Most of countries have their own list of drugs/ medical devices that are approved to use/sale on their territory. Lists are updated periodically, with information on new approvals, exemptions, re-classifications, etc. It’s really hard to stay up to date.
You should take a look at the list of substances intended for veterinary use in your country. The approvals may differ depending on member state. Countries within EU can implement their own legislation, establishing more harsh rules.
Probably you will find the file of your interest browsing Ministry of Agriculture website.
I know that's not a comprehensive answer, but I hope it will help just a little.
