Current through Register Vol. 43, No. 39, September 26, 2024
(a) Furosemide may
be administered to any horse that is entered in a race meeting, subject to the
requirements of these racing regulations. Except upon the instructions of the
animal health officer or an assistant animal health officer to remove the horse
from the veterinarian's list or to facilitate the collection of a post-race
urine sample, the administration of furosemide shall be permitted only if all
of the following requirements are met.
(1)
The animal health officer or an assistant animal health officer shall place the
horse's name on the bleeder list or the furosemide list, or on both lists.
(2) The furosemide shall be
administered at a location approved by the animal health officer or an
assistant animal health officer and at least four hours before post time for
the race in which each horse is entered, unless otherwise authorized in advance
by the animal health officer or assistant animal health officer.
(3) Furosemide shall be administered only by
a practicing veterinarian designated by the trainer to administer the
furosemide to each horse under the supervision of the animal health officer or
an assistant animal health officer.
(4) No dose of furosemide administered shall
exceed 250 milligrams, unless otherwise authorized in advance by the animal
health officer or an assistant animal health officer. In addition to the dosage
restriction specified in this paragraph, furosemide shall be administered only
intravenously and only in a single injection.
(5) Each horse to which furosemide is
administered shall remain under the care, custody, and control of the trainer
or the designated representative from the time the furosemide is administered

(7) The use of furosemide shall be required
to be approved in advance and shall be subject to the following requirements:
(A) The specific gravity of post-race urine
samples shall be measured to ensure that the specific gravity (sg) of the urine
is 1.010 or higher. If the sg of the post-race urine sample is below 1.010,
quantitation of furosemide in serum or plasma shall then be performed.
(B) When a serum or plasma sample
is quantitated, the concentration of furosemide in the sample shall not exceed
100 nanograms per milliliter of serum or plasma. Each concentration above 100
ng/ml shall be deemed a violation of this regulation.

medication to any horse entered to race except upon authorization of the animal

entered to race. The NSAID administered shall be one of the following
authorized drug substances:
(A)
Phenylbutazone in a dosage amount so that the test sample taken after the race
contains no more than 5.0 micrograms of drug substance per milliliter of blood
plasma or serum;
(B) flunixin in a
dosage amount so that the test sample taken after the race contains no more
than 20 nanograms of drug substance per milliliter of blood plasma or serum; or
(C) ketoprofen in a dosage amount
so that the test sample taken after the race contains no more than 10 nanograms
