Selamectin is a GABAA receptor agonist
Selamectin is a commercially available insecticide that is highly effective against fleas, ear mites, and biting lice. It has the potential to control a wide range of parasites, including the dangerous rat flea Otodectes cynotus. It is also available in topical forms for application on animals.
Selamectin is a relatively safe medication for dogs, but some breeds are sensitive to it. These dogs typically have a gene known as MDR1 that makes them less tolerant of high doses of drugs. If your dog has this mutation, it is important to consult your veterinarian. Another side effect of selamectin is that it may interact with other medications. Selamectin is also flammable, so keep it away from extreme heat or open flames.
Another insecticide that is effective against fleas is isoxazolines. These are relatively new chemical products and were first introduced to the market in 2013. They have a broad range of insecticidal activity. Isoxazolines bind to chloride channels in nerve and muscle cells. This leads to hyperexcitation of the target cell and kills it.
It has a terminal half-life of 11 days
Selamectin is rapidly absorbed from the skin and reaches peak plasma concentrations one to three days after oral administration. Its systemic distribution and slow elimination from the plasma results in long-lasting, detectable serum concentrations in dogs. Selamectin’s terminal elimination half-life is eight to eleven days in dogs.
Selamectin binds to chloride channels in the nervous system, blocking neurotransmission. This prevents the transmission of stimuli from nerve to muscle. Moreover, the binding is permanent and results in prolonged hyperpolarization of the cell membrane. Despite the long-lasting effects of selamectin on the human nervous system, the drug has a terminal half-life of eleven days, which makes it an effective insecticide. However, selamectin is not without risk: it can cause hair loss at the site of application.
It is well tolerated
Selamectin flea treatment has been well tolerated by most animals and is a safe and effective treatment for fleas. Selamectin is a broad-spectrum chemical that is well tolerated by dogs and cats and has an excellent safety record. It kills fleas on both the external and internal levels. However, it is important to note that selamectin is slightly slower to kill fleas than other fleaicides.
Selamectin is a macrocyclic lactone compound. Because it is absorbed from the blood of the flea, it is not poisonous to the animal. Moreover, Selamectin also kills other arthropod parasites, including ticks, lice, and mites. This chemical also renders flea eggs infertile, which is important for the prevention of flea infestations.
It prevents heartworms in dogs and cats
In a clinical trial, selamectin flea treatment was shown to effectively prevent heartworms in dogs and cats. The study was conducted in dogs and cats from six weeks to 19 years old. Its effectiveness was verified by the absence of adult heartworm antigen or microfilariae on day 180 after treatment. In addition, selamectin was not associated with severe side effects. The study’s authors concluded that selamectin is safe to use in dogs and cats.
Selamectin is a topical antiparasitic drug that kills fleas and their eggs and prevents their reproduction. This medication is effective against adult fleas and eggs for up to 30 days and prevents heartworms in dogs and cats when applied monthly. It also kills ear mites, sarcoptic mange, roundworm, and hookworm infections in dogs.
It is effective against fleas
The efficacy of imidacloprid, selamectin, and fipronil against fleas is relatively high, especially at 24 hours post-treatment. However, their efficacy decreases with time, and they lose effectiveness by 28 days. In addition, the ectoparasiticide metaflumizone, which is a semicarbazone insecticide, showed only moderate efficacy at 28 days. However, metaflumizone did outperform imidacloprid and selamectin in killing fleas in as little as four weeks.
The effectiveness of selamectin against fleas has been studied in various clinical studies. In one such study, selamectin had a residual kill rate similar to spinosad/milbemycin oxime formulations and achieved 90% efficacy on the KS1 flea strain. These efficacy levels are comparable to other studies that show that selamectin is effective against fleas.
