Imidacloprid has a low octanol–water partition coefficient (Kow=3.72), which is consistent with it not accumulating in biological tissue or the food chain. The no observable effect level was determined to be 500 ppm (12.5 mg/kg of body weight). Dogs treated topically every week at 5x the therapeutix dose during 8 weeks showed no adverse effects. The liver was the principal target organ, with hypertrophy of hepatocytes and sporadic cell necrosis in high-dose males only. The first involves oxidative cleavage to imidazolidine and 6-chloronicotinic acid, with the imidazolidine moiety excreted via the urine. Crosaz O, Bonati S, Briand A, Chapelle E, Cochet-Faivre N, Ka D, Darmon-Hadjaje C, Varloud M, Guillot J. Parasit Vectors. 1 It is available as a topical formulation and was approved by the Food and Drug Administration as an oral chewable formulation in 2015. Product Use Spot-on insecticide for flea control in dogs and cats. Choosing Treatment for Dogs With Generalised Demodicosis – Isoxazolines or Imidacloprid and Moxidectin? Insects become disoriented at sublethal doses and stop foraging for food. Resistance was conferred by a single-point mutation at Tyrosine151Serine (Y151S) in the alpha subunit of nAChR and a correlation was observed between the frequency of the point mutation and imidacloprid resistance (Liu et al., 2005). Imidacloprid is the most well-known and widely used representative of the neonicotinoid insecticides. Some of the dogs were washed or shampooed after treatment without showing statistical differences in efficacy. Larry P. Sheets, in Hayes' Handbook of Pesticide Toxicology (Third Edition), 2010.

The formulation and dosage schedule are designed to provide a minimum of 4.5 mg/lb (10 mg/kg) imidacloprid and 1.1 mg/lb (2.5 mg/kg) moxidectin based on body weight. Imidacloprid has a high margin of safety due to the high insecticidal specificity and low mammalian toxicity (Nagata et al., 1999). All information is peer reviewed. Due to its high insecticidal potency and relatively low mammalian toxicity, imidacloprid has a very high margin of safety. Researchers measured residue transfer of a commercial spot-on product containing imidacloprid on dogs' fur to people. It is a broad-spectrum neonicotinoid insecticide, with excellent systemic and contact activity that supports its use on many food crops, turf, and ornamentals and for termite and flea control.

Over the same time EPA documented over 4 hundred deaths of domestic animals, mainly dogs and cats treated with flea and tick products. Insecticidal activity and neurotoxic signs in mammals are mediated by actions on nicotinic acetylcholine receptors (nAChR). Acetylcholine (ACh) is an endogenous agonist as well as being an excitatory neurotransmitter of the cholinergic nervous system. Imidacloprid is relatively new compound with many uses. Rabbits were administered imidacloprid by the dermal route for 3 weeks at a dose of 1000 mg/kg for 6 hours a day, 5 days a week. Imidacloprid is a neonicotinoid compound that is used as an insecticide for dermal application on animals, for termite and grub control and as an insecticide for crop protection. In surface runoff collected from potato farms in Prince Edward Island following rainfall events in 2001 and 2002, concentrations ranged from below the detection limit of 0.5 µg/L to 11.9 µg/L (CCME, 2007a). Comparative in vivo adulticidal activity of a topical dinotefuran versus an imidacloprid-based formulation against cat fleas (Ctenocephalides felis) on cats. Another mechanism for resistance is amino acid modification of the target site (nAChRs). Category: Supplements. The dose of imidacloprid is based on the weight of the dog. 2017 Oct 27;8(4):118. doi: 10.3390/insects8040118. This insecticide spray works systemically and moves through the foliage to the roots of treated vegetation so that targeted insects that feed on the plants die. B. tabaci that are imidacloprid susceptible typically do not metabolize 14C-imidacloprid into P450-mediated metabolites (Rauch and Nauen, 2003). Learn how advantus®, an FDA-approved soft chew, uses imidacloprid to start killing fleas within 1 hour. There are two major routes of metabolism in mammals. This study demonstrates that a single treatment with imidacloprid is able to effectively control flea infestations in dogs and cats for at least 28 days and significantly contributes to the improvement or disappearance of clinical signs of FAD. Imidacloprid, better know as Advantage® or K9 Advantix®, is an insecticidal agent for dogs that acts on the central nervous system of insects causing impairment and subsequent death. Clipboard, Search History, and several other advanced features are temporarily unavailable. Compend Contin Educ Vet. Parasit Vectors. Vet Ther. Acute Toxicity and Tolerance of Imidacloprid.

Imidacloprid is generally safe to use on dogs over seven weeks of age and any size. NCI CPTC Antibody Characterization Program. Imidacloprid is not mutagenic or carcinogenic, it is not a primary embryotoxicant, is not teratogenic, and has no effect on reproduction or development. The resistance appears to be associated with monooxygenase-mediated activity, with 5-hydroxy-imidacloprid being the only resultant metabolite after topical application of imidacloprid (Rauch and Nauen, 2003). Stanneck D, Kruedewagen EM, Fourie JJ, Horak IG, Davis W, Krieger KJ. Imidacloprid, also an ingredient in Advantage , is an insecticidal agent that acts on the central nervous system of … Advocate treats … Resistance was conferred by a single-point mutation at Tyrosine151 to Serine (Y151S) in the alpha subunit of nAChR, and a correlation was observed between the frequency of the point mutation and imidacloprid resistance (Liu et al., 2005b). They end up in the house and are difficult to remove. Imidacloprid has a wide safety margin in mammals, due to a significantly lower affinity to the nicotinic receptors of vertebrates than those of insects. DeLorenzo, in Fish Physiology, 2013. 56. The limited data reported on dogs suggest that mild hepatotoxicity might occur with prolonged exposure, but neurologic effects have not been reported at doses up to 2500 ppm.
