The newly approved medication rules will become effective August 1, 2015 and include the regulation of 16 additional therapeutic medications with threshold levels. Included are Acepromazine, Albuterol, Butorphanol, Clenbuterol, Dantrolene, Detomidine, Diclofenac, DMSO, Firocoxib, Glycopyrrolate, Lidocaine, Mepivacaine, Methocarbamol, Omeprazole, Procaine Penicillin, and Xylazine. The threshold levels and withdrawal guidelines were recommended by the Racing Medication and Testing Consortium and adopted by the Association of Racing Commissioners International.
The IRB recognizes that the use of corticosteroids in racehorses is controversial. However, when used responsibly, the medications can be beneficial. Accordingly, the IRB will implement a grace period to allow veterinarians time to adjust their veterinary practices and to allow trainers time to adjust their training practices. The thresholds levels for the following corticosteroids will become effective October 4, 2015.
Corticosteroid Recommended Withdrawal Guideline Betamethasone 7 days Dexamethasone 72 hours Isoflupredone 7 days Prednisolone 48 hours Triamcinolone Acetonide 7 days
Important Note: Methylprednisolone will remain a prohibited substance with no threshold level.
If a laboratory finding in your horse following a race indicates the presence of any of the therapeutic medications at a concentration that exceeds the threshold, you will be in violation of the IRB medication rules.
The Board’s laboratory is phasing out ELISA screening and begun instrumental screening. Instrumental screening (GC-MS or LC-MS instrumentation) offers increased sensitivity by lowering limits of detection, as compared to ELISA.
