実施例6において噴霧乾燥にて調製した、ハロペリドール含量24.5%(m/m)を有するポリマー塩を錠剤の調製に使用した。
製剤:
ここで、実施例6に記載の通り調製した、ロペラミドと実施例1によるコポリマーとの本発明に係る固溶体を、ロペラミドと同一コポリマーとの固体塩と、またロペラミドとPVP K17との固溶体と比較した。ロペラミドとコポリマーとの固溶体は、当該物質のTHF/メタノール溶液を蒸発させることによって得た。ロペラミドとPVPとの固溶体は次のように得た: ロペラミド(塩基)1部とPVP K17 9部とをDMFに溶解させた。固体濃度は25%(m/m)であった。溶液をゴムシート上へと注ぎ、50℃及び10mbarで真空乾燥キャビネット中で48時間乾燥させた。次いで、得られた固溶体を、ゴムシートから取り外し、25000rpmでチューブミル(Model Tube Mill control、IKA)中で粉末へ粉砕した。
調査には、TA Instruments製のNano ITC (Isothermal Titration Calorimeter)を使用した。それぞれのポリマーを測定セルに最初に投入した。引き続いてロペラミドをそこに添加した。反応が起こると、試料の温度が変化する。この温度差はペルチェ素子を介して自記され且つ補償された。補償に要する電気エネルギーを記録した。このエネルギー量は、生じた又は消費された反応熱量に同一である。
この調査は、TA Instrument製のSolCalインサートを備えたTAM IIIを使用して実施した。溶媒をそこの中に最初に投入した。溶解予定の試料をガラスアンプルに密封した。アンプルを溶媒へと導入し、温度を平衡化させた。溶液熱量測定を25℃(公称温度)で実施した。
