The Maryland Thoroughbred Horsemen's Association issued the following statement to its members Tuesday:
“Effective immediately, horsemen are urged to discontinue the use of any and all adjunct bleeder medications for horses in training, including in particular, aminocaproic acid–commonly called Amicar.
Amicar and several other adjunct bleeder medications were placed on the Prohibited List in 2013 under the Association of Racing Commissioners International Uniform Classification Guidelines for Foreign Substances and Recommended Penalties Model Code and the National Uniform Medication Program. Aminocaproic acid, for example is a Class 4 substance and penalty Class C.
“It is important to understand that these medications cannot be regulated by withdrawal time guidance and/or a testing threshold and their use, no matter how far in advance of a race, may trigger a positive post-race test.
“Any trainer who chooses to continue the use of these medications for training in the future will run the risk of a post-race positive test.”
