The drug has a persistent action and protects cattle for certain duration against infection or re-infection with the following parasites for the period indicated:

Species Protection period (days)

Dictyocaulus viviparus 120

Ostertagia ostertagi 120

Haemonchus placei 90

Oesophagostomum radiatum 150

Trichostrongylus axei 90

Linognathus vituli 133

The product is effective against Hypoderma larvae at the time of treatment but its persistent activity against Hypoderma has not been evaluated.

If the product is given before the end of the fly season complimentary treatment with a product effective against Hypoderma may be required.

Persistent efficacy periods have not been established for parasite species other than those included in the above list. Therefore, re-infection of animals on pasture contaminated by parasites other than these remains possible before the end of the 90 day minimum persistency period demonstrated for specific species.

4.3 Contraindications

Do not use in animals less than 100 kg bodyweight or greater than 500 kg.

Do not inject the product by intravascular route. Intravascular injection may result in ataxia, paralysis, convulsions, collapse and death. To prevent any intravascular injection, carefully follow the administration procedure described in item “Amounts to be administered and administration route”.

4.4 Special warnings

“Care should be taken to avoid the following practices, because they increase the risk of development of resistance and could ultimately result in ineffective therapy:

Too frequent and repeated use of anthelmintics from the same class, over an extended period of time;

Under-dosing which may due to underestimation of body weight, misadministration of the product, or lack of calibration of the dosing device (If any).

Suspected clinical cases of resistance to anthelmintics should be further investigated using appropriate tests (e.g. Faecal Egg Count Reduction Test).Where the results of the test(s) strongly suggest resistance to a particular anthelmintic, an anthelmintic belonging to another pharmacological class and having a different mode of action should be used.”

4.5 Special precautions for use

Special precautions for use in animals

In order to prevent abscesses, a strict aseptic technique is recommended.

CYDECTIN 10% LA for Cattle has been formulated specifically for subcutaneous injection in dorsal surface of the ear of cattle and must not be given by any other route of administration or to any other species.

To avoid possible secondary reactions by the death of Hypoderma larvae in the spine or the oesophagus of animals, it is recommended to administer a product effective against Hypoderma larvae after the end of fly activity and before the larvae reach their resting sites. Consult your veterinary surgeon on the correct timing of this treatment.

Immunity to nematodes depends on adequate exposure to infection. Although not normally the case, circumstances could occur in which anthelmintic control measures might increase the vulnerability of cattle to re-infection. Animals may be at risk towards the end of their first grazing season, particularly if the season is long, or in the following year if they move onto heavily contaminated pasture. In such instances, further control measures may be necessary.

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

Avoid direct contact with skin and eyes.

Wash hands after use.

Do not smoke, drink or eat while handling the product.

Take care to avoid self-injection. Advice to Medical Practitioners in case of accidental self injection: Treat symptomatically.

4.6 Adverse reactions (frequency and seriousness)

On rare occasions, immediate or delayed swelling can be observed at the injection site, these swellings may further develop into abcesses (approx. 1% of cases). The frequency of injection site swellings tends to be higher in the heavier animals. These side effects generally disappear without treatment , within 14 days after administration, some may persist for up to 5 weeks in a number of animals (<5%) and in very rare occasions longer.

On rare occasions, depression and ataxia can be observed after injection.

In case of hypersensitivity reactions, a symptomatic treatment should be applied.

The frequency of adverse reactions is defined using the following convention:

- very common (more than 1 in 10 animals displaying adverse reactions during the course of one

treatment)

- common (more than 1 but less than 10 animals in 100 animals)

- uncommon (more than 1 but less than 10 animals in 1,000 animals)

- rare (more than 1 but less than 10 animals in 10,000 animals)

- very rare (less than 1 animal in 10,000 animals, including isolated reports).

4.7 Use during pregnancy, lactation or lay

Can be used during pregnancy. However, note 4.3. Contra-Indications.

4.8 Interaction with other medicinal products and other forms of interaction

The effects of GABA agonists are increased by moxidectin.

4.9 Amounts to be administered and administration route

Dosage is 0.5 ml/50 kg bodyweight, equivalent to 1.0 mg moxidectin/kg bodyweight, given by a single subcutaneous injection in the ear using an 18 gauge, 25 – 40 mm hypodermic needle. The 50ml vial stoppers must not be broached more than 20 times. Use automatic syringe equipment for the 200 ml vial.

Shake well before use

To ensure administration of a correct dosage, body weight should be determined as accurately as possible; accuracy of the dosing should be checked

The injection should be given subcutaneously in the loose tissues on the dorsal surface of the ear, just distal to the distal edge of the auricular cartilage.

The dorsal (outer) surface of the ear should first be cleansed with antiseptic and allowed to briefly air dry. Palpate the edge of of the auricular cartilage closest to the head, on the dorsal (hairy) surface of the ear. From this landmark, taking care to avoid blood vessels (artery,vein), the needle should be inserted subcutaneously starting at a point approximately 3 to 3.5 cm distal to this edge (away from the head), and directed towards the base of the ear, and the needle advanced to the hub. At this point, gently aspirate the syringe to confirm that the needle is not in a blood vessel.

Upon injection, the resulting depot should reside just distal to the edge of the auricular cartilage.

Following administration, the needle is withdrawn from the skin as pressure is applied for several seconds with the thumb at the point of insertion.

Due to the long lasting protection against Dictyocaulus viviparus and the stomach worms, Ostertagia ostertagi and Haemonchus placei, a single treatment with the formulation at turn-out helps control parasitic bronchitis (lungworm) and parasitic gastro-enteritis throughout the grazing season by reducing the build-up of infective larvae on pasture associated with these parasites. For best results the injection should be given to each calf of target weight to be grazed together immediately prior to being turned out to pasture. Animals should be set stocked throughout the grazing season or moved to a pasture which has not been grazed by other cattle earlier in the season.

Diagram: Ear injection procedure

• Use one hand to grasp and steady the ear.

• Inject subcutaneously using an 18 gauge x 1 inch needle.

• Inject contents. Depot should be just distal to the distal edge of the auricular cartilage.

• Apply pressure at the point of insertion as the needle is withdrawn from the skin to help seal the opening.

4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary

Reactions at the injection site have to be expected more frequently and severe depending on the injected volume. Systemic signs of overdoses are consistent with the mode of action of moxidectin. These signs are manifested as transient salivation, depression, drowsiness and ataxia 24 to 36 hours post-treatment. The systemic signs usually disappear within 36 to 72 hours without treatment. At doses >3 times the recommended dose divided on both ears, the systemic signs included recumbency, muscle tremor, ruminal tympany and dehydration, which were resolved after treatment with fluids. The systemic signs can last for a few days to ten days. There is no specific antidote.

4.11 Withdrawal period(s)

Meat and offal: 108 days.

Milk: Not permitted for use in lactating animals producing milk for human consumption or industrial purposes or within 80 days of expected parturition.

The withdrawal period is based solely on a single injection at the ear site of injection.

5. PHARMACOLOGICAL PROPERTIES

ATCvet Code QP54AB02

‘Pharmacotherapeutic group: Endectocides’

5.1 Pharmacodynamic properties

Moxidectin is an endectocide active against a wide range of internal and external parasites and is a second generation macrocyclic lactone of the milbemycin family.

Moxidectin interacts with GABA receptors and chloride channels.

The net effect is to open the chloride channels on the postsynaptic junction to allow the inflow of chloride ions and induce an irreversible resting state. This results in flaccid paralysis and eventual death of parasites exposed to the drug.

5.2 Pharmacokinetic particulars

Moxidectin is absorbed following subcutaneous injection with maximum blood concentrations being achieved 24 to 48 hours post injection. The drug is distributed throughout the body tissues but due to its lipophilicity it is concentrated mainly in the fat. The depletion half life in fat is 26 – 32 days.

Moxidectin undergoes limited biotransformation by hydroxylation in the body. The only significant route of excretion is the faeces.
