Trainer Mike Natale received a $500 fine and a 15-day suspension after one of his horses tested positive for an antihistamine known as tripelennamine at Prairie Meadows. The horse, Frozen Angel, was disqualified from his second-place finish in the eighth race on May 3, and the purse ordered forfeited.
Tripelennamine is classified as a Class 3 substance, one that may have generally accepted medical use, but that has potential to affect performance.
Natale denied using the substance on the horse.
