摘要
新型药物递释系统对提高药物的治疗效果、降低毒副反应具有重要作用,是药剂学领域的重要研究方向,目前已有诸多新型递药系统上市或正在研发中。根据其性质主要可以分为速效递药系统、长效递药系统和高效递药系统。本文拟对目前热点关注的新型递药系统进行综述,并对其中存在的问题进行分析和讨论。
The development of pharmaceuticals has been providing many kinds of novel drug delivery systems,which are important for improving therapeutic effect and one of the most important fields in pharmaceutics. According to their application,we can generally divide the novel drug delivery systems into three categories： quickly performed drug delivery system,long-term drug delivery system and high effective drug delivery system. Some diseases,such as asthma,angina pectoris and migraine,require therapeutics urgently,and the drugs have to be absorbed in several minutes. Therefore,quickly performed drug delivery systems are developed,such as oral disintegrating tablets and nasal spray. For normal tablets and capsules,especially the drugs with short blood half life,the drug concentration in blood shows obvious peak-valley phenomenon,which reduces the therapeutic effect and requires multiple administration. To solve this problem,sustained drug release system was developed,which could release the drugs slowly and sustainably even in zero-order kinetics. The pulse drug delivery system was developed that can delayed and pulsed release drug for one or several times. This system is especially useful in the management of asthma and heart disease,which are often found in midnight or early morning when patients are in bed. Transdermal drug delivery system could release drugs sustainably and deliver the drugs through skin to blood circulation,providing long term activity. The water-insoluble drugs are difficult for pharmaceutical development,thus many methods were developed to improve the solubility and bioavailability of drugs. Although biopharmaceuticals are important for disease treatment,the application shadows by the poor stability and low bioavailability. Thus the biopharmaceutical delivery system was developed,which mainly focused on structure modification and encapsulation by carriers. Considering therapeutic effect requires interaction between drugs and their targets,it is important to deliver drugs to their targets. Therefore,targeting delivery systems were developed,which mainly based on the nanoparticles. Furthermore,on-demand release drug delivery systems are also developed with the property of environment-triggered drug release. In conclusion,the novel drug delivery systems were reviewed in this study.
