V VARIOUS

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


V01 ALLERGENS
V03 ALL OTHER THERAPEUTIC PRODUCTS
V04 DIAGNOSTIC AGENTS
V06 GENERAL NUTRIENTS

This group comprises nutrients for oral use, incl. preparations used in feeding with stomach tube. Solutions for parenteral nutrition are classified in B05BA.

V07 ALL OTHER NON-THERAPEUTIC PRODUCTS
V08 CONTRAST MEDIA

This group comprises X-ray, MRI and Ultrasound contrast media. The X-ray contrast media are subdivided into iodinated and non-iodinated compounds, and are further classified according to water solubility, osmolarity and nephrotropic/hepatotropic properties. High osmolar substances correspond mainly to ionic substances, except from ioxaglic acid, which is classified together with the non-ionic substances. MRI contrast media are subdivided according to magnetic properties.

V09 DIAGNOSTIC RADIOPHARMACEUTICALS

An expert group consisting of Dik Blok (the Netherlands), Per Oscar Bremer (Norway) and Trygve Bringhammar (Sweden) is 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.

V10 THERAPEUTIC RADIOPHARMACEUTICALS

Radiopharmaceuticals for therapeutic use are classified in this group, while radiopharmaceuticals for diagnostic use are classified in V09 - Diagnostic radiopharmaceuticals.

See comments to V09.

V20 SURGICAL DRESSINGS

A detailed classification of surgical dressings is prepared and maintained by the Ministry of Defence in the UK.
