【発明の属する技術分野】
本発明は、1)不快な味を有する塩基性医薬成分、2)糖類、3)ポリアニオン系ポリマー、4)矯味剤および5)カルボキシメチルセルロースを含有する固形製剤;およびその製造法に関する。
さらに、本発明は、口腔内の唾液の存在下、少量の水の存在下または胃内において速やかに崩壊する固形製剤、とりわけ口腔内崩壊性固形製剤として有用な速崩壊性固形製剤に関する。
【0002】
【従来の技術】
不快な味を有する塩基性医薬成分を含有する固形製剤において、不快な味の隠蔽方法は、例えば以下の文献に記載されている。
特表平2−502729には、「シメチジンと、顆粒化剤および風味マスキング剤としてポリヒドロキシ化合物のエステルと、所望により口に合う医薬上許容される乳化剤からなることを特徴とする医薬顆粒組成物」が記載されている。
特開平6−116138には、「(a)不快な味を呈する塩基性薬物と胃溶性高分子化合物を分散あるいは溶解させた低融点物質からなる複合体、(b)10重量%から70重量%の糖アルコールおよび(c)0.1重量%から7重量%の塩基性酸化物からなることを特徴とする経口製剤用組成物」が記載されている。
特開平10−236947には、「製剤バルクを製造する、次の工程:
(1)生理活性を有する薬剤、ポリエチレングリコールを含有する混合物を溶融造粒すること;
(2)該造粒した顆粒に、賦形剤を添加して、再び溶融造粒すること;から得られる粒状製剤」が記載されている。
特開平11−228450には、「不快な味を有する塩基性薬物およびアニオン性高分子物質を含有する不快な味を隠蔽した経口組成物」が記載されている。
一方、従来より、薬剤の嚥下が困難な患者、高齢者あるいは小児のために、服用しやすい剤形として、口腔内で迅速に崩壊・溶解する固形製剤の開発が進められている。
このような固形製剤は、例えば、以下の文献に記載されている。
特開平10−114655には、「治療上有効量の少なくとも一種の薬剤、少なくとも一種の中性あるいは塩基性の添加物、および崩壊剤を含有してなる固形製剤」が記載されている。
【0003】
【発明が解決しようとする課題】
上記公知文献に記載された固形製剤では、医薬成分の不快な味が十分に隠蔽されているとは言えず、また、該製剤の崩壊性および製剤強度も満足であるとは言えない。よって、不快な味を有する塩基性医薬成分(以下、単に塩基性医薬成分と略記することもある)の不快な味が十分に隠蔽され、かつ速やかな崩壊性、適度な製剤強度などの優れた特性を有する固形製剤の開発が望まれている。
また、上記公知文献に記載された固形製剤は、崩壊性および製剤強度の面で満足であるとは言えない。よって、速やかな崩壊性および適度な製剤強度を有する固形製剤の開発が望まれている。

Test example 1
The bitterness of the tablets obtained in the above-mentioned Examples and Comparative Examples was determined using the following test method. The results are shown in Table 1.
(1) Determination of bitterness
In three healthy adult males, the bitterness when the tablets were disintegrated in the oral cavity was determined according to the following criteria.
-: Almost no unpleasant taste or bitterness

++: Feels unpleasant taste or bitterness
As shown in Table 1, in the solid preparation of the present invention, the unpleasant taste of the basic pharmaceutical ingredient having an unpleasant taste was sufficiently concealed.
Test example 2
The tablet hardness and oral disintegration time of the tablets obtained in the above Examples and Comparative Examples were measured by the following test methods. The results are shown in Table 2.
(1) Hardness test
A tablet hardness tester (manufactured by Toyama Sangyo Co., Ltd.) was used. The results are shown as an average value of 5 tablets.
(2) Oral disintegration time
In three healthy adult boys, the time until the tablet completely disintegrated with only saliva in the oral cavity was measured.
As shown in Table 2, the solid preparation and the rapidly disintegrating solid preparation of the present invention have a rapid disintegrating property and an appropriate preparation strength (tablet hardness).
