Fluralaner is a potent, broad-spectrum ectoparasiticide used primarily in veterinary medicine to control fleas and ticks in dogs and cats. Known commercially as Bravecto, fluralaner has revolutionized the way veterinarians manage these common and often troublesome parasites. Its efficacy, safety profile, and long-lasting action have made it a preferred choice among pet owners and veterinary professionals alike. This comprehensive guide explores the various applications of fluralaner, its mechanisms, administration protocols, safety considerations, and its impact on animal health and welfare.

Understanding Fluralaner

1. Chemical and Pharmacological Profile

Fluralaner belongs to the isoxazoline class of compounds, which are known for their potent insecticidal and acaricidal properties. It acts on the nervous system of arthropods, leading to their paralysis and death. Unlike some other ectoparasiticides, fluralaner has a long-lasting effect, providing extended protection with a single dose.

2. Mechanism of Action

Fluralaner targets the gamma-aminobutyric acid (GABA) and glutamate-gated chloride channels in the nervous system of fleas and ticks. By inhibiting these channels, fluralaner disrupts the transmission of nerve signals, causing hyperexcitation, paralysis, and eventual death of the parasites. This mechanism is highly specific to arthropods, making fluralaner safe for mammals when used as directed.

Applications in Veterinary Medicine

1. Flea Control in Dogs and Cats

Fleas are a common nuisance for pets and their owners, causing itching, allergic reactions, and potentially transmitting diseases. Fluralaner provides effective and long-lasting control of flea infestations in both dogs and cats.

• Prophylactic Use: Administering fluralaner as a preventive measure ensures that pets remain free from fleas for up to 12 weeks. This extended duration is particularly beneficial in reducing the need for frequent treatments and minimizing the chances of re-infestation.
• Therapeutic Use: In cases of existing flea infestations, fluralaner quickly eliminates adult fleas and prevents the development of new ones. Its rapid onset of action alleviates the discomfort caused by flea bites and improves the overall health of the pet.

2. Tick Control in Dogs and Cats

Ticks are vectors for several serious diseases, including Lyme disease, ehrlichiosis, and anaplasmosis. Controlling ticks is crucial for protecting the health of pets and preventing the transmission of these diseases.

• Prophylactic Use: A single dose of fluralaner provides protection against various tick species for up to 12 weeks in dogs and 8-12 weeks in cats. This long-lasting effect significantly reduces the risk of tick-borne diseases.
• Therapeutic Use: Fluralaner is effective in eliminating ticks that are already attached to the pet, reducing the risk of disease transmission. Its acaricidal properties ensure that ticks are killed before they can cause significant harm.

3. Treatment of Mite Infestations

Mites can cause severe skin conditions in pets, including mange and otitis externa. Fluralaner has shown efficacy against certain mite species, providing relief from these parasitic infestations.

• Demodicosis (Demodectic Mange): Caused by Demodex mites, this condition can lead to severe skin inflammation and secondary infections. Fluralaner helps in reducing the mite population and improving the skin condition of affected pets.
• Otodectic Mange (Ear Mites): Fluralaner is also effective against ear mites, providing relief from itching and irritation. Its systemic action ensures that mites are eradicated not only in the ears but also in other parts of the body.

Administration and Dosage

1. Routes of Administration

Fluralaner is available in several formulations, including oral chewable tablets for dogs and topical solutions for both dogs and cats. The choice of formulation depends on the pet's preferences, ease of administration, and specific needs.

• Oral Chewable Tablets: These are flavored and palatable, making them easy to administer to dogs. The oral route ensures systemic distribution and prolonged efficacy.
• Topical Solutions: These are applied directly to the skin, providing a convenient option for cats and dogs that may be difficult to medicate orally. The topical route ensures that the medication is absorbed through the skin and distributed throughout the body.

2. Dosage Guidelines

The dosage of fluralaner varies based on the species, weight, and formulation. For dogs, the recommended dose is 25-56 mg/kg body weight, administered as a single oral chewable tablet every 12 weeks. For cats, the recommended dose is 40-94 mg/kg body weight, administered as a single topical application every 12 weeks.

Safety and Efficacy

1. Safety Profile

Fluralaner has undergone extensive safety testing and has been found to be well-tolerated in both dogs and cats. Adverse effects are rare and generally mild, including transient gastrointestinal disturbances and mild skin reactions at the application site. Its selective action on arthropod-specific channels contributes to its safety in mammals.

2. Efficacy Studies

Numerous clinical studies have demonstrated the high efficacy of fluralaner in controlling fleas and ticks. These studies have shown that fluralaner provides near-complete protection against flea infestations and significantly reduces tick burdens. Its long-lasting action makes it a preferred choice for continuous parasite control.

Benefits of Using Fluralaner

1. Extended Protection

One of the most significant advantages of fluralaner is its prolonged duration of action. A single dose provides up to 12 weeks of protection against fleas and ticks, reducing the frequency of treatments and ensuring continuous protection.
