Question

Quizplus · Accepted Answer

Anticholinergic agents are not typically instilled directly into the auditory canal to treat ear problems. They work by blocking the action of acetylcholine, a neurotransmitter in the body, and are more commonly used to treat conditions such as overactive bladder or COPD. The other options listed (antibacterial agents, topical anesthetics, and ceruminolytic agents) are commonly used to treat ear problems when instilled directly into the auditory canal.
