In the ATC-Classification substances are divided into different groups according to the organ or organ system which they affect and their chemical, pharmacological and therapeutic properties.
A defined daily dose is assigned to each active substance. Defined daily doses (DDD) are the assumed average daily maintenance dose for the main indication of each substance in adults.
