Description
本発明は、錠剤に関し、より詳細には、形状に特徴を有する錠剤に関する。 The present invention relates to a tablet, and more particularly to a tablet having a shape characteristic.
錠剤は、医薬品の中で最も多用されている剤形で、大部分は内用で用いられている。錠剤には、2種類以上の薬を層状にした二層錠や三層錠といった多層錠、内核と外層を有する有核錠など、様々な剤形がある。多層錠の製造においては、層間の剥離が起こるという問題が起こりうる。これに対しては、比表面積が大きい乳糖を結合剤として配合する方法(特許文献1:特開平5-163138)、特定の嵩比重を有する結晶セルロースを配合する方法(特許文献2:特開2003-144528)、互いに接する層を形成する粉粒体の平均粒子径を特定の比率にする方法(特許文献3:特開2000-336027)、特定の物性を有する低置換度ヒドロキシプロピルセルロースを用いる方法(特許文献4:特開2008-280251)などの解決法が提案されている。 Tablets are the most frequently used dosage form of pharmaceuticals, and most are used internally. Tablets have various dosage forms such as a multilayer tablet such as a two-layer tablet or a three-layer tablet in which two or more kinds of drugs are layered, and a dry-coated tablet having an inner core and an outer layer. In the production of multilayer tablets, the problem of delamination can occur. For this, a method of blending lactose having a large specific surface area as a binder (Patent Document 1: Japanese Patent Laid-Open No. 5-163138), a method of blending crystalline cellulose having a specific bulk specific gravity (Patent Document 2: Japanese Patent Laid-Open No. 2003). -144528), a method in which the average particle size of the granular material forming the layers in contact with each other is a specific ratio (Patent Document 3: JP 2000-336027 A), a method using a low-substituted hydroxypropyl cellulose having specific physical properties A solution such as (Patent Document 4: JP-A-2008-280251) has been proposed.
錠剤、カプセル剤、顆粒剤などの固形製剤に含まれる主薬がその製剤の周囲の媒液に溶け出す時間を測定することは、溶出試験と呼ばれており、日本薬局方で規定されている試験法の一つである。本試験法は、製剤設計・品質の管理手段として利用されており、例えば、内用固形製剤に溶出規格を設定することにより、医薬品の溶出性に関する品質の確保が図られている。従って、錠剤をはじめとする内用固形製剤の製造・販売にあたっては、溶出の規格値を満たす必要がある。固形製剤の溶出性を改善する方法としては、製剤に含まれる2つの有効成分を製剤中に分離して配合することが提案されている(特許文献5:特表2008-543729)。 Measuring the time it takes for the active ingredient contained in a solid preparation such as a tablet, capsule or granule to dissolve in the medium surrounding the preparation is called a dissolution test, and is a test prescribed by the Japanese Pharmacopoeia One of the laws. This test method is used as a formulation design / quality control means. For example, by setting an elution standard for a solid preparation for internal use, quality relating to the dissolution property of a drug is ensured. Therefore, in the manufacture and sale of internal solid preparations such as tablets, it is necessary to satisfy the dissolution standard value. As a method for improving the dissolution property of a solid preparation, it has been proposed to separate and mix two active ingredients contained in the preparation (Patent Document 5: Special Table 2008-543729).
また、錠剤にコーティングが施されることがあるが、これは、医薬品の主成分の不快な臭いや味のマスクキング、色の隠蔽、素錠に含まれる主成分の酸化や加水分解による変質の防止、腸溶性や持続性の賦与などを目的としている。錠剤のコーティングの一つとして、酸化チタンを配合したフィルム層によるコーティングがあるが、酸化チタンは非常に硬いため、コーティング中にコーティングパンの内壁と擦れて錠剤が黒変してしまい、商品価値を失うという問題があった。これに対しては、フィルム層にタルクを特定の割合で配合することにより錠剤の黒変を防止するという提案がなされている(特許文献6:特開2000-44464)。 In addition, tablets may be coated. This is due to masking of unpleasant odors and tastes of the main ingredients of pharmaceuticals, hiding of colors, oxidation and hydrolysis of the main ingredients contained in uncoated tablets. Its purpose is prevention, entericity and sustainability. As one of the tablet coatings, there is a coating with a film layer containing titanium oxide, but because titanium oxide is very hard, it rubs against the inner wall of the coating pan during coating, and the tablet turns black, increasing the commercial value. There was a problem of losing. For this, a proposal has been made to prevent blackening of tablets by blending talc in a film layer at a specific ratio (Patent Document 6: Japanese Patent Laid-Open No. 2000-44464).
このように、錠剤製造における打錠障害、主薬の溶出性の問題、外観不良といった問題の各々については、解決策の提案がなされているが、これらの3つの問題を同時に解決できる方法は知られていない。 As described above, solutions have been proposed for each of the problems such as tableting troubles in tablet production, problems of dissolution of the active ingredient, and poor appearance, but methods that can solve these three problems at the same time are known. Not.
本発明は、打錠障害が抑制され、主薬の溶出性が良好で、外観不良が抑制された錠剤を提供することを目的とする。 An object of the present invention is to provide a tablet in which the tableting trouble is suppressed, the dissolution of the active ingredient is good, and the appearance defect is suppressed.
また、本発明は、錠剤の打錠障害抑制、主薬の溶出性改善及び/又は外観不良抑制のための方法を提供することを目的とする。 Another object of the present invention is to provide a method for suppressing tableting troubles, improving dissolution of the active ingredient and / or suppressing appearance defects.
本発明者は、上記の課題を解決すべく鋭意研究を行った結果、錠剤の短径R2/Cup depth又は平均R2/Cup depthを特定の範囲に制御することにより、錠剤の打錠障害抑制、主薬の溶出性改善及び外観不良抑制に効果があることを見出し、本発明を完成させるに至った。本発明の要旨は以下の通りである。 As a result of diligent research to solve the above problems, the present inventor has controlled tablet tableting troubles by controlling the short diameter R2 / Cup depth or the average R2 / Cup depth of the tablets to a specific range, The present inventors have found that it is effective in improving the dissolution of the active ingredient and suppressing the appearance defect, thereby completing the present invention.

摩損度の測定方法
摩損度とは、錠剤の衝撃に対する脆さや削れやすさを数量的に表現した物性値である。測定方法は、まず錠剤10錠を精密に量り(この重量をW0とした)、錠剤をガラス筒(全長33.6cm、外径3.5cm、内径2.65cm)に充填する。ガラス筒の全長の中央位置に金属製ふるい(直径4cm、サイズ5.5メッシュ、線径0.5インチ)を有するガラス筒を錠剤摩損度試験機(林間工業)に取り付け、振動幅12.2cmの上下運動を、1分間あたり250往復の条件にて、2分間作動させる。動作終了後,ガラス筒から錠剤を取り出し,ふるいで軽く揺すり,粉および錠剤の破片を除いたのち,ふるい上の錠剤総質量 を精密に量った(この重量をWとした)。また,キャッピングおよび破損を起こした錠剤があれば,その数を明記した。摩損度は、計算式:摩損度(%)=(W0−W)÷W0×100で求めた。
Method of measuring friability The friability is a physical property value that quantitatively expresses the brittleness and ease of scraping of tablets. First, 10 tablets are precisely weighed (this weight is designated as W0), and the tablets are filled into a glass tube (total length 33.6 cm, outer diameter 3.5 cm, inner diameter 2.65 cm). Attach a glass cylinder with a metal sieve (diameter 4 cm, size 5.5 mesh, wire diameter 0.5 inch) at the center of the total length of the glass cylinder to the tablet friability tester (Rinkan Kogyo), and move up and down with a vibration width of 12.2 cm. Operate for 2 minutes at 250 reciprocations per minute. After the operation was completed, the tablet was taken out from the glass tube, shaken lightly with a sieve, and after removing powder and tablet fragments, the total mass of the tablet on the sieve was precisely measured (this weight was defined as W). In addition, the number of capped and damaged tablets was specified. The friability was determined by the formula: friability (%) = (W0−W) ÷ W0 × 100.
