Research on Ethylphenidate in Horses Completed

POSTED ON  |  26-10-2018

Thee first of three Racing Medication and Testing Consortium (RMTC) tactical research studies conducted over the last year was published Oct. 16. Tactical research studies focus on detecting, identifying and inhibiting the use of illicit substances. The study, "L-and D-threo Ethylphenidate Concentrations, Pharmacokinetics and Pharmacodynamics in Horses," was funded with significant assistance from the American Quarter Horse Association (AQHA) Foundation. It was performed by Dr. Heather Knych at UC-Davis's K. L. Maddy Equine Analytical Chemistry Laboratory with the goal of preventing the use of the psychostimulant ethylphenidate in racing horses. The research was published in the October 2018 issue of Drug Testing Analysis. 
  • "I join the American Quarter Horse Association in thanking the RMTC for facilitating the recently completed research involving detection of ethylphenidate in race horses," said Dr. Glenn Blodgett, AQHA Past President and RMTC board member. "This study came about because AQHA identified abuse of this drug and the RMTC was capable of conducting tactical research of the drug in a timely manner."

Two other RMTC tactical research studies have recently received funding from The Jockey Club. 
  • "Selective Androgen Receptor Modulator LGD-4033 in the Horse," was designed for the identification and detection of the SARM LGD-4033 in horse urine, blood and hair. SARMs are anabolic steroid-like substances that have no therapeutic use in the racing horse. They are generally administered to improve performance and affect the outcome of a race. 
  • "Improved Detection of Erythropoiesis-Stimulating Agents," has focused on screening methodology for blood doping in the horse. Currently, there is a very limited window of time for detecting the administration of EPO-stimulating agents. This project will allow more sensitive screening, with a goal of increasing the ability of laboratories to detect these substances tenfold.
  • "Substances that have no therapeutic use in Thoroughbred racehorses are a real and immediate threat to our sport," said James L. Gagliano, president and chief operating officer, The Jockey Club. "The Jockey Club is proud to support research funded by the RMTC's Tactical Research Grant Program to help detect such substances."
