摘要： A non-aqueous patch preparation may include a drug solution in which a drug is dissolved in an organic solvent, a lipophilic mass base, and anhydrous silicic acid powders that are insoluble both in the organic solvent and in the lipophilic mass base. The organic solvent is selected from the group consisting of propylene glycol, 1,3-butanediol, polyethylene glycol, and propylene carbonate. The lipophilic mass base comprises an elastomer, a tackifier, and a softening agent wherein the elastomer is styrene-isoprene-styrene copolymer (SIS). The patch preparation has 2% to 10% by weight of the anhydrous silicic acid powders.

摘要： Provided are a method of applying a microneedle array, and a patch or an assistant tool used therefor. When skin is to be stretched and punctured with microneedles, the microneedle array can be prevented from detaching from the skin by providing adhesive layers, with the microneedle array therebetween, in a direction different from the direction in which the skin is stretched. Additionally, the application method can be appropriately implemented by producing a patch or an assistant tool having a rigid flat plate. As a result, the microneedle array can be punctured more accurately with less stress.

摘要： The purpose of the present invention is to provide a nonaqueous tape that is stable and has high percutaneous absorption performance, and that contains pramipexole hydrochloride, which is slightly soluble in organic solvents and has high crystallinity. The present invention could produce a nonaqueous tape that is stable and has high percutaneous absorption performance by dissolving pramipexole, using a combination of a fatty acid ionic liquid and a divalent alcohol and a fatty acid ester. As a result, it has become possible to provide a transdermal patch (tape) containing pramipexole for the treatment of Parkinson's disease with which the problems associated with a conventional water-containing poultice of discoloration of the preparation and stability of the pramipexole can be solved.
