Induces release of substance P, the principal chemomediator of pain impulses
from the periphery to the CNS, from peripheral sensory neurons; after repeated
application, capsaicin depletes the neuron of substance P and prevents
reaccumulation |

Usual Dosage |

Children greater than or equal to 2 years and Adults: Topical: Apply to
affected area at least 3-4 times/day; application frequency less than 3-4
times/day prevents the total depletion, inhibition of synthesis, and transport
of substance P resulting in decreased clinical efficacy and increased local
discomfort |
