Decoquinate is a quinolone derivative that is used in the control of coccidiosis in domestic animals. Decoquinate treats and prevents coccidiosis in chickens, cattle, goats, sheep, etc. Decoquinate acts on sporozoites development and prevents their penetration of the gut epithelium. Decoquinate inhibits mitochondrial respiration and electron transport in Eimeria.

Diclazuril is a main component of veterinary drugs used for the treatment of coccidiosis (chickens, turkeys, rabbits, etc) and equine protozoal myeloencephalitis (horses). When used for the treatment of coccidiosis, it acts by causing the degeneration of schizonts and gamonts. While in the animals affected by protozoal myeloencephalitis the drug is believed to inhibit merozoite production. In vivo experiments on horses have shown that the drug may cross the blood brain barrier.

Toltrazuril (Baycox, Procox, Tolcox, Toltrazuril) is a veterinary drug approved in Europe for the treatment of parasitic infections caused by roundworms and coccidia. In dogs it is used in combination with emodepside (Procox).
