Patent number: 8901154Abstract: A topical insecticide preparation is provided which can be safe to use and avoids many common deleterious side effects of conventional topical insecticides. The topical insecticide contains a combination of a first pyrethroid insecticide effective for killing fleas, a second pyrethroid insecticide effective for killing ticks, and an insect growth regulator (IGR). The topical insecticide preparation can be packaged together or packaged so that the first and second pyrethroid insecticides are stored separately prior to administration of the insecticide preparation to the animal. The combination of the first and second pyrethroid insecticides with an insect growth regulator results in an insecticide preparation formulated to have enhanced insecticidal activity against fleas and ticks compared to the effectiveness of the first and second insecticides used alone.Type: GrantFiled: January 31, 2011Date of Patent: December 2, 2014Assignee: Ceva Animal Health LLCInventors: Ian Cottrell, Albert Ahn, Linda Dorneval

Patent number: 7855231Abstract: A topical insecticide is provided which can be safe to use and avoids many common deleterious side effects of conventional topical insecticides. The insecticide contains an insecticide and an insect growth regulator effective for killing fleas, flea larvae and flea eggs. The insecticide is formulated by dissolving an insecticidal (tetrahydro-3-furanyl) methylamine derivative and an insect growth regulator (IGR) in a solvent containing N-octyl pyrrolidone and/or N-methyl pyrrolidone to increase the solvency of the IGR component, thereby providing an insecticide having high insecticidal activity.Type: GrantFiled: April 27, 2007Date of Patent: December 21, 2010Assignee: Summit VetPharm, LLCInventors: Ian W. Cottrell, Albert Ahn, Linda Dorneval
