Description

  The present invention relates to a solid preparation containing ibuprofen, particularly ibuprofen and tranexamic acid, in which sublimation of ibuprofen is suppressed.

Ibuprofen is effective for diseases such as rheumatoid arthritis, arthralgia and arthritis, neuralgia and neuritis, spinal and lower back pain, symptomatic inflammation, and analgesia. It is a drug that is widely used as a non-steroidal anti-inflammatory drug (NSAID) that is also effective for exacerbation and antipyretic in exacerbations.
However, since ibuprofen is a sublimable substance, it is known that when stored in a closed container such as a glass bottle, the inner wall becomes clouded over time, and various prevention methods have been studied (Patent Documents 1 to 4). reference).

On the other hand, since ibuprofen has side effects such as gastrointestinal disorders and its analgesic effect is relatively weak, formulation preparations with various drugs have been studied, and tranexamic acid has antiplasmin, antiallergic, Since it is used as a drug having an inflammatory action, many combinations of ibuprofen and tranexamic acid have been developed. For example, antipyretic analgesics containing ibuprofen and tranexamic acid (see Patent Document 6), antipyretic analgesics containing ibuprofen and tranexamic acid and caffeine (see Patent Document 7), antipyretic analgesic composition containing ascorbic acid.

As the shape of the solid preparation of the present invention, the components according to the solid preparation of the present invention may be uniformly mixed in the solid preparation, but have an inner layer containing ibuprofen and an outer layer containing polyvinyl alcohol. It is preferable that at least the outer layer contains silicic acid. In the present invention, the inner layer refers to an inner layer when the solid preparation has a multilayer structure, and the inner layer may be a core. Further, the inner layer may be a solid preparation, and in that case, the outer preparation is further formed to constitute the solid preparation of the present invention.
In the present invention, it is preferable that a solid preparation containing ibuprofen and tranexamic acid produced in advance is used as an inner layer, and an outer layer containing polyvinyl alcohol and silicic acid is further formed. Specifically, an outer layer containing polyvinyl alcohol and silicic acid is formed as a sugar coating layer or a film coating layer, or the core tablet contains ibuprofen and tranexamic acid, and the outer shell contains polyvinyl alcohol and silicic acid. Examples include making a nuclear tablet.

The solid preparation of the present invention can be produced according to a known method, for example, the method described in the Japanese Pharmacopoeia General Rules for Preparations. For example, when the dosage form is a tablet, ibuprofen, tranexamic acid and various drugs and various commonly used formulation additives are mixed or granulated based on a known method, and the resulting mixture or granulated product is desired. After the lubricant is mixed in accordance with the above, tableting is performed to produce an uncoated tablet, and then a sugar coating or film coating solution is applied based on a known method using a sugar coating solution or a film coating solution containing polyvinyl alcohol and silicic acid. Thus, the solid preparation of the present invention can be produced.
In addition, ibuprofen and tranexamic acid may be separately granulated, and these granulated products may be tableted together to produce the above-mentioned uncoated tablets. As uncoated tablets, ibuprofen is contained in the core tablet and tranexam. A dry-coated tablet containing an acid in the outer shell, or a dry-coated tablet containing tranexamic acid in the dry tablet and ibuprofen in the outer shell can also be used. From the viewpoint of avoiding an increase in ibuprofen sublimation due to tranexamic acid, it is preferable to use an uncoated tablet made of ibuprofen and tranexamic acid as separate granules or the above-mentioned dry-coated tablet as an uncoated tablet.

  Moreover, in this invention, since it is excellent on manufacture in terms of a process, cost, etc., it is preferable to set it as a film coating tablet.

The solid preparation of the present invention is sealed in a closed storage container, as will be apparent from the examples described later, and no fogging occurs on the inner wall of the storage container even when stored in a sealed state. Here, the sealed storage container is not particularly limited as long as it is a sealable storage container (packaging). For example, bottles, cans, boxes, bags (pillow packaging, stick packaging, etc.), PTP packaging, etc. For example, glass, resin, metal or the like may be used as a material, and those materials having a composite structure or a multilayer structure may be used. The container may be opaque, translucent, or transparent, but particularly in the case of a translucent or transparent container, the change in shape of the solid preparation inside the container can be visually observed. Can be grasped.

  Since the solid preparation of the present invention may contain tranexamic acid in addition to ibuprofen as a medicinal ingredient, it is used for the prevention and / or treatment of inflammation, as an antipyretic / analgesic agent or a cold medicine. The effects and effects of cold medicines include relief of cold symptoms (sore pain, fever, chills, headache, joint pain, muscle pain, etc.).

  Hereinafter, the present invention will be described more specifically with reference to examples, but the present invention is not limited thereto.

[Test Example 1]
A glass bottle (10K standard bottle) was filled with silica gel (2 g) and samples 1 and 2 below, sealed, and stored at 60 ° C. Silica gel was taken out at each time point 1 week, 2 weeks and 3 weeks after storage, and the weight was measured. The relative value of the weight of ibuprofen adsorbed on the silica gel with respect to the silica gel weight was calculated. The results are shown in Table 1.

Sample 1: 1 g of ibuprofen
Sample 2: 1 g of ibuprofen + 1 g of tranexamic acid

Weight change (%) = (B−A) × 100 / A
A: Silica gel weight at the start of storage B: Silica gel weight after storage

  From Table 1, it was found that the amount of ibuprofen sublimation was significantly higher when tranexamic acid was mixed with ibuprofen compared to ibuprofen alone.

[Example 1]
900 g of ibuprofen (manufactured by Riyone Yonezawa, trade name: Japanese Pharmacopoeia ibuprofen), 1499.4 g of tranexamic acid (manufactured by Daiichi Sankyo Propharma: trade name, Japanese Pharmacopoeia, tranexamic acid), 106.2 g of hydroxypropyl cellulose, 1897 of crystalline cellulose. 2 g and 360 g of croscarmellose sodium were added to a high-speed agitation granulator (Fukae Kogyo Co., Ltd .: FS-10 type) and mixed, and then 466 g of purified water was added and kneaded. The granulated product was put into a fluidized bed dryer (Freund Sangyo: FLO-5 type), dried, and then granulated using a granulator (Okada Seiko: ND-10 type). The sized powder 4762.8 g and magnesium stearate 97.2 g were put into a mixer (Kotobuki: PM50 type) and mixed, and then a tableting machine (made by Hata Iron Works: 8.5 mm diameter) was attached. HT-AP18SS type) was used to obtain 18000 tablets each having a mass of 270 mg. 486 g of polyvinyl alcohol (manufactured by Kuraray: trade name Poval 205S (polymerization degree 500, saponification degree 86.5-89.0 mol%)), 243 g of light anhydrous silicic acid (manufactured by Nippon Aerosil Co., Ltd .: trade name Aerosil 300), 81 g of triacetin and purified water A film coating solution consisting of 10800 g was prepared, and then coated with a tablet coating machine (manufactured by POWREC: Doria Coater 650DS) to obtain 15000 film-coated tablets having a weight of 280 mg.

[Comparative Example 1]
Instead of the light anhydrous silicic acid of Example 1, 243 g of talc (trade name: Talc MS, manufactured by Nippon Talc) was added, and tablets were obtained in the same manner as in Example 1.

[Comparative Example 2]
Instead of the polyvinyl alcohol of Example 1, 486 g of hypromellose (manufactured by Shin-Etsu Chemical Co., Ltd .: trade name TC-5R) was added, and the tablet was obtained in the same manner as in Example 1 except for that.

[Test Example 2] Evaluation of sublimation inhibition 20 tablets each obtained in Example 1 and Comparative Examples 1 and 2 were placed in a glass bottle (10K standard), sealed, and stored at 40 ° C for 3 months. After the storage period, the presence or absence of fogging of the inner wall of the glass bottle was visually determined. The results are shown in Table 2.

  As apparent from Table 2, in Comparative Examples 1 and 2, fogging was observed on the inner wall of the glass bottle. On the other hand, in Example 1 in which polyvinyl alcohol and silicic acid were blended, no fogging was observed on the inner wall of the glass bottle. Therefore, it was found that the sublimation of ibuprofen is suppressed by blending polyvinyl alcohol and silicic acid.

  ADVANTAGE OF THE INVENTION According to this invention, the solid formulation containing ibuprofen by which the sublimation of ibuprofen is suppressed, especially ibuprofen and tranexamic acid can be provided.
