LEXINGTON, Ky. - The Association of Racing Commissioners International (RCI) Model Rules clearly prohibit the administration of multiple Non-Steroidal Anti-Inflammatory Drugs (NSAIDs).
Veterinarians who find it medically necessary to treat a horse with more than one approved NSAID should ensure that no more than one approved NSAID is present above the secondary regulatory threshold. The secondary thresholds scientifically correlate with a 48-hour withdrawal time.
The RCI Controlled Therapeutic Medication Schedule governs the use of a single approved NSAID and the recommended withdrawal times are provided as guidance to facilitate compliance with the regulatory threshold. No NSAIDs may be present above the primary thresholds, which correspond to withdrawal time guidance between 24 hours and 14 days.
