ANS: D
Sublingual medications are rapidly absorbed into systemic circulation because of the increased blood flow to these areas and avoid the first pass effect of the liver where extensive metabolism usually takes place. These routes do not contain drug effects to the oral area and they bypass the liver. These sites are highly vascular.
