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: 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: 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.
