Description

BRAVECTO CHEWABLE 100 MG

Indications

BRAVECTO Chewable 100 mg is an antiparasitic medication indicated for the treatment and prevention of flea infestations and the treatment of tick infestations in dogs. It is effective against various species of fleas and ticks, including Ixodes ricinus (castor bean tick), Rhipicephalus sanguineus (brown dog tick), and Dermacentor variabilis (American dog tick). This product is suitable for dogs weighing between 4.4 to 9.8 kg (9.8 to 22 lbs) and is typically administered every 12 weeks for optimal efficacy.

Mechanism of Action

BRAVECTO contains the active ingredient fluralaner, which is a member of the isoxazoline class of compounds. Fluralaner works by inhibiting the function of the gamma-aminobutyric acid (GABA) and glutamate-gated chloride channels in the nervous system of parasites. This inhibition leads to hyperexcitation of the nervous system, resulting in paralysis and death of the fleas and ticks. The rapid onset of action allows for quick relief from infestations, with fluralaner remaining effective for up to 12 weeks after administration.

Pharmacological Properties

Fluralaner is well-absorbed following oral administration, with peak plasma concentrations typically occurring within a few hours. The drug has a high bioavailability and is distributed widely throughout the body, including the skin and adipose tissue, where it exerts its antiparasitic effects. The elimination half-life of fluralaner is approximately 12 days, allowing for sustained efficacy against fleas and ticks. The drug is primarily metabolized by the liver and excreted via feces and urine.

Contraindications

BRAVECTO should not be administered to dogs that are hypersensitive to fluralaner or any of the excipients in the formulation. It is also contraindicated in dogs less than 6 months of age or those weighing less than 4.4 kg (9.8 lbs). Additionally, BRAVECTO should not be used in breeding, pregnant, or lactating dogs unless specifically directed by a veterinarian.

Side Effects

BRAVECTO is generally well-tolerated in dogs; however, some side effects may occur. Commonly reported side effects include vomiting, diarrhea, decreased appetite, lethargy, and increased thirst. In rare cases, more severe reactions such as seizures or allergic reactions may occur. If any adverse effects are observed, it is essential to consult a veterinarian promptly for further evaluation and management.

Dosage and Administration

The recommended dosage of BRAVECTO Chewable 100 mg is based on the weight of the dog. It should be administered as a single chewable tablet every 12 weeks. It is important to ensure that the dog consumes the entire tablet to achieve the desired therapeutic effect. The chewable formulation is palatable, making it easy for dogs to ingest. For dogs weighing between 4.4 kg and 9.8 kg, the 100 mg tablet is appropriate. For dogs outside this weight range, other formulations of BRAVECTO are available to ensure proper dosing.

Interactions

Currently, there are no known significant drug interactions with fluralaner. However, it is advisable to inform the veterinarian of any other medications, supplements, or treatments the dog may be receiving. Caution is recommended when using BRAVECTO in conjunction with other products that may affect the central nervous system, as the combined effects may lead to increased risk of adverse reactions.

Precautions

Before administering BRAVECTO, it is crucial to conduct a thorough health assessment of the dog. Dogs with a history of seizures or neurological disorders should be monitored closely when receiving this medication. Additionally, while BRAVECTO is safe for most dogs, it is always best practice to consult with a veterinarian prior to starting any new medication, especially in dogs with pre-existing health conditions or those that are on concurrent medications. Regular veterinary check-ups are recommended to ensure the ongoing health and well-being of the pet.

Clinical Studies

Clinical studies have demonstrated the efficacy and safety of BRAVECTO in the treatment of flea and tick infestations in dogs. In one study, BRAVECTO showed a 100% efficacy rate against fleas within 12 hours of administration and maintained over 95% efficacy against fleas for 12 weeks. Another study highlighted the rapid action of BRAVECTO against various tick species, with significant reductions in tick counts observed within 24 hours. These studies support the use of BRAVECTO as an effective and convenient option for flea and tick control in dogs.

Conclusion

BRAVECTO Chewable 100 mg is a highly effective and convenient treatment for flea and tick infestations in dogs. Its long-lasting effects, ease of administration, and rapid onset of action make it a preferred choice among pet owners and veterinarians. However, as with any medication, responsible use is essential to ensure the safety and health of the pet. Regular veterinary consultations and adherence to the recommended dosage and administration guidelines will help maximize the benefits of BRAVECTO while minimizing the risk of adverse effects.
