Equine Drug Testing, Medication Regulation Book Released

Wind Publications released the fourth edition of “World Rules for Equine Drug Testing and Therapeutic Medication Regulation” on Feb. 14 and has sold more than 100 copies. Thomas Tobin, MVB, MSc, PhD, MRCVS, DABT, professor at the University of Kentucky Gluck Equine Research Center; Kimberly Brewer, DVM, a private practitioner; and Kent Stirling, executive director of the Florida Horsemen’s Benevolent and Protective Association authored the 286-page book. 

 
The newly released fourth edition covers medication rules around the world for the first time and features a forward written by Kentucky First Lady Jane Beshear. The book addresses specific regulatory procedures in place around the world to regulate the use of therapeutic medications and endogenous, dietary, and environmental substances in racing and performance horses. The book is based on the Association of Racing Commissioners International (ARCI) classification system for foreign substances and lists many of the specific regulatory thresholds/withdrawal time guidelines in place for the approximately 99 such substances--from acepromazine to xylazine--in use around the world. 
 
Some widely used therapeutic medications are associated with an unusually high risk of inadvertent identifications or overages; where appropriate, each of these substances is marked with a Horsemen’s Alert, which sets forth the reasons for the alert and suggests avoidance actions. Additionally, and somewhat unusually, three substances are listed as Chemist’s Alerts, with explanations provided. 
 
Regulatory thresholds are defined as plasma or urinary concentration of drugs/drug metabolites and are the essential regulatory tools. What the horseperson needs, however, are withdrawal time guidelines: simple, unambiguous medication administration guidelines scientifically linked to the regulatory threshold and which serve to greatly reduce the probability of a therapeutic medication “overage.” Appendix 1 of the book reviews the critically important matter of withdrawal time guidelines and the factors influencing withdrawal time guidelines in some detail. 
 
Many horse people are unfamiliar with the language of equine forensic science. Appendix 2, therefore, presents the language, definitions, and abbreviations used. Appendix 3 lists the equine therapeutic medications identified by the American Association of Equine Practitioners and by the Racing Medication and Testing Consortium; it is noted the therapeutic medication status of some of these substances is under review. Appendix 4 sets forth the need for suitable reference standards for therapeutic medication regulation and outlines National and local Horsemen's Benevolent and Protective Associations’ (HBPAs) contributions in this critically important area of forensic science. Appendix 5 lists the HBPAs that have supported these research efforts, and the book closes with Appendix 6, a list of scientific references.
