V VARIOUS

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


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.


V08A X-RAY CONTRAST MEDIA, IODINATED
V08B X-RAY CONTRAST MEDIA, NON-IODINATED
V08C MAGNETIC RESONANCE IMAGING CONTRAST MEDIA
V08D ULTRASOUND CONTRAST MEDIA
