ATC (Anatomical Therapeutic Chemical) Classification System
收藏资源简介:
ATC分类系统是一个用于药物分类的国际标准系统,由世界卫生组织(WHO)维护。该系统根据药物的解剖学、治疗学和化学特性对药物进行分类。ATC代码由五个字母组成,每个字母代表不同的分类层次。第一层代表解剖学主组,第二层代表治疗学亚组,第三层代表药理学亚组,第四层代表化学亚组,第五层代表具体的化学物质。
The ATC Classification System is an international standard drug classification system maintained by the World Health Organization (WHO). It classifies drugs based on their anatomical, therapeutic, and chemical characteristics. ATC codes consist of five letters, with each letter representing a distinct classification hierarchy. The first level represents the anatomical main group, the second level represents the therapeutic subgroup, the third level represents the pharmacological subgroup, the fourth level represents the chemical subgroup, and the fifth level represents the specific chemical substance.

- ATC分类系统首次由世界卫生组织(WHO)正式发布,旨在对药物进行系统分类,以便于药物的研发、监管和使用。
- WHO对ATC系统进行了重大修订,引入了第五级分类(ATC/DDD系统),增加了药物的日剂量(DDD)指标,以标准化药物使用量的比较。
- ATC分类系统被广泛应用于全球多个国家的药物监管和医疗保健系统,成为药物分类和使用的重要标准。
- WHO发布了ATC系统的最新版本,进一步细化了药物分类,并更新了药物的DDD值,以反映最新的临床实践和药物使用情况。
