The solid composition is in particular a solid pharmaceutical composition.

[0015] Each component contained in the solid composition according to this embodiment may be contained in the form of a pharmacologically acceptable salt, or may be contained as a complex with another component. That is, the solid composition according to this embodiment may contain salts of not only components (B) to (C), but also component (A) and other components. "Pharmacologically acceptable salts" include, for example, salts with pharmaceutically acceptable bases or acids. Non-limiting specific examples of pharmacologically acceptable salts include addition salts of inorganic acids (hydrochloric acid, hydrobromic acid, hydroiodic acid, sulfuric acid, phosphoric acid, etc.), addition salts of organic acids (p-toluenesulfonic acid, methanesulfonic acid, oxalic acid, p-bromophenylsulfonic acid, carboxylic acids, succinic acid, citric acid, benzoic acid, acetic acid, etc.), addition salts of inorganic bases (ammonium hydroxide or alkali or alkaline earth metal hydroxides, carbonates, bicarbonates, etc.), and addition salts of amino acids. The pharmacologically acceptable salt may be a hydrated salt or an anhydrous salt.

[0016] In this embodiment, in addition to at least one selected from the group consisting of ibuprofen, tipepidine and its salts, the solid composition contains the above-mentioned component (C), thereby suppressing changes in properties of the solid composition, particularly changes in properties over time.

[0017] As used herein, "change in properties" refers to a change in properties and / or state, including at least aggregation, solidification, discoloration, moisture absorption, separation, and liquefaction. Therefore, the solid composition of this embodiment may be inhibited from undergoing any of aggregation, discoloration, moisture absorption, separation, and liquefaction over time. Furthermore, "inhibited change in properties" means that the property change is unlikely to occur, and may be inhibited, for example, compared to a solid composition that does not contain the above-mentioned component (C).

[0018] The solid composition of this embodiment may be prevented from changing in properties under high temperature conditions. The high temperature conditions may be, for example, 30 to 100°C or 40 to 90°C.

[0019] The period during which the change in properties of the solid composition of this embodiment is suppressed is not particularly limited, and may be, for example, 12 hours or more, 18 hours or more, 24 hours or more, one week or more, or two weeks or more.

[0022] Here, "loratadine" means a compound having the chemical formula C 22 H 23 The compound is represented by ClN2O2 and has the CAS registration number 79794-75-5.

[0023] Furthermore, the solid composition of this embodiment excludes the solid compositions disclosed in Japanese Patent Application Laid-Open No. 2022-008041 and Japanese Patent Application Laid-Open No. 2020-158487. The solid composition disclosed in Japanese Patent Application Laid-Open No. 2022-008041 is a pharmaceutical composition containing ibuprofen and levocetirizine or a salt thereof, in which the decrease in the content of levocetirizine or a salt thereof over time is suppressed, and the solid composition disclosed in Japanese Patent Application Laid-Open No. 2020-158487 is a solid composition containing ibuprofen and loratadine, in which the decrease in the content of loratadine over time is suppressed. However, the solid composition of this embodiment is a solid composition containing ibuprofen in which changes in properties that may occur when at least one selected from the group consisting of tipepidine and salts thereof is added to ibuprofen are suppressed.

[0024] (A) Ibuprofen As used herein, "ibuprofen" refers to ibuprofen having CAS Registry Number 15687-27-1 and C 13 H 18 Ibuprofen is a compound represented by the chemical formula O2 (molecular weight: 206.29 g / mol). Ibuprofen is used as an active ingredient in anti-inflammatory, analgesic, and antipyretic drugs. There are no particular restrictions on the salts of ibuprofen, as long as they are pharmacologically acceptable.

[0025] The amount of ibuprofen to be added is adjusted as appropriate depending on the intended use of ibuprofen in the solid composition, the symptoms, age, weight, sex, and the like of the recipient. For example, when ibuprofen is added as a nonsteroidal anti-inflammatory drug, the daily amount of ibuprofen to be administered to an adult can be adjusted to, for example, 30 mg to 2000 mg, preferably 100 mg to 1000 mg, and more preferably 200 mg to 600 mg. In this embodiment, "adult" refers to both men and women aged 15 years or older. However, the solid composition according to this embodiment is not limited to that intended for adults, and may also be that intended for children under 15 years of age. When administered to children, the amount can be reduced to, for example, 1 / 2 or 2 / 3 of the amount administered daily by adults depending on the age group. The same applies to ingredients other than ibuprofen.

[0026] The above dosage is an example, and the content of ibuprofen per solid composition administered per day is, for example, about 1% by mass to about 70% by mass, preferably about 5% by mass to about 50% by mass, and more preferably about 10% by mass to about 30% by mass.

[0027] In one embodiment, the content of ibuprofen in the composition to be administered daily is 1 to 70% by mass, preferably 5 to 50% by mass, and more preferably 10 to 30% by mass.

[0028] The weight and dosage of the solid composition described above are the daily dosage (daily dose), but the same amount may be administered to the subject once or multiple times a day, for example, twice or three times, preferably three times. The same applies to ingredients other than ibuprofen. Furthermore, since each dosage is the total amount, the content of each ingredient contained in the solid composition may vary depending on the single dose, the dosage form of the solid composition, etc.

[0029] In a specific embodiment, the solid composition is a tablet, and the dosage is the amount of the ingredient contained in 3, 6, or 9 tablets, preferably the amount of the ingredient contained in 9 tablets.

[0033] In one embodiment, the content of tranexamic acid and uncrystallized ibuprofen in the solid composition is, for example, 10% by weight or less, 8% by weight or less, 5% by weight or less, 3% by weight or less, 1% by weight or less, or 0.1% by weight or less, based on the total amount of ibuprofen.

[0034] (B) at least one selected from the group consisting of tipepidine and salts thereof As used herein, "tipepidine" refers to the compound having the CAS Registry Number 5169-78-8 and C 15 H 17 It is a compound represented by the chemical formula NS2 (molecular weight: 275.43 g / mol). The salt of tipepidine is not particularly limited as long as it is pharmacologically acceptable, and examples thereof include tipepidine hibenzate and tipepidine citrate. Note that the amount and content of at least one selected from the group consisting of tipepidine and its salts described below refer to the amount and content of each of tipepidine and tipepidine salt, but it is preferable that the total amount and content of tipepidine and tipepidine salt fall within the ranges of the amount and content described below.

[0035] The amount of component (B) at least one selected from the group consisting of tipepidine and its salts is adjusted appropriately depending on the use of the solid composition, the required level of antitussive and expectorant effect, the required level of stability, and the symptoms, age, weight, sex, etc. of the subject to be administered.

[0036] The amount of at least one compound selected from the group consisting of tipepidine and its salts may vary depending on the amount of ibuprofen, etc. For example, the mass ratio ((A):(B)) of the total amount of component (A) to component (B) in the solid composition according to this embodiment is preferably 1:1 to 16:1, more preferably 1:1 to 14:1, and even more preferably 1:1 to 10:1, in the solid composition administered daily. By including at least one compound selected from the group consisting of tipepidine and its salts in the above range relative to ibuprofen, changes in the properties of the solid composition tend to be more effectively suppressed.

[0037] The amount of at least one compound selected from the group consisting of tipepidine and salts thereof can be adjusted, for example, in the range of 5 mg to 140 mg, more preferably 16 mg to 100 mg per day.

[0038] (C) at least one selected from the group consisting of tranexamic acid and salts thereof As used herein, "tranexamic acid" refers to the compound having the CAS Registry Number 1197-18-8 and C8H 15 It is a compound represented by the chemical formula NO2 (molecular weight: 157.21 g / mol). Tranexamic acid is used as an active ingredient in anti-inflammatory drugs and the like. There are no particular limitations on the salt of tranexamic acid, as long as it is pharmacologically acceptable. Note that the amount and content of at least one selected from the group consisting of tranexamic acid and its salts described below refer to the amount and content of tranexamic acid and the salt of tranexamic acid, respectively, but it is preferable that the total amount and content of tranexamic acid and the salt of tranexamic acid fall within the ranges of the amount and content described below.

[0039] The amount of at least one selected from the group consisting of tranexamic acid and its salts is adjusted appropriately depending on the application of the at least one selected from the group consisting of tranexamic acid and its salts in the composition. When at least one selected from the group consisting of tranexamic acid and its salts is added for the purpose of preventing changes in the properties of ibuprofen or improving other properties, the amount of at least one selected from the group consisting of tranexamic acid and its salts varies depending on the amount of ibuprofen, etc., but for example, the amount per day is in the range of 10 mg to 3000 mg, preferably 100 mg to 1500 mg, and more preferably 400 mg to 750 mg.

[0040] The content of at least one selected from the group consisting of tranexamic acid and salts thereof in the composition administered daily is 1% by mass to 70% by mass, preferably 5% by mass to 50% by mass, and more preferably 10% by mass to 30% by mass.

[0041] The amount of at least one selected from the group consisting of tranexamic acid and salts thereof contained in the composition administered daily is, for example, 0.5 to 3.5 parts by mass, preferably 0.6 to 3.0 parts by mass, and more preferably 0.7 to 2.2 parts by mass per part by mass of ibuprofen.

[0042] The description of the amount of at least one selected from the group consisting of tranexamic acid and salts thereof described in this specification may refer to the total amount of at least one selected from the group consisting of crystallized tranexamic acid and non-crystallized tranexamic acid and salts thereof.

[0089] (Dosage form) The solid composition of this embodiment can be in the dosage form described in the General Provisions for Preparations of the Japanese Pharmacopoeia, 18th Edition, etc., such as preparations for oral administration (tablets (including orally disintegrating tablets, chewable tablets, effervescent tablets, dispersible tablets, dissolving tablets, etc.), capsules, granules, powders, etc.), preparations for oral application (including oral tablets, troches, sublingual tablets, buccal tablets, adhesive tablets, gums, etc.). The solid composition of this embodiment is preferably an oral solid composition.

[0090] The dosage form of the solid composition of this embodiment may be, for example, a tablet, a capsule, a pill, a granule, or a fine granule. These solid compositions may be coated with sugar coating, film coating, or the like by a known method, as needed. The dosage form of the solid composition is preferably a tablet. Specific examples of tablets include plain tablets, film-coated tablets, and sugar-coated tablets.

[0091] The solid composition of this embodiment may be temporarily packaged in a bottle, PTP, pouch, stick, or SP package and then stored airtight. These may then be pillow-packaged, or stored in a box or the like. The material used for the pillow packaging is not particularly limited, and examples include resin films such as polypropylene film, polyethylene terephthalate film, and polyethylene film, as well as these resin films with aluminum foil attached. If moisture absorption is a concern, a desiccant or the like may be stored simultaneously in the bottle packaging or pillow packaging.

[0092] The solid composition of this embodiment may be contained in a packaging container to form a package. The solid composition of this embodiment may be contained in, for example, an airtight package. By forming the solid composition into a package, for example, convenience during use of the solid composition can be improved. Specifically, the package in this embodiment is a pharmaceutical product.

[0093] As for the packaging form of the solid preparation, the solid composition may be temporarily packaged and stored airtight in a bottle, PTP (Press-Through Package), pouch, stick, or SP (Strip Package) or the like. These may also be pillow-packaged, or may be stored in a box or the like. Furthermore, from the viewpoint of reducing moisture absorption of the solid composition, a desiccant or the like may be stored in the packaging container, such as the bottle or pillow package, at the same time.

[0094] Materials used for SP packaging, PTP packaging, stick packaging, pillow packaging, etc. include resin films such as polypropylene film, polyethylene terephthalate film, and polyethylene film, as well as these resin films with aluminum foil attached. Either single-layer films or multi-layer films (e.g., laminate films) may be used.

[0095] Furthermore, it is preferable that the material constituting the packaging container contains a material that is resistant to the effects of moisture. Examples of such packaging include packaging made of at least one of a moisture-proof material and a gas barrier material.

[0096] An example of a moisture-proof material is a combination of PTP (polypropylene) and polyethylene aluminum pillow packaging. When the solid composition is a tablet, PTP packaging (Al-Al packaging) with aluminum on both sides may be used as the moisture-proof material, taking into consideration the prevention of an increase in the moisture content of the tablet, the storage stability of the tablet, and the stability of the tablet after opening.

[0097] Any known gas barrier material may be used, for example, a laminate film having a functional barrier layer, which may also serve as the moisture-proof material or may be used in combination with the moisture-proof material.

[0098] Furthermore, the packaging container may be environmentally friendly. For example, environmentally friendly materials such as recycled plastics, biomass plastics, and biodegradable plastics may be used for part or all of the packaging material.

[0099] (Manufacturing method) In a second aspect, there is provided a method for producing a solid composition, comprising the steps of contacting (A) ibuprofen, (B) at least one selected from the group consisting of tipepidine and salts thereof, and (C) at least one selected from the group consisting of tranexamic acid and salts thereof.

[0100] The solid composition can be produced using known techniques. The components are added at any step and finally contacted with each other. A solvent or binder may be added to the contacted mixture and kneaded, and the resulting kneaded product may be used as a solid composition. Crystals of ibuprofen and tranexamic acid can be produced by the method described in JP 2022-70674 A (cited above). After forming crystals of ibuprofen and tranexamic acid, the crystals may be contacted with or kneaded with (B) at least one selected from the group consisting of tipepidine and salts thereof.

[0101] The resulting kneaded mixture can be further subjected to a drying process and a granulation process to produce granules (granulated material). In this case, granules (granulated material) containing each component may be prepared separately. Granulation may be performed by either a wet method or a dry method.

[0102] The obtained granules (granulated product) can be used as they are or can be mixed with additives and compressed into tablets to produce plain tablets, which can then be further film-coated.

[0103] (Property change inhibitor) In a third aspect, there is provided an agent for inhibiting property changes in a solid composition comprising (I) ibuprofen and (II) at least one selected from the group consisting of tipepidine and salts thereof, which comprises at least one selected from the group consisting of tranexamic acid and salts thereof.

[0104] The at least one member selected from the group consisting of tranexamic acid and salts thereof is as described in component (C) of the solid composition of this embodiment, and the above components (I) and (II) are as described in components (A) and (B) of the solid composition of this embodiment.

[0105] The property change inhibitor is preferably used in an amount such that the amount of at least one selected from the group consisting of tranexamic acid and its salts relative to component (I) or (II) falls within the range described as the preferred content of component (C) in the solid composition of this embodiment. Furthermore, tranexamic acid is preferably crystallized with ibuprofen and then added to the solid composition (in the crystallized state).

[0106] In order to explain the present invention in more detail, examples are described below, but the present invention is not limited to these examples. [Example]

[0107] 1.Raw materials In this example, the following raw materials were used: [Table 1]

[0108] 2. Preparation of Solid Composition (Comparative Example 1) 50 g of tipepidine hibenzate and 50 g of ibuprofen (manufactured by SI Group) were weighed out and mixed in a bag 100 times. After sieving through a 42-mesh sieve, the mixture was further mixed in a bag 100 times to obtain a physically mixed powder. 2 g of the obtained physically mixed powder was weighed into a 1K standard bottle, sealed, and then adjusted to a uniform thickness to obtain a sample for Comparative Example 1.

[0109] (Example 1, Comparative Examples 2 to 4) 2.5 g of tranexamic acid (Kyowa Pharma Chemical), tartaric acid, sodium bicarbonate, or noscapine was added to 5 g of the physically mixed powder obtained in Comparative Example 1, and the mixture was mixed in a bag 100 times. 2 g of the resulting mixture was weighed into a 1K standard bottle, sealed, and then adjusted to a uniform thickness to prepare the samples of Example 1 and Comparative Examples 2 to 4.

[0110] Example 2 10 g of tipepidine hibenzate, 10 g of ibuprofen (manufactured by SI Group), and 7.6 g of tranexamic acid (manufactured by Kyowa Pharma Chemical) were weighed out and mixed in a bag 100 times. After sieving through a 42-mesh sieve, the mixture was further mixed in a bag 100 times to obtain a physically mixed powder. 2 g of the obtained physically mixed powder was weighed into a 1K standard bottle, sealed, and adjusted to a uniform thickness to obtain a sample of Example 2.

[0111] Example 3 240.0 g of ibuprofen (manufactured by Yonezawa Hamari) and 182.9 g of tranexamic acid (manufactured by AMI) were charged into a stirring mixer granulator (Vertical Granulator VG-5 (manufactured by Powrex)) and mixed to obtain a mixed powder. 69 g of a mixture of ethanol (purity 99.5%) (manufactured by Kanto Chemical) and purified water (mass ratio 8:2) was added to this mixed powder, and the mixture was kneaded and granulated to obtain a kneaded product. The kneaded product was wet-milled using a Power Mill (manufactured by Dalton) at low speed and 32 mesh. The mixture was then stored in a constant temperature bath at 70°C for 89 hours to obtain crystals consisting of ibuprofen and tranexamic acid.

[0112] 6 mg of the obtained crystals were placed in an aluminum pan and measured using a differential scanning calorimeter DSC3+ (Mettler-Toledo) at a rate of 60°C per minute over the range of 25 to 350°C. The results are shown in Figure 1. As shown in Figure 1, the peak due to ibuprofen around 75°C disappears, and a peak due to crystals consisting of ibuprofen and tranexamic acid appears around 180°C, confirming that crystals with a molar ratio of ibuprofen to tranexamic acid of 1:1 were obtained.

[0113] Next, 17.6 g of the obtained crystals and 10 g of tipepidine hibenzate were weighed and mixed in a bag 100 times. After sieving through a 42-mesh sieve, the mixture was further mixed in a bag 100 times to obtain a physically mixed powder. 2 g of the obtained physically mixed powder was weighed into a 1K standard bottle, sealed, and adjusted to a uniform thickness to obtain a sample of Example 3.

[0114] The blending ratio (mass ratio) of each sample is shown in the table below. In the table below, "IB-TXA crystal" refers to a crystal composed of ibuprofen and tranexamic acid. [Table 2]

[0115] 3. Evaluation of changes in the properties of solid compositions Each sample of Example 1 and Comparative Examples 1 to 4 was stored at 80°C for 24 hours and evaluated for changes in properties. The changes in properties were observed for changes in state such as aggregation, solidification, moisture absorption, separation, and liquefaction. The state changes were visually confirmed before and after storage to see whether aggregation, solidification, moisture absorption, separation, or liquefaction of the powder had occurred.

[0116] The change in condition was then evaluated according to the following criteria. Condition change A: No change, B: Slight change, C: Change, D: Significant change

[0117] The results of the state change compared to when high-temperature storage began are shown in the table below. Significant state changes were observed in Comparative Examples 1 to 4. Specifically, Comparative Examples 1, 2, and 4 were partially liquefied and separated into two layers. Comparative Example 3 experienced aggregation and solidification. On the other hand, state changes were suppressed in Example 1. Specifically, although aggregation and solidification occurred, the change was suppressed compared to Comparative Example 3. From the above, it was demonstrated that the tranexamic acid added in Example 1 can suppress changes in the properties of ibuprofen and tipepidine hibenzate under high-temperature conditions.

[0118] [Table 3]

[0119] Next, each sample of Examples 2 and 3 and Comparative Example 1 was stored at 80°C for two weeks to evaluate long-term changes in properties. The changes in properties were observed in terms of color change and state changes such as aggregation, solidification, moisture absorption, separation, and liquefaction. The changes in color were observed by visual inspection before and after storage to determine whether a change in color was observed. The changes in state were observed by visual inspection before and after storage to determine whether aggregation, solidification, moisture absorption, separation, and liquefaction of the powder occurred.

[0120] Next, the color change and state change were evaluated according to the following criteria. Color change A: No discoloration, B: Slight discoloration, C: Discoloration, D: Significant discoloration Condition change A: No change, B: Slight change, C: Change, D: Significant change

[0121] The results of the color change and state change compared to when high-temperature storage began are shown in the table below. In Comparative Example 1, significant changes in both color and state were observed. Specifically, the product turned dark brown, partially liquefied, and separated into two layers. In contrast, in Example 2, the state change was suppressed. Specifically, the product turned brown and aggregated, but the aggregated solidification was partial. In Example 3, both the color change and state change were suppressed. Specifically, the product maintained its white powder state even after two weeks. These findings demonstrate that tranexamic acid can suppress changes in the properties of ibuprofen and tipepidine hibenzate under high-temperature conditions, and that this effect is particularly pronounced when crystals consisting of ibuprofen and tranexamic acid are formed.

[0122] [Table 4]

[0123] Although the preferred embodiments and examples of the present invention have been described above, the present invention is not limited to these. Addition, omission, substitution, and other modifications of the configuration are possible within the scope of the present invention.
