WHO DDD - Defined Daily Dose

  1. Defined Daily Dose (DDD) Index.
    • The DDD is the assumed average maintenance dose per day for a drug used for its main indication in adults.
    • DDDs provide a fixed unit of measurement independent of price, currencies, package size and strength enabling the researcher to assess trends in drug consumption and to perform comparisons between population groups.
    • The DDD is (to the best of my knowledge) not part of the EU PMS implementation

Tbd. Maybe not IDMP Scope
