Description: Amprolium is a coccidiostat (antiprotozoal) used for the treatment and prevention of coccidiosis in calves, sheep, goats, chickens (broilers and breeders) and other fowl such as turkeys, with activity against Eimeria spp, especially Eimeria tenella and Eimeria necatrix. It is a thiamine (vitamin B1) analogue and its pharmacological effect relies on competitive inhibition of thiamine uptake. Amprolium competitively inhibits the active transport of thiamine in isolated second-generation schizonts of Eimeria spp. and in host intestinal cells. Upon ingestion of Amprolium, the coccidia experience thiamine deficiency and starve from malnutrition.
