[0008] However, the storage stability of the active ingredient is largely dependent on its physical and chemical properties.

Problems often only become apparent after the product has been manufactured. Furthermore, with respect to pemafibrates or their salts or solvates, as described above... It has only been reported that it exhibits pharmacological effects, and it is not yet considered a pharmaceutical composition.

Furthermore, pharmaceutical compositions typically contain, in addition to the active ingredient, Various pharmaceutical additives are included. Against this backdrop, the present inventors have discovered a pemafibrate or its salt or its solvent. In order to develop a pharmaceutical composition containing a waxy substance, the storage stability when using various formulation additives was examined. However, although pemafibrate itself is extremely stable, even when (meth)acrylic acid-based polymers typified by aminoalkyl methacrylate copolymer E coexist, a formulation change occurs, and it has been found that a problem of storage stability occurs where the mixture melts over time. Therefore, an object of the present invention is to provide a technique for suppressing a formulation change between pemafibrate or a salt thereof or a solvate thereof and (meth)acrylic acid-based polymers.
Means for Solving the Problems

[0041] As for the airtight packaging, commercially available packaging can be used as is, or commercially available packaging materials can be added. It may be modified for use. Examples of commercially available bottle packaging include the Z-series (Hanshin Examples include those manufactured by Kasei Kogyo Co., Ltd., and the A-series (manufactured by Isoya Glass Industry Co., Ltd.). Also, SP packaging, P For TP packaging, pillow packaging, and stick packaging, Sumilight VSS and Sumilight are used as packaging materials. Light VSL, Sumilight NS, Sumilight FCL (all manufactured by Sumitomo Bakelite Co., Ltd.), T AS series (manufactured by Taisei Chemical Co., Ltd.), PTP vinyl foil, PTP super foil (all of the above, Mitsubishi Plastics Ltd., Nippaku Aluminum Foil (Nippon Foil Co., Ltd.), Plain Silver Aluminum Foil (Yamato Chemical Industry Co., Ltd.) Examples include (manufactured by...).
[0042] The method of enclosing the pharmaceutical composition in an airtight package is not particularly limited, and the contents of the package This can be achieved by placing the pharmaceutical composition inside the packaging by appropriate means such as adding the pharmaceutical composition. In this case, a desiccant (for example, cylindrical tablets) is placed inside the packaging along with the pharmaceutical composition. A method for introducing molded or sheet-like materials may also be used.
[0043] The diseases to which the pharmaceutical product of this invention may be applied are not limited in any way, but may include those currently known or to be discovered in the future. Furthermore, it is widely used for the prevention or treatment of diseases in which pemafibrate administration is considered effective. It is possible. For example, pemafibrates or their salts or solvates are excellent PPARα It possesses gonist activity, leading to a decrease in plasma triglyceride concentration and an increase in HDL cholesterol, etc. It has the effect of [details omitted].

[Examples]
[0048] The present invention will be described in more detail below with reference to examples, but the present invention is not limited in any way by these examples. It is not something that should be done.
[0049] [Test Example 1] Stability Test After preparing samples 1-1 to 1-4 shown below, set them at 40°C and 75% relative humidity (RH) The samples were stored for one month under the following conditions, and the changes in the state of the samples immediately after the start of storage and after one month were observed. We evaluated whether or not there was a change in the formulation and confirmed whether or not there was a change in the composition. The results are shown in Table 1.
[0050] [Sample 1-1] Place the pemafibrate in an open glass container and use it as is for sample 1-1. Ta. [Sample 1-2] Aminoalkyl methacrylate copolymer E (Eudragit EPO: Evonik Rohm GmbH) The sample was placed in an open glass container and designated as Sample 1-2. [Sample 1-3] Per 1 part by mass of pemafibrate, aminoalkyl methacrylate copolymer E (Oil A mixture is obtained by mixing Dragit EPO (Evonik Rohm GmbH) at a ratio of 1 part by mass, and this is then used. The samples were placed in open glass containers and designated as Samples 1-3. [Sample 1-4] Per 1 part by mass of pemafibrate, aminoalkyl methacrylate copolymer E (Oil A mixture was obtained by mixing Dragit EPO (Evonik Rohm GmbH) at a ratio of 1 part by mass. Place 0.25g of the mixture into a glass bottle (2K standard bottle: Isoya Glass Industry) and close the lid. These were designated as Samples 1-4.
[0051] [Table 1]
[0052] From the test results shown in Table 1, in sample 1-1, which used only pemafibrate, for 1 month... Even after storage, the white powder state is maintained, just as it was immediately after storage began. In samples 1-2 containing only rate copolymer E, a slight discoloration from white to a faint yellow was observed. While it is only compressed and remains in a state that is almost unchanged as a powder, pemafibros In samples 1-3, which were a mixture of t and aminoalkyl methacrylate copolymer E, A change in composition occurred, causing the mixture to melt and transform significantly from a powder to a candy-like consistency. On the other hand, pemafibrate and aminoalkyl methacrylate copolymer E are mixed, In samples 1-4, which were contained in airtight packaging, the results after one month of storage were the same as immediately after storage began. Similarly, it was found that the white powdery state was maintained.
[0053] Based on the above test results, pemafibrate and aminoalkyl methacrylate copolymer The compound changes between (meth)acrylic acid polymers, such as E, are contained in airtight packaging. It became clear that this would suppress the effect.
