Chickens (broilers, pullets, layers and breeder hens), turkeys.
Indications for use, specifying the target species
In chickens (broilers, pullets, layers and breeder hens), turkeys:
Treatment of intestinal coccidiosis caused by Eimeria spp susceptible to amprolium.
Dosage and administration
Administration in drinking water.
In chickens (broilers, pullets, layers, and breeder hens) and turkeys, the posology is: 20 mg amprolium / kg body weight / day (equivalent to 0.5 mL of oral solution / 10 kg bodyweight/day) for 5 to 7 consecutive days.
For the preparation of medicated water, the body weight of the animals to be treated and their actual daily water consumption should be taken into account. Consumption may vary depending on factors like age, state of health, breed, and husbandry system. To provide the required amount of veterinary medicinal product in ml per litre drinking water the following calculation should be made:
0.05 mL of the product per kg bodyweight
x average bodyweight (kg) of the animals to be daily treated
x number of animals
____________________________________________________________________________________
= mL of oral solution/.... Litre of drinking water
Total water consumption (L) of the herd at the previous day
Sufficient access to the system of water supply should be available for the animals to be treated to ensure adequate water consumption. No other source of drinking water should be available during the medication period. Medicated drinking water should be replaced every 24 hours.
After the end of the medication period the water supply system should be cleaned appropriately to avoid intake of sub-therapeutic amounts of the active substance.
The veterinary medicinal product should not be used in contact with metal pipework or containers.
Withdrawal periods
Chickens and turkeys:
- Meat and offal: zero days
Eggs: zero days
Contra-indications, warnings, etc
Contraindications: None known
Special warnings for each target species:
As with any antiparasiticide, frequent and repeated use of an antiprotozoal agent of the same class can lead to resistance development.
In case of detection of lack of efficacy during treatment, communicate it to competent national authorities.
Special precautions for use
i) Special precautions for use in animals
The product is not intended for a preventive use.
This product should be reserved in case of coccidiosis outbreaks due to non-availability of vaccine, in case of lack of efficacy of vaccine and in vaccinated flocks if a severe coccidial challenge is diagnosed before immunity has fully developed.
ii) Special precautions to be taken by the person administering the medicinal product to animals
This product is acidic and may cause irritation to, or corrosion of, the skin, eyes, throat and airways.
Avoid all physical contact with the product, including any vapours.
Do not eat, drink or smoke whilst handling this product.
Wear impervious gloves and protective glasses when handling the product.
The selected protective gloves should satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.
In the case of contact with skin or eyes, wash the affected area with clean running water immediately and remove any contaminated clothes. If irritation persists, seek medical advice and show the label to the physician.
In case of accidental ingestion, rinse the mouth with fresh water, seek medical advice immediately and show the label to the physician
Those with known hypersensitivity to amprolium or to sorbic acid should avoid contact with the product.
Wash hands and exposed skin after use.
iii) Other precautions
Amprolium is classified as a persistent substance in soil.
Adverse reactions (frequency and seriousness)
None known.
Use during pregnancy, lactation or lay
Studies in laboratory animals have not produced any evidence of teratogenic effects. The safety of amprolium has not been investigated in laying birds. Use only according to the risk/benefit assessment by the responsible veterinarian.
Interaction with other medicinal products and other forms of interaction
Amprolium is an anticoccidial belonging to thiamin analogs family. Therefore, the efficacy of amprolium may be reduced during a simultaneous administration of products containing vitamin B-complex.
Overdose (symptoms, emergency procedures, antidotes), if necessary
A prolonged use at high doses can produce thiamine deficiency. This deficiency can be compensated by a thiamine intake.
Pharmaceutical precautions
PHARMACOLOGICAL PROPERTIES
Pharmacotherapeutic group: antiparasitic products, other antiprotozoal agents, amprolium.
ATCvet code: QP51AX09.
Pharmacodynamic properties
Amprolium is an anticoccidial which belongs to the thiamine analogues family. Amprolium acts by interfering as a competitive antagonist of thiamine within thiamine transport mechanisms. It interferes in the carbohydrate metabolism required for coccidies multiplication and survival.
In in-vitro studies it was shown that the uptake of thiamine by schizonts of Eimeria tenella and by host intestinal cells can occur through passive diffusion or by an active, energy-and pH-dependent process. Amprolium competitively inhibited both systems, however, the parasite was shown to be more sensitive to amprolium than the host.
As shown with Eimeria maxima inoculated chicken, the administration of Amprolium resulted in a proportion of morphologically abnormal macrogametes and oocysts which may be considered the reason for a reduced sporulation rate.
Pharmacokinetic particulars
Amprolium is weakly absorbed after oral administration. Maximum plasma drug concentration is reached 4 hours later.
Amprolium is excreted mainly via faeces.
Environmental properties
Amprolium is persistent in soil.
