An irinotecan liposome preparation, a preparation method, and use. The irinotecan liposome comprises irinotecan and liposome carriers, and internal aqueous phases located inside a liposome membrane and an external aqueous phase located outside the liposome membrane, the irinotecan is encapsulated in the internal aqueous phases, and a sulfonate gradient exists between the internal aqueous phases inside the liposome membrane and the external aqueous phase outside the liposome membrane. The liposome takes monovalent sulfonate and disulfonate as the internal water phases, encapsulates the irinotecan in the form of insoluble sulfonate and disulfonate in the aqueous phases of the liposome, and has a good sustained-release effect.
一种伊立替康脂质体制剂、制备方法及用途。该伊立替康脂质体包括伊立替康和脂质体载体,以及位于脂质体膜内的内水相和位于脂质体膜外的外水相,伊立替康被包裹在内水相,脂质体膜内的内水相和脂质体膜外的外水相之间存在磺酸盐梯度。脂质体以单价磺酸盐和二磺酸盐作为内部水相,以不溶性磺酸盐和二磺酸盐的形式将伊立替康包裹在脂质体的水相中,具有良好的缓释效果。
