Bisphosphonates Ban: Keeneland, Fasig-Tipton and Ocala Breeders’ Sales Ban Off-Label Use of Popular Navicular Disease Medication in Young Thoroughbreds

Bisphosphonates are a type of medication used to treat osteoporosis in humans. They have been approved by the US Food and Drug Administration since 2014 for treatment of navicular disease in horses older than four. Research in Europe, conducted by Professor Jean-Marie Denoix and others, has also investigated the possible expanded use of one bisphosphonate, tiludronate (Tildren) for other lameness problems, such as bone spavin and osteoarthritic lesions of the thoracolumbar vertebral column. Professor Denoix also led the initial research on Tildren for navicular disease in older horses.
