Zusammenfassung: | The invention relates to a patch system for transdermal absorption, which comprises: (a) an outer protective layer; (b) a solvent-type adhesive layer; (c) a non-solvent-type adhesive layer; and (d) arelease layer. The release layer is a film that is removed before use. The solvent-type adhesive layer is adjacent to the outer protective layer, and the non-solvent-type adhesive layer is adjacent tothe release layer and is in contact with skin when applied to the skin. The solvent-type adhesive layer and/or the non-solvent-type adhesive layer include one or more components selected from the group consisting of skin active ingredients and pharmaceutically active ingredients. Skin irritation is minimized when the patch system applied to skin of a human body while percutaneous absorption of various active components is efficiently enabled.
