Description
Claims (10)
- アルキレンオキシド単量体から重合された重合体およびアミン官能性を含む医薬品化合物を含む粒子を製造する方法であって、(i)アルキレンオキシド単量体を重合して重合体を製造し、その後、重合体の分子量を減少させるために重合体にγ線または電子ビームを酸素がある状態で照射し、それによって質量平均分子量が100,000〜2,000,000g/gmoleであり、そして粒子の全質量を基準にして200〜2,000質量ppmのギ酸化合物を有する重合体の粒子を製造する工程、(ii)粒子の表面をギ酸のpKa(3.75)より低いpKaを有する処理酸と接触させ、ギ酸化合物の量を粒子の全質量を基準にして10〜200質量ppmに減らす工程、および(iii)アミン官能性を含む医薬品化合物を粒子と組み合わせる工程を含むことを特徴とする方法。
- 粒子は中心部と外表面を有し、さらにギ酸化合物の濃度が外表面よりも中心部で高いギ酸化合物濃度勾配を有することを特徴とする請求項1に記載の方法。
- 粒子の半径方向断面に沿って最も外側の10%にギ酸化合物の合計量の5質量%未満が存在するような濃度勾配であることを特徴とする請求項2に記載の方法。
- アルキレンオキシド単量体がエチレンオキシドであることを特徴とする請求項1に記載の方法。
- 重合体がエチレンオキシドおよびエチレンオキシド以外の1つまたはそれ以上のアルキレンオキシドから重合されることを特徴とする請求項1に記載の方法。
- アミン官能性を含む化合物が第二級アミン官能性を含む薬理学的に活性な化合物であることを特徴とする請求項1に記載の方法。
- 工程(ii)後の粒子が粒子の全質量を基準にして10〜150質量ppmのギ酸化合物を含むことを特徴とする請求項1に記載の方法。
- 酸がフッ化水素酸、硫酸、硝酸、チオ硫酸、リン酸、シトラコン酸、クエン酸、ジクロロ酢酸、シュウ酸、メタンスルホン酸、マロン酸およびそれらの混合物からなる群から選ばれることを特徴とする請求項1に記載の方法。
- 酸がメタンスルホン酸であることを特徴とする請求項8に記載の方法。
- (i)重合体粒子からのギ酸化合物の抽出を促進するのに効果的な条件下で処理酸を含む液体媒体中に重合体粒子のスラリーを形成すること、および(ii)ギ酸化合物の量が減少した処理された微粒状重合体粒子を回収することからなる請求項1に記載の方法。
