Answer :
Final answer:
An antiparasitic otic solution is used to treat ear mites by killing the mites through ingredients such as avermectin. This substance binds to specific channels in the mites, disrupting their neuronal transmissions, causing paralysis and death.
Explanation:
The purpose of using an antiparasitic otic solution to treat ear mites is to eliminate the mites that have infected the ear. These solutions contain specific ingredients, such as avermectin and its derivative ivermectin, which are proven to be effective against parastes including mites.
These substances work by binding to glutamate-gated chloride channels specific to invertebrates, blocking neuronal transmissions and ultimately causing paralysis and death of the mites. It is important to note that healthy human ears possess cerumen (earwax) with antimicrobial properties, which maintain an acidic environment unfavorable to most parasites. However, in case of infestation, additional treatment with an antiparasitic otic solution becomes necessary.
