Grey, odour free collar.


4. CLINICAL PARTICULARS


4.1 Target species


Cats


4.2 Indications for use, specifying the target species


For the treatment and prevention of flea (Ctenocephalides felis)infestation for 7 to 8 months.

Protects the animal’s immediate surroundings against flea larvae development for 10 weeks.

Seresto can be used as part of a treatment strategy for the control of Flea Allergy Dermatitis (FAD).


The product has persistent acaricidal (killing) efficacy (Ixodes ricinus, Rhipicephalus turanicus) and repellent (anti-feeding) efficacy against tick infestations (Ixodes ricinus) for 8 months. It is effective against larvae, nymphs and adult ticks.

Ticks already on the cat prior to treatment may not be killed within 48 hours after collar application and may remain attached and visible. Therefore removal of ticks already on the cat at the time of application is recommended. The prevention of infestations with new ticks starts within two days after application of the collar.


4.3 Contraindications


Do not treat kittens less than 10 weeks of age.

Do not use in case of hypersensitivity to the active substances or to any of the excipients.


4.4 Special warnings for each target species


Ticks will be killed and fall off the host within 24 to 48 hours after infestation without having had a blood meal, as a rule. An attachment of single ticks after treatment cannot be excluded. For this reason, a transmission of infectious diseases by ticks cannot be completely excluded if conditions are unfavourable.

Ideally, the collar should be applied before the beginning of the flea or tick season.


As in all longterm topical products, periods of excessive seasonal hair shedding may lead to transient slight reduction of efficacy by loss of hair-bound portions of the active ingredients. Replenishment from the collar starts immediately so that full efficacy will be re-established without any additional treatment or collar replacement.

For optimum control of flea problems in heavily infested households it may be necessary to treat the environment with a suitable insecticide.


The product is water resistant; it remains effective if the animal becomes wet. However, prolonged, intense exposure to water or extensive shampooing should be avoided as the duration of activity may be reduced. Studies show that monthly shampooing or water immersion does not significantly shorten the 8 months efficacy duration for ticks after redistribution of the active substances in the coat whereas the product’s flea efficacy gradually decreased, starting in the 5th month.


4.5 Special precautions for use


Special precautions for use in animals


Not applicable.


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


Keep the bag with the collar in the outer packaging until use.

As with any veterinary medicinal products, do not allow small children to play with the collar, or to put it into their mouths. Pets wearing the collar should not be allowed to sleep in the same bed as their owners, especially children.

People with known hypersensitivity to the ingredients of the collar should avoid contact with the veterinary medicinal product.

Immediately dispose of any remnants or cut-offs of the collar (see section 4.9).

Wash hands with cold water after fitting the collar.


4.6 Adverse reactions (frequency and seriousness)


In rare cases mild behavioural disorders that may include scratching at the application site may be observed in animals that are not used to wearing collars on the first few days after fitting.Ensure that the collar is not fitted too tightly.

Mild application site reactions such as pruritus, erythema and hair loss may occur. These have been reported as uncommon and usually resolve within 1 to 2 weeks without the need for collar removal.

In single cases, a temporary collar removal may be recommended until the symptoms have disappeared.

In rare cases, application site reactions such as dermatitis, inflammation, eczema or lesions may occur and in these instances, collar removal is recommended.

Also in rare cases, slight and transient reactions as depression, change of food intake, salivation, vomiting and diarrhoea might occur initially. As in other topical applications, allergic contact dermatitis might occur in hypersensitive animals.


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

very common (affects more than 1 animal in 10)

common (affects 1 to 10 animals in 100)

uncommon (affects 1 to 10 animals in 1,000)

rare (affects 1 to 10 animals in 10,000)

very rare (affects less than 1 animals in 10,000)


4.7 Use during pregnancy, lactation or lay


Laboratory studies with either flumethrin or imidacloprid in rats and rabbits have not produced any effects on fertility or reproduction and showed no teratogenic, or foetotoxic effects. However, the safety of the veterinary medicinal product has not been established in target animals during pregnancy and lactation and in the absence of available data, the product is therefore not recommended in pregnant and lactating queens.


4.8 Interaction with other medicinal products and other forms of interaction


None known.


4.9 Amounts to be administered and administration route


Cutaneous use. One collar per animal to be fastened around the neck.

Cats receive one collar of 38 cm length.

For external use only.


Remove collar from protective bag directly before use. Unroll collar and make sure that there are no remnants from the plastic connectors inside the collar. Adjust the collar around the animal's neck without tightening it too tight (as a guide, it should be possible to insert 2 fingers between the collar and the neck). Pull excess collar through the loop and cut off any excess length extending beyond 2 cm.

The collar should be worn continuously for the 8 month protection period and should be removed after the treatment period. Check periodically and adjust fit if necessary, especially when kittens are rapidly growing.


This collar is designed with a safety-closure mechanism. In the unlikely event of a cat being trapped, the cats own strength is sufficient to widen the collar to allow for quick release.


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


Due to the nature of the collar overdosage is unlikely and signs of overdosage are not to be expected.

An overdosage of 5 collars around the neck wasinvestigated in adult cats for an 8 months period and in 10 week old kittens for a 6 months period and no other adverse effects were observed than already described in section 4.6.

In the unlikely event of the animal eating the collar mild gastrointestinal symptoms (e.g. loose stool) may occur.


4.11 Withdrawal period(s)


Not applicable.


5. PHARMACOLOGICAL PROPERTIES


Pharmacotherapeutic group: ectoparasiticides, insecticides and repellents, pyrethrins and pyrethroids, Flumethrin combinations

ATCvet code: QP53AC55


5.1 Pharmacodynamic properties


Imidaclopridis an ectoparasiticide belonging to the chloronicotinyl group of compounds. Chemically, it can be classified as a chloronicotinyl nitroguanidine. Imidacloprid is active against larval flea stages, adult fleas and lice. Activity against C.felisstarts immediately after application of the collar.

In addition to the indications listed under section 4.2 an activity against Ctenocephalidescanisand Pulex irritansfleas has been demonstrated.

Imidacloprid has a high affinity for the nicotinergic acetylcholine receptors in the post-synaptic region of the central nervous system (CNS) of the flea. The ensuing inhibition of cholinergic transmission in insects results in paralysis and death. Due to the weak nature of the interaction with mammalian nicotinergic receptors and the postulated poor penetration through the blood-brain barrier in mammals, it has virtually no effect on the mammalian CNS. Imidacloprid has minimal pharmacological activity in mammals.


Flumethrinis an ectoparasiticide of the synthetic pyrethroid group. According to current knowledge the synthetic pyrethroids interfere with the sodium channel of nerve cell membranes, resulting in a delay in repolarization of the nerve and finally killing of the parasite. In studies on structure-activity relationship of a number of pyrethroids interference with receptors of a certain chiral conformation was noted thereby causing a selective activity on ectoparasites. No anti-cholinesterase activity was noted with these compounds. Flumethrin is responsible for the product’s acaricidal activity and also prevents production of fertile eggs by its lethal effect on female ticks. In an in-vitrostudy 5 to 10 % of Rhipicephalussanguineus ticks exposed to a sublethal dose of 4 mg flumethrin/L laid eggs which had a modified appearance (shrivelled, dull and dry) indicating a sterilising effect.


In addition to the indications listed under section 4.2 activity against Ixodes hexagonusand the non-European tick species Amblyomma americanum has been demonstrated.

The product provides repellent (anti-feeding) activity against the claimed ticks, thus preventing repelled parasites from taking a blood meal and thereby indirectly aids in the reduction of the risk of Vector-Borne Disease transmission. Indirect protection against the transmission of Cytauxzoon felis(transmitted by Amblyomma americanum ticks) has been shown in one laboratory study in a small number of animals at one month after treatment, thereby reducing the risk of diseases caused by this pathogen under the conditions of this study.


5.2 Pharmacokinetic particulars


Both active ingredients are slowly and continuously released in low concentrations from the polymer matrix system of the collar towards the animal. Both actives are present in the cat’s haircoat in acaricidal/insecticidal concentrations during the entire efficacy period. The active substances spread from the site of direct contact over the entire skin surface. Target animal overdose and serum kinetic studies have established that imidacloprid reached the systemic circulation transiently while flumethrin was mostly not measurable. Oral absorption of both active substances is not relevant for the clinical efficacy.
