Nebraska-based trainer David C. Anderson has been suspended indefinitely by the Iowa Board of Stewards because his homebred horse Reach One More tested positive for oxymorphone, a painkiller, following his victory in the Iowa Stallion Stakes on Aug. 1. On Aug. 14, the stewards received a report from Iowa State University stating Reach One More's post-race sample contained oxymorphone. Anderson sent his split sample to Louisiana State University. On Aug. 31, the LSU laboratory confirmed the presence of oxymorphone in Reach One More's sample. Oxymorphone, marketed most commonly under the names Numorphan and Opana, is a powerful opioid analgesic considered approximately six to eight times more powerful than morphine. It was introduced to the United States market in 1959. Reach One More, a 3-year-old gray gelding, has won six stakes races in a row and 7 of 8 races lifetime for earnings of $123,981. His victory in the Iowa Stallion Stakes, at which Anderson was in attendance, was his first race outside of Nebraska and his most valuable win, as he earned $49,761.
