Zoetis launches Simparica, a new chewable monthly flea and tick preventative (March 2016)
Simparica (sarolaner) Chewables received European Commission endorsement in November as an approved killer of four common European ticks and two types of fleas. The . formulation is indicated for use against adult fleas, flea infestations and the Lone Star, Gulf Coast, American and brown dog ticks. Sarolaner, the active ingredient in Simparica, is in the same isoxazoline class as Bravecto and NexGard (see below). The company claims that its product kills fleas faster than NexGard, preventing them from reproducing. Each tablet is effective for one month. They are approved for dogs at least six months in age.
Update: A new study shows that Simparica at the usual flea-preventive dose is effective against demodectic mange (demodex), as well as otodectic mange. See Demodex below for more information.
