Permitted medication.
Trainers using permitted medication in the care of their horses are subject to all rules governing such medications. Failure to administer permitted medication to a horse on a program of permitted medication is a violation of these rules.
(1) The use of one of three approved nonsteroidal anti-inflammatory drugs (NSAIDs) is permitted under the following conditions:
(a) The drug may not exceed the following permitted serum or plasma threshold concentrations, which are consistent with administration by a single intravenous injection at least 24 hours before the post time for the race in which the horse is entered:
(i) Phenylbutazone - 2.0 micrograms per milliliter;
(ii) Flunixin - 20.0 nanograms per milliliter;
(iii) Ketoprofen - 2.0 nanograms per milliliter.
(b) No NSAID, including the approved NSAIDs listed in this rule may be administered within the 24 hours before post time for the race in which the horse is entered.
(c) The presence of a second approved NSAID will be considered a Class B violation if the second of the approved NSAIDs is over the secondary threshold as follows:
(i) Phenylbutazone - 0.3 mcg per milliliter;
(ii) Flunixin - 3 ng per milliliter;
(iii) Ketoprofen - 1 ng per milliliter.
(d) Any unapproved NSAID in the post-race serum or plasma sample is not permitted. The use of all but one of the approved NSAIDs must be discontinued at least 48 hours before the post time for the race in which the horse is entered.
(2) Any horse to which a NSAID has been administered is subject to having a blood and/or urine sample(s) taken at the direction of an official veterinarian to determine the quantitative NSAID level(s) and/or the presence of other drugs which may be present in the blood or urine sample(s).
