比較例2、5、6、7、8には、保存中、主薬が沈殿した現象が存在し、比較例3、4は理想的な注射用水溶液を調製できなかった。本効果実験例は実施例1~8及び比較例1、8で調製したテニポシド組成物に対して希釈安定性実験を行い、この実験には、テニポシド組成物を生理食塩水又は5%ブドウ糖溶液で50mL、100mL、250mL及び500mLに希釈させ、各希釈体積で6部調製し、室温と自然光照条件で0.5時間と12時間静置して、沈殿情況を記録した。沈殿が現れたサンプルの数を記録した。表1及び表2の結果から見れば、希釈体積と静置時間の増加に従い、市販製剤の模倣品が沈殿した割合は著しく増加し、実施例1~8で調製したサンプルは希釈実験での安定性が良好であった。低真空と高真空という2ステップで有機溶剤を分離することは、直接高真空で有機溶剤を分離することより、安定性がよい。希釈操作プロセスにおいて、市販製剤の模倣品の吸い取りと注射プロセスにおいて、動作をできるだけ優しくさせて、そうでないと、素早く結晶化することが分かる。本発明により提供される注射剤はこのような現象が存在しない。表1及び表2の結果によれば、模倣市販製剤と本発明における製剤は、生理食塩水と5%ブドウ糖希釈液における希釈安定性に差異がない。
