Abstract
Description
本開示は、一般には、薬剤製造の分野、より具体的には、新規剤形を生成するための医薬有効成分(API)の熱動力学的混合に関する。
製薬産業によって用いられる現行の高処理量分子スクリーニング法は、新しく発見された難水溶性の分子実体の比率の非常な増大をもたらした。これらの分子の多くの治療的可能性は、不良な薬動力学的特性により、分子が開発中に放棄されるため、または生成物の性能が最適以下であるため、十分に実現されないことが多い。また、近年、製薬産業は、中性または弱酸性/塩基性薬物の塩形成および化学修飾の実際上の制限により、薬物溶解性を改善するための製剤法に、より大きく頼り始めている。結果として、難水溶性薬物の溶解特性の増強を目指す進化した製剤技術が、現代の薬物送達にとってますます重要になりつつある。
以下の図面は本明細書の一部を形成し、本開示のある特定の局面をさらに示すために含まれる。本開示は、これらの図面の1つまたは複数を、本明細書において示す具体的態様の詳細な説明と組み合わせて参照することにより、よりよく理解されるであろう。
本開示の様々な態様の作製および使用を以下に詳細に論じるが、本開示は多様な文脈において具体化しうる多くの発明概念を提供することが理解されるべきである。本明細書において論じる特定の局面および態様は、本開示を作製および使用するためのやり方の例示にすぎず、本開示の範囲を限定するものではない。
