Description

[Technical Field]

[0001] The present invention relates to a composition and the like. [Background technology]

[0002] Prednisolone valerate acetate, an adrenal corticosteroid, exhibits excellent anti-inflammatory activity at the affected area while being a highly safe prodrug that converts to a less active substance in the body. Such excellent efficacy and high safety characteristics are consistent with the concept of self-medication. Therefore, in Japan, prednisolone valerate acetate is widely used as an active ingredient in over-the-counter (OTC) drugs that are effective against eczema, dermatitis, rashes, insect bites, itching, heat rash, hives, and other conditions (e.g., Non-Patent Documents 1 and 2). [Prior art documents] [Non-patent literature]

[0003] [Non-Patent Document 1] Package insert: "Eczema and Dermatitis Treatment Drug Livmex Kowa Cream," Kowa Company, Ltd., October 2011 [Non-patent document 2] Package insert: "Eczema and Dermatitis Treatment Drug Livmex Kowa Ointment," Kowa Company, Ltd., October 2012 Summary of the Invention [Problem to be solved by the invention]

[0004] All OTC medications containing prednisolone valerate acetate that have been sold to date are liquid or semi-solid compositions (e.g., ointments and creams) containing 1.5 mg of prednisolone valerate acetate per mL of composition (i.e., 0.15 w / v% of the total volume of the composition). However, since the anti-inflammatory effect is basically dose-dependent, it is believed that if the content of prednisolone valerate acetate is more than 0.15 w / v%, it will be possible to produce a pharmaceutical product with stronger anti-inflammatory effect and superior efficacy.

[0005] The present inventors therefore investigated the storage stability of liquid or semi-solid compositions containing more than 0.15 w / v% prednisolone valerate acetate in order to develop such compositions. They found that liquid or semi-solid compositions containing 0.3 w / v% prednisolone valerate acetate, based on the total volume of the composition, developed crystal precipitation problems after storage at -20°C for one week. Liquid or semi-solid compositions containing 0.15 w / v% prednisolone valerate acetate, such as conventional over-the-counter (OTC) pharmaceuticals, did not develop crystal precipitation problems under the same storage conditions. Therefore, it was determined that crystal precipitation during storage at such low temperatures occurs when the composition contains more than 0.15 w / v% prednisolone valerate acetate, based on the total volume of the composition. Therefore, an object of the present invention is to provide a liquid or semi-solid composition which contains more than 0.15 w / v % of prednisolone valerate acetate based on the total volume of the composition and which is inhibited from forming crystals when stored at low temperatures. [Means for solving the problem]

[0006] Therefore, the present inventors have conducted further intensive studies to solve the above-mentioned problems, and have found that a liquid or semi-solid composition containing more than 0.15 w / v % of prednisolone valerate acetate (hereinafter, in this specification, this may be simply referred to as "component (A)") relative to the total volume of the composition, further contains any one of the following components 1 to 7 (hereinafter, in this specification, components 1 to 6 will be referred to as "component (B-1)," "component (B-2)," "component (B-3)," "component (B-4)," "component (B-5)," "component (B-6)," and "component (B-7)," respectively, and "one or more selected from the group consisting of components (B-1) to (B-7)" will be referred to as "component (B)"):

[0007] 1. Local anesthetic ingredients, such as lidocaine and lidocaine hydrochloride 2: Crotamitons, represented by crotamiton 3. Antihistamine ingredients, such as diphenhydramine and diphenhydramine hydrochloride 4: Salicylic acids, such as glycol salicylate 5: Terpenes, such as l-menthol, dl-camphor, and isopropylmethylphenol 6: Panthenols, typified by panthenol 7: Hydroxycarboxylic acids, such as sodium citrate

[0008] The present inventors have found that by incorporating component (B), crystal precipitation during storage at low temperatures is relatively suppressed compared to when component (B) is not incorporated, and have completed the present invention.

[0009] That is, the present disclosure provides a composition comprising the following components (A) and (B): (A) prednisolone valerate acetate in an amount greater than 0.15 w / v% based on the total volume of the composition; (B) one or more selected from the group consisting of the following components (B-1) to (B-7): (B-1) Local anesthetic ingredient (B-2) Crotamiton (B-3) Antihistamine ingredients (B-4) Salicylic acids (B-5) Terpenes (B-6) Panthenols (B-7) Hydroxycarboxylic acids The present invention provides a liquid or semi-solid composition comprising: [Effects of the Invention]

[Example]

[0055] The present invention will be described in detail below with reference to examples, but the present invention is not limited to these examples in any way.

[0056] [Test Example 1] Preservation test Part 1 Various liquid compositions containing the components and amounts (g) shown in Table 1 below per 100 mL were prepared by a conventional method and placed in glass bottles (2K standard bottles). The resulting compositions were stored for one week at −20° C. After storage, the presence or absence of crystal precipitation in the composition was visually confirmed, and the composition was evaluated as ◯ when no crystal precipitation was observed, and × when crystal precipitation was observed. The results are shown in Table 1 together with the content (w / v%) of prednisolone valerate acetate in each composition.

[0057] [Table 1]

[0058] The results shown in Table 1 indicate that the composition of Reference Example 1, which contained 0.15 w / v% prednisolone valerate acetate based on the total mass of the composition, showed no crystal precipitation even after storage at −20° C. for 1 week, whereas the composition of Comparative Example 1, which contained 0.3 w / v%, showed crystal precipitation. This indicates that such crystal precipitation is a problem that occurs when the content of prednisolone valerate acetate exceeds 0.15 w / v%. However, it was revealed that the composition of Example 1, which further contains lidocaine in addition to 0.3 w / v% prednisolone valerate acetate, and the composition of Example 2, which also contains lidocaine hydrochloride, did not undergo crystal precipitation even after storage at -20°C for one week.

[0059] The above test results demonstrate that by further adding a local anesthetic component, such as lidocaine or lidocaine hydrochloride, to a liquid or semi-solid composition containing more than 0.15 w / v% prednisolone valerate acetate, crystal precipitation is relatively suppressed compared to when such a component is not added.

[0060] [Test Example 2] Preservation test Part 2 Various liquid compositions containing the ingredients and amounts (g) shown in Table 2 below per 100 mL were prepared by a conventional method, and tests were carried out in the same manner as in Test Example 1. The results are shown in Table 2.

[0061] [Table 2]

[0062] The test results shown in Table 2 reveal that the composition of Example 3, which contains crotamiton in addition to 0.3 w / v% prednisolone valerate acetate, also does not exhibit crystal precipitation even after storage at -20°C for one week, similar to the compositions of Examples 1 and 2.

[0063] The above test results demonstrate that the inclusion of a crotamiton congener, such as crotamiton, in a liquid or semi-solid composition containing more than 0.15 w / v% prednisolone valerate acetate can relatively suppress crystal precipitation compared to a composition that does not contain such a component.

[0064] [Test Example 3] Preservation test No. 3 Various liquid compositions containing the ingredients and amounts (g) per 100 mL shown in Table 3 below were prepared by a conventional method, and tests were carried out in the same manner as in Test Example 1. The results are shown in Table 3.

[0065] [Table 3]

[0066] The test results shown in Table 3 reveal that, similar to the compositions of Examples 1 and 2, the composition of Example 4, which contains diphenhydramine in addition to 0.3 w / v % prednisolone valerate acetate, and the composition of Example 5, which contains diphenhydramine hydrochloride, do not produce crystal precipitation even after storage at -20°C for one week.

[0067] The above test results demonstrate that by further adding an antihistamine component, such as diphenhydramine or diphenhydramine hydrochloride, to a liquid or semi-solid composition containing more than 0.15 w / v % prednisolone valerate acetate, crystal precipitation is relatively suppressed compared to when such an component is not added.

[0068] [Test Example 4] Preservation test No. 4 Various liquid compositions containing the ingredients and amounts (g) shown in Table 4 below per 100 mL were prepared by a conventional method, and tests were carried out in the same manner as in Test Example 1. The results are shown in Table 4.

[0069] [Table 4]

[0070] The test results shown in Table 4 reveal that the composition of Example 6, which contains glycol salicylate in addition to 0.3 w / v% prednisolone valerate acetate, also does not produce crystal precipitation after storage at -20°C for 1 week, similar to the compositions of Examples 1 and 2.

[0071] The above test results demonstrate that by further adding a salicylic acid, such as glycol salicylate, to a liquid or semi-solid composition containing more than 0.15 w / v % of prednisolone valerate acetate, crystal precipitation is relatively suppressed compared to when such a component is not added.

[0072] [Test Example 5] Preservation test No. 5 Various liquid compositions containing the ingredients and amounts (g) shown in Table 5 below per 100 mL were prepared by a conventional method, and tests were carried out in the same manner as in Test Example 1. The results are shown in Table 5.

[0073] [Table 5]

[0074] The test results shown in Table 5 reveal that, similar to the compositions of Examples 1 and 2, the composition of Example 7 containing 1-menthol in addition to 0.3 w / v% prednisolone valerate acetate, the composition of Example 8 containing dl-camphor, and the composition of Example 9 containing isopropylmethylphenol also do not cause crystal precipitation after storage at -20°C for one week.

[0075] From the above test results, it was revealed that by further adding terpenes, such as l-menthol, dl-camphor, or isopropylmethylphenol, to a liquid or semi-solid composition containing more than 0.15 w / v % of prednisolone valerate acetate, crystal precipitation is relatively suppressed compared to when these components are not added.

[0076] [Test Example 6] Storage test No. 6 Various liquid compositions containing the ingredients and amounts (g) per 100 mL shown in Table 6 below were prepared by a conventional method, and tests were carried out in the same manner as in Test Example 1. The results are shown in Table 6.

[0077] [Table 6]

[0078] The test results shown in Table 6 reveal that the composition of Example 10, which contains panthenol in addition to 0.3 w / v% prednisolone valerate acetate, also does not exhibit crystal precipitation even after storage at -20°C for one week, similar to the compositions of Examples 1 and 2.

[0079] The above test results demonstrate that by further adding a panthenol, such as panthenol, to a liquid or semi-solid composition containing more than 0.15 w / v % prednisolone valerate acetate, crystal precipitation is relatively suppressed compared to when such a component is not added.

[0080] [Test Example 7] Preservation test No. 7 Various liquid compositions containing the ingredients and amounts (g) shown in Table 7 below per 100 mL were prepared by a conventional method, and tests were carried out in the same manner as in Test Example 1. The results are shown in Table 7.

[0081] [Table 7]

[0082] The test results shown in Table 7 reveal that the composition of Example 11, which contains sodium citrate in addition to 0.3 w / v% prednisolone valerate acetate, also does not produce crystal precipitation even after storage at -20°C for 1 week, similar to the compositions of Examples 1 and 2.

[0083] The above test results demonstrate that by further adding an oxycarboxylic acid, such as sodium citrate, to a liquid or semi-solid composition containing more than 0.15 w / v % prednisolone valerate acetate, crystal precipitation is relatively suppressed compared to when such an ingredient is not added.
