 50 subjects. At baseline and after 4 and 8 weeks allodynia was induced in the skin areas with capsaicin ointment. Heat and cold pain threshold temperatures were measured with quantitative sensory testing, and threshold intensities upon electrical stimulation with a pain specific surface electrode were determined. No BoNT/A related differences in pain perception were found at any quality. There is neither a direct peripheral antinociceptive effect nor a significant effect against neurogenic inflammation of BoNT/A in humans.
