Zoetis has launched Stronghold Plus (selamectin/sarolaner), a topical combination of parasiticides that treats ticks, fleas, ear mites, lice and GI nematodes and prevents heartworm disease in cats.

Stronghold Plus contains the same selamectin found in common-or-garden Stronghold, licensed for the treatment of fleas, flea allergic dermatitis, ear mites (Otodectes cynotis), roundworm (Toxocara cati), intestinal hookworms (Ancylostoma tubaeforme), biting lice (Felicola subrostratus), and for the treatment of heartworm disease caused by Dirofilaria immitis. 

To that has been added sarolaner, a new acaricide and insecticide which is also effective for five weeks against Ixodes ricinusIxodes hexagonus, and for four weeks against Dermacentor reticulatus and Rhipicephalus sanguineus.

Clint Lewis, Executive Vice President and President International Operations, said: "The launch of  Stronghold Plus enables Zoetis to offer veterinarians in the European Union a new topical choice that treats the parasites commonly presenting a threat to cats with one convenient monthly dose.

For the first time, we have combined our new, versatile parasiticide sarolaner with the active ingredient in Stronghold, selamectin, resulting in the first approval of sarolaner for use in cats. We see sarolaner as a promising platform for future product lines and lifecycle innovations and are pleased with the positive data that sarolaner and its combination continue to generate in studies.”

Domenico Otranto, Professor of Parasitology at Bari University in Italy, who has reviewed the product data of Stronghold Plus, said: "A number of laboratory and field studies show the efficacy of the single spot-on application of Stronghold Plus for at least one month. Veterinarians in Europe now have a very effective option for the treatment and control of four prominent species of ticks commonly found on cats while maintaining proven efficacy against fleas, GI worms, heartworms, ear mites and lice. Ultimately, pet owners and practitioners have a new tool for improving health and welfare of cats."
