The present invention relates to a useful intraoral rapidly disintegrating pharmaceutical composition having hardness.

近年、高齢化社会への移行および生活環境の変化に伴い、老人や子供、水分摂取を制限されている患者に対し、取り扱い易くかつ服用しやすい医薬品製剤の開発が望まれている。また、水を用いずにそのまま服用できるような製剤は、場所を選ばずに服用できるため、急性疾患において症状が急に発現したときなどに有用である。このようなことから、口腔内に含んだ際に唾液のみ、もしくは少量の水で速やかに崩壊・溶解する口腔内速崩壊製剤の開発が進められてきている。   In recent years, with the shift to an aging society and changes in the living environment, it has been desired to develop pharmaceutical preparations that are easy to handle and take for the elderly, children, and patients whose water intake is restricted. In addition, since a preparation that can be taken as it is without using water can be taken at any place, it is useful when symptoms suddenly develop in an acute disease. For this reason, the development of a rapidly disintegrating preparation in the oral cavity that rapidly disintegrates and dissolves with only saliva or a small amount of water when contained in the oral cavity has been underway.

例えば、R.P.Scherer社から市販されている口腔内溶解型製剤Zydis速溶錠や、「口腔内崩壊製剤およびその製造法」(特許文献1参照)が挙げられる。これら文献においては、薬効成分を溶解あるいは懸濁した溶液を、予め成型したPTP(Press Through Package)シートのポケットに充填し、シートごと凍結乾燥または減圧乾燥することにより得られる口腔内速崩壊性製剤が記載されている。
また、「ポリビニルアルコールを配合した速崩壊性錠剤」(特許文献2参照)は、薬剤と糖類を混合し、ポリビニルアルコールを溶解した水または有機溶媒で練合後に、鋳型に充填し、フィルムを介して低圧で圧縮成型した後、乾燥することによって得られる口腔内速崩壊性製剤である。また、「口腔内溶解型圧縮成型物およびその製造法」(特許文献3参照)は、成形性の低い糖類に成形性の高い糖類で造粒し、乾燥後打錠して得られる口腔内溶解型圧縮成型物であり、さらに「口腔内速崩壊錠およびその製造法」(特許文献4参照)は、薬物、糖類に、非晶質化する糖を組み合わせて造粒し、圧縮処理後に加湿および乾燥することによって得られる口腔内速崩壊錠について開示している。
また、「速崩壊性固形製剤」(特許文献5参照)では、活性成分に平均粒子径が30μm〜300μmの糖または糖アルコール、崩壊剤、セルロース類を含有してなる速崩壊性固形製剤を開示している。
また、「口腔内速崩壊性医薬組成物およびその製造法」(特許文献6参照)は、高融点の糖アルコール類および/または糖類と、低融点の糖アルコール類および/または糖類とを組み合わせて混合処理、圧縮処理をした後、低融点の糖アルコール類/または糖類の融点温度付近で加熱して得られる口腔内速崩壊性医薬組成物について開示している。

For example, R.A. P. Examples include an orally-dissolving preparation Zydis fast-dissolving tablet commercially available from Scherer and “orally-disintegrating preparation and its production method” (see Patent Document 1). In these documents, a solution in which a medicinal component is dissolved or suspended is filled into a pocket of a pre-formed PTP (Press Through Package) sheet, and the oral rapidly disintegrating preparation obtained by freeze-drying or drying under reduced pressure together with the sheet Is described.
In addition, “a rapidly disintegrating tablet containing polyvinyl alcohol” (see Patent Document 2) is prepared by mixing a drug and a saccharide, kneading with water or an organic solvent in which polyvinyl alcohol is dissolved, filling the mold, and passing through a film. It is an intraoral quick disintegrating preparation obtained by compression molding at low pressure and drying. In addition, “oral dissolution type compression molded product and production method thereof” (see Patent Document 3) is obtained by granulating with high moldability saccharides into low moldability saccharides, and tableting after drying. In addition, the “orally-fast-disintegrating tablet and method for producing the same” (see Patent Document 4) is granulated by combining a drug, a saccharide and an amorphizing saccharide, and is humidified and compressed after the compression treatment. An intraoral quick disintegrating tablet obtained by drying is disclosed.

上述の口腔内速崩壊性製剤、例えば、口腔内溶解型製剤Zydis速溶錠は、優れた崩壊性を有するが、得られる錠剤の硬度が充分に高くなく、ワレやカケなどが生じやすいこと、または凍結乾燥や減圧乾燥が必要なため、生産コストが高くなりやすいという欠点があった。
また、特許第2807346号公報(特許文献1)記載の「口腔内崩壊製剤およびその製造法」あるいは国際公開第01/064190号パンフレット(特許文献2)に記載の「ポリビニルアルコールを配合した速崩壊性錠剤」は、製造過程において薬効成分の懸濁液もしくは乳濁液を用いるため、水に不安定な薬効成分を含有する医薬組成物に適応することが困難であることなどの欠点があった。
また、特開2001−58944号公報(特許文献5)に記載の「速崩壊性固形製剤」は、硬度および口腔内崩壊性において、本発明者らが後述する基準に達しているといえず、充分に優れているとは言えない。
さらに、国際公開第95/20380号パンフレット(特許文献3)に記載の「口腔内溶解型圧縮成型物およびその製造法」や国際公開第99/47124号パンフレット(特許文献4)に記載の「口腔内速崩壊錠およびその製造法」、さらに国際公開第2002/032403号パンフレット(特許文献6)に記載の「口腔内速崩壊性医薬組成物およびその製造法」は、優れた口腔内崩壊性および高い硬度を持つものの、製造工程が煩雑で工業的に適していないという欠点があった。
従って、本発明の課題は、優れた口腔内崩壊性と高い硬度を持ち、特に水に不安定な薬効成分にも適用できる口腔内速崩壊性医薬用組成物を、特殊な製剤技術を必要とすることなく、一般的な工業的製造方法で可能とする方法を提供することにある。
The above-mentioned intraoral rapidly disintegrating preparation, for example, orally dissolving preparation Zydis fast dissolving tablet, has excellent disintegration, but the hardness of the resulting tablet is not sufficiently high, and cracks and chips are likely to occur, or Since freeze-drying or reduced-pressure drying is required, there is a drawback that production cost tends to be high.
Further, “orally disintegrating preparation and production method thereof” described in Japanese Patent No. 2807346 (Patent Document 1) or “rapid disintegration compounded with polyvinyl alcohol” described in International Publication No. 01/064190 (Patent Document 2). Since “pills” use suspensions or emulsions of medicinal ingredients in the production process, they have drawbacks such as being difficult to apply to pharmaceutical compositions containing medicinal ingredients that are unstable in water.
In addition, the “rapidly disintegrating solid preparation” described in JP-A No. 2001-58944 (Patent Document 5) cannot be said to have reached the standard described later by the present inventors in terms of hardness and oral disintegration, It's not good enough.
Furthermore, “Oral Dissolution Type Compression Molded Product and Method for Producing the Same” described in WO95 / 20380 pamphlet (Patent Document 3) and “Oral cavity” described in WO99 / 47124 pamphlet (Patent Document 4). “Internally disintegrating tablet and method for producing the same”, and “Oral rapidly disintegrating pharmaceutical composition and method for producing the same” described in WO 2002/032403 pamphlet (Patent Document 6) Although it has high hardness, it has a drawback that the manufacturing process is complicated and not industrially suitable.
Therefore, the object of the present invention is to have a special preparation technique for an intraoral rapidly disintegrating pharmaceutical composition that has excellent oral disintegration property and high hardness and can be applied to a medicinal component that is particularly unstable to water. Therefore, it is intended to provide a method that can be realized by a general industrial manufacturing method.

本発明者らは鋭意研究の結果、乳糖と粉末セルロースを含有する医薬用組成物が、通常の輸送や使用に充分耐えうる高い硬度と優れた口腔内崩壊性を併せ持つことを見出した。
さらに、崩壊剤を加えることによって、より優れた口腔内崩壊性を有し、かつ高い硬度をもつ口腔内速崩壊性医薬用組成物が得られることを見出した。
さらに驚くべきことに、流動化剤や制酸剤として知られているメタケイ酸アルミン酸マグネシウム、およびメタケイ酸アルミン酸マグネシウム以外のケイ酸ならびにケイ酸塩から選ばれる1種または2種以上を、単独または組み合わせることにより、医薬用組成物の崩壊時間を延長せずに高い硬度を示すことをも見出し、本発明を完成させた。
As a result of intensive studies, the present inventors have found that a pharmaceutical composition containing lactose and powdered cellulose has both high hardness enough to withstand normal transportation and use and excellent oral disintegration.
Furthermore, it has been found that by adding a disintegrant, an intraorally rapidly disintegrating pharmaceutical composition having more excellent disintegration in the oral cavity and high hardness can be obtained.
Surprisingly, magnesium metasilicate aluminate known as a fluidizing agent or antacid, and one or more selected from silicic acid and silicate other than magnesium aluminate metasilicate are used alone. Alternatively, the present inventors have also found that, by combining them, high hardness is exhibited without extending the disintegration time of the pharmaceutical composition, and the present invention has been completed.

試験例4.1〜4.24にケイ酸カルシウムおよびメタケイ酸アルミン酸マグネシウムの添加における口腔内崩壊時間および硬度に及ぼす影響について打錠圧を変えて検討した。結果を表5に示す。ケイ酸カルシウムおよびメタケイ酸アルミン酸マグネシウムを無添加の群(以下、無添加群と称す)、ケイ酸カルシウムのみ添加した群(以下、ケイ酸カルシウム群と称す)、メタケイ酸アルミン酸マグネシウムのみ添加した群(以下、メタケイ酸アルミン酸マグネシウム群と称す)、ケイ酸カルシウムとメタケイ酸アルミン酸マグネシウムを共に添加した群(以下、併用群と称す)を各々硬度と口腔内崩壊時間についてグラフで表わした。上記4群を比較して、打錠圧を上昇させたときに、併用群は硬度の上昇に伴う口腔内崩壊時間の延長が最も起きにくく、優れた製剤特性を示した。   The effect of adding calcium silicate and magnesium aluminate metasilicate to Test Examples 4.1 to 4.24 on the oral disintegration time and hardness was examined by changing the tableting pressure. The results are shown in Table 5. A group to which calcium silicate and magnesium aluminate metasilicate were not added (hereinafter referred to as an additive-free group), a group to which only calcium silicate was added (hereinafter referred to as a calcium silicate group), and only magnesium aluminate metasilicate were added. A group (hereinafter referred to as a magnesium metasilicate aluminate group) and a group to which both calcium silicate and magnesium metasilicate aluminate were added (hereinafter referred to as a combination group) were represented by graphs with respect to hardness and oral disintegration time. When the tableting pressure was increased as compared with the above 4 groups, the combination group showed the most excellent formulation characteristics because the disintegration time in the oral cavity was hardly caused by the increase in hardness.

It was. Therefore, in the present invention, by adding both magnesium aluminate metasilicate and other silicic acid / silicate to lactose and powdered cellulose, a tablet having excellent oral disintegration property while maintaining high hardness can be obtained. I found out that
Furthermore, 10% ofloxacin was added as a medicinal ingredient, and the effect of tableting pressure on hardness and oral disintegration time was examined.
