Patent ID: 8809615

Claim:
An adhesive preparation comprising: a stretchable support and an adhesive layer, wherein the adhesive layer is laminated on at least one side of the support and comprises a thermoplastic elastomer, and 10% by mass or more of methyl salicylate with respect to the total mass of the layer, wherein the whole adhesive preparation has moisture permeability of 1 to 350 g/m 2 ·24 hr measured at a temperature of 40° C. and a relative humidity of 90%, and wherein the methyl salicylate has a plasma AUC 0-24 per unit area ranging from 1.0×10 −2 to 2.1×10 −1 ng·hr/mL/cm 2 in terms of a mean±standard deviation, and a salicylic acid as a metabolite of the methyl salicylate has a plasma AUC 0-24 per unit area ranging from 17.8 to 46.4 ng·hr/mL/cm 2 in terms of a mean±standard deviation, when the adhesive preparation is applied to a human skin for 8 hours such that an application amount of the adhesive layer is 50 to 300 g/m 2 .
