"Repeated application of topical capsaicin causes depletion of SP from sensory nerve endings and abolishes pain and itch (Fitzgerald, 1983; Wallengren and Moller, 1986; Lynn, 1992)."

"In addition, creams containing local anesthetics [XREF_BIBR], capsaicin, doxepin [XREF_BIBR], strontium nitrate [XREF_BIBR], or nedocromil sodium [XREF_BIBR] can be helpful to relieve itch."

reach
"With repeated topical applications, capsaicin not only reduces the magnitude of chemically evoked itch and nociceptive sensations [XREF_BIBR] but also attenuates the itch mediated by an intradermal injection of histamine and abolishes the itch elicited by cowhage [XREF_BIBR]."

reach
"To ablate the TRPV1- and TRPV1- and TRPA1-positive sensory neurons, we used the super potent capsaicin analogue resiniferatoxin (RTX), which has been shown to suppress acute pain and itch in animal models via axonopathy."

reach
"Itch evoked by cowhage or histamine is reduced or blocked by capsaicin desensitization, suggesting that pruriceptive neurons are capsaicin sensitive."

"Topical Capsaicin in Poly(lactic-co-glycolic)acid (PLGA) Nanoparticles Decreases Acute Itch and Heat Pain."
