AMENDATORY SECTION(Amending WSR 06-09-009, filed 4/10/06,
effective 5/11/06)
WAC 260-70-680
Uniform classification guidelines.
((The
following outline describes the types of substances placed in
each category. This list shall be publicly posted in the
offices of the official veterinarian and the racing secretary.
(1) Class 1
Opiates, opium derivatives, synthetic opioids,
psychoactive drugs, amphetamines and U.S. Drug Enforcement
Agency (DEA) scheduled I and II drugs. Also found in this
class are drugs which are potent stimulants of the nervous
system. Drugs in this class have no generally accepted
medical use in the racehorse and their pharmacological
potential for altering the performance of a race is very high.
(2) Class 2
Drugs in this category have a high potential for
affecting the outcome of a race. Most are not generally
accepted as therapeutic agents in the racehorse. Many are
products intended to alter consciousness or the psychic state
of humans, and have no approved or indicated use in the horse.
Some, such as injectable local anesthetics, have legitimate
use in equine medicine, but should not be found in a
racehorse. The following groups of drugs are in this class:
(a) Opiate partial agonists, or agonist-antagonists;
(b) Nonopiate psychotropic drugs, which may have
stimulant, depressant, analgesic or neuroleptic effects;
(c) Miscellaneous drugs which might have a stimulant
effect on the central nervous system (CNS);
(d) Drugs with prominent CNS depressant action;
(e) Antidepressant and antipsychotic drugs, with or
without prominent CNS stimulatory or depressant effects;
(f) Muscle blocking drugs, which have a direct
neuromuscular blocking action;
(g) Local anesthetics which have a reasonable potential
for use as nerve blocking agents (except procaine); and
(h) Snake venoms and other biologic substances, which may
be used as nerve blocking agents.
(3) Class 3
Drugs in this class may or may not have an accepted
therapeutic use in the horse. Many are drugs that affect the
cardiovascular, pulmonary and autonomic nervous systems. They
all have the potential of affecting the performance of a
racehorse. The following groups of drugs are in this class:
(a) Drugs affecting the autonomic nervous system which do
not have prominent CNS effects, but which do have prominent
cardiovascular or respiratory system effects (bronchodilators
are included in this class);
(b) A local anesthetic, which has nerve blocking
potential but also has a high potential for producing urine
residue levels from a method of use not related to the
anesthetic effect of the drug (procaine);
(c) Miscellaneous drugs with mild sedative action, such
as the sleep inducing antihistamines;
(d) Primary vasodilating/hypotensive agents; and
(e) Potent diuretics affecting renal function and body
fluid composition.
(4) Class 4
This category is comprised primarily of therapeutic
medications routinely used in racehorses. These may influence
performance, but generally have a more limited ability to do
so. Groups of drugs assigned to this category include the
following:
(a) Nonopiate drugs which have a mild central analgesic
effect;
(b) Drugs affecting the autonomic nervous system, which
do not have prominent CNS, cardiovascular or respiratory
effects;
(i) Drugs used solely as topical vasoconstrictors or
decongestants,
(ii) Drugs used as gastrointestinal antispasmodics,
(iii) Drugs used to void the urinary bladder,
(iv) Drugs with a major effect on CNS vasculature or
smooth muscle of visceral organs.
(v) Antihistamines, which do not have a significant CNS
depressant effect (this does not include H1 blocking agents,
which are listed in Class 5);
(c) Mineralocorticoid drugs;
(d) Skeletal muscle relaxants;
(e) Anti-inflammatory drugs--those that may reduce pain
as a consequence of their anti-inflammatory actions, which
include:
(i) Nonsteroidal anti-inflammatory drugs (NSAIDs);
(ii) Corticosteroids (glucocorticoids); and
(iii) Miscellaneous anti-inflammatory agents.
(f) Anabolic and/or androgenic steroids and other drugs;
(g) Less potent diuretics;
(h) Cardiac glycosides and antiarrhythmics including:
(i) Cardiac glycosides;
(ii) Antiarrhythmic agents (exclusive of lidocaine,
bretylium and propranolol); and
(iii) Miscellaneous cardiotonic drugs.
(i) Topical anesthetics--agents not available in
injectable formulations;
(j) Antidiarrheal agents; and
(k) Miscellaneous drugs including:
(i) Expectorants with little or no other pharmacologic
action;
(ii) Stomachics; and
(iii) Mucolytic agents.
(5) Class 5
Drugs in this category are therapeutic medications for
which concentration limits have been established as well as
certain miscellaneous agents. Included specifically are
agents, which have very localized action only, such as
anti-ulcer drugs and certain antiallergic drugs. The
anticoagulant drugs are also included.)) This section
classifies each drug/medication/foreign substance, and where
appropriate and/or available, its trade name. The penalties
for violation of this section are in WAC 260-84-110.
(1) Class 1
Class 1 drugs are stimulant and depressant drugs that have the highest potential to affect the performance of a horse, and have no generally accepted medical use. Many of these agents are Drug Enforcement Agency (DEA) Schedule II substances. These include the following drugs and their metabolites: Opiates, opium derivatives, synthetic opioids and psychoactive drugs, amphetamines and amphetamine-like drugs as well as related drugs, including but not limited to apomorphine, nikethamide, mazindol, pemoline, and pentylenetetrazol.

Class 2 drugs are drugs/medication/foreign substances that have a high potential to affect the performance of a horse, but less of a potential than class 1 drugs. Class 2 drugs are either not generally accepted as therapeutic agents in racing horses, or are therapeutic agents that have a high potential for abuse.
