With the Breeders' Cup in November at Del Mar, the organization released a statement today reminding horsemen of several important factors that could disrupt their chances at a championship should they not follow them. 

The new Breeders' Cup Condition of Entry will be in full effect. No Lasix will be permitted in the 48 hours preceding all races at Del Mar on November 5th and 6th. Pre-entry for races open October 1st online and closes at noon Pacific Time Monday, October 25th. 

Additional drug regulations include the following:

  • Intra-articular corticosteroid treatments are prohibited within 14 days of racing. A horse may not enter if it has received intra-articular corticosteroid injections in the fetlock joints within the previous 30 days immediately preceding the race. All corticosteroids in a post-race test sample are prohibited.

  • There is a 30 day cutoff date for extracorporeal shock wave therapy. Any horse that has been treated with the therapy in the 30 days prior to race day will be in violation of the Breeders' Cup condition of entry and will be ineligible to participate.

  • Non-steroidal anti-inflammatory drugs (NSAIDs) are prohibited within 48 hours of a work or a race. There is no authorized threshold for NSAIDs. 

  • In California, there is no permitted threshold for Clenbuterol and its use is restricted. Horses shipping to California are advised to stop all Clenbuterol treatments at a minimum of six weeks prior to race day. Pre-entry testing is available. 

  • CHRB Rule 1867.1 prohibits the use of Bisphosphonates. They may not be administered to any horse within a CHRB inclosure. No licensee shall bring into a CHRB inclosure a horse known to have been administered a bisphosphonate within the previous six months.
