Why must target species, indication, dose and route be treated as one approved set?

Evidence and authorisation are tied to defined conditions of use. A dose established for cattle cannot simply be transferred to sheep, goats, poultry or horses, and a route or indication cannot be expanded because the active ingredient is familiar. Buyers should compare every proposed catalogue or tender statement with the approved product information. Unapproved extrapolation can create safety, efficacy, residue and legal risks and should be referred to a veterinarian and regulatory specialist.
