The Fédération Equestre Internationale has approved changes to its Prohibited Substances List – the new list goes into effect January 1, 2014.
Two controlled substances have been added to the list: Metformin, a potent, but legitimate oral anti-diabetic drug with a potential welfare risk; and Levothyroxine, an exogenous thyroid hormone replacement that could enhance performance.
Currently a banned substance, Adrenocortico-trophic hormone (ACTH), will be moved to the Controlled Medication section of the 2014 list due to its therapeutic value.
Three previously unlisted substances – Ammonium Chloride injectable, Gamma-Butyrolactone (GBL) and Gamma-Hydroxybutyrate (GHB) – will be added to the Banned Substances section for 2014, as they are considered to have a potential for abuse, or to improve athletic performance.
The changes to the FEI Equine Prohibited Substances List are also accessible on the FEI Clean Sport webpage. The FEI Equine Prohibited Substances Database will be amended and the complete 2014 Equine Prohibited Substances List will be made available on the Clean Sport website prior to the new year.
