Question

Quizplus · Accepted Answer

Sublingual and buccal medications are rapidly absorbed because they bypass the liver and digestive system and enter directly into the systemic circulation through the rich network of blood vessels under the tongue and in the cheeks. This allows for quick onset of action and avoids first-pass metabolism that can reduce drug effectiveness.
