NEW YORK (AP) — Todd Pletcher and D. Wayne Lukas are among a group of high-profile horse trainers urging a gradual elimination of race-day medication in the United States. The group of mostly New York-based trainers joins many high-profile owners and breeders, the Jockey Club and other national racing organizations in calling for a ban on race-day use of Lasix, but the movement has been resisted by a majority of horsemen.
