摘要 靶向给药系统(targeting dmg delivery system,TDDS)又称靶向制剂,是通过载体使药物选择性的浓集于病变部位的给药系统。病变部位常被称为靶部位,可以是靶组织、靶器官,也可以是靶细胞或细胞内的某靶点。靶向给药可以增加药物在靶部位的浓度、降低药物在非靶部位的浓发、延长药物在靶部位的停留时间,从而提高给药后的疗效。药物制剂靶向系统需要建立一个能够全面、客观、准确地反映靶向性的评价体系,一方面可对制剂的靶向性有一个可视化的数据或图、表支持;另一方面可为制剂进行条件优化提供实验依据,因此为靶向性建立一个好的评价体系是在研究靶向制剂过程中必不可少的。靶向制剂的研制需要有可靠的评价标准来约束,这就刺激了各种评价标准的研究,建立好的评价标准,可以指导靶向制剂的研制,使其能够更好的满足临床的需要。本文就目前在药物靶向制剂领域应用比较广泛的靶向性评价方法进行综述。
