The substances that will be banned from 1 January 2012 are magnesium sulphate injections and any use of adrenocorticotropic hormone (ACTH). 17-alpha-hydroxy progesterone.
The drug is used to assist pregnancy, but works as an anabolic steroid in the male, and is also banned.
FEI veterinary director Graeme Cooke told H&H: “The two substances have no legitimate common usage in the horse. In theory [the changes] will not affect many.”
Valerenic acid has been removed from the banned substance category to the controlled medications list, meaning it can be used but not in competition.
