The microspheres may contain various ingredients. E.g. perflutren
suspension in microspheres of phospholipids is classfied in V08DA04.
Perflenapent covers structural isomers of dodecafluoropentane i.e.
perflisopent.
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-touse
radiopharmaceuticals, can be given more than one (5th level) ATC
code, e.g. Technetium ( 99m Tc) exametazime (V09AA01) and technetium
