Standardbred Racing Medication Rules

UPDATE: August 12, 2020. The USTA’s Harness Racing Medication Collaborative has formally re-submitted three proposed Model Rule modifications dealing with Clenbuterol, Betamethasome, and Methylprednisolone policy in standardbred racing only. The ARCI Scientific Advisory Group will meet to consider this matter on August 28, 2020.

BACKGROUND:

The ARCI Scientific Advisory Group has previously assessed clenbuterol  and reported to the Drug Testing Standards and Practices Committee in April, 2019 that different policies might be appropriate for different types of racing to ensure equine health without compromising the integrity of the contests.  At that time they opened the door to a 96-hour withdrawal time for clenbuterol but did not suggest or recommend adoption of the USTA proposed threshold, pending further review and information.   The same was true for Betamethasome.

    i have owned horses for approximately 40 years and never have any of my horses had a positive for any drugs. I have been in small mom and pop stables as well as very large stables at no time did I ever make suggestions to any trainers as to how to feed or medicate my horses. I honestly feel if you hire any professional to do a job then you should let then do the job. punishing an owner is counter productive to our sport, the owner after should have to move their horse or horses to a new barn. that would hurt the guilty party not the innocent owner or group of owners. Mandating the transfer of the horses would send a loud and clear message to cheaters.
