4. CLINICAL PARTICULARS

4.1 Target species

Cat.

4.2 Indications for use, specifying the target species

The treatment and prevention of flea and tick infestations in cats. The
product controls infestations with Felicola subrostratus biting lice on
cats.

4.3 Contra-indications

Do not use on kittens less than 8 weeks old and/or weighing less than 1 kg.
Do not use on animals that are unwell, are undergoing treatment for, or are
recovering from illness.
Do not use in rabbits, as adverse drug reactions and even death could
occur.

Do not use in animals with known hypersensitivity to the active substance or
to any of the other ingredients.

4.4 Special warnings for each target species

When treating infestations of lice, all in-contact cats should be treated with
an appropriate product at the same time.

For optimum control of flea problems in a multi-pet household, all dogs and
cats in the household should be treated with a suitable insecticide.

There may be an attachment of single ticks. For this reason transmission of

infectious diseases cannot be completely excluded if conditions are
unfavourable.
Fleas from pets often infest the animal’s basket, bedding and regular resting
areas such as carpets and soft furnishings which should be treated, in case
of massive infestation and at the beginning of the control measures, with a
suitable insecticide and vacuumed regularly.

FRONTLINE Spot On Cat prevents re-infestation with all stages of
Rhipicephalus spp. Dermacentor spp. and Ixodes spp. ticks for up to one
month, depending on the level of environmental challenge.

No data on the effect of bathing/shampooing on the efficacy of the product
in cats are available. However, based on information available for dogs
shampooed from 2 days after application of the product, it is not
recommended to bath animals within 2 days after application of the product.

4.5 Special precautions for use

(i) Special precautions for use in animals

For external use only.

Animals should be weighed accurately prior to treatment.
It is important to make sure that the product is applied to an area where the
animal cannot lick it off and to make sure that animals do not lick each other
following treatment.
Avoid contact with the animal’s eyes.
Do not overdose.

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

Keep stored pipettes in the original packaging until ready to use. In order to
prevent children from getting access to used pipettes, dispose of used
pipettes immediately

This product can cause mucous membrane and eye irritation. Therefore,
contact of the product with mouth and eyes should be avoided.

People with a known hypersensitivity to insecticides or alcohol should avoid
contact with the product.

Avoid contents coming into contact with the fingers. If this occurs, wash
hands with soap and water.

After accidental ocular exposure the eye should be rinsed carefully with
plain water.

Wash hands after use.

Do not smoke, drink or eat during application.

Treated animals should not be handled until the application site is dry, and
children should not be allowed to play with treated animals until the
application site is dry. It is therefore recommended that animals are not
treated during the day, but should be treated during the early evening, and
that recently treated animals should not be allowed to sleep with owners,
especially children.

(iii) Other precautions
The alcohol carrier may have adverse effects on painted, varnished or other
household surfaces or furnishings.

4.6 Adverse reactions (frequency and seriousness)

If licking occurs, a brief period of excessive salivation/drooling may be
observed due mainly to the nature of the solvents in the product.

Among the extremely rare suspected adverse reactions, short-lived skin
reactions at the application site (scaling, local hair loss, itchiness,
reddening) and general itchiness or hair loss have been reported after use.
Exceptionally, excessive drooling, reversible nervous signs including
hyperaesthesia (increased sensitivity to light and sound or overexcited or
unusual behavior), depression, or vomiting have been observed after use.

The frequency of adverse reactions is defined using the following
convention:
– very common (more than 1 in 10 animals displaying adverse reaction(s)
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

Laboratory studies using fipronil have not shown any evidence of toxicity to
the embryo or developmental abnormalities in the young.
The safety of the product was demonstrated in breeding, pregnant and
lactating queens treated with multiple consecutive doses with up to 3 times
the maximum recommended dose.
The product can be used during pregnancy and lactation.

4.8 Interaction with other medicinal products and other forms of

interaction

None known.

4.9 Amounts to be administered and administration route

Route of administration: By topical application to the skin.
Dosage: 1 pipette of 0.5 ml per cat (approximately 7.5 15 mg/kg)
Method of Administration: Hold upright. Tap the narrow part of the pipette to
ensure the contents are within the main body of the pipette. Break back the
snap-off top from the spot-on pipette along the scored line.

Part the coat between the shoulder blades until the skin is visible. Place the
tip of the pipette against the skin and squeeze gently to empty its contents
directly onto the skin, preferably at two spots, one at the base of the skull
and a second 2-3cms further back.

Care should be taken to avoid excessive wetting of the hair with the product
since this will cause a sticky appearance of hairs at the treatment spot.
However, should this occur, it will disappear within 24 hours post
application.

In the absence of safety studies, the minimum treatment interval is 4 weeks.

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

No undesirable effects were observed in target animal safety studies in cats
and kittens aged 8 weeks and older and weighing about 1 kg treated once a
month at five times the recommended dose for six consecutive months. The
risk of experiencing adverse effects may however increase with overdosing
(see section 4.6.). Itching may occur following treatment.

Overdose application of the product will cause a sticky appearance of hairs
at the treatment spot. However, should this occur, it will disappear within 24
hours post application.

4.1 Withdrawal periods

Not applicable.

5. PHARMACOLOGICAL PROPERTIES

Pharmacotherapeutic group: Other ectoparasiticides for topical use.

ATC Vet Code: QP53AX15

5.1 Pharmacodynamic properties

Fipronil is an insecticide/acaricide in the phenylpyrazole family. It acts by
inhibiting the GABA complex, binding to the chloride channel and thereby
blocking pre- and post-synaptic transfer of chloride ions across the
membrane. This results in uncontrolled activity of the central nervous
system and death in insects and acarids.

Fipronil exhibits an insecticidal and acaricidal activity against fleas
(Ctenocephalides spp), ticks (Rhipicephalus spp. Dermacentor spp. and
Ixodes spp.) and lice (Felicola subrostratus) in the cat.

The product is effective against fleas for up to 5 weeks in cats, depending
on the level of environmental challenge. Newly arriving fleas are killed
within 24 hours of landing on the animal.

5.2 Pharmacokinetic properties

*Absorption

After local application of the product in the cat, absorption of fipronil through
the skin is negligible.

*Distribution

After application, a concentration gradient of fipronil is set up on the fur of
the animal extending from the point of application to the peripheral areas
(lumbar zones, flanks,…).

*Biotransformation

In in vitro' studies with subcellular liver fractions, the principal metabolite is the sulfone derivative of fipronil. However, this may be of limited relevancein vivo’ as fipronil is poorly absorbed in the cat.

*Elimination

The concentrations of fipronil on the hair decrease with time to attain a level
of approximately 1 g.g 1 two months after treatment.
