Toplcal capsalcin treatment is known to deplete neuropeptides released from cutaneous sensory nerves We studled the effect of topical capsalcin on primary irritant dermatitis and allergic contact sensitivity in mice. Capsaicin pretreatment caused signlflcant inhlbition of ear swelling as pnmary irritation induced by toplcal application with croton oil. In contrast, capsaicin pretreatment had no Inhibitory effect on allergic contact hypersensitivity reaction to oxazolone These results Indicate that neuropeptides in sensory nerves are Involved In the pathogenesis of primary irritant dermatitis, but not in allergic contact dermatitis.
