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.
