This group comprises many different types of drugs, and assigning DDDs are difficult. Very few DDDs are assigned in this group.


An expert group has been responsible for the ATC classification of radiopharmaceuticals in V09 and V10. The group has also prepared the guidelines for classification of these products.
Radiopharmaceuticals for diagnostic use are classified in this group, while radiopharmaceuticals for therapeutic use are classified in V10. In general, the 3rd level are subdivided according to site of action or organ system, the 4th level according to radionuclide and the 5th level specifies the chemical substance. The ATC 5th level defines the actual form essential in nuclear medicine procedures, which includes radionuclide and carrier molecule. Therefore, products on the market, that can often be regarded as intermediate products rather than ready-to-use radiopharmaceuticals, can be given more than one (5th level) ATC code, e.g. technetium (99mTc) exametazime (V09AA01) and technetium (99mTc) exametazime labelled cells (V09HA02).
ATC codes are not assigned for radionuclide precursors which are used only in the radiolabelling of another substance prior to administration.

No DDDs have been assigned for radiopharmaceuticals.


This group comprises radiopharmaceuticals for the lung ventilation and lung perfusion studies.

V09EA Technetium (99mTc), inhalants

Technetium preparations for inhalation are classified in this group. Preparations with other indications when given intraveneously are classified according to such indications, e.g. technetium-pentetate is classified in V09C - Renal system.

V09EB Technetium (99mTc), particles for injection

Preparations containing smaller particles or colloids that are used for RES function are classified in V09D - Hepatic and reticulo endothelial system.
