===== ATC, ATCvet and CAS =====

{{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:未分配ATC的藥物]] rather than [[:Category:Drugboxes with an unspecified ATC code]]<!---英維分欸已刪--->:
<pre>
| ATC_prefix        = none
</pre>
  
Additional ATC or CAS codes may be included with the optional  '''ATC_supplemental''' & '''CAS_supplement''' parameter as a comma-separated lists. CAS or ATC templates may be used to have these additional codes link to the relevant databases:
<pre>
| CAS_supplemental ={{CAS|427-51-0}} (acetate)
| ATC_supplemental ={{ATC|M02|AA15}}, {{ATC|S01|BC03}}  
</pre>
Adds the following linked codes:
:For CAS - {{CAS|427-51-0}} (acetate)
:For ATC - {{ATC|M02|AA15}}, {{ATC|S01|BC03}}

Veterinary drugs are placed in a slightly different classification system, [[解剖学治疗学及化学分类系统]]. The code may be specified as ATCvet by setting the parameter '''ATCvet''' to 'yes'. Do not include the leading 'Q' in '''ATC_prefix''':
<pre>
| ATCvet            = yes 
| ATC_prefix        = N05
| ATC_suffix        = AX90
</pre>
