April 10, 2026, Version 20.0

ASSOCIATION OF RACING COMMISSIONERS INTERNATIONAL-2026.

Association of Racing Commissioners International 2365 Harrodsburg Road, Suite B-450

Lexington, Kentucky USA 40504 www.arci.com

The Preamble to the Uniform Classification Guidelines was approved by the RCI Drug Testing and Quality Assurance Program Committee (now the Drug Testing Standards and Practices Program Committee) on August 26, 1991. Minor revisions to the Preamble were made by the Drug Classification subcommittee (now the Veterinary Pharmacologists Subcommittee) on September 3, 1991.

"The Uniform Classification Guidelines printed on the following pages are intended to assist stewards, hearing officers and racing commissioners in evaluating the seriousness of alleged violations of medication and prohibited substance rules in racing jurisdictions. Practicing equine veterinarians, state veterinarians, and equine pharmacologists are available and should be consulted to explain the pharmacological effects of the drugs listed in each class prior to any decisions with respect to penalties to be imposed. The ranking of drugs is based on their pharmacology, their ability to influence the outcome of a race, whether or not they have legitimate therapeutic uses in the racing horse, or other evidence that they may be used improperly. These classes of drugs are intended only as guidelines and should be employed only to assist persons adjudicating facts and opinions in understanding the seriousness of the alleged offenses. The facts of each case are always different and there may be mitigating circumstances which should always be considered. These drug classifications will be reviewed frequently and new drugs will be added when appropriate."

Preamble to the Uniform Classification Guidelines of Foreign Substances

Notes Regarding Classification Guidelines

• Where the use of a drug is specifically permitted by a jurisdiction, then the jurisdiction's rule supersedes these penalty guidelines. Regulators should be aware that a laboratory report may identify a drug only by the name of its metabolite. The metabolite might not be listed here, butthe parent compound may be. These classes of drugs are intended only as guidelines and should be employed only to assist persons adjudicating facts and opinions in understanding the seriousness of the alleged offenses.

• The facts of each case are different and there may be mitigating circumstances that should be considered. These drug classifications will be reviewed periodically. New drugs will be added or some drugs may be reclassified when appropriate.

• Racing Commissioners International (RCI) and/or the Racing Medication and Testing Consortium (RMTC) should be consulted for found substances or drugs not included in these guidelines and treated as Class 1 violations warranting a Class A penalty unless otherwise advised.

April 2026, Version 20.0

The RCI Drug Classification Scheme is based on 1) pharmacology, 2) drug use patterns, and 3) the appropriateness of a drug for use in the racing horse. Categorization is decided using the following general guidelines:

The list includes most drugs that have been reported as detected by racing authority laboratories in the United States, Canada, the United Kingdom and other Association of Official Racing Chemists (AORC) laboratories but does not include those which would seem to have no effect on the performance of the horse or drug detectability. For example, it does not include antibiotics, sulfonamides, vitamins, anthelmintics, or pangamic acid, all of which have been reported.

The list contains many drugs that have never been reported as detected. Usually, these are representatives of chemical classes that have the potential for producing an effect, and in many cases, for which at least one drug in that chemical class has been reported.

Most drugs have numerous effects, and each was judged on an individual basis. There are instances where there is a rather fine distinction between drugs in one category and those in the next. This is a reflection of a nearly continuous spectrum of effects from the most innocuous drug on the list to the drug that is the most offensive.

Classification Criteria

Pharmacology. Drugs that are known to be potent stimulants or depressants are placed in higher classes, while those that have (or would be expected to have) little effect on the outcome of a race are placed in lower classes.

Drug Use Patterns. Some consideration is given to placement of drugs based on practical experience with their use and the nature of positive tests. For example, procaine positives have in the past been associated primarily with the administration of procaine penicillin, and this has been taken into consideration in the placement of procaine into Class 3 instead of Class 2 with other injectable local anesthetics.

• Appropriateness of Drug Use. Drugs that clearly are intended for use in equine therapeutics are placed in lower classes. Drugs that clearly are not intended for use in the horse are placed in higher classes, particularly if they might affect the outcome of a race. Drugs that are recognized as legitimately useful in equine therapeutics but could affect the outcome of a race are placed in the middle or higher classes.

Classification Definitions

Class 1: Stimulant and depressant drugs that have the highest potential to affect performance and that have no generally accepted medical use in the racing horse. 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. Though not used as therapeutic agents, all DEA Schedule 1 agents are included in Class 1 because they are potent stimulant or depressant substances with psychotropic and often habituative actions. This class also includes all erythropoietin stimulating substances and their analogues.

Class 2: Drugs that have a high potential to affect performance, but less of a potential than drugs in Class 1. These drugs are

1) not generally accepted as therapeutic agents in racing horses, or 2) they are therapeutic agents that have a high potential for abuse. Drugs in this class include: psychotropic drugs, certain nervous system and cardiovascular system stimulants, depressants, and neuromuscular blocking agents. Injectable local anesthetics are included in this class because of their high potential for abuse as nerve blocking agents.

Class 3: Drugs that may or may not have generally accepted medical use in the racing horse, but the pharmacology of which suggests less potential to affect performance than drugs in Class 2. Drugs in this class include bronchodilators, anabolic steroids and other drugs with primary effects on the autonomic nervous system, procaine, antihistamines with sedative properties and the high-ceiling diuretics.

Class 4: This class includes therapeutic medications that would be expected to have less potential to affect performance than those in Class 3. Drugs in this class includes less potent diuretics; corticosteroids; antihistamines and skeletal muscle relaxants without prominent central nervous system (CNS) effects; expectorants and mucolytics; hemostatics; cardiac glycosides and anti-arrhythmics; topical anesthetics; antidiarrheals and mild analgesics. This class also includes the non steroidal anti-inflammatory drugs (NSAIDs), at concentrations greater than established limits.

Class 5: This class includes those therapeutic medications that have very localized actions only, such as anti-ulcer drugs, and certain anti-allergic drugs. The anticoagulant drugs are also included.

Prohibited Practices:

A) The possession and/or use of a drug, substance or medication, specified below, on the premises of a facility under the jurisdiction of the regulatory body for which a recognized analytical method has not been developed to detect and confirm the administration of such substance; or the use of which may endanger the health and welfare of the horse or endanger the safety of the rider or driver; or the use of which may adversely affect the integrity of racing:

1) Erythropoietin

2) Darbepoetin

3) Oxyglobin

4) Hemopure

B) The possession and/or use of a drug, substance, or medication on the premises of a facility under the jurisdiction of the regulatory body that has not been approved by the United States Food and Drug Administration (FDA) for use in the United States.

C) The practice, administration, or application of a treatment, procedure, therapy or method identified below, which is performed on the premises of a facility under jurisdiction of a regulatory body and which may endanger the health and welfare of the horse or endanger the safety of the rider or driver, or the use of which may adversely affect the integrity of racing.

Drug Classification Scheme

Class 1: Opiates, opium derivatives, synthetic opioids, psychoactive drugs, amphetamines, and all DEA Schedule I substances (see https://www.deadiversion.usdoj.gov/drugreg/schedule-1.html ), and many DEA Schedule II drugs.

Also found in this class are drugs that are potent stimulants of the CNS. Drugs in this class have no generally accepted medical use in the racing horse and their pharmacologic potential for altering the performance of a racing horse is very high. This class also includes all erythropoietin stimulating substances and their analogues.

Class 2: Drugs placed in this category have a high potential for affecting the outcome of a race. Most are not generally accepted as therapeutic agents in horse racing. 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 racing horse. The following groups of drugs are placed in this class:

A) Opiate partial agonists, or agonist-antagonists.

B) Non-opiate psychotropic drugs. These drugs may have stimulant, depressant, analgesic or neuroleptic effects.

C) Miscellaneous drugs, which might have a stimulant effect on the CNS.

D) Drugs with prominent CNS depressant action.

E) Anti-depressant and anti psychotic drugs, with or without prominent CNS stimulatory or depressant effects.

F) Muscle blocking drugs- those that have a direct neuromuscular blocking action.

G) Local anesthetics that have a reasonable potential for use as nerve-blocking agents (except procaine).

H) Snake venoms and other biologic substances that may be used as nerve-blocking agents.

Class 3: Drugs placed 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 racing horse. The following groups of drugs are placed in this class:

A) Drugs affecting the autonomic nervous system that 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 that 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) Primaryvasodilating/hypotensive agents.

E) Potent diuretics affecting renal function and body fluid composition.

F) Anabolic and/or androgenic steroids and other drugs.

Class 4: Drugs in this category comprise primarily 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)

B)

C)

D)

E)

F)

Non-opiate drugs that have a mild central antipyretic effect.

Drugs affecting the autonomic nervous system that do not have prominent CNS, cardiovascular, or respiratory effects:

1)

2)

3)

Drugs used solely as topical vasoconstrictors or decongestants.

Drugs used as gastrointestinal antispasmodics.

Drugs used to void the urinary bladder.

4) Drugs with a major effect on CNS vasculature or smooth muscle of visceral organs.

Antihistamines that do not have a significant CNS depressant effect. This does not include the H2 blocking agents, which are in Class 5.

Mineralocorticoid drugs.

Skeletal muscle relaxants.

Anti-inflammatory drugs. These drugs may reduce pain as a consequence of their anti-inflammatory action.

1) Non-steroidal anti-inflammatory drugs (NSAIDs). (Aspirin-like drugs).

2) Corticosteroids (glucocorticoids).

3) Miscellaneous anti-inflammatory agents. G. Less potent diuretics.

H. Cardiac glycosides and antiarrhythmic agents.

1. Cardiac glycosides.

2. Antiarrhythmic agents (exclusive of lidocaine, bretylium, and propranolol).

3. Miscellaneous cardiotonic drugs.

1. Topical Anesthetics - agents not available in injectable formulations.

J. Antidiarrheal drugs.

K. Miscellaneous drugs:

1. Expectorants with little or no other pharmacologic action.

2. Stomachics.

3. Mucolytic agents.

Class 5: Drugs in this category are therapeutic medications that have very localized actions only, such as anti ulcer drugs, and certain antiallergic drugs. The anticoagulant drugs are also included.
