Abstract
There was no study on the prevalence of doping control of racehorses in Korea. The purpose of this study was to determine prohibited substances in horse races of a drugs testing program. Blood samples were taken from those 298,543 starters prior to racing and the that finished top 3 runners of each race and horses designated by the stewards shall be taken for collection of 91,482 urine samples for the purpose of post-race doping test in Seoul, Busan and Jeju Race Park between 2002 and 2013. Detection and measurement of prohibited substances were carried out by ELISA, GC/MS and LC/MS using standard methods at the Doping Control Center, Korea Racing Authority. Total 0.0030% of pre-races and total 0.0186% of post-races tested positive for prohibited substances. In pre- and post-race, caffeine and ketoprofen were the most detected prohibited substance respectively. We thought that characteristics of pharmacokinetics and pharmacodynamics of drugs resulted in different between plasma and urine. These substances have also been detected with other prohibited drugs suggesting that unintentional feeding or bedding may be the reason and groomers' confusion of candidate horses based by the stewards' research.
