Selamectin, sold under the brand name Revolution, among others, is a topical parasiticide and anthelminthic used on dogs and cats. [2] It treats and prevents infections of heartworms, fleas, ear mites, sarcoptic mange (scabies), and certain types of ticks in dogs, and prevents heartworms, fleas, ear mites, hookworms, and roundworms in cats.[ citation needed ] It is structurally related to ivermectin and milbemycin.[ citation needed ] Selamectin is not approved for human use.[ citation needed ]
Selamectin is applied topically. [2] It is not miscible in water. [2]
Selamectin disables parasites by activating glutamate-gated chloride channels at muscle synapses. Selamectin activates the chloride channel without desensitization, allowing chloride ions to enter the nerve cells and causing neuromuscular paralysis, impaired muscular contraction, and eventual death.[ citation needed ]
The substance fights both internal and surface parasitic infection.[ citation needed ] Absorbed into the body through the skin and hair follicles, it travels through the bloodstream, intestines, and sebaceous glands;[ citation needed ] parasites ingest the drug when they feed on the animal's blood or secretions.[ citation needed ]
Selamectin has been found to be safe and effective in a 2003 review. [5]
Selamectin has high safety ratings, with less than 1% of pets displaying side effects [ citation needed ]. In cases where side-effects do occur, they most often include passing irritation or hair loss at the application site. Symptoms beyond these (such as drooling, rapid breathing, lack of coordination, vomiting, or diarrhea) could be due to shock as a result of selamectin killing heartworms or other vulnerable parasites present at high levels in the bloodstreams of dogs.[ citation needed ] This would be a reaction due to undetected or underestimated infections prior to using the medication, rather than an actual allergic reaction to the drug itself.[ citation needed ]
Selamectin is sold under various brand names including Selehold, manufactured by KRKA, Selarid manufactured by Norbrook Laboratories Limited, Revolution and Stronghold manufactured by Zoetis, Revolt manufactured by Aurora Pharmaceuticals, and Senergy manufactured by Virbac.
Main rival products for dogs include ivermectin (trade names Stromectol, Ivermec and others) or milbemycin oxime (Interceptor) for heartworms, imidacloprid and moxidectin (Advocate), fipronil (Frontline) or lufenuron (Program) for fleas, or the combination milbemycin oxime/lufenuron (Sentinel) for both.[ citation needed ]
Mange is a type of skin disease caused by parasitic mites. Because various species of mites also infect plants, birds and reptiles, the term "mange", or colloquially "the mange", suggesting poor condition of the skin and fur due to the infection, is sometimes reserved for pathological mite-infestation of nonhuman mammals. Thus, mange includes mite-associated skin disease in domestic mammals, in livestock, and in wild mammals. Severe mange caused by mites has been observed in wild bears. Since mites belong to the arachnid subclass Acari, another term for mite infestation is acariasis.
Demodicosis, also called Demodex folliculitis in humans and demodectic mange or red mange in animals, is caused by a sensitivity to and overpopulation of Demodex spp. as the host's immune system is unable to keep the mites under control.
Ivermectin is an antiparasitic drug. After its discovery in 1975, its first uses were in veterinary medicine to prevent and treat heartworm and acariasis. Approved for human use in 1987, it is used to treat infestations including head lice, scabies, river blindness (onchocerciasis), strongyloidiasis, trichuriasis, ascariasis and lymphatic filariasis. It works through many mechanisms to kill the targeted parasites, and can be taken by mouth, or applied to the skin for external infestations. It belongs to the avermectin family of medications.
Dirofilaria immitis, also known as heartworm or dog heartworm, is a parasitic roundworm that is a type of filarial worm, a small thread-like worm, and which causes dirofilariasis. It is spread from host to host through the bites of mosquitoes. Four genera of mosquitoes transmit dirofilariasis, Aedes, Culex, Anopheles, and Mansonia. The definitive host is the dog, but it can also infect cats, wolves, coyotes, jackals, foxes, ferrets, bears, seals, sea lions and, under rare circumstances, humans.
Moxidectin is an anthelmintic drug used in animals to prevent or control parasitic worms (helminths), such as heartworm and intestinal worms, in dogs, cats, horses, cattle, sheep and wombats. Moxidectin kills some of the most common internal and external parasites by selectively binding to a parasite's glutamate-gated chloride ion channels. These channels are vital to the function of invertebrate nerve and muscle cells; when moxidectin binds to the channels, it disrupts neurotransmission, resulting in paralysis and death of the parasite.
Lufenuron is the active ingredient in the veterinary flea control medication Program, and one of the two active ingredients in the flea, heartworm, and anthelmintic medicine milbemycin oxime/lufenuron (Sentinel).
Ear mites are mites that live in the ears of animals. The most commonly seen species in veterinary medicine is Otodectes cynotis. This species, despite its name, is also responsible for 90% of ear mite infections in felines.
Cheyletiella is a genus of mites that live on the skin surface of dogs, cats, and rabbits.
The health of domestic cats is a well studied area in veterinary medicine.
The combination milbemycin oxime/lufenuron is a parasite control drug in which the active ingredient, milbemycin oxime, eliminates worms, while a second active ingredient, lufenuron, arrests the development of eggs and larvae, preventing them from maturing and continuing the infestation of an animal. This combination is registered for animal use only. To achieve efficacy, the treatment is administered once monthly, together with food, in a dosage suitable for the weight of the affected animal. The usual ratio is 500 μg milbemycin oxime and 10 mg lufenuron/kg body weight. Novartis indicates the proper dosage by color-coding the packages.
Thelaziasis is the term for infestation with parasitic nematodes of the genus Thelazia. The adults of all Thelazia species discovered so far inhabit the eyes and associated tissues of various mammal and bird hosts, including humans. Thelazia nematodes are often referred to as "eyeworms".
Milbemycin oxime, sold under the brand name Interceptor among others, is a veterinary medication from the group of milbemycins, used as a broad spectrum antiparasitic. It is active against worms (anthelmintic) and mites (miticide).
Mites that infest and parasitize domestic animals cause disease and loss of production. Mites are small invertebrates, most of which are free living but some are parasitic. Mites are similar to ticks and both comprise the order Acari in the phylum Arthropoda. Mites are highly varied and their classification is complex; a simple grouping is used in this introductory article. Vernacular terms to describe diseases caused by mites include scab, mange, and scabies. Mites and ticks have substantially different biology from, and are classed separately from, insects. Mites of domestic animals cause important types of skin disease, and some mites infest other organs. Diagnosis of mite infestations can be difficult because of the small size of most mites, but understanding how mites are adapted to feed within the structure of the skin is useful.
Fluralaner, (INN) sold under the brand name Bravecto among others, is a systemic insecticide and acaricide that is administered orally or topically. The US Food and Drug Administration (FDA) approved it for flea treatment in dogs in May 2014, and approved the combination fluralaner/moxidectin as a topical treatment for cats in November 2019. The EU approved fluralaner in March 2014. Australia approved it for the treatment and prevention of ticks and fleas on dogs in January 2015. For treating mites in chickens, a solution for use in drinking water is available under the brand name Exzolt and was approved for use in the EU in 2017.
Afoxolaner (INN) is an insecticide and acaricide that belongs to the isoxazoline chemical compound group.
Lotilaner, sold under the brand name Xdemvy, is an ectoparasiticide (anti-parasitic) medication used for the treatment of blepharitis caused by infestation by Demodex. It is used as an eye drop.
Imidacloprid/moxidectin, sold under the brand names Advantage Multi for Dogs and Advantage Multi for Cats among others, is a medicine for dogs and cats to treat heartworm, fleas, sarcoptic mange, intestinal parasites and ear mites.
Sarolaner, sold under the brand name Simparica, is an ectoparasiticide veterinary medication for the treatment of flea and tick infestations in dogs. It is also used off-label to control sarcoptic mange and demodectic mange.
