- Intractable Disease Information Center which is jointly operated by the Ministry of Health, Labor and Welfare, Health Bureau, Disease Control Division and the Foundation for Research on Intractable Diseases.
- Non-Patent Document 2 One of the sensory disorders is severe itching (pruritus), which occurs when there is a disorder in the dorsal horn of the spinal cord (for example, Non-Patent Document 2).
- This itch is characterized by a few minutes of itch appearing several times a day.
- the site of itching is relatively bilateral, according to the segments of nerve branches such as the cervical and thoracic nerves.
- the feeling of itching is an unbearable itching after being stabbed by a small insect, and when it appears at night, it disturbs sleep (for example, Non-Patent Document 3). There is no rash on the skin, but sometimes the skin is eroded by intense whispering power.
- Non-Patent Document 5 Dermatologists express itch that does not stop even if they crawl, and itch that can be destroyed by self-injury, as a strange symptom (for example, Non-Patent Document 2).
- Opioid ⁇ having 4,5-epoxymorphinan skeleton Receptor agonist compounds include, for example, atopic dermatitis, neurodermatitis, contact dermatitis, seborrheic dermatitis, self-sensitizing dermatitis, caterpillar dermatitis, sebum deficiency, senile skin pruritus Dermatosis, insect bites, photosensitivity, urticaria, urticaria, shingles, impetigo, eczema, ringworm, lichen, psoriasis, scabies, acne vulgaris, and malignant tumors, diabetes, liver disease, It has been reported that it can be an antidiarrheal agent for the treatment of general pruritus such as renal failure, renal dialysis, and visceral diseases such as pregnancy (
- opioid ⁇ -receptor activity is not a cause of multiple sclerosis, which is caused by a neurological disease, not a skin disease or a medical disease, and whose characteristics and treatment are greatly different from those of normal itch. It was unclear whether the compound was effective.

- the ability to suppress the pulling behavior was evaluated.
- the evaluation was divided into 5 days, and on the first day, sterilized distilled water was orally administered 30 minutes before the start of shooting of the pulling behavior, and the number of pulling behaviors at the time of solvent administration was measured for 60 minutes.
