A veterinary drug is approved for sale in Canada if the manufacturer has supplied evidence that the drug:
- is safe for the animals to be treated;
- is effective treating the condition for which it is to be marketed;
- will not pose any demonstrable health hazard to humans eating the food product from treated animals, when the drug is used according to label directions, and
- is manufactured according to strict specifications and remains stable up to its expiry date.
No. All submissions to the VDD for the approval of a drug are confidential. On a weekly basis, the Therapeutic Products Directorate publishes a listing of the drug products that have received a Notice of Compliance (NOC) for products classified as 'new drugs'.
No. Every veterinary drug sold in Canada must first be approved by the VDD and issued a DIN. However, in special circumstances (medical emergencies), the veterinarian may ask the VDD to authorize the sale of a limited quantity of an unapproved drug to the veterinarian for use in a specific emergency.
The Emergency Drug Release Program allows veterinarians to obtain limited quantities of drugs not approved for sale in Canada for the emergency treatment under their direct medical supervision. Veterinarians may ask the VDD, which may then recommend to the Health Protection Branch, that the manufacturer be authorized to sell them a limited quantity of the drug for emergency use. The manufacturer must provide adequate evidence to the VDD that the drug poses no known health risk to the animals being treated or to humans. The veterinarian assumes full responsibility for the safety of the animals treated and for any drug residue violations in food-producing animals.
Drug manufacturers must apply to the Veterinary Drugs Directorate for permission to sell a drug in Canada. The manufacturer must provide the evidence required by the VDD to demonstrate that the drug will be safe and effective. All new veterinary drugs must be approved by the VDD and assigned a Drug Identification Number (DIN) before they can be sold in Canada.
The VDD establishes a specific withdrawal period for each new drug it approves. The withdrawal is treatment-free period before an animal, or food products taken from the animal, can be used for human consumption. This time allows the drug and its residues to decrease to levels that do not pose any demonstrable health risk to humans eating the food. The withdrawal period is stated on the drug label along with other instructions for proper use of the drug.
In addition, federal and provincial food inspection systems monitor food regularly for drug residue violations.
The label must contain the name of the drug, the Drug Identification Number, the words "For Veterinary Use Only" and warnings and cautions about health hazards for humans and animals, either through direct contact with the drug or through residues in food products.
In addition, the label must include the manufacturer's name and address, the production lot number, a list of medicinal ingredients, an expiry date and adequate directions for the use of the drug.
Off-label use of any drug should be avoided whenever an approved product is available. Veterinarians who choose to make use of a drug in an off-label manner are responsible for the safety of the animals being treated and for any illegal drug residues that are detected in animals and animal products sold for human consumption.
Go to the Notices of Compliance page to see recent NOC's, either for Drugs or Medical Devices. More information on NOC's, as well as who to call if you require further help is available on those pages.
For a list of all drugs approved in Canada go to the Drug Product Database.There is currently no online database of Medical Devices on the Canadian market, for more information contact the Device Notification Section at (613) 957-1909.
The definition of a new drug is found in section C.08.001 (a)(b)(c) of the Food and Drug Regulations. Any product which doesn't fall under this definition is regulated as a Not-New Drug ('old drug').
This link will bring you to a list of pharmaceutical ingredients (also called active or medicinal ingredients) which have been deemed by the Veterinary Drugs Directorate to be "new drugs". A drug which contains one or more of the pharmaceutical ingredients on this list will be regulated as a "new drug", as per section C.08.001 (a). There are other factors besides the active ingredient which affect the status of the drug, including new combinations of drugs, new claims, different dosage forms or routes, etc. Each drug submission is evaluated by the Veterinary Drugs Directorate to determine new vs. not-new status.
There are several useful web links with this information.
