Six-year-old Moonlit Path tested positive for a banned substance that
prevents hemorrhaging after a sixth-place finish on her debut February
Trainer Nicky Henderson has been charged with breaching two rules by the British Horseracing Authority.
The queen's racing manager, Michael Oswald, described
it as "very disappointing news" and told British media that the monarch
had been informed.
The BHA said Henderson was responsible for the horse
being given tranexamic acid "with the intention of affecting her racing
performance or in the knowledge that her racing performance could be
affected by such."
A hearing is set to be held in June.
Henderson acknowledged the use of the substance, but said it was not used as doping.
"The substance concerned was administered by my vet
entirely in the interests of the horse's welfare, which is always
paramount," Henderson said. "There was no intention to enhance
performance and it is worth pointing out that we won the race in
question with the odds-on Ravello Bay."
Moonlit Path has run twice since her debt, finishing fourth of 13 on both occasions.
