RELATES TO: KRS 230.215, 230.225, 230.240, 230.260, 230.265, 230.290, 230.320, 230.370

NECESSITY, FUNCTION, AND CONFORMITY: KRS 230.215(2) authorizes the Kentucky Horse Racing Commission to promulgate administrative regulations prescribing conditions under which all legitimate horse racing and wagering thereon is conducted in Kentucky. KRS 230.240(2) requires the commission to promulgate administrative regulations restricting or prohibiting the administration of drugs or stimulants or other improper acts to horses prior to the horse participating in a race. This administrative regulation establishes the withdrawal guidelines for permitted drugs, medications, and substances that may be administered to race horses competing in Kentucky.

Section 1. The Kentucky Horse Racing Commission Withdrawal Guidelines Thoroughbred; Standardbred; Quarter Horse, Appaloosa, and Arabian.

(1) This administrative regulation shall provide certain mandatory treatment requirements, guidance, and advice on medication withdrawal intervals.

(2) These withdrawal guidelines regarding furosemide shall not apply to two (2) year-old or stakes horses pursuant to 810 KAR 8:010 Section 6.

(3)

(a) Unless otherwise specified in these withdrawal guidelines, KAR Title 810, or KRS Chapter 230, the following withdrawal guidelines in this section are voluntary and advisory. The guidelines are recommendations based on current scientific knowledge that may change over time.

(b) A licensee may present evidence of full compliance with these guidelines to the commission and the stewards as a mitigating factor to be used in determining violations and penalties.

(c) These withdrawal interval guidelines assume that administration of medications will be performed at doses that are not greater than the manufacturer's maximum recommended dosage, or the dosage recommended in this document. Medications administered at dosages above manufacturer's recommendations, in compounded formulations, or in combination with other medications or administration inside the withdrawal interval may result in test sample concentrations above threshold concentrations that could lead to positive test results and the imposition of penalties.

(d) The time of administration of an orally administered substance, for the purposes of withdrawal interval, shall be considered to be the time of complete ingestion of the medication by the horse via eating or drinking.

(e) For products containing multiple medications, the withdrawal time to be used should be no less than the longest identified for any of the individual constituent substances--even if that substance is not present in the highest concentration in the product.

(f) Brand names of medications, where applicable, are listed in parentheses following the generic name of a drug.
