Document Type and Number:
Japanese Patent JP6139005
Kind Code:
B2
Abstract:
A transdermal absorption sheet and a manufacturing method for the transdermal absorption sheet includes a laminating step of forming a multilayer film with a viscosity difference by forming, on a support, a lower layer containing a first transdermal absorption material and an upper layer containing a drug and a second transdermal absorption material and having a lower viscosity than the lower layer, a filling step of filling needle-like recessed portions corresponding to inverted needle-like protruding portions with a solution of the transdermal absorption material by pressing a mold in which the needle-like recessed portions are arranged in a two-dimensional array, against a surface of the multilayer film supported by the support to allow the multilayer film to flow, a solidifying step of solidifying the multilayer film with the mold pressed against the surface of the multilayer film, and a peeling-off step of peeling the solidified multilayer film from the mold.
