Classification System of the PSS
Anatomical Therapeutic and Chemical Classification System (ATC)/Defined DailyDose (DDD)
| Description | The Anatomical Therapeutic and Chemical Classification System (ATC) divides drugs into different groups according to the organ or system on which they act and/or their therapeutic and chemical characteristics. The Defined Daily Dose (DDD) is the assumed average maintenance dose per day for a drug used for its main indication in adults. It is used to standardize the comparison of drug usage between different drugs or between different health care environments. (Administrative Order 2013-0025) |
