Specific veterinary groups<br />
Specific veterinary groups have been created, e.g. for immunologicals (QI), to allow a<br />
subdivision by species. The ATC system’s subdivision of sulfonamides on the basis of their<br />
biological half-life in humans is irrelevant to veterinary use and a veterinary classification has<br />
therefore been established (QJ01EQ). A specific classification has also been established for<br />
antiparasitic products (QP), since there are considerable differences in the use of these products<br />
and the variety of substances available, compared with the situation in human medicine.<br />
When specific ATCvet codes are created, the following digits/letters in the ATC system are<br />
reserved for use in the ATCvet classification system:<br />
level 1: Q<br />
level 2: 50-69<br />
levels 3 and 4: Q, V, W, Y and Z<br />
level 5: 90-99<br />
At level 5, the digits 90-98 are used to classify products containing plain substances, while 99<br />
has been used for combined products.<br />
Example:<br />
QJ51 - Antibacterials for intramammary use, and QA07CQ - Oral rehydration formulations<br />
for veterinary use, are examples of ATCvet codes for which there are no equivalents in the<br />
ATC system (i.e. neither J51 nor A07CQ exists in the ATC system).<br />
Classification problems are discussed by the ATCvet Working Group, which then decides on the<br />
final classification.<br />
Nomenclature in the ATCvet system<br />
- International Non-proprietary Names (INN) are preferred.<br />
If INN names have not been assigned, United States Adopted Names (USAN) or British<br />
Approved Names (BAN) are to be chosen.<br />
Lists of INN names are published by the World Health Organization (WHO), Geneva, and<br />
are published continuously in WHO Drug Information. Lists of USAN names are<br />
published by the US Phamacopoeia and lists of BAN names are available in the British<br />
pharmacopoeia.<br />
- Non-specific terms like others and various should be avoided as group/subgroup names<br />
whenever possible.<br />
