ATC/DDD- what we learnt at WHO TBS

[Guest guest]

Hello All, The Anatomical Therapeutic Chemical classification and defined daily dose assignment (ATC/DDD) is a system wherein the medicines are divided into different groups according to the organ / system, on which they act, and their chemical, pharmacological and therapeutic properties. DDD is the assumed average maintenance dose per day for a medicine used for its main indication in adults. It is

a tool for presenting drug utilization statistics with the aim of improving drug use. This system has been demonstrated to be suitable for--- 1. National and international comparisons of drugs. 2. Evaluation of long term trends across nations 3. Assessing the impact of certain events on drug use. 4. Providing data in investigations of drug safety. The drug utilization research group (DURG) was established in 1969.It was given the task of development of internationally applicable method for drug utilization research. Subsequently the ATC/DDD system was developed and used for the first time in 1976.(Main contribution is of Norwegian researchers) This post appears like class room teaching. But now I would like you to share with me your opinions on the use and misuse of this system and the limitations of using ATC/DDD method. kunda
