Which administration route involves the medication dissolving under the tongue for rapid relief?

• A. Oral administration
• B. Intramuscular
• C. Sublingual administration
• D. Inhalation

Answer: (C)

Sublingual administration relies on dissolving the medication under the tongue so it is absorbed quickly through the oral mucosa into the bloodstream. This route provides rapid onset because the drug bypasses the gastrointestinal tract and first-pass metabolism in the liver, delivering effect fast—exactly what’s needed for urgent relief. A common example is nitroglycerin for chest pain. Other routes involve swallowing (oral), injecting into muscle (intramuscular), or inhaling into the lungs, which do not utilize under-tongue dissolution and have different onset profiles.
