Which of the following refers to administration of medication through the ear?

The administration of medication through the ear is referred to as "otic." This method is specifically designed for delivering medication directly into the ear canal, which allows for targeted treatment of conditions such as ear infections or inflammation. Otic medications may include drops or ointments formulated for ear use, and they are administered in a way that ensures the medication reaches the affected area effectively.

Nasal administration involves delivering medication through the nostrils, while rectal administration involves inserting medication into the rectum. Oral administration refers to taking medication by mouth and swallowing it. Each of these methods targets different areas of the body or functions differently, highlighting the specificity of otic administration for ear-related therapies.
