【発明の属する技術分野】
本発明は、H2受容体拮抗剤に、甘味剤としてステビア抽出物を配合してなる経口製剤に関する。
【0002】
【従来の技術】
現在、薬剤を用いた十二指腸潰瘍や吻合部潰瘍の治療には、H2受容体拮抗剤やプロトンポンプ阻害剤が第1選択薬として使用されている。また、胃潰瘍治療においても、強力な胃酸分泌抑制作用を有するH2受容体拮抗剤やプロトンポンプ阻害剤と種々の粘膜防御因子増強剤等の服用が中心であり、高い治癒率が得られるようになってきた。特に、ファモチジン、ラニチジン又はシメチジン等のH2受容体拮抗剤は、最近では、医療用医薬品としてだけではなく一般薬として薬局店頭においても販売されるようなってきている。
しかしながら、これらのH2受容体拮抗剤は、わずかに苦味や特異な味等の不快な味を有する為、内服時の口腔内における服用感は、良好ではなかった。薬剤に由来する不快な味は、通常、製剤中への甘味剤の添加やフィルムコーティングや糖衣コーティング等の皮膜の被覆を施すことにより、ある程度のマスクは可能である。しかしながら、皮膜の被覆を施すことは口腔内での製剤の崩壊遅延をもたらす為、特に、高齢者にとっても服用が容易な口腔内で迅速に崩壊する口腔内速崩壊性錠剤を調製する場合には難しい。
【0003】
【発明が解決しようとする課題】
したがって、H2受容体拮抗剤を含有する服用感に優れる製剤、即ち、H2受容体拮抗剤由来のわずかな苦味や特異な味等の不快な味をマスクし、味を改善できる経口製剤の開発が、非常に待ち望まれている。
特に、高齢者にとって服用が容易であり、嚥下能力のある成人においても水なしでも服用できるH2受容体拮抗剤を含有する口腔内速崩壊性錠剤の開発において、口腔内で不快な味を感じることなく、しかも安定性に優れる速崩壊性錠剤が待望されている。
以上のような状況に鑑み、本発明者らは、H2受容体拮抗剤を含有してなる不快な味を改善した経口製剤並びにその製造法を探索すべく鋭意研究を行った。その結果、以下に示す構成により所期の目的を達成できることを見いだし、本発明を完成した。
