Which term is synonymous with the inhalation of medications?

• A. Insufflation
• B. Instillation
• C. Inhalation
• D. Ingestion

Answer: (A)

The idea being tested is how medications can be delivered by breathing them in. Insufflation specifically refers to delivering a substance by introducing it into a body cavity through air flow, most often the nasal passages or lungs, which requires the patient or animal to inhale the powder or aerosol. Because the administration relies on inhaling the drug to reach the mucous membranes or airways, insufflation is essentially the term that describes inhalation of medications in this context. Instillation involves placing liquid drops into a cavity or on a surface (like eye or nasal drops) rather than inhaling a substance. Inhalation is the broader act of breathing in a substance, but the term asked for here is the specific method of delivering a drug by inhaling a powder or aerosol, which is insufflation. Ingestion means swallowing the substance, not inhaling it.
