Editing Template:Infobox drug/doc (section)

==== ATC, ATCvet ====

{{see|Wikipedia:WikiProject Pharmacology/Style guide#Use ATC codes}}
Where the drug is not included in ATC coding system (as opposed to its value just not been entered into the template) then set '''ATC_prefix''' to 'none', and the article is automatically added to [[:Category:Drugs not assigned an ATC code]]:
<syntaxhighlight lang="wikitext">
| ATC_prefix        = none
</syntaxhighlight>

Additional ATC(vet) may be included with the optional {{para|'''ATC_supplemental'''}} parameter as a comma-separated list. ATC templates may be used to have these additional codes link to the relevant databases:
<syntaxhighlight lang="wikitext">
| ATC_supplemental ={{ATC|M02|AA15}}, {{ATCvet|S01|BC03}}
</syntaxhighlight>
Adds the following linked codes:
:For ATC – {{ATC|M02|AA15}}, {{ATCvet|S01|BC03}}

Veterinary drugs are placed in a slightly different classification system, [[Anatomical Therapeutic Chemical Classification System#ATCvet|ATCvet]]. The code may be specified as ATCvet by setting the parameter '''ATCvet''' to 'yes'. Do not include the leading 'Q' in '''ATC_prefix''':
<syntaxhighlight lang="wikitext">
| ATCvet            = yes
| ATC_prefix        = N05
| ATC_suffix        = AX90
</syntaxhighlight>
When the ATCvet code happens to be the same as the ATC for a mainly human drug, it is usually a better idea to just provide the ATC in the infobox.
