Which route involves inhaling medications that can come as aerosols, fine powders, or sprays?

• A. Inhalation
• B. Intranasal
• C. Sublingual
• D. Transdermal

Answer: (A)

Breathing in the medicine means it’s delivered by inhalation. Medications given this way are formulated as aerosols, fine powders, or sprays so they can reach the airways and lungs. This route provides a rapid, localized effect in the respiratory tract and often limits systemic exposure compared with oral routes. Other routes include intranasal (through the nose), sublingual (under the tongue), and transdermal (through the skin); these are not designed to deposit drugs deep in the lungs as inhaled aerosols or powders.
