Definitions
- the present invention relates to a topical veterinary pharmaceutical composition combining N-phenylpyrazole, preferably fipronil, and an ectoparasiticidal agent, especially permethrin, for the treatment of infestations by external parasites (flea, tick, mosquito, sandfly, sarcopter). .
- Pets are often infested with one or more parasites feeding on blood such as dog fleas, cat fleas, ticks, or sarcoptes (responsible for scabies).
- Fleas are wingless insects, with laterally compressed bodies and highly developed legs, suitable for jumping. They are ectoparasites, sucking blood from mammals or birds. The 2000 listed species belong to the order of siphonaptera. Two species of fleas are commonly found in Europe; it is the cat's flea (Ctenocephalides felis) and the flea (Ctenocephalides canis) that live in the fur of animals.
- Flea bites cause itching in both animals and humans.
- the saliva of the flea secreted with each bite) can also, according to individuals, cause allergic reactions, immediate or delayed. These reactions result in various skin and itchy lesions.
- Flea Allergy Dermatitis (DAPP) is the most common cause of pruritus in dogs. In France, in adult dogs, it accounts for almost half of the pruriginous dermatoses.
- the carnivore becomes infested by swallowing parasitic fleas. This infestation can cause anal pruritus, engorgement of anal sacs, and perineal dermatitis. Therefore, it is sometimes advisable to worm regularly the animals in addition to the fight against fleas.
- ticks (Rhipicephalus sp., Ixodes sp., Dermacentor sp., Amblyomma sp., ...) can also cause stress to the animal and harm its health. They can also harm the man. But the most serious problem of ticks is that they are a vector of pathogens that can affect the animal as much as the man. Major diseases to be avoided include Borellioses (Lyme disease Borellia burgdorferi), Babesioses (Babesia sp. Piroplasmosis), and Rickettsioses. Ticks can also release toxins with crippling, inflammatory, and sometimes life-threatening properties.
- the gall (Demodex sp., Sarcoptes sp., Otodectes sp., ...) is particularly difficult to fight because there are very few effective active ingredients; it requires frequent treatments.
- Mosquitoes (Culex sp., Aedes sp., Anopheles sp., ...) play an extremely important role in human or animal health because they concentrate, beyond their role of nuisance by the bites they inflict, the the most important group of vectors of pathogens transmissible to humans, including many zoonoses. They are vectors of three groups of pathogens for humans: Plasmodium, filarial as well as many arboviruses. They are present on all the Earth's land surface (except Antarctica), both in forest, savannah and urban environments, as soon as a surface of fresh or brackish water, even if reduced or temporary, is available. Sixty-five species are referenced in metropolitan France.
- Phlebotomine (Phlebotomus sp., ...) are blood-sucking insects.
- the sandfly is an insect vector. If infected, its sting transmits leishmaniasis.
- N-phenylpyrazole and permethrin derivatives have been known for a long time because the overlap and the complementarity of the action spectra of the active ingredients make them particularly interesting in the fight against pests in agriculture and in the veterinary field where each of the active ingredients is commonly used.
- the Applicant has found that permethrin changes phase at low temperature, that is to say crystallizes when it is formulated in high concentration with another active ingredient in an excipient or a mixture of excipients according to the invention.
- Prior art preservation tests at 8 ° C carried out on formulations combining between 51 and 75% w / v of permethrin and between 0 and 10% w / v of fipronil in the diethylene glycol monoethyl ether show a systematic phase change of the formulation (appearance of crystals at the latest after 5 days of storage) as long as the permethrin content exceeds 65% by weight / volume; the increase in the fipronil content in the formulation lowers this permethrin concentration threshold from which it changes phase.
- the aim of the Applicant is to provide a product for the prevention and treatment of flea infestations in domestic animals which has a broad spectrum of action, which is easy to administer, while having a rapid action and persistent.
- Another objective of the invention is the development of stable compositions whose storage does not require any particular precaution (such as, for example, the maintenance of the product at a temperature above 20 ° C.).
- N-phenylpyrazoles are a large family of compounds with a very wide spectrum of activity, including antiparasitic activities; they are described in patent applications EP 0 295 117 and EP 0 352 944.

- the formulation developed within the scope of this invention comprises, in addition to the active ones, an aliphatic cyclic carbonate (ethylene or propylene carbonate) and an aliphatic, cyclic or acyclic polyether (in particular, diethylene glycol monoethyl ether); it is preferably topical for spot-on administration.
- This application makes no mention of the problem of crystallization of the active ingredients, it should however be noted that no example of composition comprises a permethrin content greater than 45 g / 100 ml.
- N-phenylpyrazole especially, fipronil
- an inhibitor of the crystallization of the product when it is applied to the hair of the animal is preferably a combination of a surfactant (Polysorbate 80) and a film-forming agent (PVP, polyvinyl alcohol and copolymers of vinyl acetate and vinylpyrrolidone);
