Early in the process, a survey was sent to racetrack practitioners through the AAEP to determine which medications they felt were necessary to practice in a racing environment. That list was prioritized by the importance placed on the drugs by veterinarians and the frequency of positive drug violations. A number of the medications were removed as they were not available or no longer appropriate for use in horse racing (e.g., dipyrone and anabolic steroids). And some medications were added, such as firocoxib, because it was approved by the FDA for use in horses. The final list was developed by the SAC with further input from the AAEP, analytical chemists, veterinary pharmacologists, and regulatory veterinarians in conjunction with the RCI.
While the list is not inclusive of all potential medications that can be used in a horse, every effort was made to provide representative medications necessary to treat the common ailments of horses in training. Subsequent to the development of the initial list, additional medications have been added at the request of both the USTA and AAEP veterinarians. Furthermore, the RMTC has a formal process for considering additional medications for inclusion on the CTS list as new medications become available or as research funding becomes available.
