Pharmacological properties

4.1 ATCvet code :

QP51BC03

4.2 Pharmacodynamics

Diclazuril is an anticoccidial of the benzeneacetonitrile group without antibacterial activity and has anticoccidial activity against Eimeria species. Depending on the coccidia species, diclazuril has a coccidiocidal effect on the asexual or sexual stages of the development cycle of the parasite. Diclazuril treatment will only have limited effect on the intestinal lesions caused by parasitic stages older than 16 days. Treatment with diclazuril causes interruption of the coccidial cycle and of excretion of oocysts for approximately 2 weeks. This allows the animal to bridge the period of decrease of maternal immunity (observed at approximately 4 weeks of age).

4.3 Pharmacokinetics

The absorption of diclazuril in lambs is poor after administration of the oral suspension. Maximum concentrations in plasma are reached about 24 hours after dosing. The absorption decreases with the animals’ age. The elimination half-life is about 30 hours. In-vitro studies on sheep hepatocytes demonstrated that metabolic transformation of diclazuril is limited. This was equally observed in other animal species. Excretion occurs almost completely via the faeces.

When diclazuril is administered in oral suspension to calves, its absorption is poor.

Environmental properties

Diclazuril has been shown to be very persistent in soil.

3

Target species

Cattle (calves) and sheep (lambs).

3

Indications

Cattle (calves):

Prophylaxis of coccidiosis caused by Eimeria bovis and Eimeria zuernii.

Sheep (lambs):

Prophylaxis of coccidiosis caused by Eimeria crandallis and Eimeria ovinoidalis.

Use the veterinary medicinal product during the prepatent period of infection for the prevention of clinical signs.

3

Dosage

Oral use.

Oral suspension to be administered at a dosage of 1 mg diclazuril per kg body weight i.e. 1 mL per 2.5 kg body weight in a single oral administration.

To ensure a correct dosage, body weight should be determined as accurately as possible.

Underdosing could result in ineffective use and may favour resistance development.

Method of administration:

Shake vigorously for 1 minute by repeatedly turning the bottle upside down by wrist action.

For the 5 L and 2.5 L back-pack bottles, use a drenching gun. Connect the drenching gun and draw-off tubing to the back-pack bottle as follows:

• Attach the open end of the draw-off tubing to an appropriate drenching gun.

• Attach draw-off tubing to the spigot cap that is included in the pack.

• Replace shipping cap with the spigot cap having the draw-off tubing. Tighten the spigot cap.

• Gently prime the drenching gun, checking for leaks.

• Follow the drenching gun manufacturer's directions for adjusting the dose and proper use and maintenance of the drenching gun and draw-off tubing.

• After using spigot cap, re-close container with the shipping cap.

For the 1 L and 250 mL bottles, to ensure a correct dosage, the use of either a syringe or an appropriate device for oral administration is necessary and the veterinary medicinal product should be administered directly in the mouth of the animal.

Contraindications

Do not use in cases of hypersensitivity to the active substance or to any of the excipient(s).

3

Adverse reactions

Cattle (calves) and sheep (lambs):

Very rare (<1 animal / 10 000 animals treated, including isolated reports):

Gastrointestinal signs (e.g. Diarrhea1,2);

Lethargy, Recumbency;

Agitation;

Neurological signs (e.g. Paresis)

1: with possible presence of blood

2: even though oocyst excretion is reduced to a very low level.

Reporting adverse events is important. It allows continuous safety monitoring of a veterinary medicinal product. Reports should be sent, preferably via a veterinarian, to either the marketing authorisation holder or its local representative or the national competent authority via the national reporting system. See the package leaflet for contact details.

Warnings

Special precautions for safe use in the target species:

Not for use for group treatment.

This veterinary medicinal product should only be used in a restricted number of animals at high risk of infection, i.e. animals kept in the same restricted, contaminated environment.

Animals to be treated should be separated and moved to dry and clean areas. When a drenching gun is used to administer the product, care must be taken to avoid damage to the pharyngeal region.

Special precautions to be taken by the person administering the veterinary medicinal product to animals:

Esters of parahydroxybenzoic acid may cause allergic reactions (possibly delayed). People with known hypersensitivity to parabens should administer the veterinary medicinal product with caution.

Wash hands after administration of the veterinary medicinal product.

Special precautions for the protection of the environment:

Not applicable.

3.11 Special restrictions for use and special conditions for use, including restrictions on the use of antimicrobial and antiparasitic veterinary medicinal products in order to limit the risk of development of resistance

Not applicable.

3

Use during pregnancy, lactation or lay

Not applicable.

3

Interactions

None known.

3

Overdose

Cattle (calves):

No signs of overdose were noted after a single administration of 5 times the recommended dose. In case of repeated administration of 3 to 5 times the dose, on 3 consecutive days, a softening and a colour change (dark brown) of the faeces can be observed in some calves. These observations were transient and disappeared without specific treatment.

Sheep (lambs):

No signs of overdose were noted after administration of 5 times the recommended dose.

3

Special warnings

In certain cases, only a transient reduction of oocyst shedding may be achieved. If there is no recent and confirmed history of clinical coccidiosis, the presence of the disease in the flock or herd should be confirmed by faecal sampling prior to treatment.

The preferred timing of treatment is directed by the known epidemiology of Eimeria spp. with treatment being most effective during the pre-patent phase of the infection before clinical signs occur.

Coccidiosis is an indicator of insufficient hygiene in the flock/pen. It is recommended to improve hygiene and to treat all calves in a pen and all lambs in a group. This will contribute to reduce the infection pressure and assure a better epidemiological control of the coccidiosis infection.

Repeated use for an extended period, particularly when using the same class of substances, increases the risk of resistance development. The decision to use the product should be based on confirmation of the coccidian species and burden, or of the risk of infection based on its epidemiological features, for each herd/flock. Unnecessary use of antiprotozoals or use deviating from the instructions given in the SPC may increase the resistance selection pressure and lead to reduced efficacy. Cross-resistance between toltrazuril and diclazuril is possible and should be investigated. Use of diclazuril should be carefully considered when susceptibility testing has shown resistance to triazine-derivates because its effectiveness may be reduced.

It is recommended to further investigate cases of suspected resistance, using an appropriate diagnostic method (e.g. faecal oocyst count reduction test). Confirmed resistance should be reported to the marketing authorisation holder or to the competent authorities. If resistance is present, it should be considered to use an antiprotozoal from another class/with a different mechanism of action.

Use of the product should be based on identification and susceptibility testing of the target pathogens. If this is not possible, therapy should be based on epidemiological information and knowledge of susceptibility of the target pathogens at farm level, or at local/regional level.

Use of the product should be in accordance with official, national and regional antimicrobial policies.

The veterinary medicinal product should not be used as part of herd health programmes.

To alter the course of an established clinical coccidial infection, in individual animals already showing signs of diarrhoea, additional supportive therapy is required.
