1. "Fluralaner - Bravecto
Fluralaner is a representative of the isoxazolines, a new class of insecticides discovered in the 200s. Fluralaner under the trade name BRAVECTO (MSD ANIMAL HEALTH) has been recently approved in the EU for use on dogs.
There is so far little information available on this active ingredient. It is similar to
afoxolaner, another active ingredient introduced by MERIAL (NEXGARD) recently approved in the US and the EU.
Fluralaner is available for oral administration to dogs, i.e. it has a systemic mode of action. Ingested fluralaner is rapidly absorbed into blood and distributed throughout the whole body of the treated dog. Blood-sucking parasites (mainly fleas and ticks) are killed during their blood meal.
But the systemic mode of action means also that for fleas and/or ticks to be killed, they have to bite the dog first and suck enough blood before the ingested active ingredient kills them.
Whether killing is fast enough to prevent disease transmission is not yet known"

Parasites need to start feeding on the host to become exposed to fluralaner; therefore the risk of the transmission of parasite borne diseases cannot be excluded..."
