INDIANAPOLIS, IN—JUNE 6, 2018—Altrenogest (brand name Regu-Mate) is sold as an oral progestin used to suppress estrus in mares. Altrenogest is classified by the Association of Racing Commissioners International’s Uniform Classification Guidelines as a drug Class 4 and penalty Class C substance. 

Effective July 15, 2018, the Indiana Horse Racing Commission will impose penalties for any colt, gelding or stallion testing positive for Altrenogest. In conformation with ARCI guidelines, the use of Altrenogest in mares will be permitted.
