Abstract: Provided is a dexmedetomidine-containing non-aqueous external preparation being capable of suppressing the precipitation of a crystal of dexmedetomidine in the preparation, and having satisfactory transdermal absorbability. The non-aqueous external preparation includes: (A) dexmedetomidine or a salt thereof; (B) an aliphatic alcohol having 10 to 12 carbon atoms; (C) a propylene glycol monoester of a fatty acid having 6 to 16 carbon atoms; (D) an organic acid; and (E) an organic acid salt.

Abstract: Provided is a patch providing sufficiently high absorbability of dexmedetomidine and less skin irritation. Hydrous adhesive patch comprising dexmedetomidine or a salt thereof and a water-soluble polymer.

Abstract: Provided is an intraoral soluble-type film preparation in which an unpleasant taste of a drug is masked. The intraoral soluble-type film preparation comprises a drug layer containing: a drug having a bitter taste and/or an astringent taste; an alkyl sulfate at a content of ¾ mol or more with respect to 1 mol of the drug; and a water-soluble polymer.

Abstract: In pressure bonding edible layers having irregular surfaces due to the presence of aggregated substance so that the irregular surfaces face each other, an edible layer substantially free of any aggregated substance is interposed therebetween. This allows an orally administrable edible agent of aggregated substance-containing laminate film form having a multilayer structure including laminated extremely thin layers to be produced. The multilayer structure by such a pressure bonding technique can satisfy quantitative accuracy required for pharmaceutical preparations, and prevents time constraint in a drying step or the like, thereby providing a producing method with high productivity.

Abstract: Provided is a film preparation in which an unpleasant taste derived from a medicament is masked. The film preparation includes coating layers containing no terpene formed on both sides of a medicament-containing layer containing a medicament having an unpleasant taste and a terpene.

Abstract: Two resin films each provided with an orally administrable edible agent layer are joined so that administrable agent layers face each other, drawn into a nip between a pair of press rolls, pressurized at back surfaces to bond the administrable agent layers together, and conveyed in a direction substantially conforming to a tangential direction at a pressurization zone of the press rolls. A delamination roll disposed in the conveying direction is used to draw only one of the two resin films sandwiching the bonded plural administrable agent layers in a direction different from the conveying direction, while continuously conveying the other resin film retaining the plural administrable agent layers in the conveying direction. This allows only one of the joined two resin films to be delaminated. The obtained pressure bonded product, that is, an orally administrable edible agent of laminate film form can be punched out into predetermined shapes.

Abstract: The film preparation of the present invention includes: a drug-containing intermediate layer containing loperamide hydrochloride, a terpene and a film-forming agent; and coating layers containing a film-forming agent and a plasticizer (but not a terpene) and laminated on both sides of the drug-containing intermediate layer. As a bitter taste derived from loperamide hydrochloride is thereby masked, uncomfortable sensation when taking the film preparation can be reduced. Furthermore, as this film preparation is rapidly dissolved (i.e., has a rapidly dissolving property) only with moisture in the oral cavity, it begins to work quickly and is very convenient when it is carried and taken.
