Abstract
Description
本発明は、主剤を含有する被覆微粒子からなり、良好な口腔内崩壊性と錠剤強度を有する口腔内崩壊錠およびその製造方法に関する。 The present invention relates to an orally disintegrating tablet comprising coated fine particles containing a main agent and having good orally disintegrating properties and tablet strength, and a method for producing the orally disintegrating tablet.
近年、高齢化社会の到来や患者のコンプライアンス向上のため、水なしでも服用可能な口腔内崩壊錠の意義が重要視されるようになってきており、実際、種々の製剤が臨床応用されつつある。その大半は、薬物が胃内に直ちに放出されるように製剤設計されたものであるが、胃酸により分解される薬物の保護や、薬物の持続放出を目的として、腸溶性もしくは徐放性皮膜を施した粒子を含有する口腔内崩壊錠も開発されている。
しかしながら、徐放性もしくは腸溶性皮膜を施した粒子を含む口腔内崩壊錠は、低圧で打錠せざるを得ないことが多いが、そうすると、錠剤強度が不十分となり、輸送時や薬局など実用上の取り扱いが困難になりがちであった。
そこで、被覆微粒子を含む口腔内崩壊錠に関して、例えば以下のような技術が文献上提案されている。
In recent years, the significance of orally disintegrating tablets that can be taken without water has become important for the arrival of an aging society and the improvement of patient compliance. In fact, various preparations are being clinically applied. . Most of the drugs are designed so that the drug is released immediately into the stomach, but enteric or sustained-release coatings are used for the purpose of protecting the drug decomposed by gastric acid and the sustained release of the drug. Orally disintegrating tablets containing the applied particles have also been developed.
However, orally disintegrating tablets containing particles with sustained-release or enteric coatings often have to be tableted at low pressure, but in this case, the tablet strength becomes insufficient, and it is practically used for transportation and pharmacies. The above handling tended to be difficult.
Thus, for example, the following techniques have been proposed in the literature regarding orally disintegrating tablets containing coated fine particles.
特許文献１には、室温を超える温度に加温して打錠することにより、被覆膜の破壊を低減する方法が開示されているが、打錠機にヒーターなど特別な装置を取り付けることを要するものである。 Patent Document 1 discloses a method of reducing breakage of the coating film by heating and tableting at a temperature exceeding room temperature, but it is necessary to attach a special device such as a heater to the tableting machine. It is necessary.
特許文献２には、塩酸タムスロシンの腸溶性徐放性微粒子を含有する口腔内崩壊錠の製造方法が開示されているが、弱圧で打錠した後、加温及び加湿し、乾燥させる工程が必須であり、操作が煩雑である。 Patent Document 2 discloses a method for producing an orally disintegrating tablet containing enteric sustained-release fine particles of tamsulosin hydrochloride. However, there is a step of heating and humidifying after tableting under low pressure and drying. It is essential and the operation is complicated.
非特許文献１には、被覆微粒子の耐胃液性を担保すべく、わざわざ７層にまで渡ってコーティングした製剤が開示されている。 Non-Patent Document 1 discloses a preparation that is purposely coated over 7 layers in order to ensure the gastric juice resistance of the coated fine particles.
これらの技術を応用した製剤は既に市販されているが、いずれも錠剤の硬度が比較的低く、取り扱い上注意が必要であった。 Formulations applying these techniques are already on the market, but all of them have relatively low tablet hardness, and need attention in handling.
また、口腔内崩壊錠に良好な崩壊性と十分な強度を持たせるために種々の検討がなされているが、特に近年ではケイ酸化合物などの無機化合物を使用した以下のような技術が文献上提案されている。 In addition, various studies have been made to give the orally disintegrating tablet good disintegration and sufficient strength. In recent years, however, the following techniques using inorganic compounds such as silicic acid compounds have been published in the literature. Proposed.
特許文献３には、無機化合物と糖類を均一に分散させた懸濁液を噴霧乾燥することにより得られる医薬組成物を圧縮成型することにより、硬度を上昇させた口腔内崩壊錠が開示されているが、この技術は噴霧乾燥用の特殊な機器及び設備や技術を必要とするものである。 Patent Document 3 discloses an orally disintegrating tablet having increased hardness by compression molding a pharmaceutical composition obtained by spray drying a suspension in which an inorganic compound and a saccharide are uniformly dispersed. However, this technique requires special equipment, equipment and technology for spray drying.
特許文献４には、錠剤の担体として糖類をメタケイ酸アルミン酸塩でコーティングした組成物を使用することにより、携帯に必要な硬度を保つ方法が開示されているが、このように無機物でコーティングされた糖類は味や口当たりが悪く、また製造工程も煩雑である。 Patent Document 4 discloses a method of maintaining hardness required for carrying by using a composition in which a saccharide is coated with metasilicate aluminate as a carrier for tablets, and is thus coated with an inorganic substance. Saccharide has a bad taste and mouthfeel, and the production process is complicated.
特許文献５には、実質的に活性成分、結晶セルロース及び無機賦形剤からなる粉末を直接圧縮形成することにより、硬度を確保する口腔内速崩壊錠が開示されているが、水に不溶性の賦形剤が製剤の大半を占めることになるため、水溶性の糖類や糖アルコール等を含む口腔内崩壊錠に味や口当たりの点で勝るとは考えにくい。 Patent Document 5 discloses an intraoral rapidly disintegrating tablet that ensures hardness by directly compressing and forming a powder consisting essentially of an active ingredient, crystalline cellulose and an inorganic excipient, but is insoluble in water. Since the excipient occupies the majority of the preparation, it is unlikely that it will be superior to the orally disintegrating tablet containing water-soluble saccharides and sugar alcohols in terms of taste and mouthfeel.
特許文献６には、乳糖および粉末セルロースを含有する医薬用組成物にメタケイ酸アルミン酸マグネシウムを添加することを特徴とする錠剤の硬度増強方法が開示されているが、高速撹拌造粒機を用いて混合粉末を複数段階に渡って造粒するため、製造工程で被覆微粒子が破壊される可能性が高い。 Patent Document 6 discloses a method for enhancing the hardness of a tablet, characterized by adding magnesium aluminate metasilicate to a pharmaceutical composition containing lactose and powdered cellulose. Since the mixed powder is granulated in a plurality of stages, it is highly possible that the coated fine particles are destroyed in the manufacturing process.
したがって、実用上十分な強度を有し、製造方法が簡易である被覆微粒子含有口腔内崩壊錠は従来の技術では、知られていなかった。 Therefore, a coated fine particle-containing orally disintegrating tablet that has practically sufficient strength and a simple production method has not been known in the prior art.
本発明は、良好な錠剤強度及び口腔内崩壊性を有する、被覆微粒子含有口腔内崩壊錠を提供することを目的とする。 An object of the present invention is to provide an orally disintegrating tablet containing coated fine particles having good tablet strength and orally disintegrating property.
本発明者らは、上記課題を解決するために鋭意検討を行った結果、驚くべきことに、主剤を含有する被覆微粒子を適当な添加剤とともに造粒して得られる組成物にメタケイ酸アルミン酸マグネシウム粉末を添加した後打錠することによって口腔内崩壊時間に影響を与えることなく良好な錠剤強度が得られることを発見し、本願発明を完成するに至った。 As a result of intensive studies to solve the above-mentioned problems, the present inventors have surprisingly found that a composition obtained by granulating coated fine particles containing the main agent together with appropriate additives into metasilicate aluminate. It was discovered that by tableting after adding magnesium powder, good tablet strength can be obtained without affecting the disintegration time in the oral cavity, and the present invention has been completed.

比較例１
メタケイ酸アルミン酸マグネシウムの代わりに、Ｄ−マンニトールを３０重量部添加した以外は実施例１と同様の操作で錠剤を得た。
Comparative Example 1
A tablet was obtained in the same manner as in Example 1 except that 30 parts by weight of D-mannitol was added instead of magnesium aluminate metasilicate.
（試験例１）
実施例１、比較例１により得られた錠剤について、口腔内崩壊時間、引っ張り強度について確認した。引っ張り強度は、シュロイニゲル硬度計（Ｄｒ．Ｓｃｈｌｅｕｉｎｉｇｅｒ Ｐｈａｒｍａｔｒｏｎ ＡＧ）により求めた破断面積荷重から、下式にて算出した。
引っ張り強度（Ｎ／ｃｍ２）＝２×破断荷重（Ｎ）／（π×錠剤直径（ｃｍ）×錠剤厚み（ｃｍ））
その結果を以下の表１に示す。
(Test Example 1)
The tablets obtained in Example 1 and Comparative Example 1 were confirmed for oral disintegration time and tensile strength. The tensile strength was calculated by the following equation from the fracture area load determined by a Schleuniger hardness tester (Dr. Schleininger Pharmatron AG).
Tensile strength (N / cm 2) = 2 × breaking load (N) / (π × tablet diameter (cm) × tablet thickness (cm))
The results are shown in Table 1 below.
以上の結果より、実施例１の錠剤は、口腔内崩壊時間を延長させることなく硬度及び引っ張り強度が上昇することが判明した。同じく打錠圧を４９００Ｎ、８８２０Ｎとした場合においても同様の結果が得られた。 From the above results, it was found that the tablet of Example 1 increased in hardness and tensile strength without extending the oral disintegration time. Similarly, similar results were obtained when the tableting pressure was 4900N and 8820N.
（試験例２）
実施例１、比較例１と同様の操作で得た錠剤について、摩損度（％）を確認した。その結果を以下の表２に示す。摩損度の測定は第十五改正日本薬局方の錠剤の摩損度試験法に基づいたが、より過酷な状況を想定し、ドラム回転数の条件を１２５、２５０、５００回転で比較した。
(Test Example 2)
The degree of friability (%) was confirmed for the tablets obtained in the same manner as in Example 1 and Comparative Example 1. The results are shown in Table 2 below. The measurement of friability was based on the 15th revised Japanese Pharmacopoeia tablet friability test method, but the conditions of drum rotation speed were compared at 125, 250, and 500 rotations assuming a more severe situation.
以上の結果より、実施例１の錠剤は、メタケイ酸アルミン酸マグネシウム粉末の添加により摩損度についても著しく改善されることが判明した。 From the above results, it was found that the tablet of Example 1 was remarkably improved in terms of friability by adding magnesium aluminate metasilicate powder.
