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