Product properties


Each kilogram contains:

250 grams Amprolium (Hydrochloride) and 16 grams Ethopabate

Mechanism of Action:

Amprolium has a molecular structure very similar to that of Thiamine (vitamin B1) and by a competetive replacement procedure with this vitamin, disrupts the parasite’s metabolism and its first asexual reproduction phase. Amprolium is effective against schizonts as well as merozoites and to some extent against sexual reproduction phases (gametogony and sporogony).

Ethopabate replaces para aminobenzoic acid and by synthesis of   tetrahydrofolic acid, affects next phase of parasite’s asexual reproduction, thus exerting coccidiostat properties even against E. maxima and E. mivati which are resistant to Amprolium.

Indications of use

Ethoamprox® is effective against various species of Eimeria. It is used for prevention and control of coccidiosis in chickens (broilers, layers) and turkeys during their whole life.
