Abstract

PROBLEM TO BE SOLVED: To inhibit the discoloration of Chinese medicine extract formulations.SOLUTION: This invention relates to a solid formulation comprising Chinese medicine extracts and polyvinyl acetate.

Description

本発明は、漢方エキスを含有する固形製剤に関する。   The present invention relates to a solid preparation containing a Kampo extract.

医薬品における性状は、その品質項目として必須である。中でも、製剤の経時的な色の変化は服用する者に心理的に大きな不安感を与える要因にもなるため、その外観上の変色を抑えることは、医薬品やサプリメント等の開発にあたって重要な課題の一つである。特に漢方エキスの場合は、天然物の抽出成分で、種々の微量成分を多様に含有し、またその構造が未知の成分も含まれることなどから、通常の医薬品に比べ品質管理が難しく、保存条件によっては、エキスの変色やカビの発生など漢方エキスの品質低下がみられるなど、エキスの製造過程や製剤化工程において取扱いが困難であることが課題となっている。   Properties in pharmaceutical products are essential as quality items. In particular, the color change over time of the formulation can be a factor that gives psychological anxiety to the person taking the drug, so suppressing the discoloration of the appearance is an important issue in the development of pharmaceuticals and supplements. One. In the case of Kampo extract, in particular, it is a natural product extraction component that contains various trace components in various ways and includes components whose structure is unknown. In some cases, the quality of the Kampo extract is degraded such as discoloration of the extract and generation of mold, which makes it difficult to handle the extract in the manufacturing process and formulation process.

一般的に漢方エキスの変色の原因は、エキスの高い吸湿性にあると考えられており、その変色の原因となる吸湿を抑制する方法としては、例えば、製造場所や保管場所における温湿度の徹底した管理が挙げられ、実際の製造現場においてもそのような管理が行われている。しかし、この方法においては、作業効率の低下、管理コストの増大等の問題がある。   The cause of discoloration of Kampo extract is generally considered to be due to the high hygroscopicity of the extract. As a method for suppressing the moisture absorption that causes the discoloration, for example, thorough temperature and humidity at the manufacturing and storage locations Such management is also carried out at actual manufacturing sites. However, this method has problems such as a decrease in work efficiency and an increase in management cost.

また、製造後の漢方エキスを配合した製剤の変色を抑制する方法としては、製剤を保存する容器内に乾燥剤を使用したり、製剤の包装材質を防湿素材にする工夫などの方法がとられている(非特許文献1)。   In addition, as a method of suppressing discoloration of a preparation containing a Kampo extract after manufacture, methods such as using a desiccant in the container for storing the preparation or making the packaging material of the preparation into a moisture-proof material are taken. (Non-Patent Document 1).

一方、漢方エキスを配合した製剤における吸湿の抑制方法としては、特許文献1〜3等、漢方エキスに種々の医薬品添加剤を配合することが知られている。しかし、漢方エキス製剤のべたつきを抑制し、その製剤における崩壊性、硬度、耐摩損度等の改善が図られているに止まっており、よりデリケートに影響を受けやすい変色の改善にまでは至っておらず、なお漢方エキスの変色を抑えることには課題を残していた。   On the other hand, as a method for suppressing moisture absorption in a preparation containing a Kampo extract, it is known that various pharmaceutical additives are blended with a Kampo extract such as Patent Documents 1 to 3. However, the stickiness of Kampo extract preparations has been suppressed, and the disintegration, hardness, abrasion resistance, etc. of the preparations have been improved, and even the discoloration that is more susceptible to delicate effects has not been achieved. However, there was still a problem in suppressing the discoloration of the Kampo extract.

一方、ポリ酢酸ビニルは、コーティング剤、可塑剤、結合剤、光沢化剤等として、医薬品や化粧料等に用いられているが、漢方に対する作用については、知られていない。   On the other hand, polyvinyl acetate is used as a coating agent, a plasticizer, a binder, a brightening agent and the like in medicines and cosmetics, but its action on Chinese medicine is not known.

漢方調剤研究、Vol.1、No.5、p23-25(1993)Kampo Preparation Research, Vol. 1, No. 5, p23-25 (1993)

本発明の課題は、簡便な方法により、上記課題を有する漢方エキスを含有する固形製剤の変色を抑制し、長期にわたり安定性に優れた漢方エキスを含有する固形製剤を提供することにある。   The subject of this invention is providing the solid formulation containing the Chinese medicine extract excellent in stability over a long term, suppressing discoloration of the solid formulation containing the Chinese medicine extract which has the said subject by a simple method.

本発明者は、漢方エキスの変色を抑制するべく鋭意検討したところ、(A)漢方エキスと(B)ポリ酢酸ビニルとを固形製剤中に含有させることにより、漢方エキスを含有する固形製剤の変色が抑制されることを見出し、本発明を完成するに至った。   As a result of intensive studies to suppress discoloration of the Kampo extract, the present inventor has included (A) Kampo extract and (B) polyvinyl acetate in the solid preparation, thereby discoloring the solid preparation containing the Kampo extract. Has been found to be suppressed, and the present invention has been completed.

具体的には本発明は、以下の固形製剤等を提供するものである。
[項1](A)漢方エキス、及び、(B)ポリ酢酸ビニルを含有する固形製剤。
Specifically, the present invention provides the following solid preparations and the like.
[Item 1] A solid preparation containing (A) Chinese medicine extract and (B) polyvinyl acetate.

[項2](A)漢方エキスが、防已黄耆湯、葛根湯、葛根湯加川キュウ辛夷、小青竜湯、当帰芍薬散、加味帰脾湯、加味逍遙散、桂枝茯苓丸、桂枝茯苓丸料加ヨク苡仁、補中益気湯、防風通聖散、牛車腎気丸、杞菊地黄丸、麻黄湯、麻黄附子細辛湯、桂枝加朮附湯、桂枝加苓朮附湯、十全大補湯、疎経活血湯、芍薬甘草湯、桂枝人参湯、桃核承気湯、甘草瀉心湯、抑肝散、抑肝散加芍薬黄連、麦門冬湯、五苓散、五虎湯、六君子湯および越婢加朮湯からなる群から選択される少なくとも1種の漢方エキスである項1記載の固形製剤。 [Claim 2] (A) Kampo extract is known as Houen-yu, Kakkon-yu, Kakone-yu Kagawa Kyu-kan, Shosei-ryu, Tokiso-Yakusan, Kami-Kai-Syu-yu, Kami-San-san, Katsushi-gan-maru, Katsushika Karasuma Yokajin, Hochuekkito, Fufutsu Seiki, Ushizurijinkimaru, Sakai Kikuchi Huangmaru, Maoyu, Maoyu Spicy Hot Spring, Keieka Kasetsuyu, Katsueka Kasuga Tsukeyu, Juzen Daiyoto, Ryokei-Kaito-yu, Shakuyakukanzo-to, Keishi-jinjin-yu, Momokure-ki-ki-to, Liquorice-shashin-to, Yokukansan, Yokukansan, Yakurensan, Yakuren, Item 2. The solid preparation according to Item 1, which is at least one kind of Chinese medicine extract selected from the group consisting of Gojosan, Gotora-to, Rokukunshi-to, and Koetsuka-ka-to.

[項7]ポリ酢酸ビニルを含有することを特徴とする、漢方エキスを含有する固形製剤の変色抑制剤。 [Item 7] A discoloration inhibitor for solid preparations containing a Kampo extract, characterized by containing polyvinyl acetate.

本発明の固形製剤は、(B)ポリ酢酸ビニルを含有するため、漢方エキスを含有する固形製剤であっても、時間経過、加熱、吸湿等による固形製剤の変色が抑制される。
本発明の方法はポリ酢酸ビニルを配合するという簡便な方法でその変色を効果的に抑えることができることから、従前防湿のために用いられてきた乾燥剤を、減量することができる。乾燥剤を使用しない場合は、製剤を保存する容器内に乾燥剤を入れる工程が不要となり、作業の効率化も図れる。また、漢方エキス製剤の包材の選択肢が広まるため、製剤設計の自由度が高まり、使用者の利便性向上や大幅なコスト削減が図れる。
また、漢方エキス製剤がマルチドーズである場合には、開封後の吸湿による変色が懸念されるが、ポリ酢酸ビニルを配合することで係る懸念も解消される。
特に本発明においては、ポリ酢酸ビニルを単に漢方エキスと混合するだけではその吸湿を十分に抑えられないにもかかわらず、その変色を抑えうることも確認しており、従来の変色抑制方法とは違うメカニズムでその変色を抑えている可能性がある。
Since the solid preparation of the present invention contains (B) polyvinyl acetate, discoloration of the solid preparation due to elapse of time, heating, moisture absorption or the like is suppressed even in the case of a solid preparation containing a Chinese medicine extract.
Since the discoloration can be effectively suppressed by the simple method of blending polyvinyl acetate in the method of the present invention, the amount of desiccant that has been used for moisture prevention can be reduced. When the desiccant is not used, the step of putting the desiccant into the container for storing the preparation is not necessary, and the work efficiency can be improved. In addition, since the choice of packaging materials for Kampo extracts is widened, the degree of freedom in designing the formulation is increased, and the convenience of the user can be improved and the cost can be greatly reduced.
Further, when the Chinese herbal extract preparation is multi-dose, there is a concern about discoloration due to moisture absorption after opening, but this concern is also eliminated by blending polyvinyl acetate.
In particular, in the present invention, it has also been confirmed that discoloration can be suppressed even though polyvinyl acetate cannot be sufficiently suppressed by simply mixing polyvinyl acetate with a Chinese medicine extract. The discoloration may be suppressed by a different mechanism.

本発明で用いられる漢方エキスとは、通常の漢方処方の原料生薬を、加熱抽出してできた液から溶媒を溜去し、加工したものである。   The Kampo extract used in the present invention is a product obtained by distilling a solvent from a liquid obtained by heating and extracting a raw herbal medicine of a normal Kampo formulation.

Test example 1 (Comparison with powder 1)
In accordance with Table 1, each component was weighed, and polyvinyl acetate (Wako Pure Chemical Industries, Ltd., MW ca 50,000) was sprayed and mixed on the dried anti-boiled water extract, and the dried product was used as a sample. The obtained sample is put in a plastic container, stored in a humidity desiccator under conditions of 25 ° C. and 60% RH for 24 hours, and then the color difference (ΔE * ab) from the sample at the start of storage is measured by spectrophotometry. Measurement was performed using a meter (CM-3500d, manufactured by Konica Minolta).

Figure 2014166994

防已黄耆湯エキスのみの検体(比較例1)よりも、ポリ酢酸ビニルを配合した検体(実施例1)の方が、色差(ΔE*ab)の値が小さく、ポリ酢酸ビニルの配合により、防已黄耆湯乾燥エキスの色の変化が抑制されることが示された。   The sample containing polyvinyl acetate (Example 1) has a smaller color difference (ΔE * ab) than the sample containing only the Kosai Hakusuito extract (Comparative Example 1), and it is It was shown that the color change of the dried antibacterial extract was suppressed.

試験例2(粉末での比較2)
表2に従い、防已黄耆湯乾燥エキス及びコリコートSR30D(ポリ酢酸ビニル 27%分散液、BASF社製)を秤量し、防已黄耆湯乾燥エキスにコリコートSR30Dを噴霧、混合し、乾燥したものを試料とした。得られた試料を、プラスチック容器に入れ、25℃・60%RH条件下の調湿デシケータ内に、24時間保存した後、保存開始時の試料との色差(ΔE*ab)を、試験例1と同様に、分光測色計(CM−3500d、コニカミノルタ製)を用いて測定した。

Test Example 2 (Comparison 2 with powder)
In accordance with Table 2, weighed Kyo-Kousui-to dry extract and Kollicoat SR30D (polyvinyl acetate 27% dispersion, manufactured by BASF), sprayed Koricoat SR30D to Kojiko-yu dried extract, mixed and dried Was used as a sample. The obtained sample was put in a plastic container and stored in a humidity desiccator under conditions of 25 ° C. and 60% RH for 24 hours, and then the color difference (ΔE * ab) from the sample at the start of storage was tested. In the same manner as above, measurement was performed using a spectrocolorimeter (CM-3500d, manufactured by Konica Minolta).
Figure 2014166994

試験例1と同様に、防已黄耆湯エキスのみの検体(比較例2)よりも、ポリ酢酸ビニルを配合した検体(実施例2、3)の方が、色差(ΔE*ab)の値が小さく、ポリ酢酸ビニルの配合により、防已黄耆湯乾燥エキスの色の変化が抑制されることが示された。また、ポリ酢酸ビニルの配合量を変えても、防已黄耆湯乾燥エキスの色の変化は抑制された。
なお、実施例2と実施例3とを対比するとき、両者のポリ酢酸ビニルの含有量の違いに比して色の変化の抑制の差が少ないことから、ポリ酢酸ビニルは一定量配合すれば(例えば、0.5%程度)、十分な効果が得られることが示唆された。
As in Test Example 1, the color difference (ΔE * ab) value is greater for the specimens (Examples 2 and 3) containing polyvinyl acetate than for the specimens containing only Koho Koreito extract (Comparative Example 2). It was shown that the change in the color of the dried extract of Kosai Koreito was suppressed by adding polyvinyl acetate. Moreover, even if the blending amount of polyvinyl acetate was changed, the change in the color of the dried anti-boiled water extract was suppressed.
In addition, when Example 2 and Example 3 are compared, since there is little difference in suppression of color change compared to the difference in the content of both polyvinyl acetates, if a certain amount of polyvinyl acetate is blended (For example, about 0.5%) suggests that a sufficient effect can be obtained.

試験例3(粉末での比較3)
表3に従い、漢方乾燥エキス(加味逍遥散乾燥エキスもしくは六君子湯乾燥エキス)、及び、コリコートSR30D(ポリ酢酸ビニル 27%分散液、BASF社製)を秤量し、漢方乾燥エキスにコリコートSR30Dを噴霧、混合し、乾燥したものを試料とした。得られた試料を、プラスチック容器に入れ、25℃・60%RH条件下の調湿デシケータ内に、24時間保存した後、保存開始時の試料との色差(ΔE*ab)を、試験例1と同様に、分光測色計(CM−3500d、コニカミノルタ製)を用いて測定した。

Test Example 3 (Comparison 3 with powder)
In accordance with Table 3, weighed the Kampo dried extract (Kamizo Harukasan dried extract or Rikkunshiyu dried extract) and Kollicoat SR30D (polyvinyl acetate 27% dispersion, manufactured by BASF) and sprayed Koricoat SR30D onto the Kampo dried extract. Samples were mixed and dried. The obtained sample was put in a plastic container and stored in a humidity desiccator under conditions of 25 ° C. and 60% RH for 24 hours, and then the color difference (ΔE * ab) from the sample at the start of storage was tested. In the same manner as above, measurement was performed using a spectrocolorimeter (CM-3500d, manufactured by Konica Minolta).
Figure 2014166994

漢方エキスの種類を変えても、試験例1、2と同様に、漢方エキスのみの検体(比較例3、4)よりも、ポリ酢酸ビニルを配合した検体(実施例4、5)の方が、色差(ΔE*ab)の値が小さく、ポリ酢酸ビニルの配合により、漢方乾燥エキスの色の変化が抑制され、種々の漢方エキスで変色抑制効果を得られることが示唆された。   Even if the type of Kampo extract is changed, the specimens (Examples 4 and 5) containing polyvinyl acetate are more similar to the specimens of the Kampo extract alone (Comparative Examples 3 and 4) as in Test Examples 1 and 2. The value of the color difference (ΔE * ab) was small, and it was suggested that the color change of the Kampo dried extract was suppressed by blending polyvinyl acetate, and the discoloration suppressing effect was obtained with various Kampo extracts.

試験例4(錠剤での比較)
下記の方法に従い、漢方エキスとポリ酢酸ビニルを含む錠剤(実施例6)と漢方エキスを含み、ポリ酢酸ビニルを含まない錠剤(比較例5)を調製した。

Test Example 4 (Comparison with tablets)
According to the following method, a tablet containing Kampo extract and polyvinyl acetate (Example 6) and a tablet containing Kampo extract but not containing polyvinyl acetate (Comparative Example 5) were prepared.
(Example 6)
In accordance with Table 4, 3200 parts by weight of dried antibacterial hot extract, 56 parts by weight of Kollicoat SR30D (polyvinyl acetate 27% dispersion, manufactured by BASF) (50.4 parts by weight as polyvinyl acetate), light anhydrous silicic acid 32 The parts by weight were weighed, and these two components were granulated with a fluid bed granulator. The obtained granulated product was pulverized and sized by a com mill to obtain a sized powder. A mixture of these granulated powder and other components (magnesium aluminate metasilicate, crystalline cellulose, magnesium stearate) using a mixer was used as a tableting powder. The obtained powder for tableting was tableted at a main pressure of 10 kN using a 10 mm diameter mortar with a tableting machine to obtain 450 mg of tablets per tablet.
(Comparative Example 5)
According to Table 4, each component was weighed and then mixed using a mixer to obtain a tableting powder. The obtained powder for tableting was tableted at a main pressure of 10 kN using a 10 mm diameter mortar with a tableting machine to obtain 450 mg of tablets per tablet.

比較例5及び実施例6の錠剤の各10錠を、25℃・60%RH条件下の調湿デシケータ内に、3時間もしくは24時間保存した後、保存開始時の錠剤との色差(ΔE*ab)を、試験例1と同様に、分光測色計(CM−3500d、コニカミノルタ製)を用いて測定した。

Figure 2014166994
Each of the 10 tablets of Comparative Example 5 and Example 6 was stored in a humidity-controlled desiccator under conditions of 25 ° C. and 60% RH for 3 hours or 24 hours, and then the color difference from the tablet at the start of storage (ΔE * ab) was measured using a spectrocolorimeter (CM-3500d, manufactured by Konica Minolta) in the same manner as in Test Example 1.

Figure 2014166994

錠剤とした場合にも、試験例1〜3と同様に、防已黄耆湯エキスのみの検体(比較例5)よりも、ポリ酢酸ビニルを配合した検体(実施例6)の方が、色差(ΔE*ab)の値が小さく、ポリ酢酸ビニルの配合により、防已黄耆湯乾燥エキスの色の変化が抑制されることが示された。   Even in the case of tablets, as in Test Examples 1 to 3, the sample (Example 6) in which polyvinyl acetate was blended was different in color difference from the sample containing only Koho Koreito extract (Comparative Example 5). The value of (ΔE * ab) was small, and it was shown that the change in the color of the dried anti-Kojito extract was suppressed by the blending of polyvinyl acetate.

試験例5(吸湿性の確認)
実施例6、比較例5について、吸湿性の指標として重量変化率を、固形製剤の特性として硬度、および崩壊試験による崩壊時間を測定した。なお、保存は25℃・60%RH条件下の調湿デシケータ内で行った。
結果は表4に示すように、ポリ酢酸ビニルを含有する実施例6では3時間および24時間後重量が1.44%および3.47%それぞれ増加したのに対し、ポリ酢酸ビニルを含まない比較例5では0.91%および2.75%であり、ポリ酢酸ビニルの配合により、吸湿性は改善されなかった。このことは、上記試験例1および試験例2の粉末でも同じ傾向が認められた。
一般に、漢方エキスは吸湿性が高いことが知られており、吸湿に伴い、つまり、漢方エキス中に水が取り込まれる(水分含有量があがる)ことにより、色も変化していくと考えられている。しかし、本発明の固形製剤では、ポリ酢酸ビニルの添加により吸湿性が改善されないにも関わらず、ポリ酢酸ビニル添加により色の変化は起こりにくくなっていることが確認されており、ポリ酢酸ビニルの色の変化を抑制する効果は吸湿性の改良によるものではなく、かつ、ポリ酢酸ビニルの色の変化を抑制する効果は、これまで考えられてきたようなメカニズムを介するのではなく、予想外のものであると考えられた。
Test Example 5 (Confirmation of hygroscopicity)
For Example 6 and Comparative Example 5, the rate of weight change was measured as a hygroscopic index, the hardness as a characteristic of the solid preparation, and the disintegration time by a disintegration test. Storage was performed in a humidity desiccator under conditions of 25 ° C. and 60% RH.
The results are shown in Table 4, in Example 6 containing polyvinyl acetate, the weight increased by 1.44% and 3.47% after 3 hours and 24 hours, respectively, while no comparison was made without polyvinyl acetate. In Example 5, they were 0.91% and 2.75%, and the hygroscopicity was not improved by the blending of polyvinyl acetate. The same tendency was observed in the powders of Test Example 1 and Test Example 2 described above.
In general, Kampo extracts are known to have high hygroscopicity, and it is thought that the color changes as moisture is absorbed, that is, when water is taken into the Kampo extract (the water content increases). Yes. However, in the solid preparation of the present invention, although the hygroscopicity is not improved by the addition of polyvinyl acetate, it has been confirmed that the color change is hardly caused by the addition of polyvinyl acetate. The effect of suppressing the color change is not due to the improvement of hygroscopicity, and the effect of suppressing the color change of polyvinyl acetate is not via the mechanism that has been considered so far, but it is unexpected. It was considered a thing.
