Wednesday, February 13, 2013Veterinarians have been treating equine protozoal myeloencephalitis (EPM) with ponazuril (Marquis) since the Food and Drug Administration approved the antiprotozoal in 2001 but, as with any pharmaceutical approach to disease, fine-tuning an effective treatment protocol is always a work in progress. In laboratory studies scientists have shown ponazuril mus...
