What is the process of inhaling medications called?

• A. Incubation
• B. Inbreathing
• C. Gassing
• D. Insufflation

Answer: (D)

Insufflation describes introducing a substance into the body through the respiratory tract by inhalation, typically as a powder or a gas. In medical and lab contexts, this term is used when a medication is delivered by being inhaled into the nose or lungs, such as a nasal powder or an aerosolized drug. It specifically denotes administration via the airway, setting it apart from routes like ingestion, injection, or topical application. Other terms here refer to different ideas: incubation is about exposing cultures to conditions, inbreathing isn’t a standard medical term, and gassing usually means releasing gas into an environment rather than into the body. So, the process of inhaling medications is correctly described as insufflation.
