[態様7]
二段階の造粒法が、酸型カルボキシメチルセルロースからなる第一の崩壊剤成分、酸型カルボキシメチルセルロース以外の第二の崩壊剤成分、及び、賦形剤の三成分を含む崩壊性粒子組成物の製造方法であって、該三成分の中の任意の二成分を用いる第一湿式造粒工程、及び、第一湿式造粒工程で得られた造粒物と第一湿式造粒工程で用いられなかった残りの一成分を少なくとも用いる第二湿式造粒工程を含むことを特徴とする、態様1〜6のいずれか一項に記載の口腔内崩壊錠剤。
[態様8]

[態様9]
薬効成分がクロトリマゾール、イブブロフェン、エテンザミド、アセトアミノフェン、ファモチジン、アスコルビン酸、グリシン及びアスパラギン酸から成る群から選択される、態様1〜7のいずれかに記載の口腔内崩壊錠剤。
計算値としては、原則(1)で求めた値を採用し、薬効成分の構造がアミノ酸のように双性イオン状態を取る化学構造の場合には(2)で求めた値を採用した。
(1)CACheによるlogP計算値であり、以下に示す計算式を用いた。
LogP = Σniai
式中のniは、各原子団の数を表す。また、式中のaiは、各原子団の寄与率を示す。各原子団の寄与率の数値については、下記文献を参照。
(参照文献:Journal of Computational Chemistry, Vol. 9, No. 1, 80-90 (1988))
(2)KOWWINによるlogP計算値であり、以下に示す計算式を用いた。
log P = Σ fini + Σ cjnj + 0.229
式中のfiは各原子団の係数を表し、式中のniは各原子団の数を表す。また、式中のcjは各補正因子の係数を示し、式中のnjは各補正因子の数を示す。各原子団の係数及び各補正因子の係数の数値については、下記文献を参照。
(参照文献:Journal of Pharmacological Sciences 84, 83-92(1995))
つまり、分配係数が高い薬効成分は疎水性が高く、該薬効成分を含んだ口腔内崩壊錠は、錠剤内部まで水を導水することが困難であると推測されるため崩壊性を損なう恐れがある。また、分配係数が低い薬効成分は親水性が高く、水に容易に溶解する一方、打錠圧縮時に錠剤内部で薬効成分同士が結合性を高め、錠剤の成形性や崩壊性を低下させる可能性がある。
LogP =Log[( n-オクタノール相の薬効成分濃度)/ (水相の薬効成分濃度)]
尚、計算式と実測値との関係等を図1及び図2に示す。
尚、本願発明で使用される代表的な薬効成分に関して上記方法で計算した分配係数の計算値及び実験値を以下の表1に示した。
