Description

【0001】
【発明の属する技術分野】
この発明は、錠剤用滑沢剤組成物に関し、更に詳しくは、打錠性に優れ、錠剤硬度が高く、しかも崩壊性の良好な錠剤を得ることができる錠剤用滑沢剤組成物に関する。
【0002】
【従来の技術】
従来より、医薬品、医薬部外品、食品等の分野に於いて、錠剤を調製する場合には錠剤用滑沢剤が使用されている。このような錠剤用滑沢剤の一種として、ショ糖脂肪酸エステルがある。錠剤用滑沢剤に使用されるショ糖脂肪酸エステルとしては、特定の構成脂肪酸を有するものや、特定のエステル化度、酸価、HLB(親水性疎水性バランス)値等を配合したものが知られている(例えば、特許文献1、特許文献2、特許文献4及び特許文献5)。また、錠剤の崩壊を遅延させるために、特定のHLB(親水性疎水性バランス)値のショ糖脂肪酸エステルと、ステアリン酸マグネシウム、ステアリン酸カルシウム等のステアリン酸塩とを配合することが検討されている(例えば、特許文献3)。これらのショ糖脂肪酸エステルを含有する滑沢剤を使用すれば、ある程度の打錠性、錠剤硬度、及び崩壊性を得ることができるが、未だ満足のできる錠剤を得ることができる錠剤用滑沢剤組成物は得られていない。
【0003】
また、ステアリン酸マグネシウム及びステアリン酸カルシウムは、良好な打錠成型性を示すことから汎用されているが、その一方で、成形された錠剤の崩壊時間が遅くなり、かつ錠剤硬度が低くなるという欠点がある。また、打錠成型性が低い処方での錠剤成形に於いては滑沢剤の使用量を増やす場合があるが、滑沢剤を多く使用すると錠剤硬度が低下し、崩壊時間にも大きく影響することがあるばかりではなく、却って逆効果となり、打錠成型性が低下することもある。その場合には、賦形剤や崩壊剤、その他添加物等を添加して処方を変更し、又は打錠成形の条件を変更等の措置をとる必要が生じる。

【発明が解決しようとする課題】
本発明は、このような従来技術の問題点を解決するために為されたものであり、本発明の目的は、良好な打錠成型性を発揮し、錠剤硬度が高く、しかも崩壊性の良好な錠剤を得ることができる錠剤用滑沢剤組成物を提供することである。
【0006】
【課題を解決するための手段】
本発明は、滑沢成分としてステアリン酸マグネシウム、ステアリン酸カルシウム等のステアリン酸塩と、所定のエステル化度を有するショ糖脂肪酸エステルを所定の配合割合で配合することにより、良好な打錠成型性を維持しつつ、硬度が高く、崩壊性の良好な錠剤を調製し得ることを見出したことに基づいて為されたものである。
【0007】
即ち、本発明の錠剤用滑沢剤組成物は、ショ糖脂肪酸エステルと炭素数16〜22の脂肪酸塩とを含有する錠剤用滑沢剤組成物であって、前記ショ糖脂肪酸エステルは、20〜50重量%のエステル化度1〜3のショ糖脂肪酸エステルと、30〜60重量%のエステル化度4〜6のショ糖脂肪酸エステルと、20重量%以下のエステル化度7〜8のショ糖脂肪酸エステルとにより構成されていることを特徴とする。
【0008】
ここで、上記炭素数16〜22の脂肪酸塩は、良好な打錠成型を発揮するとともに、上記ショ糖脂肪酸エステルのうちのエステル化度の高い成分も打錠に際しての打錠機への付着を防止して、得られる錠剤の成型性を向上させると考えられ、また、エステル化度の低い成分が結着性を高めることにより、錠剤の硬度を向上させる効果を発揮するものと考えられる。
【0009】
本発明の一実施形態では、前記ショ糖脂肪酸エステルと前記炭素数16〜22の脂肪酸塩とを、重量比で(ショ糖脂肪酸エステル)/(炭素数16〜22の脂肪酸塩)=20/80〜80/20の範囲で含有している。
【0010】
また、本発明の他の実施形態では、前記ショ糖脂肪酸エステルは、その構成脂肪酸のうち70重量%以上が炭素数16以上の飽和脂肪酸との単独又は混合エステルである。
【0011】
更に、前記炭素数16〜22の脂肪酸塩は、ステアリン酸塩であり、前記ステアリン酸塩は、ステアリン酸マグネシウム又はステアリン酸カルシウムである実施形態もあり得る。ここで、前記ステアリン酸マグネシウムは、植物を原料とする脂肪酸で構成されているものを採用することができる。
【0012】
【発明の実施の形態】
以下、本発明の実施の形態について説明する。本発明の錠剤用滑沢剤組成物は、エステル化度1(モノエステル)からエステル化度8(オクタエステル)までのショ糖脂肪酸エステルのうち、上述のように、親水性の高いエステル化度1〜3のショ糖脂肪酸エステルの合計の含有量が20〜50重量%であり、エステル化度4〜6のショ糖脂肪酸エステルの合計の含有量が30〜60重量%であり、更に、親油性の高いエステル化度7〜8のショ糖脂肪酸エステルの合計の含有量が20重量%以下である。
【0013】
エステル化度7〜8のショ糖脂肪酸エステルは、打錠に際して打錠機への付着を防止する滑剤としての機能を果たすものであり、この添加量が20重量%より低ければ、打錠機への粉体の付着を防止するという効果が低くなるので好ましくない。また、エステル化度4〜6のショ糖脂肪酸エステルの合計の含有量は30〜60重量%の範囲であり、この含有量がこの範囲を外れると打錠成形性が低下するだけでなく、適度な硬度の錠剤を調製することができなくなるので好ましくない。更に、エステル化度1〜3のショ糖脂肪酸エステルは、エステル化度の高いショ糖脂肪酸エステルのみでは錠剤が脆くなり、保存中に欠けが生じ易くなるのを防止する機能を果たし、その合計の含有量は20〜50重量%である。この含有量が20重量%より小さくなると、得られる錠剤が脆くなり、保存中に欠けが生じ易くなり、また、この含有量が50重量%より多いと、打錠機への粉体の付着を防止する効果が低下するので好ましくない。
【0014】
また、本発明に於いては使用されるショ糖脂肪酸エステルは、その構成脂肪酸のうち70重量%以上が炭素数16以上の飽和脂肪酸との単独又は混合エステルであることが好ましい。ショ糖脂肪酸エステルの構成脂肪酸が上記範囲を外れると、打錠成形性が低下し、適切な硬度の錠剤を調製することが困難になる傾向となる。
【0015】
本発明の錠剤用滑沢剤組成物に於いては、ショ糖脂肪酸エステルに加えて炭素数16〜22の脂肪酸塩を含有している。この脂肪酸塩としてはステアリン酸塩が好ましく、なかでもステアリン酸マグネシウム及びステアリン酸カルシウムが好ましい。
【0016】
ショ糖脂肪酸エステルとステアリン酸塩の配合比率は、要求される錠剤用滑沢剤組成物としての物性に応じて変更すればよいが、良好な打錠成型性を維持しつつ、適度な硬度と崩壊性を有する錠剤を調製するためには、重量比でショ糖脂肪酸エステル/炭素数16〜22の脂肪酸塩=80/20〜20/80の範囲であることが好ましい。ショ糖脂肪酸エステルが80重量%以上であると打錠時の粉体の流動性が低下し、原料粉体が臼へ速やかに充填されず、スムーズに打錠できないことがある。また、炭素数16〜22の脂肪酸塩が80重量%以上であると、硬度が低く、かつ崩壊速度の遅い錠剤になることがある。
【0017】
本発明の錠剤用滑沢剤組成物の使用量は、打錠成型性の面から、錠剤全量に対して、0.2〜10重量%が適切であり、0.5〜5.0重量%の範囲がより好ましい。
【0018】
また、本発明の錠剤用滑沢剤組成物には、錠剤成型性と錠剤物性に影響を与えない範囲で、滑沢成分として、タルク、グリセリン脂肪酸エステル、ポリグリセリン脂肪酸エステル、硬化油、ステアリン酸、ステアリン酸アルミニウム等を添加してもよい。
【0019】
なお、上記のようなエステル化度の分布を有するショ糖脂肪酸エステルは、エステル化度の低いショ糖脂肪酸エステルと、エステル化度の高いショ糖脂肪酸エステルとを混合することにより得られる。エステル化度の低いショ糖脂肪酸エステルとエステル化度の高いショ糖脂肪酸エステルは、通常のエステル化反応によりそれぞれ別々に製造することができる。
【0020】

表1に示すエステル化度の組成のショ糖脂肪酸エステルA〜Eと、ステアリン酸マグネシウムとを用いて、表2に示す実施例1〜3と比較例1〜8の錠剤用滑沢剤組成物を調製した。また、表2には、各ショ糖脂肪酸エステルA〜E及びステアリン酸マグネシウムを構成する脂肪酸と、表1の組成から求めたエステル化度の組成を示してある。なお、表2の実施例1〜3と比較例1〜8の数値は、配合重量%を示している。

(錠剤の硬度)
錠剤の硬度は、モンサント硬度計を使用して測定した。錠剤の好ましい硬度の範囲は、3〜7kgである。硬さの値が小さいと保存中に錠剤が壊れやすくなり、大きいと後述する崩壊性の試験に於ける崩壊時間が長くなる。

(崩壊性試験)
日本薬局方崩壊性試験装置を使用し、精製水中で錠剤が完全に崩壊するまでの時間を測定した。崩壊時間の適度な範囲は、一般的には3分〜10分である。崩壊時間が長いと、例えば胃袋内で崩壊しないために吸収が悪くなり、崩壊時間が短いと、錠剤が割れ易くなる。

【発明の効果】
本発明の錠剤用滑沢剤組成物は、滑沢成分として、ステアリン酸マグネシウム、ステアリン酸カルシウム等のステアリン酸塩と、所定のエステル化度を有するショ糖脂肪酸エステルを所定の割合で含有しているので、錠剤の原料粉末に添加すれば優れた打錠成型性を発揮し、硬度が高く、しかも崩壊性の良好な錠剤を調製することができる。[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a lubricating composition for tablets, and more particularly, to a lubricating composition for tablets capable of obtaining tablets having excellent tableting properties, high tablet hardness, and good disintegration properties.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, in the fields of pharmaceuticals, quasi-drugs, foods, and the like, a tablet lubricant has been used when preparing tablets. One such tablet lubricant is sucrose fatty acid ester. As the sucrose fatty acid ester used in the tablet lubricant, those having a specific constituent fatty acid and those containing a specific degree of esterification, acid value, HLB (hydrophilic-hydrophobic balance) value, and the like are known. (For example, Patent Literature 1, Patent Literature 2, Patent Literature 4, and Patent Literature 5). Also, in order to delay the disintegration of tablets, it has been studied to mix a sucrose fatty acid ester having a specific HLB (hydrophilic / hydrophobic balance) value with a stearate such as magnesium stearate and calcium stearate. (For example, Patent Document 3). When a lubricant containing these sucrose fatty acid esters is used, tableting properties, tablet hardness, and disintegration to some extent can be obtained, but a tablet lubricant that can still obtain satisfactory tablets can be obtained. No agent composition was obtained.
[0003]
In addition, magnesium stearate and calcium stearate are widely used because they exhibit good tableting moldability, but on the other hand, the disintegration time of the formed tablet is slow, and the drawback that the tablet hardness is low. is there. In addition, in tablet molding with a formulation having low tableting moldability, the amount of lubricant used may be increased, but if a large amount of lubricant is used, the tablet hardness decreases and the disintegration time is greatly affected. In addition to the above, the effect may be adversely affected and tableting moldability may be reduced. In this case, it is necessary to change the formulation by adding excipients, disintegrants, and other additives, or to take measures such as changing the conditions for tableting.

[Problems to be solved by the invention]
The present invention has been made to solve such problems of the prior art, and an object of the present invention is to exhibit good tableting moldability, high tablet hardness, and good disintegration. It is an object of the present invention to provide a lubricating composition for tablets capable of obtaining a stable tablet.
[0006]
[Means for Solving the Problems]
The present invention provides good tableting moldability by blending a stearate such as magnesium stearate or calcium stearate as a lubricating component and a sucrose fatty acid ester having a predetermined degree of esterification in a predetermined mixing ratio. This is based on the finding that a tablet having high hardness and good disintegrability can be prepared while maintaining the same.
[0007]
That is, the lubricant composition for tablets of the present invention is a lubricant composition for tablets containing a sucrose fatty acid ester and a fatty acid salt having 16 to 22 carbon atoms. Sucrose fatty acid esters having a degree of esterification of 1 to 50% by weight, sucrose fatty acid esters having a degree of esterification of 4 to 6 having a degree of esterification of 30 to 60% by weight, and sucrose fatty acid esters having a degree of esterification of not more than 20% by weight. And a sugar fatty acid ester.
[0008]
Here, the fatty acid salt having 16 to 22 carbon atoms exerts good tablet molding, and the component having a high degree of esterification of the sucrose fatty acid ester adheres to the tableting machine at the time of tableting. It is considered that the above-mentioned effect is improved to improve the moldability of the obtained tablet, and that a component having a low degree of esterification enhances the binding property, thereby exerting the effect of improving the hardness of the tablet.
[0009]
In one embodiment of the present invention, the sucrose fatty acid ester and the fatty acid salt having 16 to 22 carbon atoms are in a weight ratio of (sucrose fatty acid ester) / (fatty acid salt having 16 to 22 carbon atoms) = 20/80. It is contained in the range of ~ 80/20.
[0010]
Further, in another embodiment of the present invention, the sucrose fatty acid ester is a single or mixed ester of a saturated fatty acid having 16 or more carbon atoms in which 70% by weight or more of the constituent fatty acids is contained.
[0011]
Further, in some embodiments, the fatty acid salt having 16 to 22 carbon atoms is a stearate, and the stearate is magnesium stearate or calcium stearate. Here, as the magnesium stearate, those composed of fatty acids made from plants can be used.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described. As described above, the lubricant composition for tablets of the present invention has a high degree of hydrophilicity among sucrose fatty acid esters having a degree of esterification of 1 (monoester) to 8 (octaester). The total content of 1 to 3 sucrose fatty acid esters is 20 to 50% by weight, the total content of sucrose fatty acid esters having a degree of esterification of 4 to 6 is 30 to 60% by weight, The total content of sucrose fatty acid esters having a high oiliness and a degree of esterification of 7 to 8 is 20% by weight or less.
[0013]
The sucrose fatty acid ester having a degree of esterification of 7 to 8 functions as a lubricant for preventing sticking to the tableting machine at the time of tableting. This is not preferred because the effect of preventing the adhesion of powder is reduced. Further, the total content of sucrose fatty acid esters having a degree of esterification of 4 to 6 is in the range of 30 to 60% by weight. It is not preferable because it is impossible to prepare a tablet having a high hardness. Furthermore, the sucrose fatty acid esters having a degree of esterification of 1 to 3 have a function of preventing the tablet from becoming brittle with only the sucrose fatty acid ester having a high degree of esterification and preventing the chip from being easily generated during storage, and The content is 20 to 50% by weight. When the content is less than 20% by weight, the obtained tablet becomes brittle and chipping easily occurs during storage, and when the content is more than 50% by weight, the powder adheres to the tableting machine. This is not preferred because the effect of preventing it is reduced.
[0014]
Further, the sucrose fatty acid ester used in the present invention is preferably a single or mixed ester of a saturated fatty acid having 16 or more carbon atoms in which at least 70% by weight of the constituent fatty acids is used. If the constituent fatty acids of the sucrose fatty acid ester are outside the above range, the tableting formability will decrease, and it tends to be difficult to prepare tablets having an appropriate hardness.
[0015]
The lubricant composition for tablets of the present invention contains a fatty acid salt having 16 to 22 carbon atoms in addition to the sucrose fatty acid ester. As the fatty acid salt, a stearate is preferable, and among them, magnesium stearate and calcium stearate are preferable.
[0016]
The mixing ratio of the sucrose fatty acid ester and the stearic acid salt may be changed according to the required physical properties of the tablet lubricant composition, while maintaining good tableting moldability, with an appropriate hardness. In order to prepare a disintegrating tablet, it is preferable that the weight ratio of the sucrose fatty acid ester / the fatty acid salt having 16 to 22 carbon atoms = 80/20 to 20/80. If the sucrose fatty acid ester is 80% by weight or more, the fluidity of the powder at the time of tableting is reduced, and the raw material powder is not quickly filled in the mortar, so that tableting may not be performed smoothly. If the fatty acid salt having 16 to 22 carbon atoms is 80% by weight or more, the tablet may have low hardness and a low disintegration rate.
[0017]
The amount of the lubricant composition for tablets of the present invention is suitably 0.2 to 10% by weight, and 0.5 to 5.0% by weight based on the total amount of the tablet, from the viewpoint of tableting moldability. Is more preferable.
[0018]
Further, in the lubricant composition for tablets of the present invention, talc, glycerin fatty acid ester, polyglycerin fatty acid ester, hydrogenated oil, stearic acid, as a lubricating component, within a range that does not affect tablet moldability and tablet physical properties. , Aluminum stearate or the like may be added.
[0019]
The sucrose fatty acid ester having the above-described distribution of the degree of esterification is obtained by mixing a sucrose fatty acid ester having a low degree of esterification and a sucrose fatty acid ester having a high degree of esterification. A sucrose fatty acid ester having a low degree of esterification and a sucrose fatty acid ester having a high degree of esterification can be separately produced by a usual esterification reaction.
[0020]
【Example】
Using sucrose fatty acid esters A to E having a composition having a degree of esterification shown in Table 1, and magnesium stearate, lubricant compositions for tablets of Examples 1 to 3 and Comparative Examples 1 to 8 shown in Table 2 Was prepared. Also, Table 2 shows the fatty acids constituting each of the sucrose fatty acid esters A to E and magnesium stearate, and the composition of the degree of esterification determined from the composition in Table 1. The numerical values of Examples 1 to 3 and Comparative Examples 1 to 8 in Table 2 indicate the blending weight%.

Figure 2004155682
[0022]
[Table 2]
Figure 2004155682
[0023]
(Method of analyzing ester composition)
In the analysis of the degree of esterification of the sucrose fatty acid esters A to E shown in Table 1, after the sucrose fatty acid ester was fractionated from a monoester to an octaester by a liquid chromatography method, each fraction was subjected to an anthrone coloring method (J. Oleo). Sci., Vol.50, No.4 (2001)).
[0024]
(Analysis of fatty acid composition)
The analysis of the constituent fatty acids of the sucrose fatty acid ester shown in Table 1 was performed by gas chromatography using the resulting fatty acid as a methyl ester derivative by subjecting the sucrose fatty acid ester to alkaline hydrolysis.
[0025]
(Preparation of tablets)
Using the lubricant compositions for tablets of Examples 1 to 3 and Comparative Examples 1 to 8 shown in Table 2, compression molding was performed by a direct compression method using the formulation shown in Table 3, and tableting was performed. The tableting moldability, hardness, and disintegration time of the tablets were measured. The tableting conditions are as follows.
[0026]
(Tabletting conditions)
Tableting machine: HT-9 manufactured by Hata Iron Works
Tablet diameter: 8 mm in diameter.
[0027]
[Table 3]
Figure 2004155682
[0028]
Table 4 shows the results of evaluating the powder flowability before tableting, tableting moldability, tablet hardness, and tablet disintegration time for each example. The criteria for each evaluation are as follows.
[0029]
[Table 4]
Figure 2004155682
[0030]
(Powder fluidity before tableting)
The filling property of the raw material powder into the mortar was visually determined. The criterion is
:: Good fluidity of powder, excellent in filling into mortar,
Δ: The fluidity of the powder was slightly poor, and the filling into the mortar could not be performed smoothly.
×: Poor fluidity of powder and poor filling into mortar.
[0031]
(Tabletting moldability)
The shape of the tablet obtained by compression molding was visually judged. The criterion is
:: no capping, sticking, etc.
X: Capping, sticking, etc. occur.
[0032]
(Tablet hardness)
Tablet hardness was measured using a Monsanto hardness meter. The preferred hardness range of the tablet is 3-7 kg. If the hardness value is small, the tablet is easily broken during storage, and if the hardness value is large, the disintegration time in the disintegration test described later is prolonged.
[0033]
(Disintegration test)
The time until the tablet completely disintegrated in purified water was measured using a Japanese Pharmacopoeia disintegration test apparatus. A suitable range for the disintegration time is generally from 3 minutes to 10 minutes. If the disintegration time is long, for example, the tablet will not disintegrate in the stomach, resulting in poor absorption, and if the disintegration time is short, the tablet will be easily broken.
[0034]
From the above test results, it can be seen that those to which the lubricant compositions for tablets of Examples 1 to 3 are added have excellent powder flowability and tablet moldability. Further, it can be seen that the hardness of the obtained tablet is high and the disintegration time is short. On the other hand, those to which the lubricant compositions for tablets of Comparative Examples 4 to 6 were added had poor powder flowability, poor moldability, and often had poor tablet shapes. Was. In addition, the composition to which the lubricant composition for tablets of Comparative Example 7 was added had poor fluidity, and the tableting operation could not be performed smoothly. Furthermore, in the case where the lubricant composition for tablets of Comparative Example 8 was added, the fluidity of the powder and the moldability of the tablets were good, but the tablet hardness was low and the disintegration time of the tablets was long. .
[0035]
【The invention's effect】
The lubricant composition for tablets of the present invention contains, as a lubricating component, a stearate such as magnesium stearate or calcium stearate, and a sucrose fatty acid ester having a predetermined degree of esterification in a predetermined ratio.
