Description

【0001】
【技術分野】
本発明は、小型化により服用を容易にしたクラリスロマイシン錠剤に関する。
【0002】
【背景技術】
一般に医薬品の錠剤は、原薬に賦形剤および他の補助成分を加え、造粒した後滑沢剤を加えて打錠することによって製造される。しかし1回の投与量が多い薬物の場合は、錠剤に製剤加工するための賦形剤および補助成分の量も薬物量に比例して多くなり、錠剤の重量、従ってその寸法が増し、その服用を困難にする。特開2002−173428にはクロリスロマイシン錠剤において賦形剤を使用しないかその配合量を減らして錠剤を小型化する技術が記載されている。
【0003】
クラリスロマイシンの場合、1回あたりの標準的投与量は200mgである。慣用の製剤技術によって製造したクラリスロマイシン錠剤は、1錠中クラリスロマイシン200mgを含有し、素錠の状態で少なくとも全重量320mg,直径10mm,厚み5mmの寸法を有し、むしろ服用困難な大型の錠剤になる。従って原薬の含量はそのままとし、全体の重量および寸法を小型化することによって服用を容易にすることが望まれる。
【0004】
【発明の開示】
本発明は、小型化したクラリスロマイシン錠剤を提供する。この錠剤はクラリスロマイシンと、崩壊剤と、結合剤と、任意に賦形剤を含み、崩壊剤はクロスポビドンであり、結合剤はポビドン、ポリビニルアルコールまたはコポリビドンから選ばれ、素錠の状態で錠剤中のクラリスロマイシンの重量は75%以上である。
【0005】
【発明を実施するための最良の形態】
本発明においては、錠剤の崩壊剤としてクロスポビドンを使用し、結合剤としてポビドン、ポリビニルアルコールまたはコポリビドンを使用する。ポリビニルアルコールが好ましい。本発明ではこれらの崩壊剤および結合剤を使用することにより、錠剤に通常含まれている乳糖のような賦形剤を省くかまたはその量を低減することができる。使用する場合、賦形剤は慣用のものでよいが、リン酸水素カルシウムのようなかさ密度の大きい賦形剤が好ましい。アミノアルキルメタクリレートコポリマー(オイドラギッドRS)のような徐放性コーティングポリマーを慣用の賦形剤に代えて用いてもよい。
【0006】
錠剤は、主薬、クロスポビドンおよび任意の賦形剤を混合し、混合物を結合剤の水溶液で練合して造粒し、乾燥、整粒し、造粒物にステアリン酸マグネシウムのような滑沢剤を加えて打錠することによって製造することができる。結合剤を造粒前の粉末混合物へ加え、水で練合して造粒することも可能である。また崩壊剤および使用する場合賦形剤の一部は、滑沢剤と共に打錠前の顆粒へ加えることもできる。この場合顆粒の流動性を改善するため軽質無水ケイ酸を混合してもよい。
【0007】
このようにして得られる素錠(裸錠)の総重量の75%以上をクラリスロマイシンが占めるので、残余の崩壊剤等の成分の総重量は素錠重量の25%をこえない。しかしながらクラリスロマイシンのみでは錠剤に圧縮成形することができないので、素錠重量に対するクラリスロマイシンの割合は85%が限度であろう。そのため素錠中の結合剤の重量は1ないし7%特に2ないし5%、およびクロスポビドンの重量は5ないし20%特に7ないし15%が適当である。
【0008】
素錠はクラリスロマイシンの苦味をマスクし、さらに服用を容易にするためフィルムコーティングすることができる。コーティング材料は例えば水溶性のポリマーであり、コーティング量は素錠重量の5%以下であることが好ましい。
【0009】
本発明によれば、1錠中クラリスロマイシン含量200mgの錠剤の場合、素錠の状態で重量260mg以下、直径8.5の錠剤を提供することができ、これをフィルムコートした市販品の重量337mg,直径10.2mmと比較すると有意に小型化されている。

【Technical field】
The present invention relates to a clarithromycin tablet that is easily taken by downsizing.
[0002]
[Background]
In general, pharmaceutical tablets are produced by adding excipients and other auxiliary ingredients to the drug substance, granulating, and then tableting with a lubricant. However, in the case of a drug with a large single dose, the amount of excipients and auxiliary ingredients for processing into a tablet increases in proportion to the drug amount, and the weight of the tablet, and thus its size, increases. Make it difficult. Japanese Patent Application Laid-Open No. 2002-173428 describes a technique for reducing the size of tablets by not using excipients or reducing the amount of chlorithromycin tablets.
[0003]
In the case of clarithromycin, the standard dose per dose is 200 mg. A clarithromycin tablet produced by a conventional formulation technique contains 200 mg of clarithromycin in one tablet, has a size of at least a total weight of 320 mg, a diameter of 10 mm, and a thickness of 5 mm in the form of an uncoated tablet. Become a pill. Therefore, it is desirable to keep the content of the drug substance as it is and to make it easy to take by reducing the overall weight and size.
[0004]
DISCLOSURE OF THE INVENTION
The present invention provides miniaturized clarithromycin tablets. This tablet contains clarithromycin, a disintegrant, a binder, and optionally an excipient, the disintegrant is crospovidone, and the binder is selected from povidone, polyvinyl alcohol or copolyvidone and in an uncoated form The weight of clarithromycin in the tablet is 75% or more.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
In the present invention, crospovidone is used as a disintegrant for tablets, and povidone, polyvinyl alcohol or copolyvidone is used as a binder. Polyvinyl alcohol is preferred. In the present invention, by using these disintegrants and binders, an excipient such as lactose usually contained in tablets can be omitted or the amount thereof can be reduced. When used, the excipient may be conventional, but an excipient with a high bulk density such as calcium hydrogen phosphate is preferred. Sustained release coating polymers such as aminoalkyl methacrylate copolymers (Eudragid RS) may be used in place of conventional excipients.
[0006]
Tablets are prepared by mixing the active ingredient, crospovidone and any excipients, kneading the mixture with an aqueous solution of a binder, granulating it, drying and sizing the granulated product, such as magnesium stearate. It can be produced by adding an agent and tableting. It is also possible to granulate by adding a binder to the powder mixture before granulation and kneading with water. Moreover, a disintegrating agent and a part of excipient | filler, when used can also be added to the granule before tableting with a lubricant. In this case, light anhydrous silicic acid may be mixed to improve the fluidity of the granules.
[0007]
Since clarithromycin accounts for 75% or more of the total weight of the uncoated tablets (bare tablets) thus obtained, the total weight of the components such as the remaining disintegrant does not exceed 25% of the uncoated tablet weight. However, since clarithromycin alone cannot be compressed into tablets, the ratio of clarithromycin to uncoated tablet weight would be limited to 85%. Therefore, the weight of the binder in the uncoated tablet is 1 to 7%, particularly 2 to 5%, and the weight of crospovidone is 5 to 20%, particularly 7 to 15%.
[0008]
The uncoated tablet masks the bitter taste of clarithromycin and can be film-coated to facilitate administration. The coating material is, for example, a water-soluble polymer, and the coating amount is preferably 5% or less of the uncoated tablet weight.
[0009]
According to the present invention, in the case of a tablet having a clarithromycin content of 200 mg in one tablet, it is possible to provide a tablet having a weight of 260 mg or less and a diameter of 8.5 in the form of an uncoated tablet. Compared to 337 mg and a diameter of 10.2 mm, the size is significantly reduced.
[0010]
Example 1
200 parts by weight of clarithromycin, 11.2 parts by weight of crospovidone, and 8 parts by weight of povidone were put into a high speed mixer and mixed. An appropriate amount of water was added to this and kneaded. After wet sizing, drying and dry sizing, 11.2 parts by weight of crospovidone, 4.8 parts by weight of light anhydrous silicic acid, and 4.8 parts by weight of magnesium stearate are mixed, and the mixture is compressed at a tableting pressure of 800 kg. Tableting was performed to obtain tablets with a tablet diameter of 8.5 mm and a weight of 240 mg.
[0011]
Example 2
200 parts by weight of clarithromycin, 7.6 parts by weight of lactose and 9.6 parts by weight of crospovidone were put into a high speed mixer and mixed. 6 parts by weight of partially saponified polyvinyl alcohol was dissolved in an appropriate amount of water and kneaded. Then, after wet sizing, drying and dry sizing, 9.6 parts by weight of crospovidone, 2.4 parts by weight of light anhydrous silicic acid, and 4.8 parts by weight of magnesium stearate were mixed, and the mixture was compressed at a tableting pressure of 800 kg. Tableting was performed to obtain tablets with a tablet diameter of 8.5 mm and a weight of 240 mg.
[0012]
Example 3
204 parts by weight of clarithromycin, 12.5 parts by weight of calcium hydrogen phosphate, and 10 parts by weight of crospovidone were put into a high speed mixer and mixed. 6 parts by weight of partially saponified polyvinyl alcohol was dissolved in an appropriate amount of water and kneaded. Then, after wet sizing, drying and dry sizing, 10 parts by weight of crospovidone, 2.5 parts by weight of light anhydrous silicic acid and 5 parts by weight of magnesium stearate are mixed, and the mixture is tableted at a tableting pressure of 800 kg. A tablet with a tablet diameter of 8.5 mm and a weight of 250 mg was obtained.
[0013]
Example 4
200 parts by weight of clarithromycin, 20 parts by weight of Eudragit RS, and 10 parts by weight of crospovidone were charged into a high speed mixer. 10 parts by weight of copolypydone was dissolved in an appropriate amount of water and kneaded. Thereafter, after wet sizing, drying and dry sizing, 2.5 parts by weight of light anhydrous silicic acid and 5 parts by weight of magnesium stearate were mixed, and the mixture was tableted with a tableting pressure of 800 kg, and the tablet diameter was 8.5 mm. A tablet weighing 247.5 mg was obtained.
[0014]
The weight, diameter, and thickness of the examples and commercially available clarithromycin tablets were measured. However, although the commercial product is a film-coated tablet, the measurement was performed in a film-coated state. The results are shown in Table 1.
