The use of agents that elevate the horse’s TCO2 (total carbon dioxide) level above those existing naturally in the untreated horse at normal physiological concentrations is prohibited. In Massachusetts, the regulatory threshold for TCO2 is 37.0 millimoles per liter of plasma/serum.
Massachusetts regulations permit certain non-steroidal anti-inflammatory medications (“NSAIDs”) to be used in racehorses under the following conditions:
The use of all but one of the approved NSAIDs (phenylbutazone, flunixin, or ketofen) shall be discontinued at least 48 hours before the post time for the race in which the horse is entered. No NSAID shall be administered within 24 hours of such post time.
Any horse to which a NSAID has been administered is subject to having a blood and/or urine sample(s) taken to determine the quantitative NSAID level(s) and/or the presence of other drugs which may be present in the blood or urine sample(s).
The Massachusetts Gaming Commission has adopted the Association of Racing Commissioners International’s Controlled Therapeutic Substance rule, which utilizes thresholds which may be found here.
