限定日剂量 (DDD)

DDD Calculation Example

计算示例

在本视频中,William Malcolm 使用单个患者的处方口服阿莫西林 WHO DDD 为您展示 DDD 计算的示例。请记住,这用于计算标准化剂量,而非临床剂量。

值得注意的是,经常会有人问,相同的抗生素口服或注射给药的 DDD 是否相同。在很多情况下,确实相同。例如,阿莫西林无论口服还是注射 DDD 均为 1 克。同样,氟氯西林无论口服还是肠胃外 DDD 均为 2 克。但是,也有一些常用抗生素的口服和肠胃外给药 DDD 并不相同。在这类情况中,通常要么是因为口服和注射给药的生物利用度不同,要么是口服或注射给药用于差别极大的感染类型。
