ABSTRACT:
A percutaneous absorption type patch adapted to be applied to a skin surface of a patient. The percutaneous absorption type patch comprises: a stratum-corneum release member constituted from a sheet-like first supporting substrate and a pressure-sensitive adhesive layer laminated on the first supporting member; a medicinal-components administration member constituted from a sheet-like second supporting substrate, a medicinal-components retention layer laminated on the second supporting substrate, and a protect layer laminated on the medicinal-components retention layer; and a sheet-like handling member interposed between the stratum-corneum release member and the medicinal-components administration member. An edge portion of the handling member is coupled to or integrated with both the first supporting substrate and the protect layer. Operations of peeling the stratum-corneum release member from the skin surface of the patient and peeling the protect layer from the medicinal-components retention layer are carried out at a time by pulling the handling member toward an operating direction.
