The Fédération Equestre Internationale’s 2011 Equine Prohibited Substance List is in effect, as of April 4. The list will continue to show all substances added to or removed from the 2010 list and database until June 4.

The updated list, which was unanimously approved at the FEI General Assembly in Taipei last November, is accessible online.

Some of the most important changes affecting USEF members competing in FEI classes have been summarized below by USEF Drugs & Medications Chief Administrator, Dr. Stephen Schumacher:

Altrenogest  (Regumate®) – has been moved from the banned list to the Controlled Medications list for stallions and geldings. (This is a permitted substance in mares if a FEI medication form is filed.) 

Medroxyprogesterone, Cyclophenil, Deslorelin and Fulvestrant – all anti-estrogenic or progestogen substances that have been added to the Controlled Medications list and were previously not listed.

Acetazolamide – was not listed previously, and has now been added to the Controlled Medications list.

Levomethadone – this is a different version of a substance already on the Controlled Medications list (methadone).

Ziconotide – has been specifically added to the banned list.

Graeme Cooke, Director of the FEI Veterinary Department, said: “The fight against doping is one that all international federations are committed to, and the FEI is working tirelessly to come up with new ways to contribute to that fight in line with the joint recommendations produced by the commissions headed by Professor Arne Ljungqvist and Lord Stevens.”

The FEI continues to test for prohibited substances at its major events as part of the Clean Sport campaign.
