Pronunciation: [kˈapstɑː] (IPA) 
The word "capstar" can be pronounced as /ˈkæp.stɑr/. The spelling of this word can be broken down into two parts: "cap" and "star". The first syllable "cap" is spelled with a "c" and an "a", which represent the sounds /k/ and /æ/. The second syllable "star" is spelled with an "s", a "t", an "a", and an "r", which represent the sounds /s/, /t/, /ɑ/, and /r/. The combination of these sounds and letters creates the word "capstar".
Capstar is a term that refers to a specific type of oral medication primarily used to kill fleas in dogs and cats. It is an insecticide in the form of a tablet that contains the active ingredient nitenpyram. Capstar works by binding to certain nerve receptors in the fleas' bodies, leading to the paralysis and subsequent death of the parasites.
This type of treatment is often recommended when there is a heavy flea infestation, as it provides rapid relief. Capstar begins to kill fleas within 30 minutes of administration, with peak effectiveness occurring within 2 to 3 hours. The medication is typically effective in eliminating adult fleas for up to 24 hours in dogs and up to 48 hours in cats. While Capstar quickly kills adult fleas, it does not have a long-lasting effect, so additional flea control methods may be necessary to address the entire life cycle of the fleas, such as using topical treatments or flea collars.
As with any medication, it is important to follow the dosing instructions provided by a veterinarian for Capstar to ensure its safe and effective use. While generally considered safe for use in healthy dogs and cats, it is recommended to consult with a veterinarian before administration, especially for animals with underlying health conditions or those taking other medications.
The word "Capstar" is a brand name, specifically referring to a line of veterinary medication used for flea control in cats and dogs. Therefore, its etymology doesn't originate from traditional word etymology but rather from the combination of two words: "cap" and "star".
The term "cap" likely derived from the word "capture", referring to the medication's purpose of capturing or killing fleas. On the other hand, "star" might signify the desired outcome of the treatment, which is to leave the animal free from fleas, symbolizing a star or a top rating.
It's important to note that this explanation is speculative, as the actual creation of the name "Capstar" is a result of branding and marketing decisions by the manufacturers.
