Which route includes medications absorbed through the nasal passages, oral passage, or endotracheal or tracheotomy tubes?

• A. Oral route
• B. Inhalation route
• C. Topical route
• D. Mucus membrane route

Answer: (B)

Focusing on how drugs enter the body through breathing describes the inhalation route. When medications are inhaled, they enter the airways via the nasal passages or through the mouth, and they can also be delivered through an endotracheal or tracheostomy tube. From there, the drug is absorbed along the respiratory tract surface and, if needed, into the bloodstream, or it exerts local effects in the lungs. This route is distinct from swallowing a pill (oral route), applying medicine to the skin or mucous membranes in a localized area (topical route), or absorption through various mucous membranes in general (mucus membrane route). Inhalation specifically covers nasal and oral inhalation and airway delivery via tubes, making it the best answer for medications delivered by breathing in.
