Abstract
Description
本発明は、（１）糖類および糖アルコール類から選ばれる物質、（２）崩壊剤ならびに（３）イグラチモドを含有することを特徴とする速崩壊性錠剤に関する。 The present invention relates to a rapidly disintegrating tablet comprising (1) a substance selected from sugars and sugar alcohols, (2) a disintegrant and (3) iguratimod.
これまでに、服用しやすい薬剤形として、口腔内で迅速に崩壊する速崩壊性錠剤の開発が進められている。薬剤を速崩壊性錠剤とすることで、様々なメリットが生まれる。たとえば、嚥下困難な患者、高齢者および小児にとって、速崩壊性錠剤は、容易にかつ安全に服用することができる錠剤である。睡眠導入剤では、横になったままリラックスした状態で、服用することができ、降圧剤では、急に血圧が上がって気分が悪くなった際、すぐに何処でも服用できる（非特許文献１）。 So far, fast-disintegrating tablets that rapidly disintegrate in the oral cavity have been developed as drug forms that are easy to take. Various merit is born by making a medicine into a fast disintegrating tablet. For example, for patients with difficulty swallowing, the elderly and children, fast disintegrating tablets are tablets that can be easily and safely taken. With a sleep-inducing agent, it can be taken in a relaxed state while lying down, and with an antihypertensive agent, when blood pressure suddenly rises and makes you feel sick (Non-Patent Document 1) .
このような速崩壊性錠剤の製造法としては、薬物および糖類を寒天水溶液に懸濁し、予め成型されたＰＴＰ（Press Through Package）のポケットに充填し、ゼリー状に固化させた後、乾燥することにより錠剤を得る製造法が知られている（特許文献１）。しかし、この方法では、特殊な製造設備が必要であり、得られる錠剤の硬度は十分なものではなかった。また、薬物、水溶性結合剤および水溶性賦形剤を含む混合物を低圧力で打錠後、加湿し、乾燥させる方法が知られている（特許文献２）。しかし、この方法は、特殊な製造設備が必要であり、製造工程が煩雑になるなどの欠点があった。
一方、崩壊性に優れるが成形性の低い糖類または糖アルコール類を崩壊性に劣るが成形性の高い糖類または糖アルコール類を用いて造粒後、この造粒物を通常の打錠機で圧縮成形して速崩壊性錠剤を製造する方法が知られている（特許文献３）。しかし、この方法により得られる錠剤の硬度は、通常の経口用医薬錠剤よりも小さく、錠剤硬度をさらに高めることが望まれている。
As a method for producing such a fast disintegrating tablet, a drug and a saccharide are suspended in an agar aqueous solution, filled in a pre-formed PTP (Press Through Package) pocket, solidified in a jelly shape, and then dried. The manufacturing method which obtains a tablet by this is known (patent document 1). However, this method requires special production equipment, and the hardness of the resulting tablet is not sufficient. In addition, a method is known in which a mixture containing a drug, a water-soluble binder, and a water-soluble excipient is tableted at low pressure, and then humidified and dried (Patent Document 2). However, this method has the disadvantages that a special manufacturing facility is required and the manufacturing process becomes complicated.
On the other hand, after granulating saccharides or sugar alcohols with excellent disintegrability but poor moldability but with poor disintegrability but with high moldability, this granulated product is compressed with a normal tablet press. A method for producing a rapidly disintegrating tablet by molding is known (Patent Document 3). However, the hardness of the tablet obtained by this method is smaller than that of a normal oral pharmaceutical tablet, and it is desired to further increase the tablet hardness.
速崩壊性錠剤は、通常の錠剤と異なり、錠剤のサイズを大きくしても服用性が損なわれることがない。錠剤を意図的に大きくすることで、服用性ならびに、たとえばＰＴＰ包装からの取り出し易さおよび錠剤の摘み易さといった取扱性を同時に改善することができる（非特許文献２）。たとえば、関節リウマチ患者に投与される抗関節リウマチ剤および消炎鎮痛剤などは、速崩壊性錠剤のサイズを大きくすることで、優れた服用性を維持しながら、取扱性を改善し、指先が不自由な患者の服薬コンプライアンスを格段に向上させる。 Unlike a normal tablet, a rapidly disintegrating tablet does not impair the ingestibility even if the tablet size is increased. By intentionally increasing the size of the tablet, it is possible to simultaneously improve the ingestibility and handling properties such as ease of taking out from the PTP package and ease of picking the tablet (Non-patent Document 2). For example, anti-rheumatoid arthritis drugs and anti-inflammatory analgesics administered to patients with rheumatoid arthritis increase the size of fast-disintegrating tablets, improving the handleability and improving the fingertips. Significantly improve compliance of free patients.
通常、錠剤の服用性を向上させるためには、速やかな崩壊性が必要である。一方、錠剤には、製造から服用までの間に壊れない程度の硬度が必要である。しかしながら、崩壊性および硬度は、通常相反する。そのため、速やかな崩壊性と取り扱いに十分な硬度を同時に満たす錠剤を通常の製造法で製造することは、困難である。 Usually, rapid disintegration is necessary to improve the dosage of tablets. On the other hand, tablets need to have a hardness that does not break between manufacture and administration. However, disintegration and hardness are usually in conflict. For this reason, it is difficult to produce a tablet that simultaneously satisfies rapid disintegration and hardness sufficient for handling by a normal production method.
イグラチモド（Ｎ−（７−（（メタンスルホニル）アミノ）−４−オキソ−６−フェノキシ−４Ｈ−１−ベンゾピラン−３−イル）ホルムアミド）は、抗リウマチ剤として開発されている薬剤である（特許文献４）。これまで、イグラチモドの速崩壊性錠剤は、知られていない。
口腔内の唾液または少量の水の存在下において、速やかに崩壊する優れた服用性を有し、かつ取り扱いに十分な硬度を有し、さらに、通常の製造設備で製造できるイグラチモドを含有する速崩壊性錠剤が強く望まれている。 Fast disintegration containing iguratimod, which has excellent dosing properties that disintegrate rapidly in the presence of saliva or a small amount of water in the oral cavity, has sufficient hardness for handling, and can be manufactured with ordinary manufacturing equipment Sex tablets are highly desired.
このような状況下において、本発明者らは、関節リウマチ患者に投与される抗リウマチ作用を有する化合物または消炎鎮痛作用を有する化合物を含有する速崩壊性錠剤について鋭意検討した結果、驚くべきことに、糖類および糖アルコール類から選ばれる物質ならびに崩壊剤に抗リウマチ剤であるイグラチモドを組み合わせることにより、活性成分であるイグラチモドが高い成形性向上能力を発揮し、イグラチモドを含まない錠剤に比べて速やかな崩壊性を保つにもかかわらず、硬度が飛躍的に高まることを見出した。さらに、通常の製造設備で、優れた速崩壊性錠剤が製造できることを見出し、本発明を完成した。 Under such circumstances, the present inventors have surprisingly studied as a result of diligent research on a fast disintegrating tablet containing a compound having an anti-rheumatic action or an anti-inflammatory analgesic action administered to a patient with rheumatoid arthritis. By combining igratetimo, an anti-rheumatic agent, with a substance selected from saccharides and sugar alcohols and a disintegrant, the active ingredient iguratimod exhibits a high moldability-improving ability and is quicker than tablets containing no iguratimod. It has been found that the hardness increases dramatically despite maintaining disintegration. Furthermore, the present invention was completed by finding that an excellent quick disintegrating tablet can be produced with ordinary production equipment.
本発明で得られる（１）糖類および糖アルコール類から選ばれる物質、（２）崩壊剤ならびに（３）イグラチモドを含有することを特徴とする速崩壊性錠剤は、通常の製造法で製造でき、しかも取り扱いに十分耐える非常に高い硬度を有する。また、本発明の錠剤は、大きな錠剤に成形しても口腔内で速やかに崩壊し、患者の取扱性および服用性に優れている。本発明の速崩壊性錠剤は、手指の動きが不自由なリウマチ患者、薬剤の嚥下が困難な患者、高齢者および小児にとって、取扱性および服用性を同時に満たす錠剤である。
本発明の錠剤は、一般に用いられる製造設備を用いて製造することができ、特別な工程が不要である。さらに、本発明の錠剤は、長期間の保存、安定性にも優れている。またイグラチモドは、口腔内で苦味などの不快な味を示さず、たとえば、苦味マスキングのためにイグラチモドにコーティングを施すといった必要もない。
A rapidly disintegrating tablet characterized by containing (1) a substance selected from saccharides and sugar alcohols obtained in the present invention, (2) a disintegrant and (3) iguratimod can be produced by an ordinary production method, Moreover, it has a very high hardness enough to withstand handling. Moreover, the tablet of this invention disintegrates rapidly in the oral cavity even if it is formed into a large tablet, and is excellent in patient handling and administration. The rapidly disintegrating tablet of the present invention is a tablet that simultaneously satisfies handling and administration for rheumatic patients who have difficulty in hand movement, patients who have difficulty swallowing drugs, elderly people and children.
The tablet of this invention can be manufactured using the manufacturing equipment generally used, and a special process is unnecessary. Furthermore, the tablet of the present invention is excellent in long-term storage and stability. Also, iguratimod does not show an unpleasant taste such as bitterness in the oral cavity, and it is not necessary to coat iguratimod for bitterness masking, for example.
