Pharmacological action of
Stop coccid belongs to the antiaccidia group of the triazintrione group.
Toltrazuril, which is part of the drug, has a wide spectrum of coccidiocidal action at the stages of intracellular development of parasites, is effective against all types of coccidia, including Eimeria spp., Isospora spp., Cistoisospora spp., parasitizing in piglets, calves, lambs, rabbits, puppies of dogs and fur animals.
Toltrazuril has a damaging effect on mitochondria and the processes of fission of the coccidia nucleus, disrupting the formation of macrogametocytes, blocking respiratory enzymes, and causing death of parasites.
After oral administration of the drug, toltrazuril is slowly absorbed and has a coccidiocidal effect on the mucous and submucous membranes of the gastrointestinal tract.
In the body, toltrazuril is metabolized by sulfoxidation and hydroxylation, with the formation of sulfoxide and sulfone.
It is excreted mainly in an unchanged form – up to 70%, as well as in the form of metabolites with feces and partially with urine.
Stop coccid according to the degree of exposure to the body refers to low-hazard substances (hazard class 4 according to GOST 12.1.007-76), in recommended doses, it does not cause side effects and complications in animals, does not prevent the formation of immunity to coccidiosis.
Stop coccid is given to calves, lambs, kids, piglets, rabbits, puppies and fur animals for the treatment and prevention of coccidiosis.
Contraindication to the use of Stop Coccid is an increased individual sensitivity of the animal to the components of the drug, serious impairment of liver and / or kidney function.
Do not use the drug in adult ruminants with advanced cicatricial digestion.
Stop coccid in 1 ml contains toltrazuril – 50 mg as an active ingredient, as well as excipients: sodium benzoate, potassium sorbate, croscarmellose sodium, aspartic acid C 200, lactose, tween-80, aerosil, propylene glycol, xanthan gum citric acid Dimethicone and purified water.
Dosage and administration
Stop coccid is administered individually to animals orally with a dosing syringe or mixed with a small amount of feed. In case of sediment, the container with suspension should be thoroughly shaken before use.

In coccidiosis dysfunctional farms to achieve the maximum preventive effect reduce the number of oocysts secreted into the environment, the drug should be prescribed to susceptible animals until the first clinical signs of the disease appear in the herd.
With an overdose of the drug, an animal may experience a decrease in appetite, a decrease in water intake, an upset gastrointestinal tract, and vomiting.
Store the drug in the manufacturerÐ²Ðâ¢s sealed packaging, in a place protected from direct sunlight, separate from food and feed at temperatures from 0 ° C to 25 ° C.
