Which term is used to describe medications that are "pertaining to the ear"?

The term that pertains to medications involving the ear is "otic." This terminology is specifically used to refer to any pharmaceutical preparation or treatment that is administered through or relates to the ear. Such medications can include drops or ointments that are designed to treat conditions affecting the outer, middle, or inner ear.

The other terms listed do not describe medications related to the ear. "Oral" refers to medications taken by mouth, "aural" is often used interchangeably with otic in some contexts but typically relates to hearing rather than specific treatments of the ear, and "nasal" pertains to medications that are delivered through the nose. Understanding these distinctions is crucial for pharmacy technicians when dispensing medications or providing patient education.
