- Orally disintegrating tablets have been developed as a convenient form that can be safely taken by patients, elderly people, children, etc. who have difficulty swallowing drugs, and can be taken easily without water.
- Orally disintegrating tablets have sufficient breaking strength (tablet hardness) that does not cause tablet chipping and powdering during tablet production or during transportation or opening, as in the case of ordinary tablets, and quickly in the oral cavity. It is important to have an excellent disintegration property (disintegration time) that disintegrates rapidly.
- the moldability is the relationship between the tableting compression force and the tablet hardness obtained for this. Production methods that require high tableting compression force may cause problems such as restrictions on the performance of the tableting device, reduced productivity, and reduced function of the coating fine particles contained in the tablet. It is also important that the composition has excellent formability, i.e., the ability to obtain a higher tablet hardness with the same tablet compression force or to achieve the same tablet hardness with a lower tablet compression force. .
- tablet hardness and disintegration are properties that are opposite to each other.

- the disintegrating particle composition of Example 1 is mixed with the medicinal ingredients of Table 2 and 0.5 parts by weight of magnesium stearate, and shown in Table 2 using a simple tableting machine (HANDTAB-100, Ichihashi Seiki Co., Ltd.). Tableting was performed with tableting compression force to obtain a tablet having a diameter of 8.0 mm, a corner flat tablet, and a weight of 250 mg.
- Hardness Hardness (N) was measured using a digital Kiya-type hardness meter (Fujiwara Manufacturing Co., Ltd.).
- Disintegration time in water The disintegration time in water was measured using a disintegration tester (NT-400, Toyama Sangyo Co., Ltd.) according to the method described in the Japanese Pharmacopoeia (but without an auxiliary board). The hardness and disintegration time were each measured 6 times, and the average value thereof was taken as the measurement result.
- the present invention greatly contributes to research and development of orally disintegrating tablets having excellent tablet hardness and disintegration.

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)]
