Abstract:
The present invention relates to a nalfurafine-containing percutaneous absorption patch having a support, a drug layer and a control layer which are laminated successively, wherein the drug layer contains at least one kind of a drug selected from the group consisting of nalfurafine and a salt thereof, and capable of maintaining a given level of drug skin permeation amount without permeation of an excess amount of the drug through the skin in a short time even when applied to the skin in which the horny cell layer and the like are damaged and the skin barrier is insufficient.

Claim (Index 14):
The percutaneous absorption patch according to  claim 5  wherein, in a rat skin permeation test, a ratio of the drug skin permeation amount per unit time 10 hr later to the maximum value of the drug skin permeation amount per unit time (drug skin permeation amount per unit time 10 hr later/maximum value of drug skin permeation amount per unit time) is not less than 0.5.
