Description

本発明は、通常の設備で優れた口腔内速崩錠を製造する方法に関する。さらに詳しくは、糖類から成る粒子を核として、ここに水溶性高分子および/または水に不溶な高分子を含む溶液または分散液を用い、さらに、予め無水ケイ酸を添加・混合して得られた改質難溶性薬物を製剤原料として用い、この改質難溶性薬物または、改質難溶性薬物を含む粉体で粉末コーティングした粒子を含有する口腔内速崩錠の製造方法に関するものである。   The present invention relates to a method for producing an excellent intraoral quick-disintegrating tablet with ordinary equipment. More specifically, it is obtained by using a solution or dispersion containing a water-soluble polymer and / or a water-insoluble polymer as a core, and further adding and mixing silicic anhydride in advance. The present invention relates to a method for producing an intraoral rapidly disintegrating tablet containing particles that are powder-coated with a modified poorly soluble drug or a powder containing the modified poorly soluble drug.

口腔内崩壊型製剤は、杉原らによる「厚生省厚生科学研究シルバーサイエンス研究」および英国R.P.SchererのZYDIS製剤の紹介が端緒となり、研究開発が盛んになった「すぐに役立つ粒子設計・加工技術(じほう)221頁、2003年」。   Orally disintegrating preparations are described in “Silver Science Research, Ministry of Health and Welfare Science” by Sugihara et al. P. The introduction of Scherer's ZYDIS formulation was the beginning, and research and development became active. “Immediately useful particle design and processing technology (Jiho) 221 pages, 2003”.

そして、近年、通常の経口剤を服用することが困難な高齢者及び小児などの患者が容易に服用できる剤形として、口腔内で速やかに溶解或いは崩壊する錠剤についての研究が盛んに行われており、商品化されたものも多くみられる「Pharm.Tech.Japan,第14巻、第11号、111頁、1998年」。   In recent years, active research has been conducted on tablets that dissolve or disintegrate rapidly in the oral cavity as dosage forms that can be easily taken by patients such as the elderly and children who are difficult to take ordinary oral preparations. There are also many commercialized products “Pharm.Tech.Japan, Vol. 14, No. 11, p. 111, 1998”.

公知のように、口腔内崩壊型錠の製造方法は、3つに大別される。第一は、鋳型製剤である。これは薬物を分散あるいは溶解した液を予め成形されたPTPシールなどのポケットに充填し、凍結乾燥後シールを施す方法であり、第二は、湿製錠で、薬物を含む湿潤粉体を極めて低い圧力で成形し、乾燥して、強度のある錠剤とする方法である。第三の方法は、一般錠剤型製剤である。これは多孔質成形体製剤、易成形性添加剤使用製剤および崩壊機構工夫製剤に分けることができる。多孔質成形体製剤は、薬物、糖類等の混合造粒物を低圧で成形後、加湿乾燥処理、加熱処理等により錠剤強度の向上を図るものである。
易成形性添加物使用製剤は、結晶セルロース等の易成形性添加物、糖類等添加物の微細化等により成形性の向上を図るものである。
また、崩壊機構工夫製剤は、超崩壊剤の利用、滑沢剤微量化(外部滑沢)、酸塩基反応による発泡作用利用により崩壊性の向上を図るものである「すぐに役立つ粒子設計・加工 技術(じほう)221頁、2003年及びPharm.Tech.Japan,第14巻、第11号、111頁、1998年」。
As is well known, methods for producing orally disintegrating tablets are roughly divided into three. The first is a template formulation. This is a method in which a drug-dispersed or dissolved solution is filled in a pre-formed pocket such as a PTP seal and sealed after freeze-drying. This is a method in which the tablet is molded at a low pressure and dried to form a strong tablet. The third method is a general tablet type formulation. This can be divided into a porous molded body preparation, a preparation using an easily moldable additive and a preparation for disintegration mechanism. The porous molded body preparation is intended to improve tablet strength by molding a mixed granulated product such as drug and saccharide at low pressure, and then humidifying and drying, heating, and the like.
The preparation using an easily moldable additive is intended to improve moldability by miniaturizing an easily moldable additive such as crystalline cellulose and an additive such as sugar.
In addition, the disintegration mechanism devised formulation is intended to improve disintegration by using a super disintegrant, reducing the amount of lubricant (external lubricant), and using foaming action by acid-base reaction. Technology (Jiho), p.221, 2003 and Pharm.Tech.Japan, Vol. 14, No. 11, p.111, 1998 ”.

特許文献1には、薬物として、アニセラセムを用い、表面張力低下能を有する水溶性高分子を含有した口腔内速崩錠が開示されている。   Patent Document 1 discloses an intraoral quick-disintegrating tablet using aniseracem as a drug and containing a water-soluble polymer having a surface tension reducing ability.

この特許文献1においては、口腔内の付着やぬめり感のない製剤を提供することを目的に、一般に結合剤として用いられているポリビニルピロリドンおよび表面張力低下能を有する水溶性高分子にヒドロキシプロピルメチルセルロース等が併用して使われおり、また、界面活性剤スルホコハク酸ジオクチルナトリウムも配合されている。試験例中には崩壊の様子は観察しているが、崩壊時間につていの記載はない。水溶性高分子を合わせて2.5〜3.0重量%用いていることから崩壊性の影響、さらに緩下作用をもつ界面活性剤が0.04重量%含有されていることから健康面への影響が懸念される。   In Patent Document 1, for the purpose of providing a preparation having no stickiness or sliminess in the oral cavity, polyvinylpyrrolidone generally used as a binder and a water-soluble polymer having a surface tension reducing ability are used as hydroxypropylmethylcellulose. Etc. are also used in combination, and the surfactant dioctyl sodium sulfosuccinate is also blended. In the test examples, the state of disintegration is observed, but there is no description of the disintegration time. The combined use of water-soluble polymers in the range of 2.5 to 3.0% by weight results in a disintegrating effect, and the presence of 0.04% by weight of a surfactant that has a laxative action helps improve health. Is concerned about the impact of

特許文献2には、ビタミンKを吸着した結晶セルロースを溶媒により造粒し、乾燥させて、ここに糖類を加え、結合剤を含む水溶液を添加し、混練合し、湿式打錠する製剤法が開示されている。   Patent Document 2 discloses a formulation method in which crystalline cellulose adsorbed with vitamin K is granulated with a solvent, dried, a saccharide is added thereto, an aqueous solution containing a binder is added, kneaded and mixed, and wet tableting is performed. It is disclosed.

しかしながら、この製剤法は、湿式打錠法を用いて錠剤としているので、通常の設備ではなく、特別な製剤化装置を必要とする。   However, since this preparation method is a tablet using the wet tableting method, a special preparation device is required instead of a normal equipment.

また、特許文献3には、薬物が実質上水に不溶性で無機賦形薬、崩壊剤、水溶性賦形薬、結晶セルロースからなる錠剤が開示されている。   Patent Document 3 discloses a tablet in which the drug is substantially insoluble in water and is composed of an inorganic excipient, a disintegrant, a water-soluble excipient, and crystalline cellulose.

しかしながら、この特許文献3に記載のものは、水に不溶な無機賦形薬を含むことから口腔内でのざらつき等の服用感の点で、問題である。

本発明が解決しようとする問題点は、従来から存する通常の設備ではなく、特別な製造設備でないと優れた有用性を有する口腔内速崩錠を製造できないという点である。   The problem to be solved by the present invention is that an intraoral quick-disintegrating tablet having excellent utility cannot be produced unless it is a special production facility, not a conventional facility existing in the past.

従って、本発明の目的は、特別新規な製造設備を要することなく、従来から存する公知の通常の製造設備により、優れた崩壊性と通常の取り扱いにおいて十分な硬度と耐摩損性を有し、かつ服用感の良い口腔内速崩錠を製造できる方法を提供することにある。   Therefore, the object of the present invention is to provide excellent disintegration, sufficient hardness and wear resistance in ordinary handling by a conventional production facility that has been conventionally known, without requiring special new production facilities, and An object of the present invention is to provide a method capable of producing an intraoral rapidly disintegrating tablet having a good feeling of administration.

本発明者らは、親水性の薬物アスコルビン酸を用いた口腔内速崩錠の製造方法について、既に取得した特許第3884056号(特願2006−018342)で開示している。この特許に係る製剤技術により、水に溶けにくい難溶性薬物エテンザミドを用いて、口腔内速崩錠を製造したところ、従来の製造法(湿式打錠法)と比較して、崩壊性の優位性は確認できなかった。   The present inventors have disclosed a method for producing an intraoral quick-disintegrating tablet using the hydrophilic drug ascorbic acid in Japanese Patent No. 3884056 (Japanese Patent Application No. 2006-018342) already obtained. By using the pharmaceutical technology related to this patent, an orally fast-disintegrating tablet was produced using a sparingly soluble drug etenzamide, which is difficult to dissolve in water. The superior disintegration advantage compared to the conventional manufacturing method (wet tableting method) Could not be confirmed.

そこで、難溶性薬物エテンザミドの口腔内速崩錠の製造について、改めて検討した。   Therefore, the production of an orally rapidly disintegrating tablet of the poorly soluble drug etenzamide was examined again.

予め、エテンザミドに無水ケイ酸を添加・混合し、エテンザミドの粉末物性を改善した。これを改質エテンザミドとする。この改質エテンザミドを用いて、口腔内速崩錠を製造した。   In advance, silicic anhydride was added to and mixed with etenzamide to improve the powder physical properties of etenzamide. This is referred to as modified etenzamid. An intraoral rapidly disintegrating tablet was produced using this modified etenzamid.

先ず、結晶乳糖を核として、ポリビニルピロリドンK−30のエタノール溶液を添加し、次いで、そこに改質エテンザミドを散布して粒子核を粉末コーティングし、この粉末コーティングの操作を繰り返した後、乾燥・整粒して粉末コーティング粒子とした。   First, using crystalline lactose as a core, an ethanol solution of polyvinylpyrrolidone K-30 is added, and then the modified ethenzamide is sprayed thereon to powder-coat the particle core. After repeating this powder coating operation, drying and drying are performed. The particles were sized to obtain powder-coated particles.

次いで、この粉末コーティングした粒子に、造粒乳糖、コリドン−CLおよびマルチトールを配合し、均一に混合する。さらにステアリン酸マグネシウムを添加し、二次混合する。この混合粉末を直径8mm、1錠200mgとして、ロータリー打錠機で打錠して錠剤とした。   The powder coated particles are then blended with granulated lactose, Kollidon-CL and maltitol and mixed uniformly. Further, magnesium stearate is added and secondarily mixed. This mixed powder was 8 mm in diameter and 200 mg in 1 tablet, and tableted by a rotary tableting machine to give tablets.

しかしながら、未改質エテンザミドで製造したときと同様に、従来の製造法(湿式打錠法)と比較して、崩壊性の優位性は確認できなかった。   However, as in the case of production with unmodified ethenzamid, the superiority of disintegration could not be confirmed as compared with the conventional production method (wet tableting method).

次に、ポリビニルピロリドンK−30のエタノール溶液の替わりにポリビニルピロリドンK−30の水エタノール混合溶液を用いて、同様にして、改質エテンザミドを含有した口腔内速崩錠を製造したところ、偶然にも従来の製造法(湿式打錠法)と比較して、飛躍的に優れた崩壊性をもつ口腔内速崩錠を製造できることが確認できた。   Next, using a mixed solution of polyvinyl pyrrolidone K-30 in water ethanol instead of an ethanol solution of polyvinyl pyrrolidone K-30, an intraoral quick-disintegrating tablet containing modified ethenzamide was produced in the same manner. In addition, it was confirmed that an intraoral quick-disintegrating tablet having dramatically superior disintegration property can be produced as compared with the conventional manufacturing method (wet tableting method).

また、エテンザミドは経時的に錠剤表面にウイスカーが発生することが知られているが、本発明により製造した口腔内速崩錠では、経時的にウイスカーの発生はみられなかった。   In addition, whilst it is known that etenzamide generates whiskers on the tablet surface over time, whisker generation was not observed over time in the intraoral rapidly disintegrating tablets produced according to the present invention.

表1の結果から、比較例1のエテンザミドでは、30メッシュおよび50メッシュの篩を通過しない粉末の割合が大きい。エテンザミドが凝集していると思われる。   From the results in Table 1, in the etenzamide of Comparative Example 1, the proportion of powder that does not pass through the 30 mesh and 50 mesh sieves is large. It seems that etenzamide is aggregated.

一方、軽質無水ケイ酸を添加した検討例1および検討例2では、30メッシュおよび50メッシュの篩を通過しない粉の割合は、極めて少なくなり、検討例1では、140メッシュの篩を通過しない粉の割合が70%を占めている。また、検討例2は、200メッシュの篩を通過した粉末の割合が35%であり、エテンザミドの凝集は改善したものと思われる。   On the other hand, in Study Example 1 and Study Example 2 in which light anhydrous silicic acid was added, the proportion of powder that did not pass through the 30-mesh and 50-mesh screens was extremely small. In Study Example 1, powder that did not pass through the 140-mesh screen. The ratio accounts for 70%. In Study Example 2, the proportion of the powder that passed through the 200-mesh sieve was 35%, and it was considered that the aggregation of etezamide was improved.

以上の検討結果から、軽質無水ケイ酸の添加量0.5%を最適添加量とした。   From the above examination results, the addition amount of light silicic acid 0.5% was determined as the optimum addition amount.

次に、結合液組成によるエテンザミド粉末コーティング粒子の粒度分布について説明する。結晶乳糖10gに、ポリビニルピロリドン(PVP)K−30(固形分0.045g)の結合液を添加する。ここに、予めエテンザミド9.5gに軽質無水ケイ酸を0.5g添加し、混合した改質エテンザミドを加える。この操作を10回繰り返し、粉末コーティングした後、乾燥・整粒し、コーティング粒子とした。それぞれの結合液組成で製したコーティング粒子について、その粒度分布を30〜200メッシュの篩を用いて測定した。その結果を表2に示す。   Next, the particle size distribution of the etenzamide powder coating particles according to the binding liquid composition will be described. A binding solution of polyvinylpyrrolidone (PVP) K-30 (solid content 0.045 g) is added to 10 g of crystalline lactose. Here, 0.5 g of light anhydrous silicic acid is added to 9.5 g of ethenamide in advance, and the mixed modified etenzaamide is added. This operation was repeated 10 times, and after powder coating, drying and sizing were performed to obtain coated particles. About the coating particle made with each binding liquid composition, the particle size distribution was measured using a 30-200 mesh sieve. The results are shown in Table 2.

表2中の検討例3は、結合液組成が、エタノール:水=75:25であり、検討例4は、結合液組成が、エタノール:水=50:50であり、検討例5は、結合液組成が、エタノール:水=25:75であり、比較例2は、エタノール100%である。   In Examination Example 3 in Table 2, the composition of the binding solution is ethanol: water = 75: 25, Examination Example 4 is that the composition of the binding solution is ethanol: water = 50: 50, and Examination Example 5 is the binding. The liquid composition is ethanol: water = 25: 75, and Comparative Example 2 is ethanol 100%.

Figure 2008189634
Figure 2008189634

表2の結果から、比較例2の結合液組成が、エタノール100%では、200メッシュの篩を通過した粉末の割合が50%程度を占めている。これは、エテンザミドがエタノールに溶解することから、エテンザミドは粉末コーティングされることなく、エタノールにより溶解し、エテンザミド同士で凝集した為と思われる。   From the results in Table 2, when the composition of the binding solution of Comparative Example 2 is 100% ethanol, the proportion of the powder that has passed through the 200-mesh sieve accounts for about 50%. This is probably because ethenzamide is dissolved in ethanol, and thus ethenzamide is dissolved by ethanol without being powder-coated and aggregated with ethenzamide.

一方、結合液組成に水を含有した検討例3〜5では、200メッシュの篩を通過した粉末の割合が比較例2の結合液組成エタノール100%に比べて大きく減少している。   On the other hand, in Examination Examples 3 to 5 containing water in the binding liquid composition, the ratio of the powder that passed through the 200 mesh sieve was greatly reduced as compared with 100% of the binding liquid composition ethanol in Comparative Example 2.

従って、結晶乳糖にエテンザミドが粉末コーティングされていると思われる。検討例4の結合液組成がエタノール:水=50:50では、200メッシュの篩を通過した粉末の割合が10%以下である。   Therefore, it seems that ethenamide is powder-coated on crystalline lactose. When the composition of the binding solution in Study Example 4 is ethanol: water = 50: 50, the ratio of the powder that has passed through the 200 mesh sieve is 10% or less.

以上の検討結果から、結合液組成がエタノール:水=50:50を最適結合組成とした。   From the above examination results, the binding solution composition was ethanol: water = 50: 50 as the optimum binding composition.

次に、以下の表3に示す原料成分を用いた本発明の口腔内速崩錠の製造方法の実施例について説明する。   Next, the Example of the manufacturing method of the intraoral quick-disintegrating tablet of this invention using the raw material component shown in the following Table 3 is demonstrated.

試験例1
実施例1〜実施例5で得られた内部滑沢打錠法による錠剤と、実施例6〜実施例10で得られた外部滑沢打錠法による錠剤のそれぞれについて、その物性を測定した。その結果を表4に示す。
Test example 1
The physical properties of each of the tablets obtained by Examples 1 to 5 by the internal lubricant tableting method and the tablets obtained by Examples 6 to 10 by the external lubricant tableting method were measured. The results are shown in Table 4.

Figure 2008189634
Figure 2008189634

表4の結果から、実施例6〜実施例10の外部滑沢打錠法では、日局崩壊度に関して、実施例1〜実施例5の内部滑沢打錠法に比べ錠剤は速やかに崩壊した。また、打錠圧0.3ton以上では錠剤の日局崩壊度が10秒以内で、錠剤の硬度が約30N以上、摩損度が0.5%以下であった。よって、外部滑沢打錠法は口腔内速崩錠の製造方法として優れた方法である。   From the results in Table 4, in the external lubricant tableting method of Example 6 to Example 10, the tablet disintegrated more quickly than the internal lubricant tableting method of Example 1 to Example 5 with respect to the disintegration degree of JP. . When the tableting pressure was 0.3 ton or higher, the tablet disintegration degree was within 10 seconds, the tablet hardness was about 30 N or more, and the friability was 0.5% or less. Therefore, the external lubricant tableting method is an excellent method for producing an intraoral quick disintegrating tablet.

試験例2
実施例3および比較例3で得られた錠剤の崩壊度等の物性について測定した。
Test example 2
The physical properties such as the disintegration degree of the tablets obtained in Example 3 and Comparative Example 3 were measured.

なお、錠剤の崩壊度は、日本薬局方記載崩壊試験法に従い、水を試験液として行い、6錠の平均値を算出した。口腔内崩壊時間は健常人4人で各錠剤について、3回の試験結果の平均値を算出した。錠剤硬度は、錠剤硬度計(エルベッカ社製 TBH200)を用い、各錠剤10錠の平均値を算出した。また、錠剤摩損度は、日本薬局方記載錠剤摩損度試験器(富山産業社製 TFT120)を用い、1分間25回転で4分間回転し、摩損度を測定した。その結果を表5に示す。   In addition, according to the disintegration test method described in the Japanese Pharmacopoeia, the disintegration degree of the tablets was measured using water as a test solution, and the average value of 6 tablets was calculated. Oral disintegration time was calculated by calculating the average value of the test results of three times for each tablet by 4 healthy subjects. For the tablet hardness, a tablet hardness meter (TBH200 manufactured by Elbeca) was used to calculate the average value of 10 tablets. The tablet friability was measured by using a tablet friability tester (TFT120 manufactured by Toyama Sangyo Co., Ltd.) described in the Japanese Pharmacopoeia, rotating for 4 minutes at 25 rpm for 1 minute. The results are shown in Table 5.

Figure 2008189634
Figure 2008189634

表5の結果から、従来の湿式打錠法(比較例3)では、日局崩壊度が本発明の製造方法(実施例3)の6倍であった。また、口腔内崩壊時間は湿式打錠法(比較例3)が本発明の製造方法(実施例3)の5倍の時間を要した。   From the results of Table 5, in the conventional wet tableting method (Comparative Example 3), the JP disintegration degree was 6 times that of the production method of the present invention (Example 3). In addition, the oral disintegration time required 5 times as long as the wet tableting method (Comparative Example 3) of the production method of the present invention (Example 3).

従って、本発明の製造方法により得られた口腔内速崩錠は、日局崩壊度が10秒以内で、錠剤の硬度が30N以上、摩損度が0.5%以下であり、従来の湿式打錠法に比べて優れた方法である。   Therefore, the intraoral quick-disintegrating tablet obtained by the production method of the present invention has a disintegration degree of 10 seconds or less, a tablet hardness of 30 N or more and a friability of 0.5% or less, and the conventional wet compression. This method is superior to the tablet method.

次に、本発明に係る製造方法により得られた口腔内速崩錠のウイスカーの観察について説明する。   Next, observation of the whisker of the intraoral quick-disintegrating tablet obtained by the production method according to the present invention will be described.
