Fluralaner, (INN) [12] sold under the brand name Bravecto among others, is a systemic insecticide and acaricide that is administered orally [13] or topically. [14]

Contents

Mode of action

Fluralaner inhibits γ-aminobutyric acid (GABA)-gated chloride channels (GABAA receptors) and L-glutamate-gated chloride channels (GluCls). [15] Potency of fluralaner is comparable to fipronil (a related GABA-antagonist insecticide and acaricide). [16]

Society and culture

The US Food and Drug Administration (FDA) approved it for flea treatment in dogs in May 2014, [17] and approved the combination fluralaner/moxidectin (Bravecto Plus) as a topical treatment for cats in November 2019. [18] [19] [20] [21] The EU approved fluralaner in March 2014. [5] [6] [22] Australia approved it for the treatment and prevention of ticks and fleas on dogs in January 2015. [23] For treating mites in chickens, a solution for use in drinking water is available under the brand name Exzolt [24] and was approved for use in the EU in 2017. [25]

Bravecto 1-Month was approved by the FDA in November 2024 for the addition of the indication for the treatment and control of Haemaphysalis longicornis (Asian longhorned tick) infestations for one month in dogs and puppies eigjht weeks of age and older, and weighing 4.4 pounds (2.0 kg) or greater. [26] [27]

Research

Fluralaner is being investigated to determine its ability to reduce the incidence of mosquito-borne diseases, [28] as well as bed bugs. [29] [30]

<span class="mw-page-title-main">Scabies</span> Human disease

Scabies is a contagious human skin infestation by the tiny (0.2–0.45 mm) mite Sarcoptes scabiei, variety hominis. The word is from Latin: scabere, lit. 'to scratch'. The most common symptoms are severe itchiness and a pimple-like rash. Occasionally, tiny burrows may appear on the skin. In a first-ever infection, the infected person usually develops symptoms within two to six weeks. During a second infection, symptoms may begin within 24 hours. These symptoms can be present across most of the body or just in certain areas such as the wrists, between fingers, or along the waistline. The head may be affected, but this is typically only in young children. The itch is often worse at night. Scratching may cause skin breakdown and an additional bacterial infection in the skin.

<span class="mw-page-title-main">Tacrolimus</span> Immunosuppressive drug

Tacrolimus, sold under the brand name Prograf among others, is an immunosuppressive drug. After allogenic organ transplant, the risk of organ rejection is moderate. To lower the risk of organ rejection, tacrolimus is given. The drug can also be sold as a topical medication in the treatment of T cell-mediated diseases such as eczema and psoriasis. For example, it is prescribed for severe refractory uveitis after a bone marrow transplant, exacerbations of minimal change disease, Kimura's disease, and vitiligo. It can be used to treat dry eye syndrome in cats and dogs.

<span class="mw-page-title-main">Mange</span> Type of skin disease caused by parasitic mites

Mange is a type of skin disease caused by parasitic mites. Because various species of mites also infect plants, birds and reptiles, the term "mange", or colloquially "the mange", suggesting poor condition of the skin and fur due to the infection, is sometimes reserved for pathological mite-infestation of nonhuman mammals. Thus, mange includes mite-associated skin disease in domestic mammals, in livestock, and in wild mammals. Severe mange caused by mites has been observed in wild bears. Since mites belong to the arachnid subclass Acari, another term for mite infestation is acariasis.

<span class="mw-page-title-main">Demodicosis</span> Animal disease caused by hosting of mites (genus Demodex)

Demodicosis, also called Demodex folliculitis in humans and demodectic mange or red mange in animals, is caused by a sensitivity to and overpopulation of Demodexspp. as the host's immune system is unable to keep the mites under control.

<span class="mw-page-title-main">Ivermectin</span> Medication for parasite infestations

Ivermectin is an antiparasitic drug. After its discovery in 1975, its first uses were in veterinary medicine to prevent and treat heartworm and acariasis. Approved for human use in 1987, it is used to treat infestations including head lice, scabies, river blindness (onchocerciasis), strongyloidiasis, trichuriasis, ascariasis and lymphatic filariasis. It works through many mechanisms to kill the targeted parasites, and can be taken by mouth, or applied to the skin for external infestations. It belongs to the avermectin family of medications.

<i>Dirofilaria immitis</i> Species of worm that causes parasitic disease in animals

Dirofilaria immitis, also known as heartworm or dog heartworm, is a parasitic roundworm that is a type of filarial worm, a small thread-like worm, and which causes dirofilariasis. It is spread from host to host through the bites of mosquitoes. Four genera of mosquitoes transmit dirofilariasis, Aedes, Culex, Anopheles, and Mansonia. The definitive host is the dog, but it can also infect cats, wolves, coyotes, jackals, foxes, ferrets, bears, seals, sea lions and, under rare circumstances, humans.

<span class="mw-page-title-main">Doramectin</span> Chemical compound

Doramectin, sold under the brand name Dectomax among others, is a veterinary medication approved by the US Food and Drug Administration (FDA) for the treatment of parasites such as gastrointestinal roundworms, lungworms, eyeworms, grubs, sucking lice, and mange mites in cattle. It is available as a generic medication. It is available as a combination with levamisole under the brand name Valcor.

<span class="mw-page-title-main">Selamectin</span> Topical parasiticide for dogs and cats

Selamectin, sold under the brand name Revolution, among others, is a topical parasiticide and anthelminthic used on dogs and cats. It treats and prevents infections of heartworms, fleas, ear mites, sarcoptic mange (scabies), and certain types of ticks in dogs, and prevents heartworms, fleas, ear mites, hookworms, and roundworms in cats. It is structurally related to ivermectin and milbemycin. Selamectin is not approved for human use.

<span class="mw-page-title-main">Moxidectin</span> Chemical compound

Moxidectin is an anthelmintic drug used in animals to prevent or control parasitic worms (helminths), such as heartworm and intestinal worms, in dogs, cats, horses, cattle, sheep and wombats. Moxidectin kills some of the most common internal and external parasites by selectively binding to a parasite's glutamate-gated chloride ion channels. These channels are vital to the function of invertebrate nerve and muscle cells; when moxidectin binds to the channels, it disrupts neurotransmission, resulting in paralysis and death of the parasite.

The health of dogs is a well studied area in veterinary medicine.

A canine vector-borne disease (CVBD) is one of "a group of globally distributed and rapidly spreading illnesses that are caused by a range of pathogens transmitted by arthropods including ticks, fleas, mosquitoes and phlebotomine sandflies." CVBDs are important in the fields of veterinary medicine, animal welfare, and public health. Some CVBDs are of zoonotic concern.

<i>Dermanyssus gallinae</i> Species of mite

Dermanyssus gallinae is a haematophagous ectoparasite of poultry. It has been implicated as a vector of several major pathogenic diseases. Despite its common names, it has a wide range of hosts including several species of wild birds and mammals, including humans, where the condition it causes is called gamasoidosis. In both size and appearance, it resembles the northern fowl mite, Ornithonyssus sylviarum.
