Abstract
Description
Technical Field
[0001] The present invention relates to a liquid agent containing an antifungal agent and used without being washed away, such as a pharmaceutical, quasi-drug, or cosmetic, and more particularly to a liquid agent containing an azole antifungal agent and used without being washed away.
Background Art
[0002] As liquid agents used without being washed away, such as pharmaceuticals, quasi-drugs, or cosmetics, so-called leave-on type liquid agents, for example, dry shampoos, antiperspirants, deodorants, bactericides, disinfectants, etc. are known. On the other hand, as a composition containing an azole antifungal agent and a surfactant, a cleaning composition for pharmaceuticals, quasi-drugs, or cosmetics containing (A) miconazole and / or its salt, (B) a specific antioxidant, and (C) a surfactant (Patent Document 1), and an external composition containing (A) an azole antifungal agent, (B) an anti-inflammatory agent, and (C) a coconut oil fatty acid acyl amino acid-based anionic surfactant (Patent Document 2) have been proposed.
[0003] The invention related to the cleaning composition disclosed in Patent Document 1 aims to suppress the decrease in the content of miconazole over time (able to be maintained at a predetermined amount containing miconazole) regardless of coexisting components such as surfactants, and in order to achieve such an object, it is proposed to add (B) a specific antioxidant. Further, Patent Document 1 is a cleaning composition with a large amount of (C) surfactant blended, and a composition of the non-rinse type containing a small amount of surfactant is not disclosed. In addition, the invention related to the external composition disclosed in Patent Document 2 aims to suppress the increase in formulation viscosity over time and the occurrence of white residue after drying by using a combination of an azole antifungal agent and a coconut oil fatty acid acyl amino acid-based anionic surfactant, and also to suppress the decrease in the residual rate of the azole antifungal agent by using a combination of the azole antifungal agent and an anti-inflammatory agent. To achieve such an object, a combination of (A) an azole antifungal agent, (B) an anti-inflammatory agent, and (C) a coconut oil fatty acid acyl amino acid-based anionic surfactant is proposed. Therefore, Patent Documents 1 and 2 do not propose nor suggest the problem that the azole antifungal agent precipitates during storage when the content of the surfactant is small in a composition containing an azole antifungal agent and a surfactant, nor do they propose or suggest means for suppressing the precipitation of the azole antifungal agent.

Summary of the Invention
Problems to be Solved by the Invention
[0005] For liquids that are used as pharmaceuticals, quasi-drugs, cosmetics, etc. and are used without being washed off, low irritation is required due to their usage mode. Therefore, it is desirable that the amount of irritating substances (e.g., surfactants, alcohols, etc.) in the liquid is as small as possible.

[0028] Preferable specific examples of the nonionic surfactant that can be used in the present invention are those described in the above paragraphs
[0014] to
[0025] .
[0029] As for glycyrrhizic acid and / or its salts that can be used in the present invention, either glycyrrhizic acid or a salt of glycyrrhizic acid may be used alone, or glycyrrhizic acid and one or more salts of glycyrrhizic acid may be used in combination, or a plurality of salts of glycyrrhizic acid may be used in combination. Examples of the salt include alkali metal salts such as sodium salt and potassium salt, alkaline earth metal salts such as calcium salt and magnesium salt, ammonium salt, etc. Specifically, dipotassium glycyrrhizate, monoammonium glycyrrhizate, etc. are included.

[0030] The blending amount of glycyrrhizic acid and / or its salts is not particularly limited as long as it can exhibit the effect of suppressing the precipitation of azole antifungal agents typified by MCZ. Based on the total mass of the liquid preparation, it is preferably 0.001 to 1% by mass, more preferably 0.01 to 0.8% by mass, and still more preferably 0.01 to 0.5% by mass. Furthermore, since glycyrrhizic acid and / or its salts are known to have an anti-inflammatory effect, a dosage at which an anti-inflammatory effect can be expected is preferable. As the blending amount at which an anti-inflammatory effect is expected, for example, in the case of GK2, it is 0.05% to 0.5% by mass.
[0031] Here, the "precipitation inhibition effect" in this specification refers to the effect of suppressing the precipitation of azole antifungal agents and maintaining the stability of a solution containing azole antifungal agents and nonionic surfactants over a certain period. In this specification, a substance showing such an effect is referred to as a "precipitation inhibitor". More specifically, the presence or absence of the precipitation inhibition effect can be determined, for example, by observing the presence or absence of precipitation of insoluble matter when a liquid preparation in which an azole antifungal agent is dissolved is placed in a sealed container and left at 0°C for 2 weeks. The presence or absence of precipitation of insoluble matter can usually be easily determined visually.
[0032] Also, as one aspect of the present invention, glycyrrhizic acid and / or its salts exhibit the effect of reducing the amount of surfactant necessary for suppressing the precipitation of crystals of azole antifungal agents. The blending amount of glycyrrhizic acid and / or its salts is the same as the range described above.
[0033] In the liquid preparation of the present invention, the content ratio of azole antifungal agent: glycyrrhizic acid and / or its salts is not particularly limited as long as it can exhibit the precipitation inhibition effect of the azole antifungal agent, and in terms of mass ratio, it is preferably 1:0.01 to 100, more preferably 1:0.1 to 50, and even more preferably 1:0.1 to 10.
[0034] The liquid preparation of the present invention may further contain a polyhydric alcohol. The addition of the polyhydric alcohol can be expected to have effects such as suppressing the scattering of the powder of the azole antifungal agent during production and preventing adhesion to the container, and facilitating formulation. The polyhydric alcohol is not particularly limited as long as it does not interfere with the effects of the present invention, and examples thereof include diols. Examples of the above diols include butanediol, propanediol (1,3-propanediol, 1,2-propanediol), pentanediol, hexanediol, or octanediol, etc., and 1,2-propanediol (propylene glycol) is preferred. When using diols, the blending amount is not particularly limited, but based on the total mass of the liquid preparation, it is preferably 0.1 to 20% by mass, more preferably 1 to 15% by mass, and still more preferably 2 to 10% by mass. When using diols and the diol is propylene glycol, the blending amount is preferably 0.1 to 15% by mass, more preferably 1 to 10% by mass, and still more preferably 2 to 9% by mass based on the total mass of the liquid preparation.
[0035] In addition to the above-described components, the liquid preparation of the present invention can also contain, within a range not impairing the object of the present invention, active ingredients such as humectants, cooling agents, anti-inflammatory agents, ultraviolet absorbers, antioxidants, preservatives, chelating agents, pH adjusters, solubilizers, solubilizing aids, stabilizers, fragrances, dyes, etc. Specifically, salicylic acid, allantoin, tranexamic acid, piroctone olamine, isopropylmethylphenol, etc. can be mentioned. Furthermore, the liquid preparation of the present invention contains water as a solvent in addition to the above-described components. As the water, purified water can be used. The amount of water contained in the liquid preparation is usually the remainder obtained by subtracting the total amount of the above-described components from 100% by mass. The amount of water contained in the liquid preparation of the present invention is usually 50 to 99.9% by mass, preferably 60 to 99% by mass, more preferably 70 to 99% by mass, and still more preferably 80 to 99% by mass based on the total mass of the liquid preparation.
[0036] The liquid preparation of the present invention can be prepared, for example, by mixing the above components in water such as purified water, and performing treatments such as heating and stirring as necessary to dissolve the above components. The obtained liquid preparation can be adjusted to a desired pH by adding a pH adjuster as necessary. As the pH adjuster, organic acids and organic acid salts having a buffering action are generally used. Specifically, for example, citric acid, sodium citrate, anhydrous citric acid, succinic acid, phosphoric acid, etc. can be used. As a specific preparation method of the liquid preparation of the present invention, although not limited thereto, for example, an azole antifungal agent is dissolved in a solution containing a nonionic surfactant and, if desired, a polyhydric alcohol, heated if necessary, and stirred. Separately, a solution in which glycyrrhizic acid or the like is dissolved in an aqueous solvent is heated if necessary, added to the solution in which the azole antifungal agent is dissolved, and purified water is added while stirring to prepare the liquid preparation of each formulation. Here, the "aqueous solvent" in the present specification refers to a solvent containing water, and is not particularly limited. For example, water, purified water, distilled water, physiological saline, phosphate buffered saline, etc. may be mentioned, and alcohol, polyhydric alcohol, etc. may be contained as long as the effects of the present invention are not affected.

[0040] Test Example 1: Effects of GK2 and Nonionic Surfactant on the Solubility of MCZ A liquid preparation was prepared so that the total amount was 100% by mass according to the formulation amounts described in Table 1. Specifically, the azole antifungal agent was dissolved in a solution containing a nonionic surfactant and optionally PG, heated to about 80 °C if necessary, and stirred using a stirrer to confirm complete dissolution. Separately, a solution of glycyrrhizic acid or the like dissolved in water was heated to about 80 °C if necessary, and after confirming complete dissolution, this was added to the solution in which the azole antifungal agent was dissolved. Further, purified water was added while stirring to prepare a liquid preparation for each formulation. The liquid preparation used for the evaluation test was transferred to a glass-sealed container, and after visually confirming that all components were completely dissolved, the sealed container was placed in an environment at 0 °C for a predetermined period to observe whether precipitation of the azole antifungal agent was observed. The presence or absence of precipitation of the azole antifungal agents MCZ or ketoconazole was determined according to the following criteria. 〇: No insoluble matter was precipitated. △: A small amount of insoluble matter was precipitated. ×: Insoluble matter was precipitated. Note that the amounts of each component in the table represent mass % based on the total mass of the liquid preparation.
[0041]
Table 1
[0042] Result: By incorporating GK2, precipitation of MCZ could be suppressed with a small amount of nonionic surfactant. That is, it was found that the MCZ-containing liquid preparation could be stably stored for a long period by incorporating a small amount of nonionic surfactant and GK2.
[0043] Test Example 2: Influence of the Blending Amounts of Glycyrrhizic Acid and GK2 According to the method of Test Example 1 and the like, a liquid preparation having the composition shown in Table 2 was prepared, and the presence or absence of precipitation of MCZ in the liquid preparation was observed for a predetermined period, and the determination was made in the same manner as in Test Example 1.
[0044] [Table 2]
[0045] Result: Even when the blending amount of GK2 was small, precipitation of MCZ could be suppressed. Glycyrrhizic acid also suppressed the precipitation of MCZ in a small amount in the same manner. Further, as a result of observing for two months, the same results as those for two weeks were obtained.
[0046] Test Example 3: Influence of the type of nonionic surfactant According to the method of Test Example 1 and the like, a liquid preparation was prepared with the blending amounts described in Tables 3-1 and 3-2, and then the presence or absence of precipitation of MCZ in the liquid preparation was observed for a predetermined period, and the determination was made in the same manner as in Test Example 1.
[0047] [Table 3] [Table 4]
[0048] Result: Regardless of the type of nonionic surfactant, for 12 nonionic surfactants, an effect of suppressing MCZ precipitation by blending GK2 was recognized (Table 3-1). Further, as a result of observing for two months the same results as those for two weeks were obtained.
[0049] Test Example 4: Effects of various anti-inflammatory components on the MCZ precipitation inhibitory effect According to the method of Test Example 1 and the like, a liquid preparation was prepared with the blending amounts described in Table 4, and then the presence or absence of precipitation of miconazole in the liquid preparation was observed for a predetermined period, and the determination was made in the same manner as in Test Example 1.
[0050] [Table 5]
[0051] Result: It was found that the effect of suppressing the precipitation of MCZ by the addition of GK2 was not affected by the presence or absence of propylene glycol (PG) (Examples 21 and 22). Also, even when only PG was added instead of GK2, the precipitation of MCZ could not be suppressed (Comparative Example 21). Even when tranexamic acid or allantoin, which are anti-inflammatory components, were added instead of GK2, the precipitation of miconazole could not be suppressed (Comparative Examples 19 and 20). As a result of further separate investigations, it was shown that the effect of suppressing the precipitation of MCZ could not be obtained only by adjusting the pH of the solution, and it was found that this is a specific action of glycyrrhizic acid and / or its salts. In other words, it was suggested that glycyrrhizic acid and / or its salts have a synergistic and specific effect of suppressing the precipitation of MCZ with nonionic surfactants.
[0052] Test Example 5: Influence of the type of azole antifungal agent According to the method of Test Example 1 et al., after preparing a solution with the compounding amounts described in Table 5, the presence or absence of precipitation of MCZ or ketoconazole in the solution was observed for a predetermined period, and the determination was made in the same manner as in Test Example 1.
[0053]
Table 6
[0054] Result: For ketoconazole as well as for MCZ, an effect of suppressing precipitation by GK2 was observed (Example 23). Also, as a result of observing for two months, the same results as those for two weeks were obtained. Therefore, it was suggested that the precipitation of azole antifungal agents can be suppressed by adding GK2 regardless of the type of azole antifungal agent. That is, it was suggested that by adding GK2, a solution containing an azole antifungal agent can be stably stored for a long period even under conditions where the amount of nonionic surfactant is small.
