This year’s Belmont Stakes was the stage for American Pharoah to become the first Triple Crown winner since Affirmed in 1978. However, it also brought tragedy when Helwan had to be euthanized after suffering a broken left front cannon bone.
While a drug did not cause Helwan’s broken bone, the fact that this horse was racing for the first time on a drug called LASIX (Furosemide) has rekindled a debate on the use of controlled substances and performance enhancing drugs in horse racing.
