A group of prominent American horse racing organizations and tracks — including Baltimore’s Pimlico Race Course, site of the Preakness stakes — pledged Thursday to begin phasing out the use of Lasix, an anti-bleeding medication critics say is overused.
Tracks signing onto the initiative include Churchill Downs and Belmont Park, hosts of the Kentucky Derby and Belmont Stakes, respectively. Along with the Preakness, those events form the sport’s prestigious Triple Crown.
Also joining is Maryland’s Laurel Park, which — like Pimlico — is owned by The Stronach Group, a Canadian horse racing conglomerate.
