BACKGROUND OF THE INVENTION Pruritus, typified by atopic dermatitis, has a complicated expression mechanism, and many parts thereof have not yet been elucidated. In addition, the number of pruritus patients has increased remarkably in recent years, possibly due to the significant change in lifestyle patterns. However, the therapeutic mechanism is not established because there are many unclear mechanisms, and antihistamines and steroids, which are highly effective against inflammation, have little effect on atopic dermatitis. That is, the development of a skin external preparation effective for pruritus typified by atopic dermatitis has been awaited.

Example 4 Test Example The antipruritic effect was examined using male ddy mice. That is, 5-hydroxytryptamine (5H
Pruritus was induced by intradermal injection of T) at 30 μg / 50 μl / site. When the drug administration group was administered 5HT,
0.05 ml of the lint cloth part of the patch adhesive plaster for patch test was impregnated with the external skin preparation of 3 in a closed test for 24 hours. Comparative group 1 is 0.1% of 5HT antagonist 3
0.05 ml of physiological saline solution is closed patch,
In Comparative Example 2, 0.1% of 5HT antagonist 3 was administered at the time of 5HT administration.
Saline solution was administered by 50 μl intradermal injection. In the control group, only physiological saline was administered by intradermal injection in an amount of 50 μl instead of the physiological saline solution of the drug. 4 after administration
The number of scratching behaviors of the animals was counted for 0 minutes. Table 2 shows the results
Shown in From this, it can be seen that the external preparation for skin of the present invention is excellent in suppressing the number of scratching behaviors as compared with intradermal administration and simple closed patch administration of physiological saline solution, and is an effective preparation against pruritus. . Further, upon transdermal administration of the external preparation for skin of the present invention by a closed patch, no reaction unfavorable for safety such as occurrence of inflammation or edema was exhibited. Therefore, it is understood that the external preparation for skin of the present invention is excellent in safety. Further, comparing the skin external preparations of the present invention with each other, it can be seen that the inhibitory effect also increases as the amount of ethanol, which is a low chain length alcohol, increases.
