New California Horse Racing Board Rule 1867.1, which becomes effective July 1, prohibits the administration of bisphosphonates to any horse within a facility regulated by the CHRB and also prohibits any horse from entering the grounds that has been administered the drug within six months. This means that any horse administered bisphosphonates since January 1, 2020, will not be permitted within any CHRB-regulated facility (racetracks and training centers) within a six-month period of such administration.

Bisphosphonates inhibit the normal bone repair process, which is potentially dangerous for young horses racing and in training.Bisphosphonates are approved by the Food and Drug Administration for use in adult horses to treat navicular syndrome or similar foot pain.
