4. What is the registration procedure of veterinary drugs (pharmaceuticals) and animal feed in America?
Section 510 of the Federal Food, Drug, and Cosmetic Act requires manufacturers, re-packers, and re-labelers that engage in the manufacture, preparation, propagation, compounding, or processing of human or veterinary drugs and human biological products to register their establishment(s) and submit a listing of every product in commercial distribution with the FDA. This information helps FDA maintain a catalog of all human and veterinary drugs and biologics in commercial distribution in the United States.
There is a fairly standard set of details which a person must provide, when applying to register a drug. Apart from details of the applicant (name, address, contact details, etc.), detailed information is commonly required in order to compile a dossier on the drug, in particular –
- name, ingredients, manufacture, pharmacology, toxicology;
- registration details elsewhere;
- purpose, route of administration, dosage, side effects, contra-indications;
- container, packaging and labeling.
