Amprolium is an anticoccidial (coccidiostat) which belongs to the family of thiamine analogues. It acts by interfering as a competitive antagonist of thiamine (vitamin B1) within thiamine transport mechanisms of Eimeria spp. It affects carbohydrate metabolism required for coccidial multiplication and survival. Upon ingestion of amprolium, the coccidia experience thiamine deficiency and starve from malnutrition. Amprolium is rapidly eliminated (i.e. within hours), predominantly via faeces and to a lesser degree via urine.
Amprocox Oral is indicated for the treatment of intestinal coccidiosis caused by Eimeria spp. susceptible to amprolium in chickens (broilers, pullets, layers and breeder hens) and turkeys.
Do not use Amprocox Oral for preventive treatment.
