造粒物:70〜100重量%、好ましくは80〜100%
添加剤:0〜30重量%、好ましくは0〜20%
造粒物調製の一般的手順
ザンチェッタ(Zanchetta)社製ロトグラニュレーター(ロトジュニア10型(Rotojunior 10 model)に、ガペンチンと、PEGと、場合により他の添加剤とから成る粉末の混合物を充填する。
上述の装置に充填可能な粉末の総量は0.8〜3kgであり、1〜2kg充填するのが好ましい。
次いで、ブレードスピードを100rpm、クラッシャースピードを1000rpmとして攪拌状態を維持し混合物を25℃に冷却する。
PEG:2〜25重量%
添加剤:0〜20重量%
総量:100%
実施例1に記載の手順により、次の組成の造粒物を調製した。
Gr1
ガバペンチン:90%
PEG6000:6%
