Applications: Coccidiosis

Toltrazuril is highly effective against all coccidial intracellular stages (shizogony & gametogony) of all important Eimeria species. Anticoc Vet (Toltrazuril) causes the following cidal changes in the organelles of the parasite at multiple levels. 

 Cytoplasma vacuolization and enlarged endoplasmic reticulum. 

 Swollen mitochondria.

 Interference with nuclear division. 

 Damage (bursting) of type II wall-forming bodies in macrogamets. 


 With medicine: Toltrazuril is compatible with antibiotics such as enrofloxacin, ampicillin, tetracycline, tiamulin and tylosin. With food & others: Not known. 

Toltrazuril appears to be well tolerated in birds. An adverse effect profile in
mammals is not well described. Potentially, GI signs could occur. Some horses
receiving the related drug ponazuril, developed blisters on their nose and
mouth, and some, a rash or hives during field trials.

Very limited information is available. Doses of up to 10X in horses were
tolerated without significant adverse effects. 5X overdoses in poultry have
been tolerated without clinical signs noted. Decreased water intake has been
seen if overdoses are greater than 5X.

 Poultry: Meat- 8 days, Egg- Should not be used in laying birds producing eggs for human consumption. 

Ruminants & Pigs: Meat- 77 days, Milk- Should not be used in lactating animals producing milk for human consumption.
