Amprolium is an anticoccidial drug. It has also been used for many years and needs no withdrawal time to guard against residue in the meat. It is given in the drinking water and interferes with metabolism of the vitamin thiamin (vitamin B1) in coccidia. Amprolium is quarternized derivative of pyrimidine which is a thiamine antagonist. It is most active against E. tenella, E. necatrix and E. acervulina and to lesser extent E. maxima. It could be fed at several times the recommended dose with no ill effects and probably, one of the safest anti-coccidial drugs to be used extensively. There is no premarketing withdrawal requirement for this compound.
