{Louisville, Kentucky}...The Senate Commerce Committee, chaired by Senator Jay Rockefeller, D.-W.Va., will have a hearing at 2:30 P.M. Thursday on "Medication and Performance Enhancing Drugs in Horse Racing." The Kentucky Horse Racing Commission said Wednesday that no traces of the powerful painkiller dermorphin were found in samples taken from horses running in this year's Kentucky Derby. The Association of Racing Commissioners International lists dermorphin among the most harmful substances that might be given to horses, and regulators say the drug has no legitimate use in horses. Dermorphin is a substance more powerful than morphine. The announcement follows a story by The New York Times that says Derby and Preakness winner I'll Have Another was treated with painkillers before the Belmont Stakes, but does not name the drug. The colt was retired from racing the day before the Belmont.
