On 11 September the British Horseracing Authority (BHA) advised that the possession, use or administration of Regumate Equine could amount to breaches of the rules of Racing. This decision could have repercussions on other equestrian disciplines and the ban could be cascaded down to other sports including dressage, showjumping and eventing.
the British Horseracing Authority notice regarded the use of products – such as Regumate – which contain altrenogest, an oral synthetic progesterone / hormone. Their testing of Regumate Equine oral solution (MSD Animal Health) had detected the presence of Trendione which is an anabolic steroid. It is ‘Prohibited At All Times Substance’ under Schedule (G)1 of the BHA Rules of Racing.
The British Horseracing Authority therefore advised that the possession, use or administration of Regumate Equine could amount to breaches of the rules of Racing. They advise trainers and other industry participants to remove Regumate Equine from all licensed premises, and not to administer the product. Further advice may be sought by talking to your vet.
