十一、载药微球未来
1. 载药微球-顺铂
![]()
ioxaglic and iohexol contrast the elution profile was similar with cisplatin fractions of 15%,40%,70% and 95% at 1,3,6 and 24 hours
respectively
![]()
• Conducted a preclinical study in vitro
• In vivo in patients with CRC measuring oxaliplatin concentration in target lesion (by biopsy) and plasma
• Highest of drug tested was 400mg oxaliplatin/50mg HepaSphere
• Working dose : 50mg oxaliplatin + 1 vial of Hepa 50-100 for 15min
3. 伊立替康- HepaSphere 文献 十二、结语 不可吸收的药物洗脱微球荷载细胞毒性药物已经在不断地发展之中。经动脉注射后,药物洗脱微球可以缓慢地释放药物增强对肿瘤的疗效,并增加缺血的强度和时间。 不幸的是,尽管载药微球在理论上的优势,和在早期关键研究出现令人鼓舞的结果,但载药微球优于常规TACE的明确资料仍然缺乏 1.
