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.
摘要:
The invention provides a patch preparation containing (a) a support and (b) an adhesive layer containing a drug on the surface of the support, wherein a crystal of the drug is formed in the adhesive layer immediately after application of a physical stimulation to the adhesive layer, while a crystal of the drug is formed during preservation after the physical stimulation. The patch preparation which does not require an increase in the area and thickness of an adhesive layer, achieves a sufficiently high skin permeation amount of the drug, shows good adhesiveness to skin, and permits a long-term adhesion to skin. The invention also provides a method of producing the patch preparation.
