Ceva Animal Health has launched Duoflect, a new spot on for the treatment and prevention of flea and tick infestations in cats and dogs and their environment.

Duoflect contains a new formulation of fipronil and (s)-methoprene which, according to the company, offers a 100% longer duration of action against fleas in cats (eight weeks), and a 13% longer duration in dogs (nine weeks) than the market-leading fipronil combination.

Ceva says the Duoflect's duration of action against ticks is 150% longer in cats (5 weeks) and 50% longer it cats (six weeks) than the market-leading competitor. 

Duoflect acts against both adult fleas on the animal and immature flea stages in the environment and it can also be used as part of a treatment strategy for the control of flea allergy dermatitis (FAD).

Duoflect is available in free-standing pipettes for easier administration and handling of the pet. The pipettes are packed in child-resistant aluminium blisters to reduce the risk of accidents at home.

Nicki Glen, marketing project manager for Duoflect at Ceva Animal Health said: "Recent research1 has revealed that two main factors in prescribing parasitic control products are the length of action and the increased efficacy against fleas.

"Duoflect's new strength formulation provides a longer duration of action than the market-leading fipronil combination, while its efficacy is proven through 13 recent laboratory and field trials1."

Duoflect is competitively priced and is available in boxes of three or six pipettes and in five presentations: small cats (1-5kg), large cats (>5kg) and small dogs (2-10kg) and medium dogs (10-20kg), large dogs (20-40kg) and extra large dogs (40-60kg).  It is suitable for cats and dogs from eight weeks of age.

Ceva Animal Health has produced a range of supporting marketing materials including client leaflets.
