PERMITTED MEDICATIONS
Article A1003 Permitted Medications (General Rules Section
A)
A permitted medication is one that is allowed to be
used in accordance with EC Equine Medication rules during
any EC sanctioned competition. EC permits the use of one
non-steroidal anti-inflammatory drug (NSAID) that is licensed
for use in horses in Canada. EC allows the use of anti-ulcer
medications in accordance with the FEI rules. Please note that
some discipline or breed rules (e.g. endurance) have additional
restrictions.
The following is a list of the specific medications permitted to
be used during EC sanctioned competitions.
? One Non-Steroidal Anti-inflammatory Drug (NSAID)
licensed for use in horses in Canada from the
following list: Note: If more than one NSAID is
found in any drug test sample, the test will be
deemed positive.
o Flunixin meglumine (Banamine)
? maximum permissible plasma or serum
concentration 1.0 microgram/ml
o Phenylbutazone (Bute)
? maximum permissible plasma or serum
concentration 15.0 microgram/ml
GUIDELINES FOR PERMITTED USE OF NSAIDS
(based on a 450kg/1000lb horse)
It is stressed that this information is presented only as a
guideline and should not be construed as absolute for
every horse. Because of this, following these guidelines will
not be considered a defense for a positive test.
Phenylbutazone:
The maximum permitted plasma concentration of
phenylbutazone is 15.0 micrograms per milliliter.
Guidelines: When phenylbutazone is administered,
the dose should be accurately calculated according to the
actual weight of the animal. Each 24 hours, not more than 4.5
milligram per kilogram (2.0 milligrams per pound) of body
weight should be administered, preferably less. For a 1,000
pound animal, the maximum daily dose is 2.0 grams, which
equals two 1.0 gram units of paste, or 10.0 ml of the injectable
(200 milligrams per milliliter). Neither a total daily dose nor
part of an injectable dose should be administered during the 12
hours prior to competing. In the event the phenylbutazone is
administered orally, half of the maximum daily dose (1.0 gram
per 1,000 lbs.) can be administered each 12 hours (i.e., 12
hours apart) during a five day treatment program even if such
oral administration occurs within 12 hours of competition.
Phenylbutazone should not be administered for more than five
consecutive days.
Flunixin Meglumine (Banamine):
The maximum permitted plasma concentration of Flunixin is
1.0 microgram per milliliter.
Guidelines: When flunixin meglumine (e.g.
Banamine) is administered, the dose should be accurately
calculated according to the actual weight of the animal. Each
24 hours, not more than 1 milligram per kilogram (0.5
milligrams per pound) of body weight should be administered.
For a 1,000 pound animal the maximum daily dose is 500
milligrams which equals 10.0 ml of the injectable (50
milligrams per milliliter) given intravenously. No part of a
dose should be administered during the twelve (12) hours prior
to competing. Any medicated feed must be consumed and/or
removed at least twelve (12) hours prior to competing. The
medication should not be used for more than five successive
days.
