Abstract: A method for producing a patch comprising a support layer and an adhesive agent layer comprises: a mixture preparation step of mixing asenapine or a pharmaceutically acceptable salt thereof with sodium acetate whose particle diameter D50 at a cumulative volume of 50% in a particle diameter distribution is 40 to 1000 μm, in such a manner that the sodium acetate and sodium diacetate generated from the sodium acetate have a particle diameter D50 of 10 μm or smaller, thereby obtaining a mixture containing the sodium diacetate and the asenapine or pharmaceutically acceptable salt; and an adhesive-agent-layer formation step of forming the adhesive agent layer comprising the sodium diacetate, the asenapine or pharmaceutically acceptable salt, and a pressure-sensitive adhesive base agent, by using an adhesive agent layer composition obtained by mixing the mixture with the pressure-sensitive adhesive base agent.

Abstract: A patch for administering asenapine includes a support layer, and an adhesive agent layer formed on the support layer and including an adhesive base agent and asenapine and/or a pharmaceutically acceptable salt thereof. The adhesive base agent has a content in a range of 10 to 90% by mass in the adhesive agent layer and includes a natural rubber, polyisobutylene, an alkyl vinyl ether(co)polymer, polyisoprene, polybutadiene, a styrene-butadiene copolymer, a styrene-isoprene copolymer, a styrene-isoprene-styrene block copolymer, or a combination thereof. When a content of the asenapine and/or pharmaceutically acceptable salt thereof in terms of free asenapine in the adhesive agent layer is 3.4 mg, an AUC2-120 for a period starting from the time when the patch is brought into contact with a skin for 24 hours is 27,000 pg·hr/mL or more, and an AUC2-120 of an asenapine metabolite is 20% or less of the AUC2-120 of the free asenapine.
