Why are sublingual and buccal medications rapidly absorbed?

They are metabolized in the liver.

Their action is located in the mouth.

These drugs pass directly into systemic circulation.

Blood ﬂow is diminished in these sites.

Answer and Explanation

The Correct Answer is C

Sublingual and buccal medications are rapidly absorbed because they are placed under the tongue or between the cheek and gum, where they dissolve and are absorbed directly into the bloodstream through the mucous membranes in the mouth. This allows for rapid absorption and bypasses the liver’s first-pass metabolism.
