国际控制释放学会每年召开一次生物活性物质控制释放讨论会。1984年7月23日至25日在美国佛罗里达州的Fort Landande 召开了第11届生物活性物质控制释放国际讨论会,300多名会员分别就口服剂型、靶向作用、透皮作用、微型包囊、类脂体、抗生素、农药和新系统等专题宣读近80篇论文。本文简要介绍药物控制释放系统研究的新进展。聚合物是控制释放系统的主要材料之一。近年来为适应不同药物所需的不同释放特性,采用了各种类型的聚合物。生物溶蚀聚合物常用作植入剂的材料,聚原酸酯[Poly(orthoesters)]是其中最常用的一种聚合物。聚原酸
The International Institute for Controlled Release convenes an annual biologically active substance control release seminar. The 11th International Symposium on Controlled Release of Bioactive Substances was held in Fort Landande, Florida from July 23 to July 25, 1984 with more than 300 members on oral dosage forms, targeting, transdermal, microencapsulation Nearly 80 papers were read out on topics such as lipids, antibiotics, pesticides and new systems. This article briefly introduces new advances in drug controlled release systems. Polymers are one of the major materials for controlled release systems. In recent years to adapt to the different release characteristics required by different drugs, using various types of polymers. Bioerodible polymers are commonly used as materials for implants. Poly (orthoesters) are among the most commonly used polymers. Poly acid
