4.1 Target species

For cats and pet rabbits

4.2 Indications for use, specifying the target species

For the prevention and treatment of flea infestations on cats of 4 kg body weight and greater. For cats of less than 4 kg bodyweight use the appropriate Advantage product.

For the treatment of flea infestations on pet rabbits of 4 kg body weight and greater. For rabbits of less than 4 kg body weight use the appropriate Advantage product.

Fleas are killed within one day following treatment. One treatment prevents further flea infestation for three to four weeks on cats and up to one week on pet rabbits. The product can be used as part of a treatment strategy for the control of Flea Allergy Dermatitis (FAD) in cats where this has been previously diagnosed by a veterinary surgeon.

4.3 Contraindications

Do not treat unweaned kittens of less than 8 weeks of age.

Do not use on pet rabbits of less than 10 weeks of age.

Do not use in cases of hypersensitivity to the active substance or to any of the excipients.

4.4 Special warnings for each target species

There are no special warnings required for the target species.

4.5 Special precautions for use

i. Special precautions for use in animals

Care should be taken to avoid the contents of the tube coming into contact with the eyes or mouth of the user or recipient animal.

Do not allow recently treated animals to groom each other.

Any collar should be removed prior to application of the product. Prior to re-fitting the collar, the treated area should be visually assessed to ensure it is dry.

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

People with known hypersensitivity to Imidacloprid should avoid contact with the veterinary medicinal product.

This product contains benzyl alcohol and may cause sensitisation or transient skin reactions (for example irritation, tingling).

Avoid contact of the product with the skin, eyes and mouth. Do not massage the application site.

Do not eat, drink or smoke during application.

Wash off any skin contamination with soap and water.

If the product gets into eyes accidentally, the eyes should be thoroughly flushed with water.

If skin or eye irritation persists, obtain medical attention.

If the product is accidentally swallowed, obtain medical attention immediately.

Wash hands thoroughly after use.

After application do not stroke or groom animals until the application site is dry (typically within an hour or so).

iii. Other precautions

The solvent in this product may stain certain materials including leather, fabrics, plastics and finished surfaces. Allow the application site to dry before permitting contact with such materials.

4.6 Adverse reactions (frequency and seriousness)

The product is bitter tasting and salivation may occasionally occur if the animal licks the application site immediately after treatment. This is not a sign of intoxication and disappears within a few minutes without treatment (see also section 4.9 Amount to be administered and administration route).

In very rare occasions skin reactions such as hair loss, redness, itching and skin lesions may occur. Agitation has also been reported. Excessive salivation and nervous signs such as incoordination, tremors and depression have been reported exceptionally in cats.

Oral ingestion may result in other gastrointestinal signs (vomiting and diarrhoea), which have been observed very rarely based on postmarketing data.

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

- very common (more than 1 in 10 animals treated displaying adverse reaction(s))

- common (more than 1 but less than 10 animals in 100 animals treated) - uncommon (more than 1 but less than 10 animals in 1,000 animals treated)

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

4.7 Use during pregnancy, lactation or lay

No reproductive toxic effects have been observed in rats and no primary embryotoxic or teratogenic toxic effects have been observed during the studies on rats and rabbits. Studies on pregnant and lactating queens and does together with their offspring are limited. Evidence so far suggests that no adverse effects are to be expected in these animals.

4.8 Interaction with other medicinal products and other forms of interaction

No incompatibility has been observed between this product at twice the recommended dose and the following commonly used veterinary products: lufenuron, pyrantel and praziquantel (cats). The compatibility of the product was also demonstrated with a wide range of routine treatments under field conditions including vaccination.

4.9 Amount(s) to be administered and administration route

Dosage and Treatment Schedule

Cat & Pet Rabbit (kg body weight)	Product	Number of Tubes	mg/kg bw
4 and greater	Advantage 80 mg Spot-On Solution for Large Cats & Pet Rabbits	1 x 0.8 ml	Maximum of 20
Cats & Pet Rabbits of less than 4 kg body weight receive 1 tube of the appropriate Advantage product.

Treatment should be repeated after 4 weeks. Treatment of nursing queens controls flea infestations on both dam and offspring.

Fleas are killed within one day following treatment. One treatment prevents further flea infestation on cats for 3-4 weeks and on rabbits for up to one week. Should re-treatment become necessary earlier than 4 weeks, do not re-treat more frequently than weekly.

Re-infestation from emergence of new fleas in the environment may continue to occur for six weeks or longer after treatment is initiated. More than one treatment may therefore be required, depending on the level of fleas in the environment. To aid reduction in environmental challenge, the additional use of a suitable environmental treatment against adult fleas and their developing stages is recommended. In order to reduce further the environmental challenge, it is recommended that all dogs, cats and rabbits in the household are treated.

The product remains effective if the animal becomes wet, for example after exposure to heavy rain or after swimming. However, re-treatment may become necessary, depending on the presence of fleas in the environment. In these cases do not treat more frequently than once weekly.

Method of Administration

Remove one tube from the package. Hold tube in an upright position, twist and pull off cap. Use reversed cap to twist and remove seal from tube.

Administration to the Cat

Part the hair on the cat's neck at the base of the skull until the skin is visible.

Place the tip of the tube on the skin and squeeze firmly several times to empty the contents directly onto the skin.

Administration to the Rabbit

Part the hair on the rabbit’s neck at the base of the skull until the skin is visible.

Place the tip of the tube on the skin and squeeze firmly several times to empty the contents directly onto the skin.

All Species

Correct application will minimise the opportunity for the animal to lick off the product.

Apply only to undamaged skin. Do not allow recently treated animals to groom each other.

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

In cats, no adverse clinical signs were produced using doses of five times the therapeutic level for eight consecutive weeks.

In rabbits, no adverse clinical signs were seen using doses of up to 45 mg/kg body weight (4 times the therapeutic level) weekly for 4 consecutive weeks.

Poisoning following inadvertent oral uptake in either man or animals is unlikely. In this event, treatment should be symptomatic. There is no known specific antidote but administration of activated charcoal may be beneficial.

4.11 Withdrawal period(s)

Not applicable as Advantage Large Cats & Pet Rabbits is not indicated for the treatment of food producing animals.

Do not use in rabbits intended for human consumption.

5. PHARMACOLOGICAL PROPERTIES

Ectoparasiticide for topical use: ATC VetCode: QP53AX17

Imidacloprid, 1-(6-Chloro-3-pyridylmethyl)-N-nitro-imidazolidin-2ylideneamine is an ectoparasiticide belonging to a group of chloronicotinyl compounds. Chemically, it is more accurately described as a chloronicotinyl nitroguanidine.

5.1 Pharmacodynamic properties

Imidacloprid has a high affinity for the nicotinergic acetylcholine receptors in the post-synaptic region of the central nervous system (CNS). The ensuing inhibition of cholinergic transmission in insects results in paralysis and death. Due to the weak nature of the interaction with mammalian nicotinergic receptor sites and the postulated poor penetration through the blood/brain barrier in mammals, it has virtually no effect on the mammalian CNS. The minimal pharmacological activity in mammals is supported by safety studies involving systemic administration of sub-lethal doses to rabbits, mice and rats.

In recent studies, in addition to the adulticide flea efficacy of imidacloprid, a larvicidal flea efficacy in the surroundings of the treated cat has been demonstrated. Larval stages in the cat’s surroundings are killed following contact with a treated animal.

5.2 Pharmacokinetic particulars

Oral studies in the rat show imidacloprid to be absorbed rapidly from the gastro-intestinal tract. Almost complete absorption (95%) occurs within 48 hours. Peak plasma concentrations are observed within 2.5 hours following administration. Tissue distribution is also rapid with the lowest levels recorded in the brain. The active ingredient undergoes extensive metabolism with only 10-16% remaining as parent compound. Almost complete (96%) elimination occurs within 48 hours, approximately 75% being removed by the kidneys and 21% with the faeces.

The solution is indicated for cutaneous administration. Following topical application, the product is quickly distributed over the animal. Acute dermal studies in the rat and target animal overdose and serum kinetic studies have established that systemic absorption is very low, transient and not relevant for clinical efficacy. This has been further demonstrated by a study in which fleas were not killed after having fed on previously treated animals once the animal’s skin and fur had been cleaned of all active material.
