ヒスタミンH3拮抗薬の評価
医薬組成物の調製
0.01〜50w/w%の式(I)の活性成分、15〜50w/w%のラクトース、15〜50w/w%のジャガイモでんぷん、5〜15w/w%のポリビニルピロリドン、1〜5w/w%のタルク、0.01〜3w/w%のステアリン酸マグネシウム、1〜3w/w%のコロイド状二酸化ケイ素および2〜7w/w%のウルトラアミロペクチンを混合し、次いで湿式造粒法で造粒し、圧縮し、錠剤化した。
上述の方法に従って作製した錠剤を、腸溶性の又は胃溶解(gastrosolvent)フィルム、または糖類およびタルクからなる層によって被覆した。これらの糖衣錠は、蜜蝋およびカルナバワックスの混合物によって研磨した。
0.01〜50w/w%の式(I)の活性成分、1〜5w/w%のラウリル硫酸ナトリウム、15〜50w/w%のでんぷん、15〜50w/w%のラクトース、1〜3w/w%のコロイド状二酸化ケイ素および0.01〜3w/w%のステアリン酸マグネシウムを十分に混合し、その混合物を篩に通し、そして硬質ゼラチンカプセルに充填した。
成分:0.01〜15w/w%の式(I)の活性成分、0.1〜2w/w%の水酸化ナトリウム、0.1〜3w/w%のクエン酸、0.05〜0.2w/w%のニパギン(4−ヒドロキシ安息香酸メチルナトリウム)、0.0052〜0.02w/w%のニパゾール、0.01〜0.5w/w%のカルボポール(ポリアクリル酸)、0.1〜5w/w%の96%エタノール、0.1〜1w/w%の香料、20〜70w/w%のソルビトール(70%水溶液)および30〜50w/w%の蒸留水。
各座薬用に、0.01〜15w/w%の式(I)の活性成分および1〜20w/w%のラクトースを完全に混合し、次いで50〜95w/w%の脂肪(adeps pro)座薬(例えばWitepsol 4)を融解し、35℃に冷却し、活性成分とラクトースとの混合物をホモジナイザーでその中で混合した。得られた混合物を冷却型中で成形した。
注射用途として、マンニトールまたはラクトースの5%溶液を、再蒸留水で作製し、そして該溶液を、滅菌溶液となるように濾過した。注射用途として、式(I)の活性成分の0.01〜5%溶液もまた、再蒸留水で作製し、そしてこの溶液を、濾過して滅菌溶液にした。これらの2つの溶液を無菌条件下で混合し、アンプル中に1mlずつ充填し、アンプルの内容物を凍結乾燥し、そしてアンプルを窒素下で密封した。投与前に、アンプル内容物を滅菌水または0.9%(生理的)滅菌塩化ナトリウム水溶液に溶解した。
ヒスタミンH3拮抗薬とアセチルコリンエステラーゼ阻害剤との同時投与の評価
H3拮抗薬で処理した場合、MPFCおよびHCの両方において、細胞外HAレベルの明確な増加がみられる一方で、ACh放出は、わずかな上昇しか生じなかった。その一方で、両領域における、AChの細胞外レベルの明確な増加が、アセチルコリンエステラーゼ阻害剤の後に実証された。この結果は、アセチルコリンエステラーゼ阻害剤(AChEIs)に関する公開されたデータと良く一致している(CerbaiらによるEur.J.Pharmacol.(2007)572:142−150;ScaliらによるJ Neural Transm.(2002)109(7−8):1067−80;KosasaらによるJpn.J.Pharmacol.(1999)81:216−222)。
