靶向制剂是以药物能在疾病靶区浓集为主要特点的一大类制剂的总称,最突出的特点是能将治疗药物最大限度地运送到靶区,使治疗药物在靶区浓集超出传统的数倍乃至数百倍,治疗效果明显提高,同时减少药物的用量,降低药物不良反应,而且便于控制给药的速度和方式,达到高效低毒达到治疗效果。近年来靶向给药的研究取得了令人鼓舞的进展,本文针对近几年靶向给药在各脏器的研究进展进行综述,以了解靶向给药在各脏器的应用现状。 Targeted agents are the general term for a broad class of agents that are characterized by the concentration of a drug at the target site of the disease. The most prominent feature is the ability to deliver the therapeutic drug to the target zone to the maximum, allowing the therapeutic agent to concentrate beyond the target zone Traditional times or even hundreds of times, the treatment effect was significantly improved, while reducing the amount of drugs to reduce drug adverse reactions, but also easy to control the speed and mode of administration, to achieve high efficiency and low toxicity to achieve therapeutic effect. In recent years, the research on targeted drug delivery has made encouraging progress. In this paper, we reviewed the research progress of targeted drug delivery in various organs in recent years to understand the application status of targeted drug delivery in various organs.
