Amprolium HCl                                           300       mg



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, E. acervuline, E. praecox 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.



VETKO AMPROVET 30% WSP is used as a preventive or therapeutic agent against Eimeria infections in poultry, especially E. tenella, E. necatrix, E. acervulina and E. praecox. It is effective against other protozoal infections like Histomoniasis (Blackhead) in turkeys and poultry; against coccidiosis in calves, sheep and goats; against amaebiasis in various species.
