Marquis (Ponazuril) Oral Paste is an effective treatment option for horses diagnosed with equine protozoal myeloencephalitis (EPM). This oral paste is formulated specifically to kill the parasite that causes EPM, known as sarcocystis neurona, and is even able to reach the central nervous system. To completely clear the illness, it's recommended to administer Marquis over the course of a 28-day treatment regimen. This antiprotozoal horse medication is sold in 127g tubes.How it Works

Marquis contains an active ingredient called ponazuril, which fights against several life stages of parasites. It passes the blood/brain barrier, then reaches the horse's CNS (central nervous system), where it effectively kills parasites.
