Patent Application
20120328675
The present invention relates to a film preparation in which an unpleasant taste of a medicament is masked, a method for producing the same, and a method for masking an unpleasant taste in a film preparation containing a medicament having an unpleasant taste.
In recent years, various film preparations have been studied and developed as pharmaceutical dosage forms which are convenient when they are carried (Patent Document 1). Convenience of carrying pharmaceuticals is a great advantage because it leads to easiness of taking the pharmaceuticals when outside the home, for example, and further leads to improvement of compliance with taking the pharmaceuticals. In particular, a film preparation which is dissolved in the oral cavity can be taken without water and hence can be taken even in a situation where taking with water is difficult, such as during commuting or meeting. Therefore, such a preparation is particularly useful. However, in the case of a film preparation containing a medicament having an unpleasant taste such as a bitter taste, a harsh taste, or an astringent taste, a bad sensation upon taking the preparation based on the unpleasant taste causes, for example, rejection of taking the preparation by a patient, resulting in significant deterioration of the advantage of the film preparation, i.e., good compliance with taking the preparation. Therefore, various studies have been made on a technology for masking an unpleasant taste of the film preparation containing a medicament having an unpleasant taste.
As the technology for masking an unpleasant taste in the film preparation, there have been reported, for example, a technology involving for blending a flavoring agent such as an ion-exchange resin (Patent Document 2) and a technology involving providing a water-swellable gel-forming layer as an outermost layer in a film preparation including a medicament-containing layer and a water-swellable gel-forming layer (Patent Document 3).
However, all the conventional film preparations have insufficient masking effects.
The present invention is to provide a film preparation in which an unpleasant taste derived from a medicament is masked.
The inventors of the present invention have conducted various researches to achieve the foregoing object, and they have surprisingly found that a noticeable effect of masking an unpleasant taste of a medicament is exerted by a film preparation including coating layers containing no terpene formed on both sides of a medicament-containing layer containing a medicament having an unpleasant taste and a terpene. Thus, the present invention has been accomplished.
That is, the present invention provides a film preparation, including coating layers containing no terpene formed on both sides of a medicament-containing layer containing a medicament having an unpleasant taste and a terpene.
The present invention also provides a method for masking an unpleasant taste in a film preparation containing a medicament having an unpleasant taste, the method including forming coating layers containing no terpene on both sides of a medicament-containing layer containing a medicament having an unpleasant taste and a terpene.
The present invention also provides a method for producing a film preparation in which an unpleasant taste derived from a medicament having an unpleasant taste is masked, the method including the step of forming coating layers containing no terpene on both sides of a medicament-containing layer containing a medicament having an unpleasant taste and a terpene.
The film preparation of the present invention can reduce a bad sensation of taking the preparation, because an unpleasant taste derived from a medicament is masked.
A film preparation of the present invention is a multi-layer film preparation including “coating layers” formed on both sides of a “medicament-containing layer” containing a medicament having an unpleasant taste. The “medicament-containing layer” contains the medicament having an unpleasant taste and a terpene, while the “coating layer” is characterized by containing no terpene. It should be noted that, in the present invention, the term “coating layer” means a layer containing no medicament having an unpleasant taste (that is, a layer other than the “medicament-containing layer”). Therefore, the film preparation of the present invention is a film preparation which includes coating layers formed on both sides of a medicament-containing layer containing a medicament having an unpleasant taste and contains a terpene only in the medicament-containing layer.

Specific forms of the film preparation of the present invention (such as the number and sizes of layers) are not particularly limited so long as the preparation includes coating layers on both sides of a medicament-containing layer.
Specifically, the film preparation of the present invention may have a form including coating layers laminated on both sides of a medicament-containing layer, such as a laminated three-layer form including the coating layer, the medicament-containing layer, and the coating layer, laminated in this order (
Further, in the present invention, when layers of the same type are laminated adjacent to each other, they are integrated to each other to exert the same function. In the present invention, these layers are therefore regarded as substantially one layer (for example, a laminated four-layer structure including the coating layer, the medicament-containing layer, the medicament-containing layer, and the coating layer is taken as synonymous with a laminated three-layer structure including the coating layer, the medicament-containing layer, and the coating layer). Therefore, also in a form obtained by laminating the coating layer only on one side of the medicament-containing layer and folding the resultant into two such that the medicament-containing layer is provided inside (
In addition, the sizes (areas) of the medicament-containing layer and the coating layer may be identical to or different from each other. The film preparation of the present invention includes a form including the medicament-containing layer which is smaller than the coating layers (
It should be noted that the form of the film preparation of the present invention is not limited to the specific forms illustrated in
The thickness of the whole film preparation is not particularly limited, but is preferably 30 to 300 μm, particularly preferably 30 to 200 μm. In this case, the thickness of the coating layer is preferably 5 to 100 μm, particularly preferably 10 to 50 μm. The thickness of the medicament-containing layer is preferably 10 to 200 μm, particularly preferably 10 to 100 μm. With this, the preparation can be rapidly dissolved in the oral cavity. Further, the size of the film preparation of the present invention is not particularly limited so long as it is easily taken. For example, a size of approx. 0.5 to 10 cm2 is preferred. The shape is not particularly limited either so long as it is easily taken. For example, a rectangular shape, a circular shape, or an elliptical shape may be suitably selected.
The film preparation of the present invention may be suitably prepared by common or known methods. For example, the film preparation of the present invention may be prepared by laminating a first coating layer on a release film made of polyethylene terephthalate (PET) or the like, laminating a medicament-containing layer thereon, and then laminating a second coating layer on the medicament-containing layer. Alternatively, the film preparation of the present invention may also be prepared by separately preparing an interim product obtained by laminating a first coating layer on a release film and further laminating a medicament-containing layer thereon, and an interim product prepared by laminating a second coating layer on a release film and further laminating a medicament-containing layer thereon, and then attaching the medicament-containing layers of both interim products so that they are opposed to each other and laminating them by pressure. It should be noted that the film-forming agents in the first coating layer and the second coating layer may be identical to or different from each other.
The film preparation of the present invention is preferably administered orally (that is, the preparation is preferably “film preparation for oral administration”). In particular, the film preparation of the present invention is particularly preferably produced as a film preparation which is dissolved in the oral cavity because a bad sensation when taking the film preparation can be reduced, and the preparation can be dissolved only with moisture in the oral cavity and hence can be easily taken. It should be noted that the film preparation of the present invention, produced as a film preparation which is dissolved in the oral cavity, can be suitably prepared by common or known methods.

The film preparations obtained in Example 1, Comparative Example 1, and Comparative Example 2 were evaluated for sensation when these preparations were taken. A sensory evaluation was conducted, in which the film preparations were evaluated by six panelists for sensation when these preparations were taken (bitter taste). The evaluation criteria are as follows: “a bitter taste is virtually unnoticeable” given 2 points; “a bitter taste is slightly noticeable” given 1 point; and “a bitter taste is noticeable and the taste is bad” given 0 points. Accordingly, a higher total score indicates that a bitter taste is more masked. The total scores are shown in Table 1, with the composition of each film preparation (amounts (mg) of the component per film preparation).
