Provided are a method for preparing liposomes comprising ultrasound reactive microbubbles for drug delivery, comprising (a) a step of producing ultrasound reactive microbubbles comprising an inert gas therein and having a first shell formed on the outer surface thereof, followed by forming a uniform size distribution of the ultrasound reactive microbubbles through an extruder; and (b) a step of producing liposomes comprising the ultrasound reactive microbubbles distributed in a uniform size and a medicament therein and having a second shell formed on the outer surface thereof, followed by forming a uniform size distribution of the liposomes through an extruder; and a liposome using same.
本发明提供了一种用于制备包含超声反应微泡的脂质体的方法,该方法用于给药,包括:(a) 第一步,生产包含惰性气体的超声反应微泡,并在其外表面形成第一外壳,然后通过挤压机形成大小分布均匀的超声反应微泡;和 (b) 生产脂质体的步骤,脂质体包括以均匀尺寸分布的超声反应微泡和其中的药物,并在其外表面形成第二外壳,然后通过挤压机形成均匀尺寸分布的脂质体;以及使用相同方法的脂质体。
