Definition

The DDD (or Define Daily Dose) is defined by the World Health Organization (WHO) as the average dose of active ingredient recommended per day for a drug used for its main indication in adults.
Only one DDD is assigned per WHO ATC classification code and route of administration.
You can find more information on the WHO website: https: //www.whocc. no / atc_ddd_index /
The DDD per box expresses the number of days of treatment recommended for a box.

Example

Let us take the example of a box containing 30 capsules (BU or base units) each containing 50 milligrams of the active principle PA.
The dosage of active principle in the box is:
Number of basic units of the box x dosage of active principle of one base unit
Either: 30 capsules x 50 mg = 1.500 MG of active ingredient PA for one box.
The DDD of this product is 300 MG per day.
Then the DDD per box is calculated by: Dosage of active principle in the box / DDD
= 1,500 / 300, ie 5 days of recommended treatment.

Terminology

The DDD per box indicator can be translated into English as "DDD per package".

Limitation

This indicator is only available for pharmacies data and only for drugs
