| 摘要 |
The present invention provides an adhesive patch including a backing and a pressure-sensitive adhesive layer formed on at least one surface of the backing, in which (a) a surface of the pressure-sensitive adhesive layer has a logarithmic decrement, as determined by the rigid-pendulum free-damped oscillation method, in the range of 0.03 to 0.35, and (b) the pressure-sensitive adhesive layer has a maximum shear displacement in the range of 18 µm to 1,000 µm. The present invention further provides a patch preparation containing a drug. The adhesive patch and the patch preparation according to the present invention are reduced in skin irritation during wear. |
