Description: 
Selamectin is formulated as a spot-on for cats and dogs to control fleas (Ctenocephalides spp.) and flea-allergy dermatitis, to prevent heartworm disease, and to control ear mites (Otodectes cynotes) in cats and dogs. It is also approved for the treatment and control of sarcoptic mange (Sarcoptes scabiei) in dogs and hookworms (Ancylostoma tubaeformis) and roundworms (Toxocara cati) in cats.
Selamectin is a macrocyclic lactone derivative of ivermectin, an anthelmintic that potentiates glutamate- and GABA-gated chloride channel opening in nematodes. At 0.1 μg/ml, selamectin is reported to inhibit growth in an H. contortus larval development assay.

Uses:
Selamectin is a topical parasiticide and also used as a veterinary antihelminithic agent on animals.
Selamectin is a semi-synthetic avermectin derivative prepared by selective hydrolysis and oximation of doramectin. Selamectin is a potent nematocide used for the treatment of endo- and exo- parasites of domestic animals, notably cats and dogs. Like the other milbemycin/avermectins, selamectin selectively binds to parasite glutamate-gated chloride ion channels and disrupts neurotransmission leading to paralysis and death of the parasite.

Mechanism of action:
Selamectin is a semi-synthetic avermectin that belongs to the class of macrolides. These drugs are neurotoxic to the parasite by enhancing glutamate-gated chloride ion channels in the parasite. The parasite becomes paralysed and dies due to increased permeability of chloride ions and hyperpolarisation of nerve cells. These drugs also potentiate other chloride channels, including those gated by gamma-aminobutyric acid (GABA). Mammals are usually unaffected because they lack glutamate-gated chloride channels and have a lower affinity for other mammalian chloride channels. Since these drugs do not normally penetrate the blood-brain barrier, GABA-gated channels in the mammalian CNS are not affected. Following topical administration, Selamectin has a high affinity for sebaceous glands and skin.
