経口懸濁剤500mLあたりとして:
175mLの精製水に、2.500gの安息香酸ナトリウムを完全に溶解するまで攪拌しながらゆっくりと添加した。この溶液を、連続的に攪拌しながら約60℃に加熱し、300.000gのショ糖を添加した。ゆっくりと連続して攪拌しながら、次にこの溶液を約30℃に冷却し、以下の材料を高速分散しながらゆっくりと添加した。

ヒドロキシエチルセルロース 2.500g
イチゴフレーバー 0.500g
経口懸濁剤2500Lあたりとして
約315Lの精製水に、約67%で溶液中にあるショ糖1500kgを攪拌しながら添加した。連続的に攪拌しながら、完全に溶解/分散するまで投入する。
− 安息香酸ナトリウム 7.50kg

ラセカドトリルを、水に再懸濁した散剤の形態および実施例1の水性懸濁剤の形態で24匹のマウス(値あたりn=4)へ経口投与した(48mg/kg)。ラセカドトリル(DT326)の有効成分の血漿中濃度を測定する。図1に結果を示す。この結果は、水性懸濁剤で投与された場合のラセカドトリルのバイオアベイラビリティが、水に再懸濁した散剤の形態で投与した場合のものと比較して50%増加することを示す。
実施例1の懸濁剤(10mgラセカドトリル/2.5mL)および実施例2の懸濁剤(10mgラセカドトリル/1mgオンダンセトロン/2.5ml)のpHを4、4.5および5に調整した。各懸濁剤に対するこの3つの試料を、次の促進条件下、40℃/75%の相対湿度で6週間貯蔵した。
実施例2bで得られた懸濁剤中のラセカドトリルの粒子サイズ分布プロファイルを、レーザー回折測定を用いて決定し、上限が約750μmであり、1μmから約70μmの範囲内の粒子が容積で50%に相当する2モード分布が示される。このプロファイルは、懸濁剤が(小さな粒子による)バイオアベイラビリティの改善、および(大きな粒子による)安定性の改善の両方を示すという点で有利である。
