| What is the treatment of choice for Equine protozoal myeloencephalitis (EPM) | Navigator. |
| MOA – Structural analog of thiamine and competes with it for absorption into parasite | Amprolium. |
| Anticoccidial with bacteriostaic effect | Amprolium. |
| Anticoccidial that needs diluted | Amprolium. |
| Albon | Anticoccidial. |
