FEI announces changes to Equine Prohibited Substances List
FEI Bureau has approved the changes proposed by the FEI List Group

The Fédération Equestre Internationale (FEI) Bureau has approved changes to the Equine Prohibited Substances List proposed by its List Group. The new prohibited substances list will come into effect on January 1, 2014.

Previously unlisted Metformin, a potent but legitimate oral anti-diabetic drug with a potential welfare risk, has been added to the Controlled Medication list.

Levothyroxine, an exogenous thyroid hormone replacement that could enhance performance, has also been added to the Controlled Medication list after having been unlisted.

Adrenocortico-trophic hormone (ACTH) will be moved from Banned Substances to the Controlled Medication section for the 2014 list, due to its therapeutic value in equine medicine.

Three previously unlisted substances will be added to the Banned Substances section of the 2014 list .

Ammonium Chloride injectable, Gamma Butyrolactone (GBL) and Gamma-Hydroxybutyrate (GHB) are considered to have the potential for abuse to improve athletic performance.

The approved changes to the list are also accessible on the FEI Clean Sport webpage.

The FEI Equine Prohibited Substances Database will be amended and the complete 2014 list will be made available on the Clean Sport website prior to January 1, 2014.

Conforming with FEI rules, all changes to the list are published 90 days prior to implementation to allow National Federations, athletes and veterinarians sufficient time to familiarise themselves with the revised list.
